摘　　要：以长春市石碑岭垃圾填埋场渗滤液为研究对象,采用混凝-生物接触氧化-电絮凝组合工艺处理垃圾渗滤液,PFS混凝预处理渗滤液最佳运行条件时投药量为0.375g/L;搅拌方式为250r/min;pH值为6;沉降时间为120min,COD去除率可达35.02%。生物接触氧化-电絮凝工艺适于处理COD<5000 mg/L的渗滤液,COD去除去除率可达89.91%,平均BOD5去除率可达91.25%,NH4+-N去除率最高可达86.13%,出水水质可达到国家污水二级排放标准。The coagulation-biological contact oxidation-electric flocculation process was used to treat the landfill leachate from Shibeiling landfill site in Changchun city. The best running conditions of using PFS to pretreat landfill leachate were as follows： quantity of reagent was 0.375 g·L^-1; stirring speed was 250 r·min^-1;pH was 6;settling time was 120 min, the removal rate of COD reached 35.2%.The biological contact bxidation-electric flocculation process was suitable for treating landfill leachate with COD〈 5000 mg·L^-1, the removal efficiency of COD was up to 89.91%,the average removal rate of BOD5 could be up to 91.25%, the best removal efficiency of NH4＋-N was 86.13%, The effluent water quality can meet the national sewage secondary emission standard.
