| 摘 要： | 通过深圳梅沙片区供水管网突发黄水现象的成因分析,明确水源切换时水质发生了变化,特别是pH值降低引起的水质化学稳定性下降是该区黄水产生的主要原因。水厂采用投加石灰的方法提高水质化学稳定性,当控制出厂水的pH值为8.0～8.5时,该方法可有效提高出厂水的水质化学稳定性,实现水厂内控制管网腐蚀的目的。

| Abstract: | The yellow water phenomenon in the water distribution system in Meisha District was analyzed.It was found that the water quality change during water source switch,especially the decrease in chemical stability caused by low pH,were responsible for the presence of yellow water.The chemical stability was improved by adding lime and controlling the pH of the finished water at between 8.0 and 8.5.The aim of controlling pipe corrosion was achieved. |

| Keywords: | yellow water pH value water quality chemical stability lime |
