| 摘 要： | 以硅酸钠、硫骏、硫酸铝为原料制备含右铝离子的聚硅酸絮凝剂(简称PSAA),试验它的絮凝特性及影响因素,并与聚合氯化铝(简称PAC)的絮凝效果进行比较。实验结果表明,铝离子的含量对PSAA的絮凝特性影响很大,当Al~(3+)/siO_2的摩尔比为1时絮凝效果最好,在pH=5—10的范围内,PSAA具有良好的絮凝效果。与PAC相比,PSAA具有絮凝效果好、价格低廉、适用的pH范围较宽等特点。

| Abstract: | Polysilicic acid containing aluminium ions (PSAA), a new flocculant, has been prepared by using sodium silicate, sulfuric acid and aluminium sulfate as raw materials. The properties of PSAA and the factors affecting treatment of wastewater were studied experimentally. The flocculating effect of PSAA was compared with that of polyaluminium chloride (PAC). The experimental results showed that the flocculating properties of PSAA was greatly influenced by the content of aluminium ion-in PSAA. When the molar ratio of A to SiO2 was equal to ane, the flocculating effect of PSAA was best. Compared with PAC, PSAA is a low cost, highperfor-mance water-reating agent. |
