【摘要】 制备了含不同金属离子的聚硅酸盐混凝剂 (PMSS) ,考察了投加量、水样pH值、熟化时间和PMSS中硅酸含量等因素对其混凝性能的影响。并通过分析金属离子一级水解常数与混凝效果之间的关系 ,初步探讨了金属离子的水解聚合行为对PMSS混凝性能的影响机理。结果表明 ,PMSS的混凝性能与金属离子的水解聚合行为及硅酸的含量和结构有关。更多还原

【Abstract】 The ploymetal silitcate sulfate (PMSS) was prepared.The influences of the additive amount,aging time,the SiO 2/M molar ratio of PMSS,and the pH of water on its coagulation property were investigated,and the mechanism of the degree of hydrolyzation and polymerization of metal on its property was mainly discussed.The results show that the hydrolyzation and polymerization of metal and the structure of polysilicate has great effect on the coagulation property of PMSS.更多还原
