比较了聚硅氯化铝（ＰＡＳＣ） 和聚合氯化铝（ＰＡＣ） 处理各种地表水的混凝效果，结果表明，ＰＡＳＣ 较ＰＡＣ具有更好的混凝效果。制备工艺和ＡｌＳｉ 摩尔比对ＰＡＳＣ 的混凝效果有影响，在相同ＡｌＳｉ 摩尔比下，共聚法制备的ＰＡＳＣ（ 共） 的混凝效果优于复合法制备的ＰＡＳＣ（ 复） 。对ＰＡＳＣ（ 共） 而言，在一定的ＡｌＳｉ 摩尔比范围内其比值越小，混凝效果就越好。但对ＰＡＳＣ（ 复） 而言，只有具有合适ＡｌＳｉ 摩尔比的产品其混凝效果最好，比值过高或过低，其混凝效果下降。与ＰＡＣ相比，温度对ＰＡＳＣ的混凝效果影响较小。
A comparison of the coagulation effects of polysilicic chloride aluminum chloride (PASC) and polyaluminum chloride (PAC) on various surface waters shows that PASC has a better coagulation effect than PAC. The preparation process and AlSi molar ratio have an effect on the coagulation effect of PASC. Under the same molar ratio of AlSi, the coagulation effect of PASC prepared by copolymerization is better than that of PASC prepared by composite method. For PASCs (co-), the smaller the ratio of AlSi molar ratio, the better the coagulation effect. However, for the PASC (replica), only the products with a suitable molar ratio of AlSi have the best coagulation effect. The ratio is too high or too low, and the coagulation effect is reduced. Compared with PAC, the temperature has little effect on the coagulation effect of PASC.
