英文摘要: The effects of the flocculant composed of autoclaved fly-ash brick and chitosan for algae Microcystis aeruginosa removal were investigated. The results showed that when 1 mL flocculant was added in 25 mL algae suspension, which initial density was 106 cells/mL, the removal rate of algae reached 88.4%. In order to enhance the removal efficiency, pre-oxidation with KMnO4 was studied. The results indicated that it could improve algae coagulation removal by 9.44% when it was pre-oxidized by KMnO4 with the concentration of 0.9 mg/L. The cells of M. aeruginosa sunk quickly, thus the algal cells were removed completely. In conclusion, the combined flocculant owns the advantages of low concentration, short reaction time, and could be employed for algae control. (C) 2015 Elsevier B.V. All rights reserved.
