摘　　要：以供水管网模拟系统为试验平台,采用多点投加高浓度次氯酸钠溶液模拟污染物扩散的方法进行了试验研究与理论分析.通过实测监测点污染信息,利用改进的模拟-优化反追踪模型进行污染源定位并分析管网拓扑结构等影响因素对模型效率及准确率的影响.研究表明,在影响因素合理表达条件下,可以实现模型的高准确率.The sodium hypochlorite solution, which was used to simulate the contamination, was introduced from different intrusion points to the small-scale experimental and open water distribution system,and then the experimental study and theoretical analysis of contamination source identification were carried out. By monitoring concentration data measured, the simulation-optimization method was applied to the identification of locations of contamination sources. Water network topologic structure and other factors were analyzed, which influence the model＇s efficency and accuracy. Simulation results demonstrate that under the conditions of factors expressed appropriately, the high accuracy of the model can be achieved.
