【摘要】：研究了给水管网突发污染水质监测点选址的方法,分析了覆盖集法存在的缺陷,并针对这些缺陷提出了一个基于覆盖集原理模型的改进方法,即在基于覆盖集法的突发污染水质监测点优化选址模型中引入报警域,同时考虑节点发生污染事件的概率。为了验证改进模型的合理性,将传统覆盖集法和改进的覆盖集法应用于同一个案例管网优化选址分析,结果表明改进的覆盖集法求得的选址方案更合理。
[Abstract]:This paper studies the site selection method of water supply pipe network for sudden pollution water quality monitoring points, analyzes the defects of coverage set method, and puts forward an improved method based on the principle model of coverage set for these defects. In order to verify the rationality of the improved model, an alarm region is introduced into the optimal site selection model of sudden pollution monitoring points based on the coverage set method, and the probability of the node pollution events is considered at the same time. The traditional covering set method and the improved covering set method are applied to the optimization location analysis of the same case pipe network. The results show that the improved covering set method is more reasonable.

【正文快照】： 供水管网中水质发生变化的原因主要有两种:一是在管网的输送过程中水与管壁发生物理的、化学的或生物的反应[1,2];二是在输送过程中受到二次污染,外部的污染物进入管网系统[3,4]。为了及时监测到供水管网中水质的变化,供水管理部门通常在管网中布置若干个水质监测点[5,6]。考
