摘要

•Applicable technology for cyanobacterial bloom water treatment was investigated.•Cyanobacterial composition shift and biomass increase were observed after bloom events.•KMnO4 was used for source water pre-oxidation, but resulted in Mn(II) release.•Mn(II) was efficiently oxidized to Mn oxide during bioaugmented sand filtration.•KMnO4 pre-oxidation followed by bioaugmented sand filtration is applicable.
