摘要
以钛白粉厂副产硫酸亚铁和浓硫酸为主要原料，通过加入非亚硝酸盐氧化催化剂及助催化剂进行常温氧化、水解、聚合制备出聚合硫酸铁混凝剂。该混凝剂净水效果好。
The ferric polysulfate coagulant is made by ferrous sulfate,which is a by-product from TiO_2 plant,and concentrated sulfuric acid in the presence of non-nitrous salt catalyst at normal temperature through oxidation,hydrolysis and polymerization.It is suitable for the purification of sewage and drinking water at either low temperature and turbidity or high temperature and turbidity.
