摘要

•Novel EPDA/PSR process without aeration was established for wastewater treatment.•Effluent TIN and phosphate reached 0.1 mg/L and 0 without external carbon dosage.•Fermentation by Candidatus Phosphoribacter led to sludge reduction in EPDA/PSR.•Amino acids as intracellular carbon storage were associated with P metabolism.•Transcriptional community composition reflected the actual operation state.
