Effect of anoxic to aerobic duration ratios on nitrogen removal and nitrous oxide emission in the multiple anoxic/aerobic process
Characteristics of nitrogen removal and nitrous oxide (N2O) emission in the multiple
anoxic/aerobic (AO) process were examined in three sequencing batch reactors (SBRs) with
different anoxic durations (50 min, SBRH; 40 min, SBRM; 30 min, SBRL) and a fixed aerobic
duration of 30 min. The highest total inorganic nitrogen removal percentage of 85.8% was
obtained in SBRH, while a minimum N2O emission factor of 1.9% was obtained in SBRL.
During nitrification batch experiments, the N2O emission factor and emission rate were both …
