摘要
PFASSi的形态分布研究表明,它的最优技术指标为B=1.5～2.0,Fe+Al/Si或Fe/Al摩尔比均为10:1,pH为2.0～4.0,熟化24h;硅的加入会产生很强的协同效应,使无机高分子絮凝剂PFASSi较单纯聚硅酸和单纯的聚铁的絮凝能力增强很多,有效成分高,絮凝效果更好。
The studying results of the species distribution of PFASSi show that the optimal technical indexes of PFASSi product are as follows: B=1.5-2.0, (n(Fe) + n(Al))/n(Si) or n(Fe)/n(Al) = 10= 1, pH = 2.0-4.0 and valid concentration is about 0.2 - 0.4 mol/L. The Si affiliation is strongly in conjunction with the effect. This makes flocculant effectiveness of PFASSi. Compared with polysilicic and polyferric, the validity composition is high and the result of flocculant is better.
