CANON reactor performance and microbial community shifts with elevated COD/N ratios under a continuous aeration

Yao Zhang, Yayi Wang, Yuan Yan, Haicheng Han, Min Wu

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.
