摘      要：In this study,nitrogen removal performance of the denitrifying ammonium oxidation(DAO)process was investigated when treating sulfamethoxazole(SMX)-laden secondary wastewater *** influent SMX concentration showed negligible effect on efficiencies for removal of nitrate and ***,the ammonium ions removal rate was moderately reduced,when the influent SMX concentration in wastewater reached 6 mg/*** nitrogen removal efficiency remained as high as 76.77%towards the day 158 at the end of ***_Brocadia and Candidatus_Kuenenia were the functional anammox *** unclassified_f__Rhodobacteraceae *** predominant heterotrophic denitrifying strain in the studied *** concentrations of soluble extracellular polymeric substances in sludge obviously increased from 16.76 mg/g VSS to 32.31 mg/g VSS,which might protect the nitrogen removal strains from high-concentration *** result provides a theoretical and technical foundation for the application of denitrifying ammonium oxidation process in treating sulfamethoxazole-laden secondary wastewater effluent.
