摘　　要：采用光助-Fenton处理均苯四甲酸二酐生产废水。以废水的TOC去除率为指标,通过单因素试验和正交试验,对影响光助-Fenton的因素进行分析。结果表明:室温下,在反应初始pH=3.5,[H2O2]=12mmol/L,[Fe2+]=1.5mmol/L,反应时间为80min,光源为500W汞灯的条件下,TOC的去除率NN达到76%。The wastewater treatment in pyromeUitic dianhydride production by photo-Fenton was studied. With the removal rote of TOC as criterion, factors for photo-Fenton were analyzed through single factor test and orthogonal test. The results showed that： using 50Ow mercury, lamp, the initial pH =3.5, [H2O2]= 12rmnol/L, [Fe^2＋]= 1.5mmol/L respectively, the reaction time was 80 rnin trader room temperature, removal rate of TOG reached 76%.
