摘要
无锡太湖国家旅游度假区污水处理厂提标改造工程实施规模为1.25×104m3/d,采用强化CAST生物脱氮、机械微过滤(盘片过滤)工艺,改造后处理出水达到了《城镇污水处理厂污染物排放标准》(GB 18918—2002)的一级A标准。介绍了该工程的工艺流程、设计参数及技术特点。
The design capacity for upgrading and reconstruction of the wastewater treatment plant in Wuxi Taihu Lake National Tourism Vacation Zone is 1.25×10^4m^3/d. The enhanced CAST for biological nitrogen removal and mechanical micro-filtration by disc are used. After the reconstruction, the effluent quality can reach the first level A criteria specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant （GB 18918 -2002）. The process flow, design parameters and technical characteristics of this project are introduced.
