摘　　要：环氧氯丙烷废水毒性强、生物降解性差,不适合用一般的生物方法处理,提出Fenton试剂氧化处理的方法。实验探索了Fenton试剂反应的影响因素以及条件,发现当废水初始pH为3,H_2O_2的投加量是1.92 g/L,ρ(Fe^(2+))=1.60 g/L,即m(H_2O_2):m(Fe^(2+))=1.2,Fe^(2+)等量分两次投加,总反应时间为1 h时,COD去除率可达89.44%。药剂分次投加比一次投加对处理效果有很大的提高。The wastewater containing epiehlorohydrin is high toxic and hard to be biodegraded,which is not fit for biological treatment. The oxidation process of Fenton reagent was put forward. The experiment explored the affecting factors and conditions of Fenton reagent. It was found that when pH was 3,H2O2 dosage was 1.92 g/L,Fe^2＋ dosage was 1.60 g/L,m（H2O2） ： m（Fe^2＋）was 1.2,Fe^2＋ was added twice by same dosage, and total reaction time was 1 hour, the removal rate of COD reached 89.44 %. The treatment effect was improved greatly by fractionated adding reagents than once adding reagents.
