污水泵站泵前污水截流井水力模型试验研究

Studies on Hydraulic Modeling for Intercepting Well before Sewage Pumping Station

对合流污水泵站泵前截流井进行了水力模型试验研究 ,并提出了设计改进措施 ,比较分析两种截流井方案在各种截流量、开启度等工况时的水头损失、流态特征 ,研究雨水泵启用对截流量的影响 ,以及截流井对上游排水设施的影响。根据研究成果 ,对设计及日后运行管理提出了合理建议。

Hydraulic modeling for the intercepting well in front of the combined sewage pumping station is performed, with modifications to the design. Two proposed wells are compared in head loss and flow and in the impact of actuating the storm water pump on the intercepting flow and the impact of the well on drainage facilities upstream. With the results, proposals are made for the design and operation management.
