英文摘要	This study describes the development of a novel sludge wasting control strategy based on online oxygen uptake rate (OUR) measurements To automate energy use and carbon capture in high-rate activated sludge systems (HRAS). OUR-based wasting control has shown To directly manage the energy input to the HRAS system and resulted in stable carbon redirection. However, due to the highly dynamic conditions in HRAS systems, minimizing energy input within the HRAS system led to the rapid washout of sludge due to sudden loading changes (i.e. rain events) and/or operation under limited biomass inventory. Online bioflocculation limitation indicators based on the ratio of the maximum volumetric OUR in the contactor zone and stabilizer zone were developed within this study To optimize bioflocculation within HRAS system.
