摘　　要：天津双林污水处理厂污水处理规模为4.0×104m3/d,再生水规模为0.5×104m3/d。污水处理采用Carrousel 2000型氧化沟/机械絮凝/斜管沉淀/纤维转盘过滤工艺,再生水处理采用超滤膜/臭氧/消毒工艺。经过几年运行,污水处理厂出水各项指标均优于设计标准,结合天津市发布的污水厂类Ⅳ类水体排放标准,提出本工程进一步提升改造的思路。The treatment capacities of sewage and reclaimed water of Tianjin Shuanglin Sewage Treatment Plant were 4.0×10^4m^3/d and 0.5×10^4m^3/d, respectively. Sewage treatment adopted the combined process of Carrousel 2000 oxidation ditch, mechanical flocculation, inclined tube settling and rotary fibre disk filtration. Reclaimed water treatment adopted the combined process of ultrafiltration membrane, ozone and disinfection. After several years of operation, the effluent indicators of the sewage treatment plant were better than design standards. Taking into account the release of class IV water discharge standards for wastewater treatment plants in Tianjin, the upgrading and reconstruction ideas of this project were proposed.
