摘　　要：通过UNITANK工艺与倒置A2/O工艺对低碳源城市生活污水的中试处理效果、UNITANK工艺与改良型A2/O工艺在南方地区的实际生产运行效果的对比研究表明,UNITANK工艺和A2/O工艺对南方地区低碳源城市生活污水均具有较好的处理效果,出水水质均可达到《城镇污水处理厂污染物排放标准》(GB 18918—2002)的一级A标准。综合考虑,虽然UNITANK工艺的处理效果略逊于A2/O工艺,但其运行维护费用更低、控制更加灵活、运行管理更为简单。因此,新建污水处理厂可优先选择UNITANK工艺。The pilot-scale treatment effects of municipal sewage with low carbon source by the UNITANK process and the reversed A^2/O process were investigated, and the operation efficiencies of the UNITANK process and the improved A^2/O process in southern China were compared. The results showed that both the UNITANK process and the A^2/O process could effectively treat municipal sewage with low carbon source. The effluent quality met the first level A criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant （ GB 18918 - 2002 ）. Taking technical and economic factors into account, a new wastewater treatment plant should adopt the UNITANK process due to its lower operating and maintenance cost, more flexible control and simple operation management despite slightly inferior treatment effect compared to the A^2/O process.
