Direct and indirect effects of oxygen limitation on nitrification process applied to reject water treatment
Original language description
The direct and indirect influence of temporary oxygen limitation on the nitrification of reject water was investigated using a continuous stirred tank bioreactor operated for 330 d at laboratory temperature (23 ? 1°C). A decrease in dissolved oxygen (DO)concentration from 3 to 0.7 mg L-1 lasted for 38 d and led to effective nitrite accumulation?more than 95% of total oxidized nitrogen was present as nitrite. The drop of DO concentration, at the same time, caused a decrease in the nitrogen oxidation rate from 1.36 to 0.73 kgNm-3 d-1. After a subsequent DO concentration increase to 3 mg L-1, the nitrite accumulation remained stable for another 90 d. This development was caused mainly by the indirect effects of DO limitation, consisting especially in thechange of nitrogen species represented. A significant increase in free nitrous acid concentration induced by temporary DO limitation seems to be the key factor in this respect. The results of Fluorescence in situ hybridization analysis c
