摘　　要：针对含高浓度COD_(Cr)和氨氮的城市生活垃圾填埋场渗沥液及当地严格的排放限值要求,采用两级A/O-MBR+超滤+两级RO工艺处理渗沥液。经3年多的成功运行表明,该工艺对渗沥液的COD_(Cr)和氨氮的平均去除率分别维持在99.8%和99.9%左右,排水满足GB 16889—2008《生活垃圾填埋场污染控制标准》表3的特别排放限值要求。According to the characteristics of municipal solid waste landfill leachate which contains high concentration of CODCr and ammonia nitrogen,and the strict local discharge emission limits,the combined process of two stage A/O-MBR+ultrafiltration+two stage RO process was adopted.Aftrer more than 3 years of successful running,it could be seen that,the average removal rates of CODCr and ammonia nitrogen by the said process were maintained at about 99.8%and 99.9%respectively,the effluent water quality met the special emission limit requirements of table 3 in GB 16889-2008 Standard for pollution Control on the Landfill Site of Municipal Solid Waste.
