The Different Metabolic Activity of Activated Sludge Samples Taken from Reversed A2/O process and Conventional A2/O Process
The metabolic activity of sludge samples taken from two pilot scale activated sludge reactor was studied. The two reactors were of the same size and structure. One was operated according to the reversed A2/O process (R-reactor) and another was operated according to conventional A2/O process (Creactor). The activities of dehydrogenase (DHA) and electron transport system (ETS) and the specific oxygen uptake rate (SOUR) of sludge taken from Rreactor were 34.98%, 22.44% and 12.70% higher than those of the sludge taken from C-reactor. As for the R-reactor, the sludge undergoes aerobic condition right after anaerobic experience. Compared to entering aerobic stage from anoxic stage (C-reactor), entering aerobic stage from anaerobic stage can significantly enhance the activity of microbes, accelerate the decomposition of organics and improve the SOUR of the sludge.
