| Abstract: | Most aerobic granules have been reported to be cultivated successfully in sequencing batch reactor (SBR). However, a granulation process was observed in a continuous-flow membrane bioreactor (MBR) fed with synthetic berberine wastewater. In order to investigate the process and mechanism of aerobic granulation in the continuous-flow MBR, the pollutant removal rate in the reactor and the properties of aerobic granular sludge were analyzed, and the aerobic granulation mechanism in the continuous-flow MBR was discussed. The formation of aerobic granular sludge enhanced the process stability and the shock-resistance of the MBR. Berberine stimulated the secretion of extracellular polymeric substances (EPS) from the microorganisms in the aerobic granules, and the stable selection pressure created by berberine caused the granulation and ensured the stability of the aerobic granular sludge. Berberine is considered to be the driving force for the aerobic granulation. This work hopefully provides a new explanation for aerobic granulation in a continuous-flow reactor. |
| Keywords: | aerobic granular sludge granulation continuous-flow membrane bioreactor berberine selection pressure |
