摘要
城市供水管道腐蚀和结垢,不仅会降低管网的供水能力,还会影响供水水质,因此对供水管网进行更新改造具有重要意义。依托某小区供水管网喷涂修复工程,阐述了环氧树脂喷涂修复工艺和喷涂改造对供水水质的影响。结果表明,经环氧树脂喷涂修复后,水质有较大程度的改善,浊度、TOC、Mn和Pb浓度都有明显的降低,pH值和余氯浓度变化不明显。
Corrosion and scaling in water distribution systems can decrease the water supply capacity and affect water quality. Therefore, it is of great significance to upgrade water distribution systems. The epoxy resin spraying process and its influence on water quality were described based on a real epoxy resin spraying project in a community. The results showed that after epoxy resin spraying, turbidity, TOC, Mn and Pb were significantly reduced, and pH and residual chlorine had no obvious change.
