摘要
某超大城市供水范围内,整体地形呈西北高东南低的趋势,主力水厂采用西北向东南的自然坡降重力供水方式。2021年该地区供水管网漏损率约9.58%,由于超大城市供水范围大、管网分布复杂、漏损原因多样,亟需系统控制。通过强化管网改造、优化压力调控、推动分区计量、完善信息化管理等方法,提出超大城市管网漏损系统控制策略,分析其节水潜力。结果表明:针对超大城市供水管网渗损,通过系统控制,在保障供水安全的同时,可实现节水约2611万m^(3)、节能约988002.4kWh、降碳1051.2 t的目标。
In the water supply area of a mega-city,the overall topography is high in the northwest and low in the southeast;therefore,the main water plant adopts the natural gradient gravity water supply mode from northwest to southeast.In 2021,the leakage of water supply network in this area is about 9.58%.Due to the large range of water supply,complex distribution of pipe network and various leakage causes in mega-cities,system control is urgently needed.By strengthening pipe network transformation,optimizing pressure regulation,promoting zone metering system,and improving information management,a control strategy for the leakage system of mega-city pipeline network is proposed and its water-saving potential is analyzed.The results show that the system control of pipe network leakage can achieve the goals of saving water of about 26.11 million cubic meters,saving energy of about 988002.4 kilowatt-hours,and reducing carbon emissions of 1051.2 tons.
