| Abstract: | A2N(anaerobic/anoxic/nitrifying) denitrifying phosphorus and nitrogen removal process is a new process developed based on the theory of phosphorus uptake by denitrifying phosphorus accumulating organisms under anoxic condition.The principle and the characteristics of A2N process was introduced,the influencing factors such as hydraulic retention time,dissolved oxygen,mass concentration of NO3-and NO2-,mass ratio between COD and TN in the raw water,volumetric exchange rate,effluent SS etc.were discussed and analyzed.The design ranges of the key influencing parameters of the process were proposed consulted with the study results in China and aboard. |
