Abstract :
A novel modified sequencing batch reactor was proposed to treat municipal wastewater. The modified SBR had a special structure consisting of 4 tanks with different anaerobic/anoxic/aerobic function. A pilot-scale modified SBR process was researched to treat urban wastewater. The effluent TN was 10 mg/L. The TN removal efficiency was 58%. The NH4+-N removal efficiency was 98%. The average effluent NH4+-N was lower than 0.8 mg/L. The result showed the novel modified SBR was advantageous for nitrification bacteria growth. The TP removal efficiency was 81%. The average effluent TP concentration was less than 0.75 mg/L. The effluent TP concentration below 0.75 mg/L was got on 95% of the operational days. The result showed the novel modified SBR was advantageous for PAO bacteria growth.
