| Abstract: | Pre-hypoxia pool of improved A2/O process is good at the nitrogen removal,with nitrogen removal in the prehypoxia pool accounting for 15.11% of nitrogen removal in the whole system. By the material balance of nitrogen in the prehypoxia,anaerobic ammonium oxidation (ANAMMOX) which is confirmed and is possible in improved A2/O process is useful for the reconstruction of wastewater treatment plant,with energy saving and cost effectiveness. |
