中文摘要	A process consisting of anaerobic-aerobic-anoxic units was proposed to achieve shortcut nitrification removal with domestic wastewater at normal temperature. Effect of DO and FA on nitrite accumulation was investigated. DO was the main factor in partial nitrification. The steady nitrite accumulation was obtained when the DO was controlled at 1.5~2.5mg/L in the first aerobic compartment and 0.5~1.0 mg/L in the second aerobic compartment, while the ammonia removal efficiency was above 90% in this system. The analysis of microbial community of ammonium-oxidizing biomass using T-RFLP method showed that the preponderant microbe in this partial nitrification was Nitrosomonas oligotrophia cluster.
