Under effluent recirculation, algal-bacterial AGS exhibited better overall performance and stability over bacterial AGS, achieving averagely dissolved organic carbon (DOC), total nitrogen (TN) and total phosphorus (TP) removals of 40%, 60%, and 15% in comparison to 32%, 35%, and 10% by the bacterial AGS, respectively. More importantly, after being switched from effluent recirculation to intermittent aeration, the algal-bacterial AGS could quickly adapt to the change in operation conditions, clearly indicated by the recovered removals of DOC from averagely 40% to 100%, TN from 60% to 98%, and TP from 15% to 64% along with the improved sludge settleability and stability after 24 day operation. Energy consumption analysis also suggested that algal-bacterial AGS-based CFR systems may have more potentials for energy saving and stable performance under proper operation strategies. © 2019 Elsevier Ltd |
