Frontiers of Environmental Science & Engineering 2014, Volume 8, Issue 4,   Pages 589-597 doi: 10.1007/s11783-013-0571-7

Abstract: The N O production in two nitrogen removal processes treating domestic wastewater was investigated inphase, the nitrogen conversion to N O gas was 27.7% and 36.8% of loss for conventional biologic N-removalprocess and short-cut biologic N-removal process.Higher nitrite accumulation resulted in higher N O emission in the short-cut nitrogen removal processPulse-wise addition of 20 mg gave rise to 3-fold of N O emission in the conventional N-removal process
