Abstract

This study estimated the effect of influent TAN concentration. temperature and pH in the airlift bioreactor(aeration rate; 1.5 vvm, HRT 0.35hr) using immobilized nitrifiers by PVA. At the effect of influent TAN concentration, removal rate was increased with increasing it and removal efficiency maintained 93${\pm}$2%. The optimum temperature for nitrification was $30^{\circ}C$ and at this point. removal efficiency was 95.5${\pm}$1.5%. It was effective to nitrify at $10^{\circ}C$ of low temperature. In the pH range from 7 to 9 in the bioreactor. removal rate and removal efficiency was 310${\pm}$10 $g/m^3$ day and 94${\pm}$3%.
