摘要
通过烧杯实验,研究了聚合硫酸铁(PFS)、硫酸铝(AS)的各自强化混凝条件,并通过ξ电位的测定解释了 PFS和硫酸铝的混凝机理;经过沉淀性能对比实验得出PFS+PAM的絮体沉降性能远远好于硫酸铝的絮体沉降性能;通过PFS的正交优化实验确定了影响PFS的混凝性能的因素的主次顺序以及最佳因素水平。
The enhanced coagulation condition of polyferric sulfate （PFS） and aluminum sulfate （AS） were studied byjar tests and their Zeta potentials were measured to explain their coagulating mechanism, the results of experimentsindicated that the floc＇s sedimentation property of PFS＋PAM is much more better than that of AS. Through the PFS orthogonal test the main and minor factors in fluencing the coagulation property were determined.
