针对北方某城市糊口垃圾分析处置厂渗滤液的水质特点，采取中温厌氧—MBR（含一级A/O硝化反硝化）—碟管式反渗入（DTRO）工艺进行处置， DTRO浓缩液采取碟管式纳滤（DTNF）+高压级碟管式反渗入（HPRO）+机器式蒸汽再紧缩（MVR）工艺进行处置，实现渗滤液的全量化处置。该项目设想处置范围为150 m3/d，引见了该项目的工艺流程、处置系统的构成和首要工艺单位设想参数。项目运转成果注解，该工艺运转不变、处置结果好,出水水质到达《城市污水再生操纵 城市杂用水水质》（GB/T 18920—2002）中城市绿化和车辆冲刷尺度和《城市污水再生操纵 工业用水水质》（GB/T 19923—2005）中汽锅补给水和工艺与产物用水尺度要求。
According to the water quality characteristics of leachate from a municipal waste comprehensive treatment plant in northern China, a combination process of medium temperature anaerobic-MBR (including first-stage A/O nitrification and denitrification)-disc-tube reverse osmosis (DTRO) process was adopted to treat the leachate. The concentrate of DTRO was treated by combination process of disc-tube nanofiltration (DTNF)+high-pressure disc-tube reverse osmosis (HPRO)+mechanical vapor recompression (MVR).This realized the total quantitative treatment of leachate.The design treatment capacity of the process was 150 m3/d. The process flow, the composition of the process and the design parameters of the main treatment units were introduced. The results of project operation showed that the process ran steadily and had a good treatment performance. The effluent quality reached the standard of urban greening and vehicle flushing in The Reuse of Urban Recycling Water—Water Quality Standard for Urban Miscellaneous Water Consumption(GB/T 18920-2002) and the boiler replenishment water and process and product water inThe Reuse of Urban Recycling Water—Water Quality Standard for Industrial Uses (GB/T 19923-2005).
