摘　　要：采用Fenton试剂处理生化处理后的垃圾渗滤液,探讨了pH、Fe2+、H2O2、反应时间等对CODCr去除效果的影响.结果表明,Fenton氧化法对垃圾渗滤液CODCr去除有较好的效果.Fen ton氧化法的最佳操作条件:pH=7,H2O2投加次数为1,FeSO4·7H2O的投加量为0.1mol/L,H2O2/FeSO4·7H2O投加比为4∶1,反应时间为210min,反应温度为30℃.The landfill leachate after the biological process was treated with Fenton reagent, and the effect of pH,Fe^(2+) , H_2O_2 and reaction time on the result of removal of COD_(Cr) is discussed.The result shows that the effect of removing the landfill leachate COD_(Cr) by Fenton oxidation method is better.The optimum operation conditions of Fenton oxidation method is as follows:when pH is 7,the imput time of H_2O_2 is 1,and when imput amount of FeSO_4·7H_2O is 0.1 mol/L, the imput ratio of H_2O_2 and FeSO_4·7H_2O is 4∶1,the reaction time is 20 minutes and the reaction temperature is 30 ℃.
