中文摘要：

用混凝-活性碳-过氧化氢组合工艺处理垃圾渗滤液，探讨了不同处理技术的最佳工艺条件和处理效果。结果表明，pH为4．0、投加200mg·L^-1氯化铁、慢速搅拌25min、静置60min时混凝效果最好；而后在室温、pH=3．0、H2O2（质量分数为30％）投加量为5mL·L^-1、活性碳与H2O2的质量比为1：2、反应120min时，COD去除率最好。经混凝．活性炭-H2O2组合工艺处理后，垃圾渗滤液中COD、UV254，UV410和UV436的去除率分别能达到89．44％、82．13％、90．625％和91．35％，其中出水中COD为75．69mg·L^-1，达到GB16889-2008中污染物的排放限值。

英文摘要：

The combination of coagulation-activated carbon/hydrogen peroxide processes was designed for treating the landfill leachate with the high organic content. The optimum treatment conditions were examined through conducting a serious of experiments. After being treated by the coagulation- activated carbon/hydrogen peroxide processes, the removal rates for COD, UV254, UV410 and UV436 levels in the target landfill leachate were improved significantly up to as much as 89.44%, 82.13%, 90.625% and 91.35%, respectively. COD was lowered by 89.44% to 75.69 mg·L^-1. Moreover, the quality of the effluent from the sequential processes treatment meets the emitting concentration limit set by the state standard for municipal solid waste sanitary landfill pollution control （GB 16889- 2008）.
