摘    要:在水处理领域,特性聚硅酸是处理低温低浊水时应用比较广泛的絮凝剂,同时特性聚性酸也是聚硅酸盐类絮凝剂的重要组成部分。论述了在酸性条件下制备特性聚硅酸的最佳聚合反应条件,提出了向酸中加入水玻璃这一不同于传统制备聚硅酸的方法。结温度、pH值、二氧化硅的浓度及高价金属阳离子的影响进行了研究。

关 键 词:絮凝剂  特性聚硅酸  制备  水处理  硅酸盐  低温低浊水  水玻璃

Abstract:Characteristic polymerize silicic acid is a kind of flocculant in water treatment domain used in treating water at low temperature and low turbidity,and characteristic polymerized silicic acid is also an important component of polysillcate flocculant.The best polymerize reaction condition to make characteristic polymerize silicic acid in an acidic environment is reviewed and the addition of soluble glass into acid in a way different from the traditional one is put forward to make polymeriza-tion silicic acid,and the influences of temperature,pH value,thickness of silicon dioxide,and high electropositive ion are in vestigated.
Keywords:flocculant  characteristic polymerize d silicic acid  make  conditions for polymerized reac-tion  water treatment  silicate  low temperature and low turbidity  soluble glass
