| 英文摘要 | Polyaluminum coagulant with a content of 76.8% of Al-30 (PAC(Al30)) was prepared. Its coagulation behaviors were compared with high Al-13 content polyaluminum coagulant (PAC(Al13)) and AlCl3. The species stability was studied using Al-Ferron method and Al-27 NMR. The coagulation performances were investigated by studying the rate of flocs development, the turbidity removal efficiency and charge neutralization capacity under fixed pH conditions and uncontrolled pH conditions. The effect of pH on coagulation was also studied. The results show that PAC(Al30) are stable for using as coagulant. PAC(Al30) causes less pH depression than PAC(Al13). The charge neutralization capacity of PAC(Al30) is slightly lower than that of PAC(Al13) at pH >= 6.8 and higher at pH <= 6.5. PAC(Al30) achieves the most effective turbidity removal in these three coagulants. And it acts effectively within a much broader dosage range and a wider pH range when compared with PAC(Al13). PAC(Al30) achieves the highest turbidity removal due to its strong flocs formation capacity. The results verify that Al-30 is another highly active coagulation/flocculation species for turbidity removal. (c) 2006 Elsevier Ltd. All rights reserved. |
