摘要
某污水处理厂设计规模为10万m^3/d,采用水解酸化-改良AAO-二沉-磁混凝沉淀-滤布滤池-紫外消毒处理工艺,介绍了工程设计和运行情况。工程运行结果表明,出水COD、氨氮、总氮和总磷可达到DB 32/1072—2018《太湖地区城镇污水处理厂及重点工业行业主要水污染物排放限值》中表1标准,BOD5和SS可达到GB18918—2002《城镇污水处理厂污染物排放标准》一级A标准。
A sewage treatment plant with design scale of 100000 m^3/d adopted hydrolytic acidification-modified AAO-secondary sedimentation tank-magnetic coagulation sedimentation-fiber disc filter-ultraviolet disinfection as its sewage treatment process,the design and running condition of the project were introduced.The operation results showed that,the concentrations of COD,ammonia nitrogen,total nitrogen and total phosphorous in the effluent water met the requirement of grade 1 level A in DB 32/1072—2018 Discharge standard of main water pollutants for municipal wastewater treatment plant&key industries of Taihu area;the concentrations of BOD5 and SS met the requirement of GB 18918—2002 Discharge standard of pollutants for municipal wastewater treatment plant.
