为了研究总硬度对铝形态混凝效果的影响，采用常规铝盐（AlCl 3）、聚合氯化铝（PAC-1）和纯化聚合氯化铝（PAC-2）3种铝混凝剂处理腐殖酸（HA）和高岭土。通过对不同总硬度的人工合成水进行混凝处理，研究了混凝效果和混凝动力学。结果表明，总硬度对铝盐混凝效果有影响。AlCl 3、PAC-1和PAC-2的混凝效率随着总硬度的增加而增加。混凝动力学研究表明，铝盐混凝过程中总硬度影响絮体的聚集。总硬度越高，在所有情况下反应时间越长。AlCl 3、PAC-1和PAC-2的最大絮凝体尺寸分别出现在总硬度达到8、4和1 mmolL −1时。
In order to investigate the effect of total hardness on coagulation efficiencies of Al species, different Al coagulants – conventional Al salt (AlCl3), polyaluminum chloride (PAC-1) and the purified polyaluminum chloride (PAC-2) – were used to treat humic acid (HA) and kaoline clay in this study. The coagulation efficiency and coagulation kinetics were investigated by treating synthetic water with different total hardness. The results suggest that total hardness can influence the coagulation efficiencies of aluminum salts. The coagulation efficiency of AlCl3, PAC-1 and PAC-2 increased when total hardness increased. The investigations on coagulation kinetics showed that total hardness influences the flocs aggregation in the coagulation process of aluminum salts. Higher total hardness results in longer reaction time in all cases. The maximum floc size of AlCl3, PAC-1 and PAC-2 occurs when total hardness reaches 8, 4, and 1mmolL−1, respectively.
