Study on the Cultivation and Enrichment of Denitrifying Phosphorus Accumulating Organism in Different Patterns

Abstract:

With synthetic domestic wastewater, denitrifying phosphorus accumulating organism was enriched and cultured by using activated sludge from a wastewater treatment plant in a set of sequencing batch reactor. Results showed that the system had a good effluent performance under the three-phase cultivation of anaerobic/aerobic, anaerobic/anoxic/aerobic and anaerobic/anoxic; the effluent concentration of chemical oxygen demand (COD) was below 25 mg/L, the average removal rate of phosphorus was 84.63%-88.19%.
