摘　　要：上海市污水治理二期工程是我国最大的污水治理工程,此项工程的目的是为了减轻黄浦江上游水质污染。南线A号污水泵站是上海市污水治理二期工程之一。本文通过水力模型试验,发现原设计泵站流态较为恶劣、水泵效率下降和泥沙沉积严重。在原设计基础上以增加八字形导流墩、压水板、挡水板作为改进措施进行多种工况试验,均可获得较好的流态及流速分布,水泵效率也有明显的提高。Schanghai Municipal Wastewater Treatment Project II is the largest sewage treatment works in our country. The purpose of this project is to reduce water pollution in the upper roaches of Huangpu River. South A sewage pumping station is one of the Shanghai Municipal Wastewatel Treatment Project Ⅱ . By hydranlic model test a poor flow state was found declining of pump＇s efficiency and heavily depositing. In the basement of original design, the guides piers, depressed plate and elimination were added to improve working conditions and tests. Finally, the better flow state and velocity distribution are got and the pump efficiency have been significantly improved.
