摘　　要：电Fenton法因其能通过原位生成的H_(2)O_(2)与Fe^(2+)反应产生强氧化性羟基自由基(·OH),可以有效降解废水中的各类有机污染物。本文介绍了电Fenton法在传统Fenton法基础之上的改进和反应原理,重点综述了电Fenton法在初始pH、曝气量、溶液导电性和电流密度方面的影响,对电Fenton法能高效清洁地处理难降解有机废水进行了展望,未来可通过进一步研究新型阴极材料和联合其他工艺共同作用提高降解率。The electric Fenton method can effectively degrade various organic pollutants in wastewater due to its ability to generate strong oxidizing hydroxyl radicals(·OH) through the reaction between in-situ generated H_2O_(2) and Fe~(2+).This article introduced the improvement and reaction principle of the electric Fenton method on the basis of the traditional Fenton method,focusing on the impact of the electric Fenton method on initial pH,aeration rate,solution conductivity,and current density.It looks forward to the efficient and clean treatment of refractory organic wastewater by the electric Fenton method.In the future,the degradation rate can be improved through further research on new cathode materials and the combined effect of other processes.
