摘　　要：南方某园区受污染地表水存在化学需氧量(Chemical Oxygen Demand,COD)和总氮超标等问题,对下游城市河道水环境质量造成影响。结合受污染水质情况,工程采用改进型厌氧-缺氧-好氧(Anaerobic-Anoxic-Oxic,A^(2)O)与膜生物反应器(Membrane Bio-Reactor,MBR)相结合处理工艺,强化脱氮和难降解有机物处理,出水指标稳定达到《地表水环境质量标准》(GB 3838—2002)Ⅳ类标准,详细介绍了该组合工艺的处理流程、主要构筑物及配套设备设计参数,为修复受损水体工程提供参考。The polluted surface water in a certain park in the south has problems such as excessive Chemical Oxygen Demand(COD)and total nitrogen,which have an impact on the water environment quality of downstream urban rivers.Based on the polluted water quality situation,the project adopts an improved Anaerobic-Anoxic-Oxic(A^(2)O)and Membrane Bio-Reactor(MBR)combined treatment process to enhance denitrification and difficult to degrade organic matter treatment.The effluent indicators are stable and meet the Class IV standard of the Environmental Quality Standards for Surface Water(GB 3838—2002).The treatment process,main structures,and supporting equipment design parameters of this combined process are introduced in detail,providing reference for the restoration of damaged water projects.
