| Abstract: | Aerobic granular sludge obtained from SBR was used to treat simulated wastewater. Internal aerobic - facuhative anaerobic - anaerobic micro environment of the aerobic granular sludge was optimized. The removal efficiency of nitrogen and phosphorus was studied at different stage of the reactor and optimized condition of the system. By optimizing sludge settling time and aeration pattern, rapid sludge granulation can be achieved. The impact of sludge discharging method toward reactor stability was also discussed. Simultaneous removal of nitrogen and phosphorus was realized by means of function bacteria gathering. |
