摘要
随着经济社会发展,城镇化进程加快,水资源供需矛盾短缺日趋严重,而城市供水管网漏损,是目前困扰节水的难题之一,供水管网漏损控制已成为“十四五”城市供水行业的重点工作之一。文章简要介绍了供水管网漏损的原因和主要控制方法。重点结合水司自身特点,分析了实际工程应用成效,主要包括:推进独立计量区(DMA)进行的夜间最小流量监控;开展日常巡检及周期性检漏;定期开展水表轮换;改造老旧管网;布设管网压力监测点;加装水池水箱远程监控。而通过各种不同控制手段的结合使用,有效地控制了管网漏损,2023年综合漏损率降低为10%,研究成果以期为各水司供水管网的漏损控制提供指导和借鉴。
With the development of the economy and society,the process of urbanization is accelerated.The contradiction between water resource supply and demand is becoming increasingly serious.The leakage of water supply pipelines network is one of the problems of water saving.The leakage control of water supply pipelines networks has become one of the key tasks of urban water supply industry in the 14th Five-Year.This paper briefly introduces the causes and main control methods of water supply pipelines network leakage.Focusing on analyzing the actual engineering application effectiveness based on the characteristics of the water supply company itself,mainly including:monitoring the minimum flow at night by constructing on district metered area(DMA);carrying out daily inspection and periodic leakage detection;regular water meter rotation;reconstructing old pipelines network;setting up pressure monitoring points and adding remote monitoring of water tank.By combining various control methods,the water supply pipelines networks leakage has been effectively controlled and the comprehensive leakage rate of 2023 has been reduced to 10%.The research results are expected to provide guidance and reference for the leakage control of the water supply pipelines network of various water supply companies.
