中文摘要：

三氯乙烯（TCE）是一种挥发性的有机溶剂,具有较强的环境毒性,对人体有很大危害,被列为＂优先控制化合物＂及＂疑似致癌物质＂.近年来,许多研究者采用各类技术对TCE的降解进行了系统研究,并取得一定成效,为TCE环境污染的修复提供了多种方法.本文综述了物理修复、化学修复、植物修复及微生物修复等TCE原位修复方法的原理、效能、优缺点及各方法的影响因素,并展望了今后TCE修复技术的发展趋势.

英文摘要：

Trichloroethylene（TCE） is a volatile organic solvent with strong environmental toxicity.Identified to be seriously harmful to human bodies,it has been classified as ＂priority-controlled compounds＂ and ＂suspected carcinogens＂.Recently,various technologies for TCE degradation have been systematically studied,with successful outcomes.They provide a variety of methods for environmental remediation for TCE pollutions.This paper reviews the mechanism,performance,and Pro/Con of several in situ remediation technologies,listed as physical remediation,chemical remediation,phytoremediation,and microbial remediation.An outlook on developing trend of TCE remediation technologies is also proposed.
