摘　　要：采用Fenton-混凝法对重庆市垃圾填埋场的垃圾渗滤液进行预处理。通过响应面优化设计Fenton氧化处理垃圾渗滤液工艺,建立Box-Behnken数学模型,考察了pH、H_(2)O_(2)投加量和FeSO_(4)·7H_(2)O投加量对垃圾渗滤液化学需氧量(COD)的影响。结果表明:在pH、H_(2)O_(2)投加量和FeSO4·7H_(2)O投加量分别为3.2、1.1%、0.4%时,Fenton法预处理垃圾渗滤液的最佳COD去除率为59.06%。In this paper,treatment of the landfill leachate from Chongqing landfill by Fenton process was studied.The response surface optimization was designed the process of treating landfill leachate with Fenton oxidation,and a box-Behnken mathematical model was studied,and the effects of pH,H2O2 and FeSO_(4)•7H_(2)O on chemical oxygen demand(COD)of landfill Leachate were investigated.The results showed that the optimal COD removal rate of Fenton processing method was 59.06%,which achieved with the pH,H2O2 dosage and FeSO4·7H2O dosages were 3.2,1.1%,0.4%,respectively.
