| 摘 要： | 制备了不同 Fe/Si含量比的聚硅酸硫酸铁 (PSFS)。比较了不同 Fe/Si的 PSFS的絮凝效果及稳定性 ,实验了 p H值及絮凝剂用量对絮凝效果的影响。研究表明 ,当 p H=3左右 ,Fe/Si含量比为 1∶ 2时制备的PSFS具有较好的絮凝效果。在实验条件下 ,絮凝剂的最佳用量为 8mg/L。

| Abstract: | A new type of flocculant—polyferric silicate sulfate(PSFS) with different value of Fe/Si (molar ratio) was prepared in this paper,and comparing their flocculation efficiency and stability.The results show that the optimum conditions of preparation are pH=3,Fe/Si=1∶2,then PSFS has the best flocculation.Under the experimental conditions,the optimum dosage of PSFS is 8mg/L. |
