Abstract

A new kind of polymer inorganic coagulant-PFSiS (Poly Ferric Silicate Sulphate) coagulants, at different Fe/Si molar ratios and B values ( B =OH/Fe) were prepared. Then, the turbidity removal efficiency of PFSiS in treating kaolin suspension was investigated. The results showed that turbidity was removed highly by using PFSiS under the certain conditions. Moreover, FTIR analysis indicated that Si participated hydrolytic process of Fe(III). Oil and COD removal efficiency of PFSiS in treating oily wastewater were also evaluated. Under the optimum conditions, oil removal efficiency in the range of 95-97% and more than 60% of COD was removed. Additionally, the PFSiS coagulants exhibited a better coagulation performance than polymer inorganic coagulant, i.e. PFS (Poly Ferric Sulphate).

聚硅酸铁硫酸盐(PFSiS):表征、混凝行为及其在含油废水处理中的应用

制备了不同Fe/Si摩尔比和B值(B =OH/Fe)下的新型高分子无机混凝剂pfsis(聚硅酸铁)。然后考察了pfsi对高岭土悬浮液的除浊效果。结果表明，在一定条件下，pfsi能较好地去除浊度。FTIR分析表明，Si参与了Fe(III)的水解过程。评价了pfsi处理含油废水的除油效果和COD去除率。在最佳条件下，除油率在95 ~ 97%之间，COD去除率在60%以上。此外，pfsi混凝剂的混凝性能优于高分子无机混凝剂PFS(聚硫酸铁)。
