摘要：
以Na2SiO3、H2SO4和Fe2(SO4)3为主要原料,采用复合共聚生产工艺,制备了聚硅硫酸铁絮凝剂(PFSS)。研究了pH值、SiO2含量、温度对硅酸聚合过程的影响,并考察了Fe3+/SiO2摩尔比对PFSS稳定性和CODcr去除率的影响。结果表明,在最佳条件下合成的PFSS在脱色、CODcr去除率方面比PFS和PAC效果更显著,具有广阔的应用前景。
关键词: 聚硅硫酸铁, 复合共聚, 絮凝剂
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 beenstudied.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
