上海污水治理二期工程南线A^#泵站浑水模型试验

SILT-LADEN WATER MODEL TEST ON SA PUMPING STATION OF THE SECOND STAGE OF SHANGHAI COMBINED SEWAGE PROJECT

城市污水泵站普遍存在淤积问题，给泵站运行、管理带来不便。结合上海市合流污水治理二期工程南线Ａ＃泵站水力模型试验研究，通过浑水试验，对原设计前池、高位井淤积规律进行了分析，提出降低前池淤积的措施。

Sedimentation generally exhisting in city sewage pumping stations causes problems and inconveniences for operation.Based on silt laden water test and combined with hydraulic model tests for A # pupmping station on the south main drain of the Second Stage of Shanghai Combined Sewage Project,sediment regularities in the pumping well and the high level discharge chamber originally designed are analyzed in this paper,and measures to reduce sediments in the pumping well are also put forward.
