| Abstract: | There exist big differences on the characteristics and optimal metabolic condition of microorganisms in the processes of dephosphorization and desulphurization, so it is hard to reach the coordinated and stable operation in the same process. Based on the traditional microhiological dephosphorization techniques, A^2/O denitrifying dephosphorization technique has been newly found out and especially some introductions are made to phosphorus removal rules under anaerobic condition, the removal efficiency of phosphor under condition of meager oxygen and the change of nitrogen in oxygen shortage stage when NO3^- is regarded as the final electronic receptor in the oxygen shortage stage of A^2/ O denitrifying dephosphorization process. |
| Keywords: | denitrifying action electronic receptor biological dephosphofization nitrate |
