  • The ability of biological nitrogen and phosphorus removal by using synthetic wastewater was investigated in biomembrane two-sludge SBR system based on the theory of denitrifying phosphorus removal. Long-term experiments showed that biomembrane two-sludge SBR system could enable nitrobacteria and denitrifying phosphorus removing bacteria to obtain their own optimal conditions, thus solving the contradiction of nitrogen and phosphorus removal in conventional process. So the better nitrogen and phosphorus removal efficiency with less carbon source and power source was achieved. Under the condition of C∶N∶P being 25∶5∶1 and ratio of water exchanging 75%, the removal rates of COD, TP and NH+4-N were 89.13%, 96.12% and 86.78%, respectively.
