摘要

•A novel RSABR was developed for decentralized wastewater treatment.•Achieved 62.5% SND ratio in a single reactor with no aerator.•Effluent COD, NH4+-N and TN were below 20, 0.4 and 15 mg/L, respectively.•The higher μmaxNO3 closely associated with denitrification efficiency.•Nitrification and denitrification were main metabolism pathways according to KEGG.
