| 摘 要： | 以硫酸铝、偏铝酸钠和硅酸钠为原料制备了新型絮凝型－－聚硅硫酸铝（ＰＡＳＳ）。通过絮凝实验讨论了ＰＡＳＳ的投加量、铝硅比、原水温度及ｐＨ值对絮凝效果的影响。实验结果表明，ＰＡＳＳ具有投加量小，适应的原水ｐＨ值及水温范围宽，形成絮体速度快，絮体粗大。与硫酸铝及聚合硫酸铝相比，ＰＡＳＳ具有更优越的絮凝除浊性能。

| Abstract: | A new type flocculant of polymeric silicate-aluminum sulfate (PASS) was synthesized with Al 2(SO 4) 3,Na 2SiO 3 and NaAlO 2.The effect of the dose,the molar ratio of Al/Si,pH and temperature of the water sample were discussed.The result of experiments indicated that PASS had the characters of less dose,wide pH range,wide temperature range,fast depositing,thick flocculate.Compared with Al 2(SO 4) 3 and polymeric aluminum sulfate (PAS),PASS was in advantageous position of the removing turbidity. |
