水资源中氯代烃污染物的去除方法

Elimination of chlorinated organic compounds in water

随着工业化的发展 ,氯代有机溶剂使用越来越广泛 ,并且难于去除。在 2 0世纪 90年代初期 ,人们就已认识到用Fe0 恢复污染的地下水的潜力。国外正在研究和使用的几种还原挥发性氯代烃的还原反应介质 ,尤其要提到的是双金属反应系统 ,反应速度快 ,而且脱Cl中间难降解产物少 ,目前国外也只停留在实验室研究阶段 ,个别做了地上反应器的验证实验 ,它的脱Cl机理。

Volatile chlorinated organic compounds are used extensively more and more as the develop of industry and difficult to be eliminated.People had realized the potential of zero valence iron to eliminate the pollution in the underwater in 1990s.Some reductive medium of reductive volatile chlorinated organic compounds are using in abroad,especially bimetallic systems have quick reaction speed and less difficult degradated elements.But it is only in the test and verify stage, the dechlorination principle,dull medium and dechlorination completely is in the problems.
