Effect of temperature on characteristics of microorganisms in IMO-SBR

For the purpose of studying the effect of temperature on the characteristics of microorganisms in immobilized microorganism system,a biological strengthened process: IMO-SBR,which combined microorganism immobilization technology with SBR,was developed and used for nitrogen containing wastewater treatment.Through the comparative test between IMO-SBR and SBR with ordinary activated sludge,the effect of temperature on microorganism activity and nitrogen removal performance of immobilized microorganism system and free microorganism system was studied;and the differences of the two systems and the three reactors were compared.The results showed that: temperature had great influence on the nitrogen removal performance of microorganism;immobilized microorganism system could get good activity and nitrogen removal capability in a wild temperature range,which showed a better temperature tolerance ability than free microorganism.
