아질산성 질소의 축적에 대한 용존 산소와 free ammonia의 영향 연구

Abstract
For an integrated nitrification-denitrification process, nitrite formation in the aerobic stage leads to big savings. Dissolved oxygen concentration, temperature, pH and free ammonia concentration have been meet for nitrite accumulation. Also their effects over the ammonia oxidizers and nitrite oxidizers have been studied. Dissolved oxygen limitation and free ammonia inhibition led to slow nitrification and nitrite build up. In this study batch kinetics of ammonium and nitrite oxidations were performed with free ammonia accumulated nitrifiers. From the results it is likely the nitrite oxidizers are inhibited by oxygen limitation rather than free ammonia.
