Abstract

A method for preparing inorganic macromolecular flocculant by polymerizing silicate and zirconium tetrachloride is disclosed and relates to the field of feed water treatment. The invention aims at the problem of poor efficiency of inorganic low-molecular zirconium salt flocculant in treating low-temperature raw water and blockage of flocculation, by copolymerization of polymeric zirconium chloride and polysilicic acid, the Si—O—Zr bond was formed to increase the molecular chain of the flocculant to strengthen the function of adsorption bridge and net capture sweep. Under low temperature, the flocculant can remove organic pollutants effectively, and the size of flocs formed is large and easy to precipitate. The invention is particularly suitable for the treatment of raw water at low temperature, low turbidity and high organics by enhanced coagulation.
