摘　　要：【目的】佛山市某污水处理厂现状出水“一级B标准”已不能满足《水污染防治行动计划》的排放水质要求,同时为配合佛山市政府规划中轴线北门户中枢建设,降低污水厂运营对周边环境影响,佛山市某地上污水处理厂实施提标改造工程同时改建为全地下式污水处理厂。【方法】污水厂的设计综合处理规模为10万m^(3)/d,出水不仅需满足《城镇污水处理厂污染物排放标准》(GB 18918—2002)修改单(2006年发布)的一级A标准,还必须满足广东省地方标准《广东省水污染物排放限值》(DB44/26—2001)和《汾江河流域水污染排放标准》(DB44/1366—2014)中较为严格的标准,另外氨氮需满足《地表水环境质量标准》(GB 3838—2002)Ⅳ类水标准的1.5 mg/L,并预留出水提标至Ⅳ类水标准的地下设施空间,水处理工艺采用“预处理+复合式厌氧/缺氧/好氧(AAO)生化工艺-移动床生物膜反应器(MBBR)+磁混凝高效沉淀池+紫外接触消毒渠(辅以次氯酸钠)”,除臭工艺采用“生物除臭+离子除臭+全过程根源除臭”并首次引入智慧污水厂应用。【结果】该工程运行至今出水和大气能稳定达标,与原厂相比释放约64000 m^(2)的绿地作为市政公园,实现了土地利用最大化,同时保证工艺顺畅、交通便捷、良好景观视觉效果,智慧污水厂的应用亦提升了行业智能化竞争力。【结论】该工程是佛山市第一间全地下式污水处理厂,为佛山市示范工程,亦评选为“双百跨越”第三期污水处理标杆厂,文章主要介绍其设计方案、工艺流程、设备参数和运营情况等内容,为同类工程提供借鉴。[Objective]The current effluent of a wastewater treatment plant(WWTP)in a certain area of Foshan City cannot meet the discharge water quality requirements of the Action Plan for Prevention and Control of Water Pollution.At the same time,for the purpose of cooperate with the construction of the north gateway center of central axis planned by the Foshan Municipal Government and reduce the impact of the WWTP operation on surrounding environment,a WWTP in a certain area of Foshan City has been upgraded and constructel into a fully underground WWTP.[Methods]The comprehensive treatment capacity of WWTP is 100000 m^(3)/d,and the effluent is subject to the Level A standard of the Pollutant Discharge Standards for Urban Sewage Treatment Plants(GB 18918—2002)amendment list(released in 2006),the stricter of the Guangdong Province local standard Discharge Limits of Water Pollutant(DB44/26—2001)and the Fenjiang River Basin Water Pollution Discharge Standards(DB44/1366—2014).Among them,ammonia nitrogen implements the standard 1.5 mg/L for Level Ⅳ water in the Environmental Quality Standards for Surface Water(GB 3838—2002),and reserves the underground facility space for the water to be upgraded to LevelⅣwater standard.The water treatment process adopts"pretreatment+combined anaerobic/anoxic/aerobic(AAO)biochemical process-moving-bed biofilm reactor(MBBR)+magnetic coagulation high-efficiency sedimentation tank+ultraviolet contact disinfection channel(supplemented with sodium hypochlorite)",the deodorization process adopts"biological deodorization+ion deodorization+whole process root deodorization",and it will introduce the application of smart WWTP for the first time.[Results]Since its operation,the effluent and atmospheric energy of this project have remained stable and meet the standards,compared with the original factory,it has released about 64000 m^(2) of green space as a municipal park,achieving maximum land use while ensuring smooth processes,convenient transportation,and good landscape visual effects,the appl
