硫酸盐还原作用对氯代有机物还原脱氯影响的研究进展

A Review on the Effect of Sulfate Reduction on the Reductive Dechlorination of Chlorinated Organic Compounds

脱氯是氯代有机物降解的关键步骤,还原脱氯是其模式之一。硫酸盐还原是典型的还原过程,在有机污染物厌氧降解中扮演重要角色,但其对氯代有机物还原脱氯的影响及机制尚未形成定论。本文综述了硫酸盐还原作用对氯代有机物还原脱氯的影响情况、影响因素及可能的影响机制,提出了今后值得深入研究的方向。

Dechlorination is a key step to degradate chlorinated organic compounds,and reductive dechlorination is one of the patterns.As a typical reductive process,sulfate reduction plays an important role in the anaerobic degradation of organic pollutants,while the effects and mechanisms of which on the reductive dechlorination of chlorinated organic compounds has not been defined yet.In this paper,the effects and probable mechanisms of sulfate reduction on the reductive dechlorination of chlorinated organic compounds were reviewed and discussed,and further researches were prospected.
