摘　　要：根据北京市顺义区水务局的相关要求,因首都机场航空净化站原有污水处理设施不能达标,需升级改造以满足新的排放要求。在不停产施工和不新增构筑物的前提下,提标改造工程的内容包括:投加优势菌种,现有生化系统按A/O方式运行,厌氧池按缺氧池运行,二沉池后增加化学除磷系统(磁絮凝+砂滤工艺)。提标改造工程完成后,出水达到《城镇污水处理厂污染物排放标准》(DB11/890—2012)标准中表1B标准。目前该工程已正常运行12个月,出水水质稳定达标。According to the relevant requirements of the water bureau in Shunyi district,Beijing,the original sewage treatment facilities at capital airport need to be upgraded to meet the new discharge requirements.With the objective of non-stop project and non-add structures,upgrading reconstruction project includes adding superior bacteria in biochemical systems,operating the existing biochemical system in A/O mode,transforming the anaerobic tank into an anoxic tank,adding chemical phosphorus removal system(magnetic flocculation+sand filtration process)after the secondary sedimentation tank.The effluent meets the Class 1B level according to the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(DB 11/890-2012).The project has been running for 12 months producing stable effluent quality compliant with the discharge standard.
