摘　　要：通过对蒙脱石壳聚糖复合絮凝剂进行正交实验,证明不仅二者对絮凝的效果产生极为显著的影响,而且二者的交互作用对絮凝的效果也有极为显著的影响。通过测量复合絮凝剂的Zeta电位,以及处理废水时的扫描电镜图,可以得知复合絮凝剂的电性和分子结构变化,可以初步推断出蒙脱石与壳聚糖在复合絮凝剂中的作用,以及二者交互作用产生的原因。This article through carries on the orthogonal experiment to the compound flocculant of Montmorillonite/Chitosan. The experiment proved, not only two have the remarkable influence to the flocculation effect, moreover the two correlation also has the extremely remarkable influence to the flocculation effect. Through to measure the Zeta electric potential of the compound flocculant and scan the electricity mirror chart when use the compound flocculant to deal with the waste water . We can initially infer the flocculation mechanism of the compound flocculant. Especially we can get the correlation reason between the Montmorillonite / Chitosan from the Zeta electric potential and molecular structure of compound.
