三氯乙烯污染的地下水生物修复技术研究进展

Research progress in the Bioremediation Technique of TCE-polluted Groundwater

目前,三氯乙烯(TCE)的大规模使用,已使其成为地下水中分布最广泛的污染物之一。因其在环境中具有持久性,对生物的高毒性作用,而受到了各国的广泛关注。在众多的TCE处理技术中,以生物修复处理技术最经济有效。文章在分析了TCE的性质及其生物降解机理的基础上,结合国内外的相关研究,对微生物修复技术和植物修复技术进行了详细论述,并对微生物修复技术和植物修复技术进行综合分析,指出两种技术相结合的方法可以更有效地去除被污染的地下水中的TCE。

Nowadays trichloroethylene（TCE） has become one of the most widespread contaminants in groundwater because of its use in a large scale, which has drawn a lot attention of many countries for its persistence in environment and high toxicity to living things. Among those technologies to remove TCE in the polluted groundwater, bioremediation is the most effective and economical one. Based on the analysis of the characteristics of TCE and its biological degradation meehartism, studies on mierobialremediation and phytoremediation of home and abroad is introduced in detail. And after discussion of these two techniques, it is concluded that their combination will be more effective to remove TCE in groundwater than just each of them.
