摘要
通过测定絮凝体的分形维数判断聚合磷硫酸铁的絮凝效果,并结合分形理论,利用正交设计原理,对絮凝体形成的影响因素OH-/Fe,PO43-/Fe、硫酸铁投加量进行研究。结果表明,聚合磷硫酸铁絮凝最佳条件为:OH-∶Fe=2∶5,PO43-∶Fe=1∶20,1 mol/L硫酸铁溶液的投加量5 mL/L。
Flocculation effect of polymeric ferric phosphoric sulfate was judged according to the fractal dimension. Combining of fractal theory and using orthogonal design principle, OH^-/Fe, PO4^3-/Fe and the dosage of ferric sulfate on the formation of flocculant was researched and the best coagulation conditions was made. The best coagulation polymerization conditions of polymeric ferric phosphoric sulfate is: OH^- : Fe = 2 : 5, PO4^3- : Fe = 1 : 20, the best dosage of 5 mL/L.
