Integrated Electrochemical Degradation and Biodegradation for Treatment of Contaminated Groundwater

0086839 Reardon本研究的目的是提高受污染地下水迁移羽流的原位处理效果。 待开发和协同组合的工程技术是（1）局部氧化还原环境的电化学改变和（2）增强生物降解。 设想的实施需要建设一个羽流拦截区，其中氯化污染物（如全氯乙烯）的降解增强发生地下水穿越该地区。 由于两个原因，预计污染物的销毁会增加。 第一，在插入拦截区上游侧的阴极表面处产生的还原条件将刺激能够使污染物脱氯的细菌群体的发展。 第二，该区下游部分产生的氧化条件，加上污染物的脱氯状态，将导致加速矿化。 这项赠款是根据征求NSF 00-49，新技术的环境。***

0086839 Reardon The objective of this research is to improve the efficacy of the in situ treatment of migrating plumes of contaminated ground water. The engineering technologies to be developed and synergistically combined are (1) electrochemical alteration of the local redox environment and (2) enhanced biodegradation. The envisioned implementation entails constructing a plume-intercept zone in which the augmented degradation of chlorinated pollutants (e.g. perchloroethene) occurs as ground water traverse the zone. The augmented destruction of contaminants is an anticipated outcome for two reasons. First, the reducing conditions generated at the cathodic surfaces inserted in the upstream side of the intercept zone will stimulate the development of bacterial populations that can dechlorinate the pollutants. Second, the oxidizing conditions generated in the down stream section of the zone in conjunction with the dechlorinated state of the pollutants will lead to accelerated mineralization. This grant is made pursuant to Solicitation NSF 00-49, New Technologies for the Environment. ***
