摘　　要：某生活垃圾填埋场渗沥液处理站设计规模为850 m^3/d,垃圾填埋场渗沥液处理采用UBF-两级A/O-外置超滤-纳滤-反渗透处理工艺,浓缩液处理采用高压反渗透-蒸发工艺,介绍了渗沥液处理及浓缩液蒸发系统工艺流程、主要处理构筑物和设备设计参数。该项目通过3个月的实际运行数据分析,出水水质达到DB 11/307—2013水污染物综合排放标准排入地表水体B排放标准,经济性较好。The design scale of leachate treatment station in a domestic waste landfill is 850 m3/d.UBF-two stage A/O external ultrafiltration-nanofiltration-reverse osmosis treatment process was adopted for leachate treatment in landfill,and high pressure reverse osmosis-evaporation process was adopted for concentration treatment.The technological process of leachate treatment and concentrate liquid evaporation system and the design parameters of main structures and equipment were introduced.Through the analysis of the actual operation data of the project for three months,the effluent water quality reached discharge standard B for surface water bodies of Integrated Discharge Standard of Water Pollutants(DB 11/307—2013),with good economy.
