Abstract: In this paper，the effects of operating conditions on the Fenton’s oxidation process of landfill leathate were investigated by using statistical methods. Response surface methodology (RSM) was used to investigate the effect of FeSO4•7H2O concentration，H2O2/FeSO4•7H2O and pH on COD removal. The high and low levels of pH values，K2S2O8 concentration and bias potential were 0.01 to 0.02 mol/L，1 to 5mg/L and 2 to 6 respectively. Using the software of Design-Expert 5，a response surface quadratic model in terms of actual factors was obtained based on the experimental data. The optimum FeSO4•7H2O concentration，H2O2/FeSO4•7H2O and pH were found to be 0.013mol/L，4.60，and 4.45 respectively and the highest COD removal efficiency (69.85%) could be achieved.

摘要： 利用统计学的方法对Fenton氧化垃圾渗滤液的影响因素进行了探讨和分析，考察了FeSO4•7H2O投加量，H2O2/FeSO4•7H2O比值和pH值对氧化垃圾渗滤液的影响。在FeSO4•7H2O投加量为0.01～0.02 mol/L、H2O2/FeSO4•7H2O比值1～5和pH值2～6的条件下，分析CODCr的变化。通过使用Design-Expert 5 软件可得到1个二次响应曲面模型，最佳的FeSO4•7H2O投加量为0.013mol/L、H2O2/FeSO4•7H2O比值4.60和pH值4.45，从而CODCr的去除率也达到最大（69.85%）。
