| 摘 要： | 研究对比了Al13、不同碱化度的聚合氯化铝(PACl)及工业聚合氯化铝等去除水中腐殖酸的絮凝特征，从Zeta电位、RT(余浊)、UV254等角度分别考察了pH值和投药量的影响，对不同形态组成絮凝剂的混凝效能有了进一步明确的认识，并且对Al13的絮凝机理进行了有益的探索．结果表明，Al13是混凝过程中的优势形态，决定着混凝剂的电中和能力．

| Abstract: | The mechanism of humic acid removal by coagulation with Al_~13 , laboratory-made PACl and industry PACl was compared. Special attention has been paid on the aspects of different coagulation species. The influence of pH and dose was discussed respectively from the change of zeta potential, residue turbidity, and UV_~254 .The ~results show that the Al_~13 is the dominant and important species in the coagulation process deciding the charge neutralization ability. |
