摘　　要：目的提高废水中苯酚的去除率。方法分别采用普通Fenton试剂和改性Fenton试剂(纳米Fe3O4/H2O2体系)处理模拟苯酚废水,找出其最佳反应条件,并将两者的处理效果进行对比。结果采用改性Fenton试剂处理苯酚废水,在pH=3时,按照m(COD)∶m(H2O2)=1∶3,n(Fen+)∶n(H2O2)=1∶5投加一定量的纳米Fe3O4和H2O2,搅拌反应60 min,化学需氧量(COD)去除率达到(91.80±1.64)%,而相同条件下普通Fenton试剂的COD去除率为(81.31±1.83)%。结论改性Fenton试剂的处理效果优于普通Fenton试剂的处理效果。Objectives To improve the removal rate of phenol in the wastewater.Methods The ordinary Fenton reagent and the modified Fenton reagent（nano Fe3O4/H2O2 system） were used separately to process simulated phenol wastewater,to find the best reaction parameters and comparing the processing results of the two kinds of reagents.Results The modified Fenton reagent in simulated phenol wastewater can eliminate（91.80 ± 1.64）% COD when nano Fe3O4 and H2O2 were put in the reaction system with the proportion of m（COD）∶m（H2O2）=1∶3,n（Fen＋）∶n（H2O2） =1∶5 and pH=3 after stirring 60 min.But ordinary Fenton reagent’ s COD elimination rate is（81.31±1.83）% in the same condition.Conclusions The treatment effect of modified Fenton reagent is better than ordinary Fenton reagent in processing wastewater containing phenol.
