Five types of biomass from MBBR, IFAS, and MBR were compared for the degradation of OSPW. MBBR and IFAS-biofilm showed high AEF and classical NAs removal, MBR-flocs showed high COD removal. NAs degradation was highly dependent on the carbon number and NA cyclization number according to UPLC/HRMS analysis. Denitrifiers were more abundant in suspended phase of activated sludge flocs.
