| 摘 要： | 采用纳米SiO2超细粉末、FeCl3和聚合氯化铝(PAC)强化混凝去除海水中的腐殖酸。结果表明,FeCl3和PAC复配,使铝系絮凝剂良好的分散性与铁系絮凝剂优良的沉降性得到了较好协同效果,浊度和腐殖酸的去除率均好于两者单独使用。两者最适宜配比为:m(Fe)/m(Al2O3)=2,投加超细粉末强化混凝,浊度和腐殖酸的去除率分别可以达到94%和95%,并可以有效地改善絮体的沉降性能,缩短沉淀时间,使絮体和水体分离的更为彻底,水体上部几乎无悬浮物,对进水温度和pH值的适用范围广。

| Abstract: | This study was about to remove humic acid from seawater by enhanced coagulation with micro-size materials SiO_2,FeCl_3 and PAC.The results showed that the removal rates of turbidity and humic acid by mixed FeCl_3 and PAC were more efficient than they were used respectively.With the optimum ratio m(Fe)/m(Al_2O_3)=2 and micro-size materials,the removal rates of turbidity and humic acid were increased to 94% and 95%,respectively.The sedimentation time was shortened and the floccule could be separated from the ... |
