北京六里屯垃圾渗沥液处理工艺及去除效果分析

摘要

We studied the technique used to treat leachate in Beijing Haidian Liulitun Waste Landfill Site and its treatment effect,including the comparison and analysis for the treatment effect of COD and nitrogen ammonia in different stages,such as UASB,A/O,MB,nanofiltration,etc.The result showed that this technique can stably and effectively reduce COD and nitrogen ammonia in leachate,and economically and effectively meet the requirements for leachate treatment,with the inlet COD and nitrogen ammonia are 2 400～35 150 mg/L and 1 365～2 586 mg/L,respectively.%研究了北京市海淀区六里屯垃圾填埋场的垃圾渗沥液处理的工艺及其处理效果,对UASB、A/O、MBR、纳滤等工段的COD和氨氮的去除效果进行比较与分析.结果表明:当进水COD浓度为2 400～35 150 mg/L和氨氮浓度为1 365～2 586 mg/L时,此组合工艺可稳定高效地去除垃圾渗沥液中的COD与氨氮,且能满足经济、高效地处理垃圾渗沥液的要求.
