| Abstract: | Denitrifying phosphorus removal bacteria was cultivated using nitrite as electron acceptor by period operation method in a sequencing batch reactor and nitrate and nitrite as electron acceptor on denitrifying phosphorus removal were compared.Results showed the method of anaerobic/aerobic + anaerobic/anoxic(instantaneous nitrate dosing) + anaerobic/anoxic/aerobic(instantaneous nitrite dosing)could screen and enrich denitrifying phosphorus removal bacteria using nitrite as electronic acceptor,with removal rate of PO43-up to 88.62%.With the concentration of electron acceptors dosage both at 25 mg/L,the rate of denitrification and phosphorus uptake with nitrite as electron acceptors was higher than the nitrate. |
