泗塘污水处理厂功能调整的方案设计

Scheme Design for Functional Adjustment of Sitang Sewage Treatment Plant

为解决泗塘污水处理厂周边河道黑臭问题,在短时间内无法全面完成雨污混接改造的条件下,对利用现状泗塘厂进行功能调整开展研究。改造厂内二沉池及生物池等构筑物为调蓄池,调蓄容积12 370 m^3,新建初期雨水提升泵站1座,规模为5 m^3/s,新建初期雨水调蓄管道φ2 700 mm,长约1.6 km,调蓄容积9 156 m^3。

To solve the problem of black and odor in rivers around Sitang Sewage Treatment Plant,the function adjustment of Sitang Sewage Treatment Plant is studied under the condition that the transformation of mixed rain and sewage cannot be completed in a short time.The secondary sedimentation tank and biological pond in the plant are reconstructed as storage tank with a storage capacity of12370m3.A new initial rainwater lifting pumping station with a scale of5m3/s is built.The initial rainwater storage pipeline isφ2700mm,about1.6km in length and9156m3in volume.
