摘　　要：采用新型含锆聚合混凝剂对珠江原水进行混凝处理,同时与聚合氯化铝和硫酸铝比较混凝效果。结果表明:新型混凝剂在投加量为0.05 mmol/L时,浊度的去除率达到87%;进一步增大其投加量,浊度的去除率可达到96.3%以上;随着pH值的升高,浊度和UV254的去除率均先升后将;在pH值为4.4左右时,处理效果最优。新型混凝剂具有反应快、形成絮体大而密实、絮体沉降快、浊度去除率高等优点,是一种潜在的高效水处理药剂。A novel zirconium-containing polymeric coagulant was used to treat raw water from Pearl River, and its coagulation capability was compared with PAC and Al2（SO4） at the same time. The results showed that： when the dosage of the novel coagulant was 0.05 mmol/L, the removal rate of turbidity reached 87%, and with the increasing of the dosage, it could reach above 96.3%; along with the pH value increasing, the removal rates of turbidity and UV254 increased at first and then decreased; the best removal effect was achieved when the pH value was about 4.4. It could be seen that, the novel coagulant had advantages of fast reaction speed, forming big and dense flocs, fast sedimentation rate, high turbidity removal efficiency and so on, which could be used as an efficient water treatment agent in the future.
