摘要
安徽省某污水厂一、二期工程出水水质分别达到了《城镇污水处理厂污染物排放标准》(GB 18918—2002)的二级和一级B标准,为实现节能减排,拟建深度处理工程,出水水质需达到一级A标准,并回用作火电厂循环用水的补充水。深度处理采用曝气生物滤池和深床反硝化滤池工艺,详述了工艺流程选择和深度处理构筑物的设计参数。
The effluent quality of the first-stage and second-stage projects of a WWTP in Anhui Province respectively met the class II and I -B criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant （GB 18918 -2002）. In order to achieve the energy saving and emission reduction, the advanced treatment project is planned to be built. The effluent quality would meet the class I -A criteria, and the effluent would be reused as make-up water for cooling water of thermal power plant. The biological aerated filter and deep-bed denitrification filter were designed to be used in the advanced treatment. Details of the process and the design parameters of the advanced treatment structures were expounded.
