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。
Through the analysis of the origin of the sudden yellow water phenomenon in the water supply network of Meisha Area in Shenzhen, it is clear that the water quality changes when the water source is switched over. Especially the decrease of chemical stability of water quality caused by the decrease of pH value is the main reason for yellow water production in this area. The water plant adopts the method of adding lime to improve the chemical stability of water quality. When the pH value of the produced water is controlled to be 8.0-8.5, the method can effectively improve the chemical stability of the water quality of the produced water and achieve the purpose of controlling the corrosion of the water pipe network .
