摘　　要：对脱乙酰多糖的絮凝特征作了研究．实验结果表明，脱乙酰壳聚糖属于阳离子型絮剂，用量过多则产生絮凝恶化现象．它适合于酸性和中性的水和废水处理．温度升高和静置沉降时间延长有利于提高絮凝效果，电解质则对絮凝效果有影响．The flocculation chacteristic of chitosan is described. The chitosan is a kind of cationic agglomera-tive agent.The flocculation deterioration is found when the excessive chitosan is added,The reeultsshow that this agglomerative agent is suitable for the treatment of acid and neuteral waste water;Thehigher temporature and longer standing time favor the focculatiun reeult and the effect of electrolyte onthe flocculation is also found.
