| 英文摘要 | A comparative study on zone 2 coagulation between polyaluminum chloride (PACl) and cationic polyelectrolytes was conducted by applying a sensitive monitoring technique coupling with the conventional jar test. The effect of coagulant dosage and mixing were examined. The experimental results show that there exists both difference and similarity of coagulation between PACl and cationic polyelectrolytes. Being molecularly small, coagulation with PACl is achieved typically through adsorption charge-neutralization mechanism. Only PACl25 with presence of large particle size species, Alc, does an electrostatic patch effect appear. However, the mechanism of coagulation with cationic polyelectrolytes is both through charge neutralization and patch coagulation. The effect of electrostatic patch is increased with the increase of molecular size. Mixing exhibits a similar effect both on PACl and cationic polyelectrolytes after dosing, while floc breakage and regrowth is different significantly depending on the coagulant applied. |
