摘要
介绍了漕桥污水厂提标改造工程的设计特点。为确保除磷脱氮的效果,通过计算,对现有SBR池重新分隔,将SBR工艺改造成A2/O工艺,同时增加了三级深度处理单元;最后采用紫外线消毒,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。
The design features of upgrading and reconstruction project of Caoqiao WWTP were in- troduced. To ensure the phosphorus and nitrogen removal efficiency, through calculating, the existing SBR tank was redivided, SBR process was transformed into A2/O process, and the tertiary treatment unit was added. The effluent was disinfected with ultraviolet radiation. The effluent quality met the first level A criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant （GB 18918 - 2002）.
