摘要
DMA技术已成为许多大中城市自来水企业降低供水管网漏损的重要手段之一.以某小区漏损分析及控制为例,介绍DMA技术用于供水管网漏损控制的经验.实践证明,小区建立DMA后,通过实时监测小区的夜间最小流量,可以有效识别物理漏损;通过建立小区二级DMA,可以有效找出可能存在的户表后物理漏损,从而进一步精准定位并修复漏点,降低自来水企业的管网漏损水量.
Abstract
DMA technology has become one of the important means for many large and medium-sized urban water companies to reduce water supply network leakage.Taking the analysis and control of leakage in a certain residential area as an example,this article introduced the experience of DMA technology in water supply network leakage control.Practice had proven that after establishing DMA in a residential area,physical leakage could be effectively identified by real-time monitoring of the minimum night flow in the community.By establishing a secondary DMA in the community,it was possible to effectively identify possible physical water leakage in the household table,thereby further accurately locating and repairing the leakage points,and reducing the water leakage in the water supply network of the water company.
