| 中文摘要 | In this study, the preparation of composite bioflocculants from compound bioflocculant (CBF) and poly-aluminum chloride (PACl) was investigated under different PACl/CBF ratios (v/v), basicities ([OH]/[Al] ratios) and polymerization approaches: the composite polymerization (PAClCBF) and the co-polymerization (PCBFACl). Fourier transform infrared (FTIR), Al-ferron spectrophotometry, scanning electron microscope (SEM) and zeta potentials studies were performed as well to characterize the composite bioflocculants. Finally, coagulation performance and floc properties of the composite bioflocculant in comparison with dual-coagulants were studied for treatment of kaolin suspension with different concentrations. From the results, interactions took place between Al species and CBF molecules, which lead to the formation of composite species. Significant improvement of coagulation efficiency was achieved by composite bioflocculants at PACl/CBF ratio ranging from 0.05 to 0.25 and basicity ranging from 1.1 to 1.7. PAClCBF appeared to be more efficient than PCBFACl owing to their higher Al-b content. Furthermore, composite bioflocculants was more preferred than dual-coagulants for treatment of kaolin suspension with lower concentrations (<50 mg/L). (C) 2012 Elsevier B.V. All rights reserved. |
