福田污水处理厂位于深圳市核心区域,设计规模为40×10~4m~3/d。为解决传统A~2/O工艺脱氮除磷效果不佳、能耗较高等问题,生化池采用多段强化脱氮A~2/O工艺,多点进水并同步实施精确曝气系统,进一步强化脱氮除磷效果,在保证处理效果的同时有效降低了能耗。生化池与二沉池组合体采用半地下式结构,顶部加盖覆土作为市政公园。污水厂既有全地下式污水厂的优美环境,又具有地上式污水厂操作管理的便捷。项目建成后生产运行稳定,效果良好,出水水质全面优于《城镇污水处理厂污染物排放标准》(GB 18918—2002)一级A标准。
Futian sewage treatment plant is located in the core area of Shenzhen City, the design scale of 40 × 10 ~ 4m ~ 3 / d. In order to solve the problems of poor efficiency and high energy consumption of conventional A ~ 2 / O process, the biochemical pool adopts multi-stage enhanced denitrification A ~ 2 / O process, water inflow and synchronization of precise aeration system, further Strengthen the effect of nitrogen and phosphorus removal, to ensure that the treatment effect while reducing energy consumption. Biochemical pool and secondary sedimentation tank combination of semi-subterranean structure, top covered with soil as a municipal park. Sewage plant both the underground sewage plant beautiful environment, but also has the convenience of ground-based sewage treatment plant operation and management. After the completion of the project, the production runs steadily and the effect is good. The water quality of the effluent is better than Grade A standard of “Emission Standard of Pollutants for Municipal Wastewater Treatment Plant” (GB 18918-2002).
