摘　　要：某污水处理厂二期工程设计规模为5×10^(4)m^(3)/d。设计采用多模式生物反应池,可按照A-A^(2)/O、倒置A^(2)/O、Bardenpho、侧流硝化和侧流污泥水解等多种模式运行。实际运行结果表明,在未投加碳源和化学药剂的情况下,该工程出水水质可以达到《城镇污水处理厂污染物排放标准》(GB18918—2002)的一级A标准,后续还有进一步提升的空间。The design scale of the second phase project of a wastewater treatment plant(WWTP)is 5×10^(4) m^(3)/d.A multi-mode biological reaction tank is adopted in the design and can operate according to various modes such as A-A^(2)/O,inverted A^(2)/O,Bardenpho,side-stream nitrification,side-stream sludge hydrolysis and etc.The actual operation results show that the effluent quality of the project can meet the first level A criteria of the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918-2002)without adding carbon source and chemical agents,and could be better for further improvement.
