The characteristics of N<sub>2</sub>O emissions from an anaerobic/aerobic/anoxic (A/O/A) sequencing biofilm batch reactor (SBBR) were investigated under different influent COD/nitrogen (C/N) ratios (from 1-4). Results indicated that the C/N ratios affected the quantity of polyhydroxybutyrate (PHB) and residual organic substances after the anaerobic period, resulting in the largest N<sub>2</sub>O emission during aerobic period occurred at a C/N of 2. Moreover, during the anoxic PHB-driven denitri ...[more]
