Feasibility of Biodegradation of Tetrachlorethylene in Contaminated Aquifers

该项目的目的是研究将电化学过程应用于受卤化有机物质污染的土壤中有害物质就地脱卤化的技术可行性，卤化有机物质是在物质运输过程中因意外泄漏而从危险废物封存地点泄漏或进入地下水的。在这个项目中，卤化有机物质将受到电化学过程的影响，这将导致它们的脱卤化。这将在溶剂存在的情况下进行，如果有效，将使从受它们污染的土壤中去除脱卤素物质在技术上成为可能。一种在土壤中销毁卤化危险废物的方法是可靠的，不允许释放可能的危险废物，不使用活性化学品，其低成本将立即被政府和行业应用于清理受泄漏或泄漏污染的垃圾填埋场和土壤。导致这一阶段I奖的提案是根据NSF 87-8，NSF计划征集，小企业创新研究提交和评估的。

The objective of this project is to investigate the technical feasibility of applying an electrochemical process to the in situ dehalogenation of hazardous substances in soils contaminated by halogenated organic substances that leak from hazardous waste containment sites or enter groundwater as a consequence of accidental spills while substances are in transit. In this project, halogenated organic substances will be subjected to an electrochemical process that will cause their dehalogenation. This will be done in the presence solvents which, if effective, would make it technically possible to remove the dehalogenated substances from soil contaminated by them. A process to destroy halogenated hazardous wastes in soils which is reliable, does not permit release of possibly hazardous wastes, does not use reactive chemicals, and its low cost will have immediate application by both government and industry to clean-up landfills and soils contaminated by leaks or spills. The proposal leading to this Phase I award was submitted and evaluated in accord with NSF 87-8, NSF Program Solicitation, Small Business Innovation Research.
