摘　　要：垃圾渗滤液水量、水质波动大,污染强度高,处理困难且费用较高,以扬州市某垃圾填埋场渗滤液为研究对象,采用两种微电解-Fenton组合工艺对垃圾渗滤液进行处理。重点考察了反应时间、H2O2投加量和p H值等因素对渗滤液的处理效果。结果表明:(1)微电解-Fenton组合Ⅰ:当p H值为4.0,H2O2投加量为3 m L/L,反应时间为90 min时,COD去除率达到64.3%,氨氮的去除率为65.9%;(2)微电解-Fenton组合Ⅱ:当p H值为4.0,H2O2投加量为1.0 m L/L,反应时间为90 min时,COD去除率达到71.3%,氨氮的去除率为83.9%。The leachate has the disadvantages of the unstable water quantity and quality,high pollution,treatment difficulty and high cost. This paper is based on leachate treatment in Yangzhou Landfill Park,studying the reasonable operating conditions of the iron inner electrolysis and Fenton method and treatment results. The optimal operating parameters are determined by single factor experiment. The connection of Micro-electrolysis and Fenton reagent oxidation are tried and the optimal operating parameters are determined. The experiment result indicates that the optimal operating parameters are as follows：（ 1） The connection of Micro-electrolysis and Fenton oxidation（ Ⅰ） ： the p H value of Micro-electrolysis is 4. 0,the dosage of hydrogen peroxide is 3ml / L,reaction time is 90 minutes,and the COD removal efficiency is 64. 3%;（ 2） The connection of Micro-electrolysis and Fenton oxidation（ Ⅱ） ： the p H value is 4. 0,the dosage of hydrogen peroxide is 3 ml / L,reaction time is 90 min,and the COD removal efficiency is 71. 3%.
