In a post-anoxic sequencing batch reactor(SBR) system treating domestic wastewater, the realization of nitritation and denitrifying phosphorus removal by nitrite pathway and its removal efficiency was investigated. The results indicated that nitritation and denitrifying phosphorus removal in low concentration of ammonia water at room temperature was established by the strategy of sludge discharge in condition of limited oxygen. The effluent of COD、TP、NH4+-N、TN was 17.47mg/L,0.462mg/L,0mg/L and 8.35mg/L, respectively. According to batch experiments, the ratio of denitrifying phosphorus accumulating organisms which took nitrite as electron acceptor in total poly-phosphate accumulating organisms could reached 70%. Studies had found that 140mins anoxic reaction time could have negative effects on phosphorus removal, and anoxic reaction time should be controlled in the completion of the nitrite consumption. Aeration mode affected the removal of nitrogen. With total oxygen changeless, adopted the strategy of high to low strength aeration(1.2~0.2L/min), nitrogen removal efficiency could be improved.
