Abstract:Inhibitors were used to investigate the sources of the N2O emission from anoxic-aerobic biological wastewater treatment process. Results showed that during the anoxic phase, nitrate ammonification was the major source of N2O while denitrification turned out to be the sink of N2O. During the aerobic phase, nitrifier denitrification was the major source of N2O emission at medium aeration rate (65L/h), while both coupled nitrification-denitrification and nitrifier denitrification were responsible for N2O emission at lower or higher aeration rates, with the former performed as the major source.
