摘　　要：成都市固体废弃物卫生处置场渗滤液处理扩容工程于2013年建成投入运行,工程规模为1 000 m^3/d,目前已稳定运行2年,出水水质执行《生活垃圾填埋场污染控制标准》(GB16889—2008)表2标准。渗滤液处理采用"外置式膜生物反应器+纳滤"工艺,纳滤浓缩液采用"混凝沉淀+臭氧氧化"工艺,浓缩液处理后出水与纳滤出水混合后达标排放。he leachate treatment expansion project in Uhengou sonu waste ~,~ and put into operation in 2013. The capacity of the treatment project was 1 000 m3/d. At the present time, it has operated stably for more than two years. The effluent quality should meet the requirements in the table 2 of the Standard for Pollution Control on the Landfill Site for Domestic Waste （ GB 16889 - 2008）. The leachate treatment process used external membrane bioreaetor and nanofiltration. The treat- ment process of nanofiltration concentrate used coagulation sedimentation and ozone oxidation. The trea- ted concentrate was mixed with nanofihration effluent, and the mixture could meet the discharge stand- ard.
