In this study, sequencing batch operation was successfully combined with a pilot-scale anaerobic biofilm-modified anaerobic/aerobic membrane bioreactor to achieve ammonium oxidation (anammox) without inoculation of anammox aggregates for municipal wastewater treatment. Both total nitrogen and phosphorus removal efficiencies the reactor reached up 80% in 250-day operation, effluent concentrations 4.95 mg-N/L 0.48 mg-P/L. situ enrichment bacteria maximum relative abundance 7.86% observed biofilm, contributing 18.81% removal, denitrification being primary pathway (38.41%). Denitrifying (DPR) (40.54%) aerobic uptake (48.40%) played comparable roles removal. Metagenomic results showed that biofilm contained significantly lower abundances NO-reducing functional genes than bulk sludge (p < 0.01), favoring catabolism former. Interactions between flanking community were dominated by cooperation behaviors (e.g., nitrite supply, amino acids/vitamins exchange) network. Moreover, hydrolytic/fermentative endogenous heterotrophic (Dechloromonas, Candidatus competibacter) substantially enriched under which could alleviate inhibition complex organics. Overall, study provides feasible promising strategy enriching achieving partial mainstream as well DPR.
