单因子混凝加药系统在原水预处理中的应用

The application of sole-factor automatic coagulant-adding system in water treatment process

混凝是火电厂水处理工艺中最重要的环节之一,原水混凝处理效果的好坏直接影响到后续的水处理过程。单因子混凝加药测控系统就是通过监测原水中胶体混凝后产生的流动电流,根据流动电流变化来调节混凝剂加药量,实现预处理混凝剂加药的自动控制。本文介绍了单因子混凝加药测控系统在贵溪发电有限责任公司原水预处理中的应用情况。

Coagulant is one of important links during the water treatment in thermal power station, the result of coagulant disposing for raw water have direct effect on water treatment process. Through monitoring streaming current produced by coagulant colloid in raw water,sole-factor automatic coagulant-adding system accomplish automatic control by modulating dose amount according to the change of streaming current. This paper introduced the application of sole-factor automatic coagulant-adding system in Guixi power station.
