使用连续光学监测技术研究了使用硫酸铝（“明矾”）、聚合氯化铝和阳离子聚电解质快速混合对絮凝体形成、破碎和重新形成的影响。对于铝基混凝剂，发现快速混合时间较短，形成较大的絮凝体，但在所有情况下仅发生有限的再生长，表明絮凝体破碎过程具有显着的不可逆性。对于阳离子聚电解质，絮凝体的再生长发生的程度要大得多，并且随着快速混合时间的延长，絮凝体的破裂几乎是完全可逆的。絮体破碎前和重新形成后的残余浊度值与动态监测结果一致。 (C) 2004 年化学工业学会。
The effect of rapid mixing on floc formation, breakage and re-formation using aluminium sulfate ('alum'), polyaluminium chloride and a cationic polyelectrolyte were investigated using a continuous optical monitoring technique. For the aluminium-based coagulants it was found that, with shorter times of rapid mix, larger flocs were formed, but only limited re-growth occurred in all cases, indicating a significant irreversibility of the floc break-up process. For cationic polyelectrolytes, the re-growth of flocs occurred to a much greater extent and with longer rapid mix times floc breakage was almost fully reversible. Residual turbidity values before floc breakage and after re-formation were consistent with the dynamic monitoring results. (C) 2004 Society of Chemical Industry.
