摘　　要：供水管网漏损控制有助于降低水量损耗、节约水资源利用,且可以提高供水行业企业的效益。当前大多通过主动检漏并及时修复的措施控制漏损,然而实际管网结构复杂,检漏和修复技术难度、响应时间和成本均较高,压力管理能快速有效降低漏损并节约能耗。文中讨论了供水管网漏损评估及其控制方法,提出了表观损失和真实损失的不同控制方案,对比分析了真实损失控制方法中压力管理策略的不同形式,通过设置减压阀将压力管理策略应用于X市供水管网分析。经模拟,X市背景漏损水量可降低7.4%,验证了压力管理对漏损控制的有效性。Leakage control of water distribution network can not only reduce losses and save resources,but also improve the efficiency of enterprises in water supply industry.Most of the current researches use active leakage detection and timely repair measures to control leakage.But complicated water distribution system structure greatly increases technical difficulty,response time and cost.Pressure management strategy can quickly and effectively reduce leakage and save energy.Therefore,some methods of evaluation and the control of leakage were presented in this article.Different solutions to apparent leakages and real leakages were also proposed.Different forms of pressure management methods in Real Leakages control were compared and analyzed.Pressure management strategy by setting pressure reducing valve was applied to a city.Simulation results showed that background leakage could be reduced by 7.4%,which verified the effectiveness of pressure management for leakage control.Research had guiding significance for leakage control in water distribution system.
