针对某化工园区爆炸事故中高苯胺类、高CODCr污染河段水体,提出Fenton氧化法进行预处理,在单因素试验的基础上进行正交试验,研究了初始pH值、(H2O2)/(Fe2+)摩尔比、H2O2与Fe2+投加量及反应时间对受污染水体处理效果的影响.试验结果表明,当反应时间为60 min、初始pH值为5、(H2O2)/(Fe2+)摩尔比为8∶1、投加量为(CODCr)/(H2O2)质量比1∶2时,处理效果最佳,出水苯胺类未检出,CODCr可降至119 mg/L,去除率达79.6％.根据试验结果指导现场工程应急处置的实施,运行后出水苯胺类浓度可降至0.31～0.77 mg/L,CODCr降至235～301 mg/L,达到园区原有污水处理系统进水水质要求.

Fenton oxidation method was proposed to preprocess the part of the polluted river water with high aniline compounds and high CODCrin an explosion accident of a chemical industrial park.Orthogonal experiment was studied on the basis of single factor experiments.And then the treatment effects of initial pH,(H2 O2)/(Fe^2+)molar ratio,H2 O2 and Fe^2+dosages and reaction time on polluted water were studied.The experimental results show that the treatment effect was best when the reaction time was 60 min,initial pH was 5,the(H2 O2)/(Fe^2+)molar ratio was 8:1,and the dosage of H2 O2 was(CODCr)/(H2 O2...
