摘　　要：二苯胺 (DPA)是一种用量很大的化工原料 ,因此本实验使用Fenton试剂对二苯胺废水进行处理 .通过考察反应时间、双氧水用量、硫酸亚铁用量、pH以及反应温度对二苯胺废水TOC去除率的影响 ,同时应用正交实验设计确定Fenton试剂处理二苯胺废水的最佳操作条件 .结果表明 ,随着反应时间的延长 ,TOC的去除率增大 ,最佳反应时间为 30min ,之后趋于平衡 ;当双氧水 (30 % )用量为 6 0mL/L、FeSO4用量为 4 0 0mg/L、pH为 3、反应温度 4 5℃时去除率最高 ,达到 93.4 4 % .Diphenylamine(DPA) is a kind of material applied in chemical engineering widely. Fenton reagent was employed to treat DPA wastewater in this experiment. The effect of reaction time, H_2O_2 dosage, FeSO_4 dosage, pH and temperature on TOC removal efficiency of the wastewater were investigated. The optimum condition was determined via orthogonal experiment. The results show that the removal efficiency of TOC increases with the rising of reaction time and H_2O_2 dosage. The optimum reaction time is 30min and H_2O_2 dosage is 60 mL/L. The other optimum reaction conditions that FeSO_4 dosage is at 400 mg/L, pH is at 3 and the reaction temperature is at 45℃ can reach the best removal efficiency of TOC as 93.44%.
