摘要
综述了包括物理法、化学法、生物法在内的对地下水中三氯乙烯(TCE)污染修复的研究现状。从经济有效性和降解产物无害化角度,指出以脱氯菌(Dehalococcoides spp.)降解TCE是目前最为安全的修复方法之一。为进一步提高其处理效率,综合考虑脱氯菌所需合适的电子供体、适宜p H和氧化还原电位条件等方面,提出了以天然矿物电气石协同脱氯菌降解地下水中三氯乙烯的研究思路。
The research status quo of the remediation of trichloroethylene（TCE） pollution in groundwater,including physical,chemical and biological methods is summarized. In terms of economic efficiency and degraded product harmlessness,it is pointed out that using dechlorinating bacteria（Dehalococcoides spp.） for the degradation of TCE is one of the safest ways of its remediation. In order to further improve the treatment efficiency,and based on an integrated consideration on the appropriate electron donor,optimum p H,a oxidation reduction potential conditions,etc.,the research idea of using tourmaline cooperating with declorination bacteria for the degradation of TCE from groundwater is put forward.
