文摘

Nitrified effluent recycled to the middle of ABR avoided inhibition on methanogenesis. ABR created distinct zones along the length of reactor for different processes. SCOD and TN removal was enhanced by increasing recirculation ratio. Insufficient carbon for denitrification can be supplied by step-feeding. Various reduced sulfur could be involved in autotrophic denitrification.
