摘　　要：为系统地研究多水源供水管网中余氯随节点水龄的变化规律,运用Microsoft Visual C++编程对某大城市局部供水管网进行供水区域划分,并结合MFC开发系统将每个供水区域以界面形式显示出来。运用EPANET 2计算管网节点水龄值和余氯值,并用实测余氯值进行参数率定。以每一个供水水源为起点、其供水区域内的管网末梢为终点,将每个节点余氯值和水龄值进行曲线拟合分析,得到拟合方程,这为进一步应用节点水龄评价管网水质提供了理论依据,也为水质安全保障及供水系统的调度管理提供了技术支撑。In order to systematically study the variation of residual chlorine in multi-source water supply network with node age, Microsoft Visual C ＋ ＋ was used to make a division of the multi-source water supply network of a city. At the same time, each zone was showed on the interface by combining MFC development system. The node age and residual chlorine were calculated by EPANET 2, and the parameter calibration was performed by the measured residual chlorine value. Taking each source as the starting point, and the end point of its supply area as the terminal point, the curve fitting of the residual chlorine and node age was done, and the fitted equation was obtained, which provided theoretical founda- tion for evaluating water quality by node age, and technical support for water quality security assurance and dispatching management of water supply network.
