混凝剂的一般混凝机理及聚合硫酸铁的混凝作用

通过科研和生产实践,运用物理化学和无机化学的基础原理,对混凝剂的一般混凝机理及聚合硫酸铁的混凝作用进行了初步探讨,发现聚合硫酸铁混凝效果甚好,这是因为,一方面高价的格阳离子能有效的降低胶粒和固体粒子的ζ—电势,另一方面是由于大的分子质量和分子的桥联结构具有较强的桥联吸附作用,使细粒凝聚体和细小悬浮体形成大的絮团,同时吸附原水中的杂质性离子、浮游物及微生物成为沉淀除掉。

General Coagulating Mechanism of Coagulants and Coagulating Fonctions of Poly Ferric Sulfate

According to our scientific researchs and productional practices, we made pretiminary studies on the general coagulating mechanism of coagulants and coagulating functions of poly ferric sulfate by applying to some basic rules in reference to the PhysicoChernical and inorganic chemical. From the studies, some causes of poly ferric sulfate having fine coagulating effection have been found, which may be on the one hand its high valent complex kation can efficient lower zeta potential of colloidal particl and solids. On the other hand its big molecular weight and bridge linkang structure, have serengthened bridge linkang absorption so that it can make the minute floccules and little suspended particles some big floes meanwhile absorbing impure inos floating matters and microbes of natural water and then removing by precipitating together.
