P(DMC-AM)阳离子絮凝剂的絮凝性能研究

Study on the Capability of Cationic Flocculant P(DMC-AM)

对P(DMC AM)的絮凝条件、P(DMC AM)与不同种类的絮凝剂的絮凝性能比较和不同工业废水的絮凝处理效果比较等方面进行了研究 .实验结果表明 ,P(DMC AM)的最佳絮凝条件为 :[η]=70 0～ 80 0mL g,用量为 1.5～ 3.0mg L ;在电荷密度较大 ,分子量较大的各类有机污 (废 )水体系中 ,CODCr的去除率可达6 5 %～ 90 % ;P(DMC AM)絮凝性能优于聚合硫酸铁、聚碱式氯化铝和PAM等常用絮凝剂 .

The article studies flocculent condition of P(DMC AM) and compares the flocculent capability of different flocculants and the treatment effect of flocculating different industrial waste water. The results of experiments state that the best condition of flocculant P(DMC AM)is =700～800 mL/g,dosage 1.5～3.0 mg/L; the cleaning percentage of COD Cr in all kinds of organic waste water, which have great electronic charge density and great molecular weight, amounts to 65%～90%; and the flocculent capability of P(DMC AM) is better than common flocculants such as P[Fe x (SO 4) y ],P[Al(OH) x Cl y ] and PAM etc.
