Biodegradation of Organic Compounds in Water

本项目的目标是研究异生有机化合物的生物降解过程，以降低这些化合物在工农业废水中的浓度。当工业或农业废物被丢弃在泄漏的垃圾填埋场或无意中排放到环境中时，就会发生固氮和有毒有机化合物对水的污染。这些有机物在工程处理系统中的生物降解是净化被有毒有机物污染的水的重要方法之一。在这项研究项目中，研究人员计划在序批式反应器(SBR)系统和摇瓶微生物实验中对两种类型的异生有机物进行生物降解，考察细胞循环和补充碳源对降解率的影响。这项工作的结果可能被用于生物反应器过程的工程设计，并将其纳入系统，以减少工业过程废水对地表和地下水的污染影响。

The objective of this project is to study the biodegradation of xenobiotic organic compounds in a process that could be used to reduce the concentration of these compounds in industrial and agricultural wastewaters. Contamination of water by zenobiotic and toxic organic compounds occurs when industrial or agricultural wastes have been disposed of in leaking landfills or inadvertently discharged into the environment. Biodegradation of these organic compounds in engineered treatment systems is one important method of cleaning up water which has been polluted with toxic organic compounds. In this research project, the investigators plan to work on biodegradation of two types of xenobiotic organic chemicals in Sequencing Batch Reactor (SBR) systems and in flask microbiological experiments, examining the effect of cell recycle and a supplemental carbon source on the rate of degradation. Results of this work are likely to be utilized in the engineering design of biological reactor processes and their incorporation in systems to reduce the pollutional effect of wastewaters from industrial processes on surface and groundwater.
