Abstract:

A polyferric silicate sulfate(PFSS) flocculant has been prepared by using Na2SiO3、H2SO4and Fe2(SO4)3as raw materials according to compound co-polymerization.The pH value , SiO2content and temperature have different effects on the process of silicate preparation.The influence of molar ratio of Fe3+/SiO2on the stability of PFSS and removal rate of CODcr has been
studied.Results have shown that optimally-prepared-PFSS has more advantages than PFS and PAC on decoloration and removal rate of CODcr , and has widely applied prospects.

Key words: polyferric silicate sulfate, compound co-polymerization, flocculant
