摘　　要：某全地埋式污水处理厂工程规模为20×104m3/d,采用A2/O工艺处理深圳布吉城镇河道污水,出水COD、SS、TN、TP及NH3-N等指标均可达到《城镇污水处理厂污染物排放标准》(GB 18918—2002)的一级A标准。该地埋式污水厂进水口设计为河道自流进水,采用了新型的双层沉淀池、生物除臭等设计理念,节省占地,运行效果好。The engineering application of a type of whole underground wastewater treatment plant was introduced. The design capacity was 20 × 10^4 m3/d. The improved A2/O process was used to treat Shenzhen Buji River wastewater. The effluent indicators including COD, SS, TN, TP and NH3 - N could meet the first level A criteria specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant （GB 18918 -2002）. The inlet of the wastewater treatment plant was designed for gravity flow. The new double layer horizontal flow sedimentation tank and biological deodorization were designed. The land was saved, and the operation effect was good.
