摘　　要：简述了真空排水管网的输送机理及设计方法,对真空排水管网设计和运行所涉及的若干重要参数的确定原理进行了说明。理论分析了真空排水系统的能耗,指出系统的单位能耗取决于系统工作的真空度及输送污水的气液比,并给出其估算方法。此外,对如何降低系统能耗提出了建议。The conveying mechanism and design method of vacuum drainage network are briefly reviewed. The determination principle of several important parameters involved in design and operation of vacuum drainage network is described. Through theoretically analyzing the energy consumption of vacuum sewerage system, it is pointed out that the specific energy consumption of vacuum sewerage system depends on the operation vacuum degree and gas-liquid ratio for sewage conveying. An estimation approach for the specific energy consumption is presented, and suggestions to reduce system energy consumption are made.
