| Abstract: | The modified and reversed A~2/O process is discussed in this article,also the nitrogen removal efficiency of it and the ratio of the sewage that going to the anaerobic and anoxic tank are analyzed.For urban waste water,the results show that:① The removal efficiency of nitrogen is 84.5% and the nitrogenous consistency of outlet is 6.2 mg/L.② The ratio that going to the anoxic and anaerobic tank should be no less than 37.2% to 62% and 40% respectively. |

| Keywords: | removal efficiency of nitrogen internal circulation reformed and reversed A~2/O process |
