摘　　要：用Fenton试剂催化氧化法预处理染化厂含苯胺类物质的废水。对影响废水中苯胺类物质去除率的各种因素进行了考察,结果表明,在常温下当废水中苯胺类物质的含量为800mg/L时,在pH为3.5、H2O2和Fe2+用量分别为28mmol/L和2.8mmol/L的条件下,苯胺类物质的去除率可达98.0%,COD去除率达到76%,废水的BOD5/CODCr值由0提高到0.32,显著地提高了废水的可生化性。Anilinecontaining dye wastewater was treated with Fenton's reagent oxidation method. Some factors which influence the removal rate of anilinecontaining were investigated. When pH is 3.5, the concentrations of H2O2 and Fe2＋ are 28mmol/L and 2.8mmol/L respectively in wastewater, the experimental result indicated that the removal rate of aniline can reach 98% and the removal rate of CODCr is 76% under the conditions of room temperature, the raw wastewater aniline 800mg/L , and the ratio of BOD5/CODCr can reach 0.32 after treatment. The effluent can be easily treated by conventional biochemical method.
