초록

This study was performed by the airlift bioreactor using the nitrifier consortium entrapped in polyvinyl alcohol(PVA) for removing low concentration total ammonia nitrogen(TAN). At the aeration rate of 1.5 vvm, TAN removal rate and removal efficiency was 316.6${\pm}$7.2 $g/m^3$ day and 92.8${\pm}$2.2%. Removal rate was continuously increased with decreasing from 0.5hr to 0.05hr of hydraulic residence time(HRT), whereas removal efficiency was decreased with decreasing HRT.
