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 open-loop water supply network simulation system as test platform, high-concentration sodium hypochlorite solution was used for multi-point dosing, time-varying data of corresponding pollutant concentrations at monitoring points were measured and used as monitoring data resources. Based on Lagrangian The anti-tracking technology of Japanese law locates the sources of pollution and discusses in depth the feasibility of the model and the factors that influence the efficiency and accuracy of the model.
