The objective of this project is to determine the feasibility of using electrochemically generated superoxide to rapidly dechlorinate organic compounds such as the polychlorinated biphenyls, trihalomethanes, chlorinated phenols, benzoic acids, and chlorinated polynuclear aromatic hydrocarbons that are found in wastewater. A novel compact electrolytic cell will be utilized for generation of the superoxide used to dechlorinate the organic compounds. After dechlorination, the resultant products are expected to be more amenable to biochemical degradation than they were previously utilizing fixed-film and suspended culture, bio-oxidation wastewater treatment processes. The proposal leading to this project was submitted in response to NSF 88-8, Program Solicitation for Small Business Innovation Research. The contamination of ground and surface waters by organic compounds that are the target of this research is a matter of great National concern. It is imperative that technologies be developed that are responsive to the need to remove organic pollutants from water and wastewater as well as to prepare substances that are not readily biodegradable for treatment by passage through biotreatment processes.

该项目的目标是确定使用电化学产生的超氧化物来快速脱氯有机化合物的可行性，这些有机化合物包括废水中发现的多氯联苯、三卤代甲烷、氯化苯酚、苯甲酸和氯化多环芳香烃。一种新型的紧凑型电解槽将用于产生用于脱氯有机化合物的超氧化物。在脱氯后，所产生的产品预计将比以前使用固定膜和悬浮培养、生物氧化废水处理工艺更易于生化降解。导致该项目的提案是为响应NSF 88-8《小型企业创新研究计划征集》而提交的。这项研究的目标是有机化合物对地下水和地表水的污染，这是一个国家高度关注的问题。必须开发技术，以满足从水和废水中去除有机污染物的需要，并准备不容易生物降解的物质，以便通过生物处理工艺进行处理。
