【摘要】 由于城市污水中含有大量固体悬浮颗粒 ,城市污水泵站前池普遍存在淤积问题 ,给泵站运行、管理带来不便 ,有必要通过水力模型浑水试验探求前池防淤措施 .结合上海市污水治理 2期工程南线 #A泵站水力模型试验研究 ,利用浑水试验 ,对城市污水泵站前池淤积问题进行一定的探讨 ,通过对不同的改进措施下前池淤积状况的分析比较 ,提出了在原设计前池中设置 45°导流板的最佳防淤措施更多还原

【Abstract】 As suspended solid particles being carried in city sewerage, sediment deposition generally existing in the forebays of city sewage pumping stations often causes problems for operation. It is necessary to search for measures to prevent the sedimentation in the forebay. Related to the research on the hydraulic model tests for the south main drain #A pumping station of the Second Shanghai Sewerage Project and made use of silt-laden water test, the problems of sedimentation in the forebay in a city sewage pumping station are discussed, and the best improvement measure using 45° barrier plate in the forebay of the preliminary design to prevent sedimentation is put forward in this paper.更多还原
