根据上海市合流污水治理第二期工程SA泵站水力模型试验,分析城市污水泵站普遍存在的前池不良进水流态现象及其对水泵性能、前池淤积的影响,提出改善前池流态、减少淤积的措施.试验表明,改进后的前池使流态得到明显改善,水泵机组效率明显提高,并可有效减少前池淤积. According to the hydraulic model test of the SA pumping station of the second phase of the combined wastewater treatment project in Shanghai, the phenomenon of poor inlet flow in the front pool and its effect on the performance of the pump and the pooling of the fore-pool in the urban sewage pumping station were analyzed. , Measures to reduce siltation. Tests have shown that the improved front tank makes the flow state significantly improved, the efficiency of the pump unit is significantly improved, and the siltation in the front pool can be effectively reduced.
