天津经济开发区污水处理厂是开发区的重点环保工程,设计规模为10万t/d,采用SBR工艺,根据开发区总体规划的调整要求,该厂进水泵房要与附近海晶东市政雨、污水泵站合建,形成三站一体的合建泵房,流量分别为1.157m~3/s、11.8m~3/s及0.6m~3/s,为减少占地面积,优化水流条件,工艺采用了纵横及上下分隔的布置形式,使三个泵站形成各自独立的进出水系统,三个进出水系统合建为一个泵房,在天津地区尚属首创,由于工艺布置复杂,纵横及上下交错,因此给结构设计带来一定难度。 天津经济开发区位于天津市东南,东邻渤海湾,地质条件属冲积海积平原,沉积物颗粒较细,
The Tianjin Economic Development Zone sewage treatment plant is a key environmental protection project in the development zone with a design scale of 100,000 t / d. The SBR process is adopted. According to the adjustment requirements of the overall planning of the development zone, , Sewage pumping station construction, the formation of a three-station of the combined building pump, flow were 1.157m ~ 3 / s, 11.8m ~ 3 / s and 0.6m ~ 3 / s, in order to reduce the area, , The process adopts vertical and horizontal and up and down separation of the layout, so that the three pump stations to form their own separate out of the water system, the three out of the water system together into a pump room, is still the first in Tianjin, the process layout is complicated, aspect And staggered up and down, so to the structural design of a certain degree of difficulty. Tianjin Economic Development Zone is located in southeast of Tianjin, east of Bohai Bay, geological conditions are alluvial marine plain, sediment particles smaller,
