【摘要】 对给水厂深度处理中间提升泵房的水泵选型、泵房布置、泵房前调蓄水池设计等进行比选研究,中间提升泵房连接水厂常规处理构筑物和深度处理构筑物,其运行的可靠性直接影响到后续深度处理的稳定运行。比选了3种水泵形式:卧式离心泵、立式混流泵和潜水混流泵,从水泵运行规律适用性、建设成本、日常维护检修便利性等方面考虑,优选潜水混流泵型中间提升泵房。泵房前调蓄水池的容积大小与水厂实际运行诸多因素有关,需合理确定。更多还原

【Abstract】 The water pump selection, pump house layout, and pump house front reservoir design of the advanced treatment intermediate pumping house are studied, which is connected conventional treatment structure and advanced treatment structure in the waterworks. Reliability of its operation directly affects the stable operation of subsequent advanced treatment. In this paper, three types of pumps are selected and compared: horizontal centrifugal pump, vertical mixed flow pump and submersible mixed flow pump. For the aspects of pump operation applicability, construction cost, convenience of routine maintenance and repair, the submersible mixed flow pump is preferred to use in intermediate pumping house. The volume of the reservoir in front of the pumping house is related to many factors in the actual operation of the waterworks and needs to be determined reasonably.更多还原
