摘　　要：杭州市七格污水处理厂四期工程规模为30×10^(4) m^(3)/d,针对城市土地资源愈发稀缺、居民对环境要求日益增高等问题,采用双层加盖的半地埋布置形式,顶部为生态主题景观公园。污水处理采用具有脱氮除磷功能的“A+AAO生物处理+反硝化深床滤池+紫外线消毒”工艺,出水水质稳定达到并优于一级A排放标准。该工程具有环境友好、土地集约、资源利用、工艺运行灵活等优点,是杭州市首座半地埋式污水处理厂,相比七格前三期地上式污水处理厂,其单位处理水量占地面积减少31%。The Qige sewage treatment plant phase IV project in Hangzhou has a daily capacity of 30×10^(4) m^(3)/d.To address challenges such as the urban land scarcity and heightened environmental expectations from residents,the facility is designed as a double‑storey semi‑underground structure with a covered top storey featuring an ecological themed landscape park.The sewage treatment process includes an A+AAO biological tank,denitrification deep bed filter,ultraviolet disinfection,ensuring nitrogen and phosphorus removal.The treated effluent quality exceeds the grade A standard specified in the discharge regulations.The project offers several advantages including environmental friendliness,land intensification,resource utilization,and flexible process operation.It marks Hangzhou’s first semi‑underground sewage treatment plant.Moreover,compared to the first three phases of the Qige sewage treatment plant aboveground,the area required per unit of treated sewage has been reduced by 31%.
