摘要
某污水处理厂设计处理能力4万m^3/d,出水水质执行《城镇污水处理厂污染物排放标准》(GB18918-2002)中的一级B标准。通过提标升级,改造原水解池、CASS池,新建调节池及中间提升泵站、混凝沉淀处理单元、反硝化深床滤池强化深度处理,实现《四川省岷江、沱江流域水污染物排放标准》(DB512311-2016)中城镇污水处理厂污染物排放标准。实际运行数据表明,提标升级后的处理水质能够稳定达到对应的排放标准要求。
The design treatment capacity of a sewage treatment plant is 40000 m^3/D,and the quality of the effluent is in accordance with class I B standard in the discharge standard of pollutants for urban sewage treatment plant(GB18918-2002).Through the upgrading of standards,the raw water digestion tank and CASS tank are reconstructed,the new regulating tank and intermediate lifting pump station,coagulation sedimentation treatment unit and denitrification deep bed filter are built to strengthen the advanced treatment,so as to realize the pollutant discharge standard of urban sewage treatment plant in the discharge standard of water pollutants in Minjiang and Tuojiang River Basins of Sichuan Province(DB512311-2016).The actual operation data shows that the treated water quality after upgrading can stably meet the corresponding discharge standard requirements.
