| Abstract: | The selection and dominance of denitrifying phosphate accumulating organisms (DNPAOs), which are capable of utilizing nitrate as electron acceptor, was investigated in a laboratory-scale Sequencing Batch Reactor (SBR). The results obtained demonstrated that DNPAOs were already present in the conventional biological phosphorus removal system. The proportion of DNPAOs increased from 15.5% to 73% of total phosphate accumulating organisms after three phase selection. Simultaneous anoxic phosphate uptake and biological denitrification with good performance could be obtained in the anaerobic/anoxic SBR operated in steady-state. The concentration of phosphorus at anoxic end was low than 1?mg/L and phosphorus and nitrate removal efficiency were above 94% and 95% respectively. |
| Keywords: | Denitrifying phosphorus removal anoxic phosphorus uptake biological phosphorus removal nitrate |
