摘　　要：有机氯农药是一类具有生物毒性、环境持久性和生物富集性的有机污染物,电芬顿氧化技术作为电化学氧化技术中最为简单有效的氧化方法,对水中残留的有机氯农药具有良好的去除效果。但受传质效应限制,电芬顿氧化技术降解有机氯农药仍存在电流效率低、氧化剂利用率不足等问题。本文简要论述了复合阴极用于电芬顿体系降解有机氯农药的研究进展,分析了复合阴极电极在电芬顿氧化降解有机氯农药的过程中所起的作用。同时,重点介绍了近年来的研究成果,结构特点、性能、对每种阴极的优点和缺点以及催化剂组分的作用进行了评价与总结,为水中有机氯农药的电化学深度处理提供参考。Organochlorine pesticides are a kind of organic pollutants with biological toxicity,environmental persistence and biological enrichment.Electro-Fenton oxidation technology,as the most simple and effective oxidation method of electrochemical oxidation technology,has a good removal effect on residual organochlorine pesticides in water.However,limited by mass transfer effect,electro-Fenton oxidation technology still has some problems,such as low current efficiency and insufficient utilization rate of oxidant.In this paper,the research progress of composite cathode used in electro-Fenton system to degrade organochlorine pesticides was briefly reviewed,and the roles of composite cathode electrodes in degradation of organochlorine pesticides were analyzed.At the same time,research results,including structural characteristics,performance,and the advantages and disadvantages of each cathodes and the role of catalyst components were evaluated and summarized,so as to provide a reference for the electrochemical advanced treatment of organochlorine pesticides in water.
