Characterization of CANON reactor performance and microbial community shifts with elevated COD/N ratios under a continuous aeration mode
Next Previous
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.
