以黄河水为水源的净水厂预处理工艺

Pretreatment process of the water purification plant with the Yellow River as the water source

介绍了以黄河水为水源的河南省某城区净水厂的预处理工艺选择。黄河水泥沙含量较高,部分有机物指标超标,常规水处理工艺无法满足出水水质要求,需增加预处理设施。针对来水水质,采用化学预处理+生物预处理相结合的工艺对黄河水进行处理,后经常规处理,可使出水水质满足生活饮用水水质要求。

The pretreatment technology of the water purification plant with the Yellow River as the water source in Henan province was introduced. Because the Yellow River sediment concentration is high and the organic matter has beyond the standard, the water quality cannot meet the requirement with the conventional water treatment process, and the pretreatment processes have to been in- creased. According to the water quality, the chemical pretreatment and biological pretreatment processes have been adopted. Then through the conventional treatment, the water quality can meet the requirement of drinking water quality
