Variation of TTC-ETS Activity of Activated Sludge in SBR Process
Changing rule and activity status of biological activity of activated sludge in SBR process were studied by the determination of TTC-ETS activity. The results indicate that TTC-ETS activity can reflect effectively the biochemical reaction course of SBR process. Biological activity of organic matter biodegradation, nitrification and denitrification course in SBR process is reduced in order. Operational conditions cannot influence the changing rule of TTC-ETS activity, but the time of the appearance of break points marking different reaction course in profile and the average biological activity are influenced.
