摘　　要：铁质金属供水管道是我国使用最广泛的供水管材,其腐蚀问题是导致管网漏失和爆裂的主要原因。长期运行过程中,管道内壁腐蚀生成的不规则腐蚀管垢,不仅会降低管网的输送能力,还会发生铁释放导致的"红水"现象,严重影响管网的安全稳定运行。分别从腐蚀研究方法、腐蚀影响因素、腐蚀管垢研究以及非常规水源进入管网引起的腐蚀问题等四个方面,综述了铁质金属供水管道的内腐蚀研究进展,并对目前供水管道腐蚀研究存在的局限性进行了总结,进而提出了面向未来的供水管道腐蚀研究新方法和新思路,以期从本质上掌握铁质供水管道的腐蚀问题及其引起的管网水质恶化的症结,并准确揭示供水管网的水质稳定性控制机制,从而为保证供水管网的安全运行奠定坚实的理论基础。Iron-metal pipe is the most widely used in water distribution systems( WDS) in China,and its corrosion is the main cause of pipe network leakage and burst.In the process of long-term operation,the irregular corrosion scale produced by the corrosion of the inner wall of the pipe will not only reduce the conveying capacity of the WDS,but also lead to the phenomenon of "red water"caused by iron release,which seriously affects the safe and stable operation of the WDS.This paper respectively reviewed the research progress of internal corrosion of the iron-metal WDS from the following four aspects:the corrosion research methods,corrosion influence factors,pipe corrosion scales research,and the problem of corrosion caused by unconventional water entering the WDS.The limitations of the current WDS corrosion research was summarized,and then new methods and ideas of the WDS corrosion was put forward,in order to fundamentally control the corrosion problem of the iron-metal WDS,and reveal the cause of the water quality deterioration and the control mechanism of water quality stability.Finally,a solid theoretical foundation was established in order to ensure the safe operation of WDS.
