摘　　要：为探究供水管网分区对加氯策略的影响,采用“模拟-优化”框架,提出了一种有效控制管网分区后余氯浓度的加氯策略优化方法。基于J案例管网的结果显示,管网加氯总量、加氯站数量和加氯复杂度之间存在明显的权衡关系。在保障节点水质安全的前提下,分区后的优化方案比分区前最多可节约氯耗达46.8%。管网分区会对原有加氯方案下的管网水质产生负面影响。二次加氯方式越灵活,分区后关键节点水质受到的负面影响越小。为保障分区后的水质安全,需要重新调整加氯方案,并适当增加总的氯投加量。建议在制订管网分区方案时将分区后对管网加氯的影响纳入成本效益分析过程,协调控漏效益与药耗增量之间的矛盾关系。To investigate the impact of water supply network partition on chlorination strategies,an optimization method was developed using simulation-optimization framework to effectively manage residual chlorine following network partition.The results based on the J case pipeline network revealed a significant trade-off among the total chlorine dosage within the network,the number of chlorination stations,and the complexity of the chlorination.Under the premise of ensuring water quality safety at all nodes,the optimized scheme following network partition achieved a chlorine consumption reduction of up to 46.8%compared to the scheme before partition.The implementation of network partition is likely to adversely affect the original chlorination scheme.A more adaptable secondary chlorination approach can mitigate the potential negative impact on water quality at critical nodes following the network partition.To ensure the safety of water quality following the implementation of network partition,it is imperative to reassess and readjust the chlorination strategy,including a moderate increase in the total chlorine dosage.It is recommended that the impact of network partition on chlorination should be incorporated into the cost-benefit analysis process when planning the network partition,so as to address the conflicting relationship between leakage control benefits and increased chlorine consumption.
