摘　　要：In order to further explore the mechanism of denitrifying phosphorus removal,the growth characteristics and denitrifying phosphorus removal characteristics of a typical denitrifying phosphate accumulating bacteria(DPB) which was isolated by previous experiment were studied.The effect of different electron acceptors on the efficiency of nitrogen and phosphorus removal was investigated by pure bacteria and reactor statics simulation tests.The growth curve of the DPB was typical,and its incubation period was less than 1 h and the logarithmic phase about 14 h.The result showed that the stain could utilize both nitrite and nitrate as different electron acceptors to take up phosphorus.And there was a good linear correlation between P removal and NO-3-N removal during phosphorus removal process.The sensitivity to nitrite of the strain was low.The effect of electron acceptors on phosphorus removal was not significant.The efficiency of removal for phosphorus and the nitrate was both above 60%,and that for nitrite was 100%.In order to further explore the mechanism of denitrifying phosphorus removal,the growth characteristics and denitrifying phosphorus removal characteristics of a typical denitrifying phosphate accumulating bacteria（DPB） which was isolated by previous experiment were studied.The effect of different electron acceptors on the efficiency of nitrogen and phosphorus removal was investigated by pure bacteria and reactor statics simulation tests.The growth curve of the DPB was typical,and its incubation period was less than 1 h and the logarithmic phase about 14 h.The result showed that the stain could utilize both nitrite and nitrate as different electron acceptors to take up phosphorus.And there was a good linear correlation between P removal and NO-3-N removal during phosphorus removal process.The sensitivity to nitrite of the strain was low.The effect of electron acceptors on phosphorus removal was not significant.The efficiency of removal for phosphorus and the nitrate was both above 60%,and that for nitrite was 100%.
