水源切换对供水管网铁释放影响及控制技术研究进展

Control technology and research progress on influence of water source switch on iron release in water supply network

针对南水北调通水后北方受水区城市水源切换引起铁释放的问题,通过阐述管网腐蚀机理,重点从水质条件和水力条件分析了水源切换过程中影响水质稳定性的因素。在此基础上,从管网管理、管网改造与维护、管网水质调节技术三方面,提出了水源切换引起管网铁释放的控制措施和建议。

Aiming at the issues of iron release during the process of water diversion from south to north project,based on the analysis of the corrosion mechanism of network,the causes of water quality stability were analyzed from the factors of water quality and hydraulic conditions. The impact of the control measures and suggestions for the iron release from network were proposed from the aspects of network management,network renovation and maintenance,and water quality control technology of network.
