초록
This study was carried out to investigate the effects of hydraulic backwash load and porous ceramic media on the biological nitrogen removal efficiencies of a biological aerated filter. An upflow anoxic-oxic biological aerated filter(AO-BAF) with porous ceramic media can remove nitrogen by nitrification and denitrification in single unit. After the AO-BAF backwash, nitrogen removal efficiency was lowest and gradually increased to the steady state. Nitrification efficiency, however, showed the opposite result. It is likely that the biofilms are exposed to aerobic condition as the excess biofilms were sloughed off by backwashing
