摘　　要：针对具体的城镇生活污水处理工程,构建了改良型氧化沟(厌氧/立体循环式氧化沟/缺氧,A/VLR/A)+膜生物反应器(MBR)组合工艺,探讨了北方寒冷地区城镇污水厂设计实践经验。连续运行结果表明,在调试后的工艺条件下,改良型氧化沟+MBR组合工艺对主要污染物具有良好的去除效果,出水水质达到城镇污水处理厂污染物排放标准(GB 18918-2002)的一级A标准,满足中水回用标准,全部用作工业循环用水。Aimed at municipal wastewater, the combined technologies of the modified oxidation ditch （Anaerobic/Vertical Loop Reactor/Anoxic, A/VLR/A） and membrane bio-reactors （MBR） were selected as the key process for the investigation of design practice of a municipal wastewater treatment plant in the frore area. The results showed that A/VLR/A＋MBR could achieve high efficiency of main pollutants removal under the optimal operation condition. It was found that almost all effluents met the 1-A criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant （GB 18918-2002）, and the effluent was reused as industrial circulating water.
