摘　　要：在众多消毒技术中,电化学消毒技术因其具有易操作、自动化程度高及无需化学试剂添加等优势而凸显。系统综述了电化学消毒的3种基本原理,包括电絮凝消毒、电物理场直接消毒和电化学间接消毒。其中电化学间接消毒涉及电生活性氯、H_(2)O_(2)及其诱发的单线态氧^(1)O_(2)、阳极电生·OH、O_(3)等。同时,讨论了3种电化学消毒原理的应用范围和各自的特点。在各种电化学消毒技术中,基于电物理场的局域强电场消毒技术和电生H_(2)O_(2)消毒技术,因无消毒副产物产生而具有广阔市场前景。本综述为深入了解电化学消毒技术机理,明晰其在水处理和公共环境卫生消毒领域的应用,提供了一定理论基础。Among various disinfection technologies,electrochemical disinfection has attracted considerable attention because of its easy operation,high degree of automation,and no external chemical reagent addition.This review systematically summarizes three basic principles of electrochemical disinfection,including electroflocculation disinfection,electrophysical field direct disinfection and electrochemical indirect disinfection.Among them,electrochemical indirect disinfection involves electroactive chlorine,H_(2)O_(2) and the induced singlet oxygen ^(1)O_(2),anode electrogenerated·OH,O_(3),etc.In addition,this article discusses the application scope and respective characteristics of the three electrochemical disinfection principles.Among various electrochemical disinfection technologies,the local strong electric field disinfection technology based on the electric physical field and the electro-generated H_(2)O_(2) disinfection technology are promising due to the absence of disinfection by-products.This review provides a theoretical basis for understanding the mechanism of electrochemical disinfection and clarifying its application in the field of water treatment and public environmental sanitation and disinfection.
