强化混凝技术在黄河下游水厂的应用

Application of enhanced coagulation at a water plant in the downstream of Yellow River

强化混凝是一种具有多重目标的混凝过程,是对整个给水系统综合、系统化的工艺过程。在黄河下游水厂进行了强化混凝技术的应用试验。实验结果表明:采用高锰酸钾复合药剂预氧化,浊度去除率提高20%,高锰酸盐指数去除率提高26%,使出厂水水质得到了进一步提高。南郊水厂通过强化混凝技术,提高了现有常规给水工艺去除污染物的效能,使出厂水水质满足国家新的饮用水水质标准。

Enhanced coagulation is a water treatment process for multi-goals that could make the whole water supply process integrated and systemized.Application of the enhanced coagulation technology is carried out in a water plant near the downstream of the Yellow River.The test indicates that pre-oxidation with potassium permanganate compound may increase the removal of the turbidity by 20%,CODMn by 26%,which benefits the water quality.In the Nanjiao Water works,the efficiency of the existing convention process is promoted by the implementation of enhanced coagulation,resulting in quality water to meet the requirement of current national tap water standard.
