▼ Coastal environment is extremely sensitive area. The presence of oil and petroleum residues in the marine environment results from abusive spillages by ships and boats to the detriment of marine ecosystems navigation, and commercial actives such as fisheries, coastal industry development, and tourism; as well as to coastal resources when the oil reaches land. Up to now, there still isnât a complete evaluation and solution for the oil-spill risks in Taiwan. It is very important to organize and prepare an operational response for coastal oil pollution accidents. The use of computer models to predict the movement of oil helps to make best use of the various measures and equipment that can be employed in case of an oil spill accident.
In this study, the numerical model MEDSLIK is used to directly model the transport of oil for the coast sea around Taiwan. MEDSLIK is a 3D oil spill model designed to predict the transport, fate and weathering of an oil spill. The MEDSLIK oil spill model in pre-operational mode was first developed in 1997 (Lardner et al. 1998) to assist the objectives of the EU LIFE project âSubregional contingency Plan for Preparedness and response to Major Pollution Incidents in the Eastern Mediterranean-Levantineâ. The software consists of three parts, a graphical input interface through which the user enters data concerning the spill and environmental conditions, a run module that performs the computations that simulate the spill behaviors and a graphical output interface by means of which the user can examine the predictions of the model.
The aim of this study is to adopt MEDSLIK model to predict the expected state of the oil when it arrives at a given location around Taiwan. The input data includes the type of oil and its characteristics, forecasts of wind direction and strength, sea temperature, currents and conditions at sea. By using MEDSLIK oil spill model to simulate the Tzini oil-spill accident, the oil disperses between the south part of Suao Harbor and Naao. The modeling results compare well with the actual situation.
The main result is the MEDSLIK model provides the oil-spill movement pattern around Taiwan Sea and answers questions such as how much will evaporate, how much will be dispersed as fine droplets in the water, where the oil spill is most likely move to, and how soon it will get there. However, the wind input data is quantitative in this study. Future tasks must fully account the impact of regional wind field to oil movement and emphasize on anticipating likely impacts on the coast and provide an early warming and mitigation tool to plan an effective response to keep oil away from key coastal resources.

▼ Base on the Taiwan Semiconductor Industry Association 2014 statistics, IC manufacturing output of up to 22,033 hundred million NTD, more than growth of 16.7% with 2013. High-tech process required to use a lot of volatile organic solvent, that may derive the volatile organic compounds (Volatile Organic Compounds, VOCs) and emission into environment, it caused a lot of load. However, the method is putting electronic components on silicon semiconductor (products include: dynamic memory, static body memories, micro virtual processor ... etc.), and then electronic components completed by sophisticated integrated circuits (Integrated Circuit, called IC). The production process of IC is application of IC wafer oxide layer growth, lithography, etching, cleaning, impurity diffusion, ion implantation and thin film deposition techniques.
Discussion of this paper, study removed air pollution of Wafer bumping process. Wafer bumping process primarily processes is film manufacturing process, sputtering, plating or printing technique, solder directly on IC feet. In process, the wafer will be cutting into chip, and then through a series of jobs almost every step are used to a lot of acid and organic solvents and toxic gases, and become new air pollution substances. And another major source of pollution was to use solvents for cleaning.
Total VOCs emission control plan already to draw up by Environmental Protection Agency (EPA), environmental regulations of air pollution emission control plan for the industries in the future, most industries have biggest of challenges to treatment with a low concentration of high winds exhausts, and need upgrade equipment efficiency. Source reduction is the original way of improvement, should depend on VOCs raw materials usage and based on emissions from the process and efficient collection of air pollutants.
For located air pollution control equipment need to improve the operating factors for removal VOCs efficiency, and planning use condenser equipment for pretreatment. However, traditional condenser need use refrigeration to keep low temperature and need enough residence time to remove VOCs. That expected to improve traditional condenser can be high effectively and reduce energy consumption.

▼ Taiwan semiconductor manufacturing industry ranks top in the world for the production and has a great contribution to Taiwan economics. However, the industry produces a significant amount of volatile organic compounds (VOC) into the air. According to EPA of Taiwan, the annual VOC emission amounts from the industry were approximately five thousand tons, a major stationary source of VOC emission. The EPA has implemented the air pollution control regulation for semiconductor industry, in which the VOC emission amount should be below <0.6 kg/hr or the removal efficiency should be >90% for each factory . The conventional control technologies for the VOC emissions was concentration using zeolite followed by thermal oxidation. However, the high boiling points of VOC is difficult to desorbed from zeolite and it required the water to wash the zeolite. This would reduce the removal efficiency of zeolite. This control processes have high operation cost and may produce byproducts required for further treatment.
Advanced chemical oxidation process (AOP) recently has gained tremendous attention as an emerging control technology of VOC due to low treatment cost and few oxidation byproducts. The major oxidant of the technology is believed to be hydroxyl radicals, which can react organic compounds at very reaction rates. A majority of VOC emissions from the semiconductor industry are highly soluble and can be easily dissolved into water by scrubbing process. However, the wet scrubbing process can produce a significant amount of wastewater.
The objective of this study was to investigate the feasibility of using wet scrubber and O3/H2O2/catalyst process on controlling the VOC emissions from the semiconductor manufacturing industry. A full scale of process of 1000 CMM flowrate was designed and built along with a semiconductor packaging facility. Results showed that major compounds of the VOC exhaust were iso-propanol, PGMEA, PGME and methyl ethyl keton. The inlet concentrations of THC significantly varied from 50 to 600 ppmv as methane. The AOP process can removed 90-95% of VOCs and the scrubbing water can be recycled and reused at least 95%. The capital cost of the system was NT20,000,000 with the annual operation cost of NT120,000 which was only 36-40% of it for the concentration using zeolite followed by thermal oxidation.

▼ The purpose of this study is to use vertical-flow constructed wetlands (VFCW) microcosm systems to investragte the removal efficiencies of sulfate. The system was located on the campus sewage treatment plant. nn National Sun Yat-sen University. In this study, two media, gravel and peat, were installed in four different systems. The two system with same media were separated into vegetated and non-vegetated (control) ones respectively. In the test runs, the operation methods included batch type filled with water, continuous flow and integrated vertical flow constructed wetland (IVCW) with continuous flow. In batch type test, it was run under an initial concentrations of SO42 – S about 500 mg/L. The experimental results showed that the removal efficiencies were increased with increasing COD concentrations. Under the same conditions but with continuous flow operation, the removal efficiencies of SO42 – S were lower than the batch type one, which 80% could be reached. The best system for operation was P1 (peat with vegetated), in which the removal effciency reached 90%. The experimental results also showed that the vegetated systems presented higher removal efficiencies of sulfate than the non-vegetated ones. In addition, this research were increased the concentrations of SO42 – S and COD to about 1200 mg/L and 4000 mg/L respectively. The experimental results showed that the IVCW treatment system could achived greater efficiency than VFCW treatment system.
The experimental in depth research test run indicated that the anaerobic condition did not affect the removal efficiencies of ammonia by using batch type. However, nitrification was the main reaction of ammonia to nitrate in the continuous flow type systems. When ORP values were found below the -300 mV, the sulfate began to be drcreased. It was believed that if the anaerobic condition were well be established, while the organic carbon could be contented in this system, the sulfate reducing bacteria (SRB) might live, and then sulfate could be removed.
The effect of temperature on sulfate removal was generally established in this study. According to the experimental results, it was found that the activity of SRB motility was higher in higher temperature (35â) than that in lower temperature (25â).

▼ During the manufacturing process of semiconductor assembly many pollutants come with products, especially volatile organic compounds(VOCs). As VOCs with features such as penetrable, lipophilic and volatile, they can cause adverse health effects by contacting with skin and respiratory system. Key symptoms associated with exposure to VOCs include eye irritation, allergic skin reaction and nose and throat discomfort. For the environment, most of the VOCs have lower odor threshold. Only a small amount of VOCs can produce odor which leads to environmental problems and personnel discomfort. In this study, we used condensation method with washing technology to remove VOCs and organic odors. The condensation-washing device was made of stainless steel body and coated with an insulation layer. The internal device was composed of two stainless steel spray and two stainless steel cooling coils. The use of gas condensate and vapor absorption achieves the separation of some of the ingredients in the liquid.
The results showed that (1) For the organic compounds with low-boiling point such as Isopropyl Alcohol, Acetone, Trimethylamine, Dimethyl sulfide, Toluene and 2-methoxy-Propane, the removal efficiency of isopropyl alcohol and trimethylamine was more than 90%, however the removal efficiency of dimethyl sulfide, toluene, 2-methoxy-Propane and acetone was unsatisfying. Although the total removal rate was up to 90%, the rates showed between different compounds were uneven; therefore removal of low-boiling point organic compounds using this method remains further studies. (2) For the organic compounds with high-boiling point such as dimethyl sulfoxide (DMSO) and ethanolamine (MEA), the removal efficiency of dimethyl sulfoxide (DMSO) was more than 98%, while the concentration of ethanolamine (MEA) was too low to be detected, which was unable to obtain its removal efficiency. However, according to the principle of high-boiling compounds with higher absorption, its removal efficiency should be similar with dimethyl sulfoxide (DMSO), therefore, we concluded that condensation-washing equipment can proved high removal efficiency for high-boiling organics.

▼ This thesis, with the application of life cycle assessment, is meant to understand how the carbon footprint of an IC package product originates. Thus, its result will help reduce or improve the carbon footprint of the product.
The Life Cycle Inventory Analysis data include âenergy, resources, major materials, auxiliary materials, package material and wasteâ and transportation data in above items. They also include GHG data, in compliance with PAS 2050 and IC-PCR. A functional unit is an IC product with a Flip Chip package. After the data based on rationality were examined, the SimaPro software was used to calculate the life cycle assessment and environmental impact to complete the carbon footprint assessment of the product.
The percent of the carbon footprint of the analyzed Flip Chip IC was up to 83.36 %, whose die was provided by the wafer manufacturer. Judging from the outcome, to reduce the carbon footprint is in the main to cut down on that of wafer.
However, when the carbon footprint of the die was not taken into account, in the process of the semiconductor assembly, the carbon footprint mainly originated from the "Substrate", which was up to 49.0192%, and that of the electricity used in the packaging process was 44.5113%. It reasons that when a Flip Chip IC package is assembled, raw material suppliers must be required to reduce the carbon footprint of their products, which is more effective to be in demand on Substrate, and that much needed is energy saving in the assembly process.

▼ Constructed wetland treatment systems are environmental-friendly and economic technologies for wastewater treatments. The Dapeng Bay National Scenic Area Administration collected the wastewaters from the salty water aquacultural ponds and community households in the adjacent areas and discharged them into salty water type of constructed wetland treatment systems, which is quite rare in Taiwan presently. According to the surveying result of water quality in these constructed wetland treatment systems in previous study, we found that some species of macroalgae Gracilaria, were existed in some units of the wetland systems. Further, we found that the wastewater treatment efficiencies of the constructed wetland systems could be substantially enhanced by the macroalgae. Reviewing some literatures also confirmed that the macroalgae, Gracilaria, can be effectively applied to aquaculture wastewater treatment because it is able to absorb the nutrients and benefits its own growth. Besides, it can reduce the algal bloom caused by excess nutrients.
In this study, we explored the macroalgae Gracilariaâs role in those saline constructed wetland wastewater treatment systems. In the laboratory scale study, a constructed wetland model tank was designed to culture Gracilaria as a way to explore the situation of wastewater treatment. The experimental results showed that when cultured in the still water system, the macroalgae, Gracilaria, was able to increase both of the levels of dissolved oxygen and pH in wastewater. Moreover, when it was cultured in its biomass density of 10 g/L for 4 days, the removal efficiency of chlorophyll-a concentration could ideally reach to 79.10 ± 7.62 %, while the total nitrogen, and total phosphorus could reach to 47.10 ± 25.93 % and 60.49 ± 45.29 % respectively. However, the reduction of ammonia nitrogen concentration was found rather obvious only one day after culture.
Whereas, when the species of Gracilaria was cultured in the continuous flow system, we found that there were significant difference in the test result of the turbidity, chlorophyll-a, and BOD in the experimental group with addition of Gracilaria. After testing the concentrutions of chlorophyll-a over a long period of time, we found that the chlorophyll-a concentration were markedly increased when Gracilaria was not added. On the contrary, the chlorophyll-a concentration was remained stably when Gracilaria was added. When it comes to the nitrogen removal, we found that the removal efficiency of ammonia nitrogen in the experimental group could reach up to 92.27 ± 3.82 % in average. Other than that, it was found obvious decrease of the ammonia nitrogen concentration on the first day of culture. As to the test of soilâs impact on the phosphorus removal, we found that the removal efficiency in the experimental group was higher than the group without soil. Therefore, the removal efficiency was found obviously higher when there was soil. In the continuous flow system, when the species of Gracilaria was added, the removal efficiency of total…

▼ Basic oxygen furnace slag (BOF) is the by-product in the consistent steelmaking operation process. As reusable and recycled resources, a lot of coarse parts have been used on engineering materials due to its hardenss and abrasion resistence. Regardless of the reuse with BOF, slag <3.5mm including free CaO/MgO are easily swelling to disintegration. Emanating from mine waste rock and tailings, AMD is primarily a function of mineralogy and the availability of water and oxygen. Upon exposure to oxidizing condition, sulfide minerals easily form acid-rich water with sulfate and hydrogen ions. Characterized by low pH value and high concentration of heavy metal, the AMD is recognized as one of the most serious environmental problem in mining industry. This study presents two parts of experiments, (1)the batch experiment with three different particles size of slag producing the best liquid-solid ratio, (2)making permeable material in column leaching tests and tank leaching test to discuss both the optimization of contact time, pH neutralization balance, and partial removal of copper and iron from artificial AMD.
While value reaches to 7~8 pH, results from the batch experiments show the maximum removal of iron and copper ions. A ratio of 10g slag to 100L AMD was found to be the optimum at which both copper hydroxide and ferric hydroxide precipitation. Based on the L/S ratio at 10:1, the column leaching test were conducted to assess the maximum treatment capacity by using continuous flow measuring the best accumulation ratio at 1.0~2.0 and the residue of iron and copper ions beneath 0.1 ppm. In order to applied on on-site treatment, additional experiments in five permeable specimens were managed which indicate the highest slag replacement attains both the better porosity and neutralization in AMD.

▼ The emulsified carbon-releasing substrate (ECS) is commonly used in bioremediation that can promote the microbial growth and enhance biodegradation process. The remediation object of this study is a local trichloroethylene (TCE) contaminated site. Based on the direction of the groundwater flow, there are five deep wells were dug in the remediation site, i.e. P64, P48, TW11, P22, and P24 respectively. P22 is the injection well and the others are sampling and monitoring wells. Polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) technique was used to monitor the microbial diversity during the remediation process. The real-time PCR was also used to detect the quantity of Dehalococcoides species as well as 3 dehalogenase genes (TceAãVcrAãBvcA) to evaluate the dechlorination activity. Results show that well P22 contained the most microbial diversity than all other wells because the injected ECS encouraged the microbial growth. The qPCR studies revealed that the content of Dehalococcoides species was related to pH value, the lower the pH value the less Dehalococcoides species present. However, the pH value did not overly affect the growth of Dehalococcoides species. The oxidation-reduction potential(ORP) indicated that the contaminated site was anaerobical and could stimulate the reductive dechlorination process. A hydrogen production Clostridium butyricum bacterial strain was isolated from the groundwater. The hydrogen produced by this strain can be used as an electron donor for TCE dechlorination. The expression of hydA gene of the anaerobic batch culture reached the highest amount (ie. 1.7Ã 1011 gene copies / L) at 28 day. The steady decreasing of TCE concentrations suggested that C. butyricum could provide hydrogen continually to assist the anaerobic dechlorination reaction.

▼ Taiwan is surrounded by the sea and is situated in a developing shipping area in Southeast Asia. The increase in navigation around the island leads to a significant increase in the probability of accidents and therefore to the occurrence of pollution events. When oil leakage occurs, it is of utmost importance to remove it as fast as possible. Though the use of physical, chemical and biological methods, men are able to clean the area to its former state. However, when an accident occurs, the processes of communicating, organizing and dispatching human power and equipment often takes a precious time, which reduces the effectiveness of the intervention. In this regard, we present a Decision Support System (DSS) for assessing the contingency response capacity to marine oil spill. This DSS combines an expert system for the evaluation of the equipments that are needed, with a spatial Integer Linear Programming (ILP) model for the selection of these equipments from different storing sites. It is hoped that this DSS can provide decision makers with an increased ability to react quickly to any pollution event, and thus, help protect our coasts from the negative impacts of oil pollution.

▼ The more booming of development of technology in Taiwan, the more attention is given to marine resources. The exploitation of marine resources brings outstanding benefits for local economy, but it also causes a huge impact on the marine ecosystem. In order to mitigate the impact of marine pollution incidents on Taiwanâs marine ecosystem, much more importance should be attached to implementing aggressive ways of the prevention and control of marine pollution and the establishment of the Regional Marine Pollution Emergency Response System. In Taiwanâs existing response mechanism for dealing with domestic marine oil pollution incident, the local competent authority is responsible for most heavy workloads in the initial phase of response. This is difficult to reach an effective way of collaboration. The local competent authority has insufficient response resources (i.e. personnel and equipment) or deficiency in notification process that will result in overlook the appropriate response to marine oil pollution incident in the first instance. In Taiwanâs local competent authority, personnel who in charge of managing marine oil pollution equipment are mostly short of qualified mechanical experience. The response equipment is vulnerable to poor maintenance, may further impact the operations of mechanical equipment for spilt oil recovery and mitigation of pollution spreading.
This study compressively assesses the applicability and adequacy of Taiwanâs capabilities in response to marine spill contingency by sorting out the application of mechanical recovery equipment for oil pollution response, the characteristics of spilt oil, foreign and domestic organizations for oil pollution response, and the analysis of risk area for vessel-based spills in Taiwan waters. On top of that assessment, this research further studies the set-up of weathering conditions for spilt oil, the estimation of clean-up capabilities at sea and on shore, and developing a methodology for assessing capabilities in response to marine spill contingency. The domestic tactics of applying mechanical equipment for spilt oil clean-up are also discussed, and further recommendationsï¼i.e. options in the situation of equipment shortage, viable direction for improvement of capabilitiesï¼ are made for enhancing operational efficiency in response to future marine oil pollution emergency.

▼ Swine wastewater is one of the major pollutions in Taiwan. The abundant nutrition and organic matters in it may lead eutrophication of water body. Meanwhile, the low dissolved oxygen level and high suspended solids concentration may also make it more difficult to handle the wastewater treatment. At present facility of swine wastewater in Taiwan is the three-process treatment which includes the solid-liquid separation, anaerobic digestion, and activated sludge system. Even though the three-process treatment is widely used, the efficiency of sediment and filter effectively to remove the nutrition, e.g., ammonia and phosphate is still in question. On the other hand, the activated sludge system is a difficult technique that the swine farmers canât easily to operate. Based on these reasons, an efficient swine wastewater treatment process should be established. In this study, we replace the activated sludge system in three-process treatment with the horizontal biofilter (HBF) and subsurface system constructed wetland (SFSCW) to assess the practicability of improving the traditional process. HBF is a fix-biofilm system which is superior to the suspended growth of activated sludge system by its simple operation and no need to return the sludge from the final clarifier. Porosity in the gravel of SFSCW and the root zone of Canna indica can also help to remove the nutrients from the outflow of HBF. The tested HRT (hydraulic retention time) has been controlled at about 30 hours and results show that SS, BOD and COD removal efficiencies as 84.07%, 86.48%, and 68.45%, respectively. HBF and SFSCW provided approximate 70~80% and 10~20% removal efficiencies, respectively. This design of combining HBF and SFSCW system has high potential to treat the swine wastewater, and adding the backwash unit may further facilitate the operation in the future.

▼ Ever since humans began using cargo by sea to transport oil, oil spill incidents have occurred on different scales in different environments. Oil leaks by cargo tankers on the high seas have a bigger and more serious impact on the environment. Among the many oil spills in the ocean, the most serious was the Exxon Valdez incident in Alaskaâs Prince William Sound (PWS). While it may not have been the largest spill in terms of the volume of oil leaked, its effects were far-reaching; the location of the spill was in the sensitive area between the temperate and subtropical zones, and it was home to many fish, migratory birds, and mammals. Therefore, this location has become an important place for researchers to study the environmental and biological impacts of an oil leak. In the past, there have been several studies conducted from various perspectives and in various stages. In 2001, the Greek oil tanker The Amorgos ran aground near Kenting National Parkâs Long-Keng Environmental Protection Zone and seriously damaged the ecological environment. Taiwanese studies on the ecological impacts of oil spills include investigations and evaluations done on a short-term basis, and have been mainly focused on contingency plans and designs, evaluation systems, and handling technology. Thus, the purpose of this paper is to use related studies conducted in Alaska PWS to evaluate the ecological system in the Long-Keng area and to assess the long-term impacts of an oil spill in the ecological sensitive area of Taiwan.

▼ The pollution of soil and groundwater have increased due to the leakage of ptrolium products and organic chemicals in the country recently,and Taiwan face with small region and dense population,so the pollution maybe exposed through relevant way such as quality of water,soil,air,crop and fish and so on to affect human health and cause risk of jeopardise directly or indiretly. The study is to aimed at chlorinated compounds for domestic,and use methods of risk assessment to analyze necessity and urgency of renovation for be contaiminted compound and downstream influence.And then according to result to make relevant management strategies and projets to control risk level and influence for contaiminated compound.
In this study,we collect information relate to case,in accordence to health and risk assessment methods for soil and groundwater contaminated sites and some softwares of CRYSTAL BALL and BIOCHLO by Environmental Protection Bureau to estimate the site which was evaluated chlorinated compound (trichloroethylene,TCE),and considerate whether they affect residents healy nearby,use some hydrogeological survey of sites to process second-level health risk assessments.
First,use commercial software of CRYSTAL BALL execute uncertainty and sensitivity analysis. Not only does the analysis probe into overall parameters variaty how to affect risk value but also they process analysis and results by different combinations of paremeter.From this result, we can confirm that the large parameter values for affecting risk is transmission of pollutants and is similar to previous studies assessment and analysis.Other parameter cause less influence for risk variaty such as age level of receptor,group,the way of contact,time and water quntity.The study discovers TCE pollutants concentration will make change of risk value by accompany with groundwater move to downstream distance. That means receptor of distance of contamination resource cause large influence. The far distance represents can product the larger function for TCE pollutant, and causes less cancer risk for receptor, conversely, it causes higher cancer risk.
Subsequently, we also use BIOCHLOR assessment software by U.S.A Enviromental Protection Bureau. from the result to determine whether the site have potential of anaerrobic reductive dechlorination or not and estimate natural attenuation possibility.The actual situation of the site gets the three score in the weight total.This display do not prove that chlorinated compounds can procedd biogical decomposition in the anaerobic invironment without more correct value in the stage.We recommend looking for another renovations.
The study selects more important sensitive parameters through risk assessment result for the site and work out the way of renovations which is suitable for this case by schedule of object. The investigation has found that residents indeed extracted groundwater for agriculture irrigation, but not drank water directly. In order to avoid the worst situation happens from the view of risk, we will consider two…

▼ The objectives of this study are to use phytoremediation ecotechnology to improve the long-term soil pollution contaminated by petroleum and its refined products, and to explore the influence of environmental factors to the effective degradation of TPH.This study is divided into three stages.First, we selected the biofuel crops seeds to test their diesel fuel pollution tolerance.The crops include soybeanãsunflowerãcanola and corn.This four Taiwanese common energy crops were selected to manually configure three levels of diesel fuel pollution(1000ã5000ã10000 mg kg-1)in soil test the seed tolerance experiments.The experimental results in the first stage exhibited that the best energy crop species and non-edible crop(Jatropha),are selected in second phase for contaiminated soil degradation experiment to explore the possible influence of enviromented factors,such as soil moistureãpHãtotal plateâ¦etc,and to explore the applied fertilizer to increase soil nutrients,whether it will affect the degradation of diesel pollution.Finally, in the third phase, the energy crops were used in the oil-contaminated site to assess their decontamination efficiency. From June 2011 to November 2011, the experimental results shown in the first phase of seed tolerance test, for a period of 30 days showed that the soybean diesel-contaminated soil presented the best tolerance.Although the germination rate was increased with the concentration from 80% to 27%, it showed the best growth conditions.Therefore, in the second phase of test run, the speices of soybean and jatropha were selected prepared with concentrations of 1745ã6271 and 10072 mg kg-1 dry soil. After 90 day for phytoremediation, soybean group(S) were found that the residual concentrations in soil were measured equal to 524ã809 and 1913 mg kg-1 dry soil,with the removal rates of 69.97%ã87.09% and 81.01% respectively.The concentration level of 10000 ppm was found not reach our control standard of 1000 ppm. The soil planted by jatropha(J) showed that residual concentration in soils equial to 303ã1864 and 4837 mg kg-1 dry soil, with removal rates equal to 82.61%ã70.27% and 51.98% respectively.Through statistical regression analytical results, the soybean can handle up to a concentration of 5300 mg/kg for diesel, while jatropha can handle up to 2170 mg/kg in this system. Except for the concentration level of 1000 ppm can reach our control standards, the other two groups were found below the control standard. To improve the removal efficieneies, it was suggested that phyto remediation time can be extended.

▼ Anoxic ammonium oxidation (ANAMMOX) is biochemical process based on the theory of autotrophic nitrogen removal through nitrite to nitrogen gas. Unlike heterotrophic denitrification requiring adding extra organic carbon sources, the process of ANAMMOX can remove ammonia to nitrogen gas from wastewaters characterized by a low content of organic materials.To reach the purpose, in this study a vertical-flow constructed wetland(VFCW) system with deep depth and high HRT was used. The VFCW system was installed with gravels and filled with some anaerobic sludge for ANAMMOX bacteria growth in the system.
The three VFCW systems were all filled with gravels(20-40 mm in diam) as media, and controlled by three different conditions: anaerobic sludge seeding and with vegetation(Phragmites), anaerobic sludge seeding without vegetation, and without both seeding and vegetation, respetively. Artificial wastewater, with NH3 levels(50 mg N/L) and hydralic retention time (HRT) was controlled as 1 day for all three systems. The experimental results showed that nitrite was found in higher amounts than nitrate in depth of 20cm of the system, while nitrite was decreased down in large amounts with low dissolved oxygen (DO) of 0.5mg/L found in 40cm depth of same system, which was meant that ANAMMOX might occur in this area learned by nitrite removal through Anammox bacteria probably. It was inferred that for the VFCW systems used in this study, ANAMMOX occurred obviously in the areas of 40cm depth. For further study throuth the bio-technique of qPCR, the results exhibited that Anammox bacteria indeed existed in the VFCW systems of this study.

▼ Wastewater has been a big issue for the environment. Carbohydrates, nitrogen, phosphorus, and other nutrients, when in the water, will cause algae to multiply, lead to low dissolved oxygen to produce an anaerobic environment. Under the action of anaerobic bacteria it will produce pollutants and odor substances. Then it will affect the quality of water and air. So this is an important issue of environment.
ããThe study notes constructed wetlands that can effectively reduce nutrient concentrations in domestic wastewater. Dapeng Bay National Scenic Area has many salt constructed wetlands to treat the domestic and aquaculture wastewater from surrounding communities, with a variety of wetland plants, animals and microorganisms in the different function of water treatment unit.
ããWe selected a wetland in Dapeng Bay as study sites: Datam constructed wetland, with an inlet that is domestic wastewater. It also has shallow pond, swamp, sedimentation pond, deep pond and other areas. Sampling aspect is continuous sampling that takes a season for four days, and every six hours take a water sample for analysis. Through the experimental analysis of Suspended Solids, ammonia nitrogen, total Kjeldahl nitrogen, nitrite, nitrate, orthophosphate, total phosphorus, Biochemical oxygen demand, and total carbon water quality index. The aim is to investigate the concentration of pollutant-change and observe the different seasons of the contaminant reduction condition. This is so as to find out the environment and climate which can effectively reduce the concentration of pollutants in wastewater.
ããSpring has a better removal efficiency. Suspended solids removal efficiency of 43.3%, total phosphorus of 41.2%, total nitrogen of 35.6%, biochemical oxygen demand of 34%. Due to summer's high temperature accelerated microbial growth in the deep pool, resulting in wetland pollutant concentration increased. The results showed that the water quality of wetland and the total organic carbon and total nitrogen in soil were positively correlated with methane (CH4) and nitrous oxide (N2O) released from greenhouse gases, especially in summer.

▼ In the past, the Taiwanese government was committed to implementing industrial development policies that emphasized economic development. These policies subsequently led to the destructions of Taiwanâs ecology. However, the rise of domestic environmental awareness and industry transformations have gradually increased peopleâs attention to measures that protect the environment, in which the concept of artificial wetlands serves as one of these measures. Artificial wetlands are mainly divided into constructed wetlands and created wetlands. Constructed wetlands are artificial wetlands that have been ameliorated by improving their water quality. By contrast, created wetlands are wetlands that entail recovering ecological habitats or creating nature-like biological habitats to provide or replace existing biological habitats. The Yuanzhonggang Wetland Park is a wetland park located in Nanzi District, Kaohsiung City. Because the region is located next to an area to be built into a second-generation naval ship base, the construction of the naval ship base will inevitably exhibit an effect on the habitat environment. Therefore, the Yuanzhonggang wetlands are classified and positioned as âcompensatoryâ created wetlands and efforts to recover their ecological habitats have been made accordingly. The goals are to recover mangroves, emphasize the use of native tree species, and serve the functions of flood control, water purification, landscape-based recreation, and ecological education. Located in the Nanzi District, Kaohsiung City, the Yuanzhonggang Wetland Park measures 29.41 ha and is divided into an east and west region by the Nanzi Wastewater Treatment Plant. The east and west wetlands are freshwater and brackish water-type ecosystems, respectively, in which the water for the east region primarily comes from secondary effluents discharged by the Nanzi Wastewater Treatment Plant. The said effluents are subsequently purified by constructed wetlands before being released into the Dianbao River. The west region is located in the tidal river section of the Dianbao River estuary, where brackish water of the Dianbao River flows into the Yuanzhonggang Wetland Park at high tide. In this study, water purification results of the constructed wetlands in the east and west regions were assessed to determine whether they achieved the desired effectiveness. Water purification samples were collected once a season, where spring and neap tides were obtained at high and low tides and analyzed for water quality including their biochemical oxygen demand (BOD) as well as ammoniacal nitrogen, total Kjeldahl nitrogen, nitrite, nitric acid, orthophosphate, total phosphorus, and total carbon contents. The results of the east and west regions were subsequently compared. According to the results, of the four seasons, constructed wetlands of the east region and created wetlands of the west region displayed the most optimal pollution removal effect in the hot seasons (i.e., summer and fall). For spring and neap tides at the west outlet, total phosphorus…

▼ Constructed wetlands (CWs) can effectively remove pollutants from water environment. Most of the species planted in constructed wetlands, which may assist the function of water purification of wetlands, are freshwater hydrophytes, such as reeds and cattails that are not suitable for treating saline wastewater or mariculture wastewater. Therefore, in this study we will investigate the use of salt-tolerant salt marsh species of Spartina alterniflora as the hydrophyte planted in CWs to treat the domestic wastewater containing high salinity. S. alterniflora has been identified as harmful exotic species, due to its strong vitality and adaptability on coastal mudflats, resulting in invading the habitats of native hydrophyte species. However, some studies pointed out that S. alterniflora has the ability to degrade organic matter and nutrients in wastewater. In this study, S. alterniflora collected from Gaomei Wetland were used as the main hydrophyte species in the lab scale SSFCW microcosms, and fed by the secondary treated effluent from the campus WWTP of
NSYSU, which were adjusted into different salinities, and then we observed the growth status and analyze the effluent from the CWs. In the first test run of the experiments, we observed whether S. alterniflora could adapt to saline environment by gradually increasing the salinity, while in the second test run, a batch type of CW systems were used to analyze the effluent of the S. alterniflora. In the third test run, it was changed into continuous flow from the CW systems in order to make the study more similar to the nature state. The experimental result showed that the CW systems vegetated with S. alterniflora could remove 96% of the phosphate and 91% of the TN, while in the third test run, it was found that the non-vegetated CW systems performed better than the vegetated ones.

▼ The industry has made great progress since the 18th Century. It was accompanied by a large increase in carbon dioxide emission through the burning of fossil fuels, which becomes the most important greenhouse gas (GHG) presently. The GHGs emitted from wetland systems are mainly carbon dioxide (CO2), nitrous oxide (N2O) and methane (CH4), while can depress the carbon sink effects of wetlands and enforce the greenhouse effects of Earth.
Recently, more studies about carbon sink effects were concentrated on âblue carbonâ. Blue carbon is defined as the carbon sinks and stocks capacity in marine environment and on coastal ecosystems. The natural wetlands approximately account for 20% of the world's carbon stocks, especially for coastal wetlands, including salty marsh, mangrove swamps, and seagrass beds. In this study, three main GHGs and soil properties were monitored and analyzed for different vegetation areas on Kaomei Salt Marsh Wetland from October 2016 to June 2017. The wetlandâs carbon stocks and blue carbon sink effects were then evaluated by those data collected from GHGs emission and soil properties.
Soil carbon was mostly distributed in the depth of 0~15 cm in soils of Kaomei Salt Marsh Wetland. Soil carbon stocks in the soils of the habitats vegetated by Bolboschoenus planiculmis, Sporobolus virginicus, Phragmites communis, Spartina alterniflora, mudflat area, sandstone area 1 and sandstone area 2 were measured equal to 304 t C, 133 t C, 116 t C, 63 t C, 268 t C, 1512 t C, and 1698 t C, respectively. The total soil carbon stocks were then calculated equal to 4096 t C. The soil carbon stocks are affected by different area with different vegetation and soil types.
Continuous monitoring data of GHGs emitted from different habitats in the Kaomei Salt Marsh Wetland, transferring to carbon dioxide equivalent (CO2e) through the global warming potentials (GWPs) for the three main GHGs, the carbon budget flux for Kaomei Salt Marsh Wetland are shown as following: Spartina alterniflora habitat is 2042.88 g CO2e m-2 yr-1, and Sporobolus virginicus habitat is 30.55 g CO2e m-2 yr-1, which exhibit carbon source and present positive greenhouse effect, while Phragmites communis is -162.36 g CO2e m-2 yr-1, Bolboschoenus planiculmis habitat is -704.66 g CO2e m-2 yr-1), and mudflat is -1259.48 g CO2e m-2 yr-1, which showed carbon sink effect, and exhibit negative greenhouse effect.

▼ The purpose of this study is to study the feasibility of treatment of mercury contaminated soils by phytoremediation. The plant species selected in this study were evaluated for their best endurance ability against mercury and best accumulation ability for mercury by pot tests. The selection rules of plant species used in the experiments of this study are the salt-tolerant and drought-tolerant native plant species located in the seashore of Taiwan, which include Millettia oraria, Imperata cylindrical, Phragmites australis, Arundo formosana Hack., Miscanthus floridulus and Saccharum spontaneum. All these plant species were planted into the pot soils with mercury for 150 testing days in semi-open space. The experimental results showed that the six plant species used in this study were able to absorb mercury through phytoextraction and phytostabilization. It was also found that the roots, shoots and leaves could absorb heavy metal mercury for all these six plant species. In addition, although the amounts of mercury accumulation might be high in the plant tissues, the concentration of mercury in plant tissues might be not high, which was not strictly correlated. However, the growth rate of Saccharum spontaneum was found the best, but its mercury accumulation ability was less. It was presumed that Saccharum spontaneum was not easy to absorb mercury, but mercury accumulation ability was better. Finally, the control tests for these six plant species exhibited no significant change in the mercury accumulation ability. Therefore, it can be inferred that the six plants do not absorb mercury vapor in the atmosphere. It was concluded that although the mercury accumulation capacity in plant tissues was highest in Millettia oraria, the highest concentration of mercury accumulated in the plant tissues was Arundo formosana Hack. Therefore, it was recommended that we can use the plant number per area to evaluate which plant species has the best phytoremediation ability for mercury contaminated soils.

▼ The nutrient salts and carbon dioxide (CO2) required for the growth of microalgae can be respectively obtained from waste water and flue gases emitted by wastewater plants and power plants. Therefore, a microalgae culture system can simultaneously attain multiple goals such as mciroalgae cultivation, water purification, and carbon storage. The produced microalgae can be used as fish feeds or processed and converted to economic by-products, including fertilizers, biodiesels, and health food. The growth of microalgae is affected by nitrogen and carbon sources as well as other environmental factors such as illumination.
Experiments were first conducted to investigate the effects of various environmental and operating factors on the biomass and oil accumulation of Nannochloropsis oculata (TF-11); these factors were nitrogen concentration, phosphorous concentration, salinity, pH, aeration ratio, high- and low-concentration nitrogen sources, light intensity, and carbon sources. According to the experimental results, the most influential growth factors, namely, salinity, nitrogen sources, and carbon sources, were selected to optimize the cultivation cost. Finally, experiments were conducted to examine whether N. oculata (TF-11) can be used to perform secondary treatment for fish farm and municipal wastewater to purify water and produce high-biomass algal solutions as animal feeds.
Applying various salinity levels (0.76â40 PSU) confirmed the euryhaline property of N. oculata (TF-11); in particular, the microalgae could grow under a salinity of merely 0.76 PSU. Regarding light intensity (300â6000 lux), the growth of N. oculata differed nonsignificantly between 3000 and 6000 lux.
The experiment on municipal wastewater showed that N. oculata completely removed 30.36 ± 0.54 mg Lâ1 total inorganic nitrogen in approximately 5 days, and the experiment on fish farm wastewater confirmed that the algae completely removed 2.95 ± 0.24 mg Lâ1 total inorganic nitrogen in approximately 3 days, attaining a removal rate of 76%.
The culture optimization experiment on the CO2 influx rate showed that the culture medium only required a CO2 influx of 4.4 mL minâ1 Lâ1 to reduce the pH by 2.4; this influx rate was only 1/13 of the conventional method.

▼ Constructed wetlands (CWs) utilize the natural mechanisms in wetlands to remove pollutants by physical, chemical and biological processes. CWs are one of the ecological engineering methods to purity water quality and has been experimented to assess their capabilities to remove nutrients from eutrophic water bodies of lakes and reserviors. This
study was carried out to compare the removal of nutrients between vegetated and unvegetated CWs. The vertical flow bed was placed in the upstream, while the horizontal subsurface flow bed was set in the
downstream. Cannaceae was selected to plant in the vegetated CWs. Two kinds of hydraulic retention time (HRT), 3 days and 7 days, were applied and compared with each other in this study.
The experimental results show that no significantly difference between vegetated and unvegetated systems. The removal efficiencies of SS, BOD,
NH3-N, TP are measure equal to about 80%, 75%, 80% and 65%, respectively, while the removal efficiencies of TN, OP, and COD were reached about 50% and larger. Both of the two systems show high
efficiencies for nutrient removal. In the comparison between the two kinds of HRTâs, the HRT controlled at 3 days presented higher removal efficiencies than that controlled at 7 days.

▼ Alkylphenol polyethoxylates (APEOs), a class of nonionic surfactants, have been widely used for industrial, agricultural and household applications. The biodegradation metabolites of APEOs, such as nonylphenol and octylphenol, are more persistent and known to disrupt endocrine function in wildlife and human. These compounds are also recognized as endocrine disrupting chemicals (EDCs). The objectives of this study were to investigate the distribution and removal efficiencies of EDCs, including nonylphenol diethoxylates (NP2EO), nonylphenol monoethoxylates (NP1EO), nonylphenol (NP) and octylphenol (OP), of wastewater treated by the constructed wetland systems along the Dahan River and around the Dapeng Bay, respectively. In addition, the method of risk quotient was used to evaluate the potential ecological risk of APEOs to aquatic organisms in current study.
The water samples collected from 32 sampling sites in the Dapeng Bay National Scenic Area including Datan, Pengcun and Linbain right bank constructed wetlands. The samples were then concentrated by solid phase extraction, and analyzed for target compounds by HPLC/fluorescence. According to the results, nonylphenol diethoxylates, nonylphenol monoethoxylates, nonylphenol and octylphenol were found approximately equal to 29.9, 47.3, 20.5 and 57.7 %, respectively of the samples from three constructed wetlands with concentrations ranged from <3.3 to 968.7, <3.3 to 226.5, <1.3 to 238.4 and <1.0 to 1458.7 ng/L, respectively. Temporal variation of APEOs showed a decreasing in the order of summerï¼springï¼winterï¼autumn. The removal efficiencies of APEOs in these constructed wetlands showed a decreasing order of Datan wetlandï¼Pengcun wetlandï¼Linbain right bank wetland.
In addition, the samples collected from 18 sampling sites from the constructed wetlands along the riparian of Dahan River including Daniaopi, Hsin-Hai Bridge Phases I and II constructed wetlands. According to the results, nonylphenol diethoxylates, nonylphenol monoethoxylates, nonylphenol and octylphenol were found approximately equal to 91.9ã84.8ã17.1 and 73.7 %, respectively of samples collected from three constructed wetlands with concentrations ranged from <3.3 to 11191.5, <3.3 to 6069.0, <1.3 to 671.0 and <1.0 to 5581.9 ng/L, respectively. The removal potential of APEOs in these constructed wetlands showed a decreasing order of Hsin-Hai Bridge Phases IIï¼Daniaopiï¼Hsin-Hai Bridge Phases I constructed wetland.
Regarding the ecological assessment in this research, the calculated risk quotients were up to 30 times higher in the constructed wetland systems of Dahan River than those in the Dapeng Bay National Scenic Area, indicating that the existing concentrations of these EDCs in wetland systems might cause potential ecological risks to aquatic organisms. Furthermore, the decreasing risk quotient from influent to effluent indicating the capabilities of treating alkylphenolic compounds in these constructed wetlands.

▼ A combination of PCP, mercury and dioxin polluted site in Southern Taiwan causes great damage to the natural environment and endangers the health of nearby residents. The goal of this study is to isolate mercury resistant microorganisms from the polluted site and develop an in situ bioremediation technique. Because the concentration of mercury pollution in the polluted site is about 50 ppm, the medium used to isolate bacteria was designed to contain 60 ppm mercury ion. After mercury-resistant bacteria were isolated, PCR specific primers were applied to detect whether the bacteria contain merA gene or not. Identification of bacteria were based on their 16S rDNA sequences. In this study, three bacteria were isolated, designated as B37, A45 and A46. Species identification showed that B37 was closely related to Enterobacter cloacae while A45 and A46 were associated with Pseudomonas sp.. All three bacterial strains were also confirmed to grow well in 100 ppm Hg2+ media as well as under seawater salinity (3.5%). RT-PCR and real time PCR analysis revealed that the expression of merA gene could be induced by 10 ppm mercury ion in all 3 bacterial strains. Mercury ion removal batch studies exhibited that A45 strain in NB medium, combination of 3 strains in PMM medium, and B37 strain in LB mediums possessed the best treatment effect. After 12 days of incubation, 54.4%, 89.0% and 88.6% of mercury ions could be removed respectively. This study shows that these three bacterial strains are useful candidates in future bioremediation.

▼ In this study, the possibility of driving Anammox process in constructed wetland systems is investigated. The experimental designs are based on completely autotrophic nitrogen removal over nitrogen removal over nitrite (CANON), which can couple Anammox process with partial nitriï¬cation in one single unit. To reach the purpose, in this study a vertical-flow constructed wetland (VFCW) system with deep depth and high RT was used. The VFCW system was installed with gravels,on which biofilm was formed and attached, and fill with some anaerobic sludge for suspension growth in the system. In order to inhibit the effects of heterotrophic denitrification, low levels of chemical oxygen demand (10.14-11.59 mg/L) were controled in the inflow of the systems.
The experimental results show that the process of nitrification is very significant in the first day of test run, while the concentrations of DO were decreased down to below 1 mg/L, and the concentrations of NH4+-N were decreased with increasing NOx(NO2 – N+NO3 – N). Comparing with the amounts of NH4+-N decreased, the amounts of NO2 – N increased was far less than it, while the same situation was shown until the fifth day. The percentage of TN removed were reached to 97.5% (PS) in the fifth day, which was the end of test run. Though the test of Polymerase Chain Reaction (PCR),it was helpful to know the Anammox bacteria did exist in the VFCW system, which might occur from the first day to the fifth day. It was also shown that the plants in VFCW system could enhance the removal of TN. That was because the plants could absorb NO3 – N, which was produced by those processes like nitrification and Anammox.

▼ In this study, we used salt tolerance and freshwater aquatic plants species in subsurface flow and aquatic plant systems to treat swine wastewater effluent. The freshwater aquatic plant species, including water hyacinth and water cabbage, have been studied in Taiwan, China and other countries. This two species of aquatic plants have been applied in many cases, and have the characteristic of rapid growth, which might cause ecological pollution. However, some studies showed that the wastewater with high salinity would limit the growth of aquatic plant species, and even might cause to death. Therefore, in this research we used salt tolerance plants(Bermuda grass, Sea purslane and Suaeda nudiflora) to treat swine wastewater, and expect that they could reduce the impact to aquatic plants from swine wastewater, so that it could increase the removal efficiency. Salt tolerance plants in subsurface flow constructed wetland systems, initially showed high efficiency for removal of TP, by five-fold dilution of wastewater with the highest removal rates of 52.2% and primary removal rate of 31.8%. Salt tolerance plants in subsurface flow constructed wetland systems removal of TN, presented stock solution removal rate of 67.5%. The rate for TP removal in water hyacinth aquatic plant constructed wetland systems for was measured up to 61.9% for the stock solution, while water cabbage aquatic plant constructed wetland systems could be up to 39.2% for the five-fold dilution. The rate in water hyacinth aquatic plant constructed wetland systems for wastewater TN removal was up to 63.1% for the stock solution, while water cabbage aquatic plant constructed wetland systems could be up to 50.0% for the five-fold dilution. For the overall system, the rate of change of the electrical conductivity was decreased to 34.3%. The removal wet weight of Bermuda grass and Sea purslane were measured equal to 2.35(kg/m2) and 1.67(kg/m2) per month respectively, while the removal of nitrogen was 12.59(kg/m2) and 7.18(kg/m2) per month respectively and removal of phosphorus was equal to 0.82(kg/m2) and 0.82(kg/m2) per month respectively. The removal wet weight of water hyacinth and water cabbage were measured equal to 7.57(kg/m2) and 2.71(kg/m2) per month respectively, while the removal nitrogen was 15.75(kg/m2) and 4.93(kg/m2) per month respectively, and removal phosphorus was 1.57(kg/m2) and 0.46(kg/m2) per month respectively.

▼ The first objective of this study was to investigate the removal efficiency of the endocrine disrupting chemicals(EDCs), including phenolic compounds such as nonylphenol(NP), octylphenol(OP) and bisphenol A(BPA), and natural and synthetic chemicals such as estrone(E1), 17β-estradiol(E2), estriol(E3), diethylstilbestrol(DES) and 17α-ethinylestradiol(EE2) of wastewater treated by the constructed wetland from the Wan-Dan embankment. The second objective was to assess the estrogenic activity with different treatment units using the T47D-KBluc bioassay.
According to the T47D-KBluc assay, the estrogenicities in influent(In), grit chamber(GC), pre-aeration tank (AT), the contact aeration tank(CAT), aquatic plants area (PA) and effluent(Eff) were ranged from 1.18 to 30.4, 0.85 to 27.74, 0.46 to 3.32, 0.53 to 6.48, 0.48 to 13.44 and 0.52 to 21.16ng 17β-estradiol(E2) equivalents/L. The results of the different flows from the constructed wetland, 100CMD, 200CMD, 350CMD and 500CMD showed the mean removal efficiency of estrogenic activity, 64%, 42%, 36% and 31%, respectively.
In chemical analysis, the samples were pre-concentrated by solid phase extraction, and analyzed for target compounds by LC-MS/MS method. According to the results, estrone, estradiol, ethynyl estradiol and diethylstilbestrol were not detected throughout the study period. The detection frequency of estriol, nonylphenol, octylphenol and bisphenol A were approximately 16%, 3%, 21% and 1%, respectively. The removal efficiency of estriol and octylphenol, showed was larger than 99% and 37%,respectively. Nonylphenol canât be removed in the system. Bisphenol A detected only in one sample located in the aquatic plants area.
Comparison of to the chemical analysis and bioassay, the concentration of estrogenic activity ranged from ND to 0.46ng / L and 0.48 to 30.3ng / L, respectively. Bioassay could be used to detect known and unknown estrogenic compounds, as a rapid and effective detection method.
