Effect of the addition of organic carbon sources on nitrous oxide emission in anaerobic-aerobic (lowdissolved oxygen) sequencing batch reactors

Hongjing LI, Xiurong CHEN, Yinguang CHEN

Frontiers of Environmental Science & Engineering 2010, Volume 4, Issue 4,   Pages 490-499 doi: 10.1007/s11783-010-0248-4

Abstract: The effect of additional organic carbon sources on the production of nitrous oxide (N O) in anaerobic-aerobic(low dissolved oxygen) real wastewater treatment system was investigated.(low dissolved oxygen, 0.15–0.45 mg·L ) configuration.Off-gas analysis showed that N O was emitted into the atmosphere during the aerobic (low dissolved oxygen(low dissolved oxygen) system.
