摘　　要：针对垃圾填埋场渗滤液处理厂工程现状,分析了原有工艺存在的一些问题,采用“均化池+膜生物反应器(MBR)+纳滤(NF)+反渗透(RO)”组合工艺对垃圾填埋场渗滤液处理系统进行改扩建。膜浓缩液采用“低温蒸发”的技术路线,实现渗滤液全量无害化处理。垃圾渗滤液处理站运行稳定,处理效果好,出水水质满足《生活垃圾填埋场污染控制标准》(GB 16889—2008)中表2要求。In view of the status quo of landfill leachate treatment plant engineering,the problems existing in the process site were analyzed.The combined process of"homogenization pool+membrane bioreacter(MBR)+nanofiltration(NF)+reverse osmosis(RO)"was adopted to upgrade and expand the landfill site.The technology route of"two-stage immersion combustion evaporation"was adopted to realize the harmless treatment of the leachate.The landfill leachate treatment station has stable operation and good treatment effect,and the effluent quality meets the requirements in Table 2 of the Pollution Control Standard for Domestic Waste Landfill(GB 16889—2008).
