城市供水管网分区供水技术研究

Study on Water Supply Technology of Urban Water Supply Network

近年来,很多城市的自来水公司都出现了供水管网漏损的问题。城市管网漏失率居高不下,严重制约了城市经济的发展,也加剧了水资源的浪费。人们对城市管线漏损的控制越来越重视,开始采取积极措施来解决供水管网的漏损问题。构建独立计量区域(DMA)是一种控制供水管网漏失的有效方法,本文对控制管网漏损的DMA方法进行了阐述,解析了构建DMA的关键步骤,并提出了构建DMA的有效策略。

In recent years, many cities in the water company have a water supply pipe network leakage problems. Urban pipe network leakage rate is high, seriously restricting the development of urban economy, but also exacerbated the waste of water resources. People are increasingly concerned about the control of urban pipeline leakage, began to take positive measures to solve the problem of water supply pipe network leakage. The construction of independent metering area（DMA） is an effective method to control the loss of water supply network. In this paper, the DMA method of pipe network leakage is described, the key steps of constructing DMA are analyzed, and the effective strategy of constructing DMA is put forward.
