摘　　要：以开环式供水管网模拟系统为试验平台,采用高浓度次氯酸钠溶液进行多点投加,测取监测点相应污染物浓度的时变数据,并以此作为监测数据资源,利用基于拉格朗日法的反追踪技术定位污染源,并深入探讨了该模型的可行性以及影响模型效率和准确率的因素。Taking the simulation system for open water distribution system as an experimental platform, through addition of high-concentration sodium hypochlorite solution at multiple points, the time-varying data of contaminant concentration at the monitoring points are collected and used as data resource. The origin tracking technique based on the Lagrangian algorithm is used to determine the location of contamination source. The feasibility of the model and the factors affecting the efficiency and accuracy of the model are discussed.
