城市供水产销差率与漏损控制研究进展

Research progress of non-revenue water and leakage control of urban water supply system

针对产销差率居高不下这一供水行业问题,研究了供水产销差率的定义和组成、水平衡分析、国内外供水产销差率及漏损现状,以及当前控制产销差率、漏损率的技术和方法,如DMA(district metering area)分区、管网压力控制、检漏工具和管网建模等。降低产销差率是一项综合性的任务,需各种措施共同施用,才能有效提升供水企业的效益。

Aiming at the problem of high rate of NRW （ non-revenue water） in water supply system, the paper studied the definition and components of NRW, water balance analysis, present situation of NRW and leakage at home and abroad. Besides, the existing control techniques and methods of NRW and leakage control, such as district metering area, pipe network pressure control, leakage detection tools and pipe network modeling, have also been introduced here. In the end, reduction of NRW is a comprehensive task, so a variety of measures should be taken together to effectively improve the benefits of water supply enterprises.
