国外于1938年开始应用微观电泳技术研究给水混凝机理,迄至60年代自来水厂才用此来控制混凝剂投加量,这是保证水质的一种经济有效的技术措施。给水处理的混凝作用,主要是凝聚水中分散的胶体与微悬浮颗粒。为使其在水中迅速有效的凝聚,必须降低其流动电位(亦称 In 1938, micro-electrophoresis technology was used to study the coagulation mechanism of water supply in foreign countries. It was not until the 1960s that the water plant used this to control the dosage of coagulant. This is a cost-effective technical measure to ensure water quality. The coagulation action of water treatment is mainly the condensed colloid and micro-suspension particles in condensed water. In order to make it quickly and effectively condense in water, its flow potential must be reduced (also known as
