摘要
以硅酸钠、硫酸铝和硫酸铁为原料,采用复合共聚法制备出聚硅硫酸铝(PASS)和聚硅硫酸铁(PFSS),分别以聚硅硫酸铝、聚硅硫酸铁和两者与天然粘土的复配为混凝剂,观察净化处理后的藻类污水颜色的变化以及对溶液浊度、耗氧量(COD)的测定,考察4种混凝剂对藻类污水絮凝效果的优异。结果表明:复配后的混凝剂对藻类污水的絮凝效果明显要好于单组分的混凝剂,其中以聚硅硫酸铝与粘土复配所产生的絮凝效果最佳。
PASS and PFSS were prepared by composite - copolymerization with NaSiO3, Al2 （SO4）3 and Fe2 （SO4）3 as raw materials, respectively. Using PASS, PFSS they were built with clay as coagulating agents, the effect of floecuiation on algae sewerage treated four coagulating agents was investigated through change of algae sewerage, its turbidity and COD determined. The results showed built coagulating agents were superior to single coagulating agent for fiocculation property of algae sewerage, while PASS and clay built could gain best performance among of them.
