| 摘 要： | 为降低饮用水中铝离子含量并提高浊度去除率,研制了一种新型自来水絮凝剂（简称PCMS）.该絮凝剂以聚合氯化铝铁（PAFC）、壳聚糖（CTS）和改性淀粉（MS）为主要组分,其配比为V（0.1wt%PAFC）∶V（0.001wt%CTS）∶V（3wt%MS）=25∶5∶7.在室温、中性条件下、絮凝剂投加量达到5 mg.L-1时,原水的浊度去除率可达98%以上,铝离子去除率可达67.3%.考察了絮凝剂投加量、搅拌时间、速度、温度、酸碱度等因素对其絮凝效果的影响.结果表明,絮凝剂的投加量对絮凝效果影响最大,其他因素则影响较小.相对于传统单一的絮凝剂如聚合氯化铝（PAC）、聚合硫酸铁（PFS）、硫酸铝等,PCMS投加量更小,处理效果更好,性价比更高.

| Abstract: | In order to reduce the turbidity and aluminum ion of Changjiang river, a novel coagulant has been presented in this paper, which is called PCMS. And the proportion of this coagulant is V（0.1wt% PAFC）：V（0.001wt% CTS）： V （3wt% MS） = 25：5：7. Operational conditions of neutral pH and room temperature allow up to 98% turbidity and 67.3% aluminum ion removal with 5 mg-L-1 of coagulant. Stirring intensity and mixing periods, temperature and pH are evaluated and they are found to be less influential than coagulant dosage. Compared with the single classical coagulant, PCMS is more efficient than PAC, PFS and aluminum sulphate and so on. |
