摘　　要：饮用水水质安全是关乎民生的重要问题,而市政供水管网的停水事件会显著影响水质安全。停水期间,管网内水流停滞或减缓,导致微生物再生长现象严重。恢复供水时,由于管道内水力条件的突然变化,松散沉积物、生物膜以及病原微生物等易被冲刷进入水体,导致水质短期恶化。本文系统探讨了停水事件对市政供水管网水质的影响,重点分析了余氯衰减、浊度增加、重金属释放、微生物污染及恢复供水后的水质波动,并给出了降低停水带来水质风险的建议。The safety of drinking water quality is a critical issue for public well-being,and water supply interruptions in drinking water distribution systems can significantly impact water quality.During interruptions,water stagnation or reduced flow within the pipeline promotes microbial regrowth.Upon restoration of the water supply,sudden changes in hydraulic conditions may lead to the mobilization of loose deposits,biofilms,and pathogenic microorganisms into the water,resulting in short-term water quality deterioration.This review systematically explores the effects of water supply interruptions on the water quality of drinking water distribution systems,with a focus on chlorine decay,turbidity increase,heavy metal release,microbial contamination,and water quality fluctuations during supply restoration.Finally,recommendations are proposed to mitigate water quality risks associated with supply interruptions.
