| 摘 要： | 相较于区域计量分区(DMA),管网区块化(DBS)供水分区管理系统不但可以实现用水量的分区计量,而且能实现均衡水压和水龄、优化水质和降漏节能等作用,并且不会降低管网在事故状态下供水的可靠性。进水点数量和位置的确定是DBS分区管理的关键步骤,以重庆市巴南区鹿角—界石组团的界石供水区域管网为例,根据DBS分区方法,利用EPANET 2. 0软件模拟区块化供水管网系统的进水点数量和位置,对比不同供水条件下管网水压、水龄及建设运行费用,分析进水点数量和位置的确定方法。

| Abstract: | Compared with district metering area ( DMA), distribution blocking system ( DBS) can not only realize water partition measurement, but also achieve the function of balancing water pressure and age, optimizing water quality, reducing leakage and saving energy. In addition, it won't reduce the reliability of water supply network in an accident situation. The determination of influent point number and location is the key step of DBS. According to the DBS partition method, number and location of different influent points were determined through simulation of blocking water supply network system by using EPANET 2. 0 software in Lujiao - Jieshi group, Banan district, Chongqing. Water pressure, water age and construction costs under different water supply condition were compared, and the methods for determining influent point number and location were summarized. |
