摘要

以硅酸钠、无水氯化钙、硫酸铝、羧甲基纤维素钠作为原料,在最佳条件出制备出聚硅酸铝钙-纤维素复合型絮凝剂(PSiAlCa-CMC),然后用其来处理模拟的松花江水样。将此絮凝剂投加到模拟松花江水样中,探究应用条件对絮凝效果的影响。结果表明,投加量为2.0 ml/L、絮凝时间为20 min、搅拌速度为100~140 rpm、水样温度为15℃~20℃、pH为5~6时,制备的PSiAlCa-CMC复合型絮凝剂对模拟松花江水样的絮凝效果良好,色度均到达98%以上,浊度均达到92%以上,结果表明,我们得到的絮凝剂成功絮凝水中杂质,色度、浊度去除率显著,适用于松花江水的絮凝处理。

Abstract:

Using sodium silicate, anhydrous calcium chloride, aluminum sulfate and sodium Carboxymethyl cellulose as raw materials, polyaluminum calcium silicate cellulose composite (PSiAlCa-CMC) flocculant was prepared under the optimum conditions, and then used to treat the simulated Songhua River water sample. The flocculant was added to the simulated Songhua River water sample to explore the effect of application conditions on flocculation efficiency. The results show that when the dosage is 2.0 mL/L, the flocculation time is 20 min, the stirring speed is 100~140 rpm, the temperature of water sample is 15~20 ℃, pH is 5~6, the PSiAlCa-CMC flocculant has the best flocculation effect. The flocculation effect of cellulose compound flocculant on simulated Songhua River water sample is good, the chromaticity is above 98% and the turbidity is over 92%. The results show that the flocculant successfully flocculates impurities in water and can be applied to sewage treatment in practice.
