Frontiers of Environmental Science & Engineering 2019, Volume 13, Issue 1, doi: 10.1007/s11783-019-1095-6

Abstract:

COD/N at low ratios (0–0.82) improved N removals of CANON.

CANON performance decreased after COD/N up to 0.82.

The relative abundance of AOB decreased continuously with increasing COD/N.

AOB outcompeted at a high COD load led to CANON failure.

The relative abundance of AnAOB decreased and increased with increasing COD/N.

Production of N

Youkui GONG,Yongzhen PENG,Shuying WANG,Sai WANG

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 in laboratory-scale aerobic-anoxic sequencing batch reactors (SBRs). Results showed that N O emission happened in the aerobic phase rather than in the anoxic phase. During the aerobic phase, the nitrogen conversion to N O gas was 27.7% and 36.8% of loss for conventional biologic N-removal process and short-cut biologic N-removal process. The dissolved N O was reduced to N in the anoxic denitrification phase. The N O production rate increased with the increasing of nitrite concentration and ceased when oxidation was terminated. Higher nitrite accumulation resulted in higher N O emission in the short-cut nitrogen removal process. Pulse-wise addition of 20 mg gave rise to 3-fold of N O emission in the conventional N-removal process, while little change happened with 20 mg was added to SBR1.
