| 摘要: |
| 讨论不同pH值条件下合成的聚硅酸铝盐的絮凝特点、不同硅氧基与铝离子摩尔比聚合而成的产物的絮凝行为。该聚合物在不同pH值的原水中其絮凝性能非常一致,与相同浓度的简单无机铁、铝盐类相比,具有用量少,絮凝速度快,沉淀分离彻底等优点,并以此为基础,定性地分析了聚硅酸铝盐的絮凝性能、聚凝机理与该无机高分子的结构的关系。 |

| Abstract: |
| The flocculability of PSA(Polymer Silica Aluminium) formed in different pH values, the flocculent characteristics of PSA synthetized in varied Si-O/Al3+ molar ratios are dealt with in this paper.The PAS is possessed of almost same properties of flocculent in raw water with different pH values, and have the advantages of less consumption,faster flocculation,more completely sedimentation seperation than same concentration of simple inorganic iron or aluminium salts.Upon the base,the relation between property,mechanism of flocculence and it is inorganic polymer structure of PAS is discovered qualitatively. |
