| 摘 要： | 采用间歇反应器和单因子逐一变化法，对影响Fenton氧化处理垃圾滤液效果的主要因素进行了研究和优化．结果发现，在pH值为3、Fe^2＋]0=4mmol／L和Fe^2＋]0：H2O2]0=1：16的最佳条件下，垃圾渗滤液经过4～13h处理，其COD可降至初始值的61％～56％，BOD5／COD值明显增大，滤液的生物可降解性提高；滤液的Fenton氧化过程服从两段一级反应动力学模型．

| Abstract: | The treatment of landfill leachate by Fenton process was investigated. Experiments were conducted in a batch reactor to examine the effects of operating factors including pH,hydrogen peroxide concentration and ferrous ion concentration on chemical oxygen demand(COD) of treated leachate.The optimal reacting conditions were experimentally found to be =4 mmol/L,H_2O_2]/=16 and pH=3 at room temperature.Under these conditions,the initial COD of the leachate was reduced by about 40% within 4 h.The bioavailability of the leachate was improved after Fenton oxidation,as indicated by its BOD_5 /COD ratio to be larger than 0.5.In addition,Fenton oxidation used in this process conforms to two-stage the pseudo-first-order kinetic model. |
