Abstract

The denitrifying phosphorus removal bacteria (DPB) were enrichment using SBR reactor and two stages of training method under the low carbon source with nitrate as electron acceptor. The system was operated under the condition of anaerobic-aerobic-precipitation-discharge for 10 cycles in the first stage, and the condition of anaerobic-aerobic-anoxic-aerobic -precipitation-discharge were used for 40 cycles in the second stage. Results showed removal rate of PO43 -P , NH4+-N and COD was 95% ,80% and 90% when the effluent concentration was below 0.4mg/L, 3mg/L and 20mg/L respectively, which indicated that enrichment and cultivation of DPB in a set of SBR was feasible.
