一种新型改性蒙脱石复合絮凝剂的制备及其应用研究

Study on Preparation and Application of A Novel Modifi ed Montmorillonite Composite Flocculant

利用价廉丰富的蒙脱石作为主要原料,制备出一种成本低、铝离子含量少、二次污染小的新型复合絮凝剂用于自来水的处理,取得了较好的效果。它与传统絮凝剂聚合三氯化铝(PAC)相比,其出水浊度和铝离子含量分别下降了9.5%和53.1%,降低药剂成本约9.5%,具有明显的经济与环境效益。

A novel composite flocculant with low-cost, less aluminum and less secondary pollution was made from montmorillonite that is a kind of cheap and abundant materials in our country. This flocculant can efficiently treat tap water. Compared with traditional flocculant such as PAC, the turbidity of effluent and the concentration of aluminum ion of exit tap water were respectively descended by 9.5% and 53.1%, and the cost of this flocculant was reduced by 9.5%. So this novel flocculant is of obviously economical and the environmental benefits.
