摘　　要：河北省某城镇污水处理厂工程的设计规模为4×104 m3/d,污水处理采用奥贝尔氧化沟工艺,在氧化沟前端设置了生物选择池,实际运行表明,该工程除磷脱氮效果较好,出水水质优于《城镇污水处理厂污染物排放标准(》GB 18918—2002)的一级B标准。介绍了污水厂的工艺流程及主要设计参数,并对运行效果进行了分析总结。The design capacity of a municipal sewage treatment plant is 4 × 10^4 m3/d, Orbal oxidation ditch process is used for sewage treatment, and there is a biological selector at the front end of the Orbal oxidation ditch. The actual operation shows that the process has good phosphorus and nitrogen removal effect, and the effluent quality is superior to the first level B criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant （ GB 18918 - 2002）. The process flow and the main design parameters of the municipal sewage treatment plant are introduced, and the operation results are analyzed and summarized.
