Abstract

PURPOSE: To carry out stable and continuous denitrification treatment of wastewater by circulating a part of the water which is treated for denitrification to flow in the vicinity of the upper surface of a fluidized bed of carrier particles having supported denitrification bacteria thereon, thereby removing excessive bacteria cells together with air bubbles peeled off from the carrier particles.
