摘要
针对北方某城市生活垃圾综合处理厂渗滤液的水质特点,采用中温厌氧—MBR(含一级A/O硝化反硝化)—碟管式反渗透(DTRO)工艺进行处理,DTRO浓缩液采用碟管式纳滤(DTNF)+高压级碟管式反渗透(HPRO)+机械式蒸汽再压缩(MVR)工艺进行处理,实现渗滤液的全量化处理。该工程设计处理规模为150 m^3/d,介绍了该工程的工艺流程、处理系统的组成及主要工艺单元设计参数。工程运行结果表明,该工艺运行稳定、处理效果好,出水水质达到《城市污水再生利用城市杂用水水质》(GB/T 18920—2002)中城市绿化和车辆冲洗标准和《城市污水再生利用工业用水水质》(GB/T 19923—2005)中锅炉补给水和工艺与产品用水标准要求。
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 m^3/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 in The Reuse of Urban Recycling Water-Water Quality Standard for Industrial Uses(GB/T 19923-2005).
