摘　　要：提出了一种二级嵌套优化方法,用于研究供水管网的二次加氯优化问题。首先,基于管网水质机理模型,通过最大集覆盖理论对加氯点的优化选址进行深入分析,并提出了一种余氯覆盖集选取策略。其次,采用基于用水量权重的加氯量优化模型,以确定最优的加氯方案。此模型被应用于南方某城市的一个大型实际管网,计算结果证实,二次加氯方案可以有效地确保管网末端的余氯浓度,并实现管网中余氯的均衡分布。This paper proposes a two-level nested optimization method for the optimization of cascade chlorine injection in water distribution networks.Initially,based on the water quality mechanism model of the network,the chlorine injection point selection is conducted using the theory of maximum set coverage,and a strategy for selecting chlorine residual coverage sets is introduced.Subsequently,an optimization model for chlorine dosage,weighted by water usage,is utilized to identify the optimal chlorine dosage.This model has been applied to a large real water network in a city in southern China.The results validate that cascade chlorine injection can effectively ensure the chlorine residual concentration at the end of the network and achieve a balanced distribution of chlorine residual throughout the network.
