摘要
对凹凸棒分别进行热改性、酸改性和酸-热共改性获得改性产品,然后以PAC为絮凝剂,改性凹凸棒为助凝剂进行给水中腐殖酸凝聚沉降处理,实验发现投加凹凸棒有助于改善絮凝体结构,提高其沉降性能。
The article modifies attapulgite with heat, acid, and heat-acid respectively.,then using PAC as flocculants, the modified attapulgite as coagulant for treating humic acid dissolved in drinking water. The result shows that attapulgite can improve the structure of flocculating constituent and increase the effect of settlement.
