| Abstract: | phosphorus removal characteristics under three different electron acceptor conditions, i.e., oxygen, nitrate and mixtures of nitrate and oxygen in SBR system were studied. The experimental results showed that electron acceptor utilized by PAO was related to its occurrence;PAO replacing oxygen as electron acceptor through utilizing nitrate could realize denitrifying dephosphrus; denitrifying dephosphorus was stable metabolic behavior. |

| Keywords: | PAO denitrifying dephosphorus electron acceptor EBPR |
