摘　　要：电解法是利用电能实现氧化还原反应的方法,其应用于消毒通常有电产次氯酸钠消毒剂和电化学消毒2种方式。为深入了解电产次氯酸钠及电化学消毒技术机理,进一步探讨电解法在水处理和公共环境卫生消毒领域的应用,从消毒原理、技术特点、使用方法和消毒应用方面,对电解法制备次氯酸钠与电化学消毒水处理技术进行了介绍与分析,并提出了目前存在的问题和技术发展前景,为该技术的实际应用提供参考。Electrolysis is a method that uses electrical energy to achieve a redox reaction. There are two ways for the application of electrolysis in disinfection, i.e., on-site electrochemical generation of sodium hypochlorite disinfectant and electrochemical disinfection. To deeply understand the mechanism of electrochemical generation of sodium hypochlorite and electrochemical disinfection process, and further discuss the applications of electrolysis in water treatment and public environmental sanitation, the disinfection principle, technical characteristics, usage, and disinfection applications were discussed. The current problems and technical development prospects were also proposed. The present study will provide a reference for the practical applications of electrolysis technology in water treatment.
