摘　　要：通过正交试验得出影响Fenton反应主要影响因素是初始pH值和初始Fe2+浓度,其次是H2O2浓度。探讨了Fenton反应中各影响因素的作用机理,并确定了反应的最佳条件:pH=2,[Fe2+]=0.205mol/L,[H2O2]=2.05mol/L,[KH2PO4]=40.0mmol/L。在最佳反应条件下,Fenton氧化后的废水CODCr值为750mg/L。将Fenton反应氧化后的污水经过好氧生物进行处理,处理后的废水达到GB1918—2002二级排放标准。It was proved that the main factors affecting the Fenton reaction was the initial pH and initial Fe^2＋ concentration,followed by the concentration of H2O2,which was determined by orthogonal tests.The mechanisms of the factors were discussed in the Fenton reaction and the optimum reaction conditions were obtained as following： pH=2,=0.205 mol/L,= 2.05 mol/L, = 40.0 mmol/L.Under the optimum reaction conditions,CODCr was dropped to 750 mg/L after Fenton process.The wastewater that had been pretreated by the Fenton process was purified in biological process in the further process,and the treated wastewatercould be discharged safely according to the level 2 emission standard of GB 1918—2002.
