摘　　要：针对江西某生活垃圾焚烧厂渗滤液,设计系统处理规模为220 m^(3)/d,该渗滤液处理系统采用预处理+调节池+UASB+中沉池+A/O+外置管式UF+纳滤+反渗透,浓缩液采用DTRO深度处理的主体工艺,出水以《城市污水再生利用工业用水水质》(GB/T 19923-2005)中表1敞开式循环冷却水系统补充水用水为标准。从渗滤液处理系统工艺、重点设备、构筑物的设计参数来阐述,项目运行结果表明:出水指标COD、BOD_(5)、NH_(3)-N、SS去除率均优于设计指标,项目稳定运行半年来,污水处理结果优于设计需求。For a domestic waste incineration power plant in Jiangxi designed a set of leachate treatment system,the system treatment scale of 220 m^(3)/d,the leachate treatment system using pretreatment+regulation pool+UASB+sedimentation pool+A/O+external tubular UF+nanofiltration+reverse osmosis,the concentrate using DTRO deep treatment of the main process,the effluent water quality to meet the"urban sewage recycling industrial water quality"(GB/T19923-2005)in table 1 open circulating cooling water system supplement water standards.This paper mainly elaborates the process flow,key equipment and design parameters of the structure of the leachate treatment system,and the project operation results show that the COD,BOD_(5),NH_(3)-N and SS removal rates of the effluent index are more than the design parameter,and the sewage treatment results are better than the design requirements in the stable operation of the project for half a year.
