- Respirometer was used to monitor microbial activity in activated sludge.
- Over 300 strains of bacteria have been found in activated sludge.
- The acclimated active sludge could degrade 78% of oil in 24h.
- Acetate was degraded by denitrifying activated sludge.
- We apply a new natural high efficiency of unchanged chitosan(VCG)to retreatment of city sewage,which was used after traditional activity sludge treatment.
- Changing rule and activity status of biological activity of activated sludge in SBR process were studied by the determination of TTC-ETS activity.
