[TTC-ETS activity monitoring of A2/O process for combined sewage treatment].
The influences of variations of temperature and F/M on the TTC-ETS activity have been experimentally studied. The correlation between TTC-ETS activity and COD degradation was also analyzed. Comparing TTC-ETS activities with physical and chemical indexes when high C/N ratio impacted A2/O process, the advantages and disadvantages of using TTC-ETS activity to characterize the status of A2/O process were illustrated. The results showed that both temperature and F/M were positively correlated with TTC-ETS activity. TC-ETS activity was in the range of 13.2-48.3 mg/(g x h) and the maximum value was 60 mg/(g x h) which had a significant relationship with COD removal rate. In this system, abnormal state was pre-warned by TTC-ETS activity. The highest removal rate of COD appeared when TTC-ETS activity was 41.0 mg/(g x h).
