%X 常规水处理工艺通常不能完全将废水中的氯代有机物去除，残留的氯元素仍然具有相当大的环境风险，如何有效地脱除废水中的氯元素是一个亟待解决的难题。本文概述了废水中氯代有机物的来源、种类和危害，并总结了化学还原法去除氯代有机物的发展现状，重点介绍了化学催化剂的性质、种类和投加量以及pH对氯代有机物进行脱氯的影响，并介绍了化学氧化法、物理吸附的工艺的组合集成技术。在此基础上，对未来化学还原技术去除氯代有机物的研究和发展趋势进行了展望。<br />
The conventional water treatment process usually can not completely remove the chlorinated organics in the wastewater, and the residual chlorine still has considerable environmental risk. How to effectively remove the chlorine in the wastewater is an urgent problem to be solved. This paper summarizes the sources, types and hazards of chlorinated organics in wastewater, analyzes the feasibility of removing chlorinated organics by chemical reduction method, focuses on the nature, types and dosage of chemical catalysts and the influences of dechlorination of chlorinated organics by pH, and introduces the combination and integration technology of chemical oxidation method and physical adsorption process. Thirdly, the future research and development trend of chemical reduction technology for the removal of chlorinated organics are prospected.
