NITRIFYING BIOMASS SUPPORT, BIOLOGICAL AEROBIC NITRIFICATION REACTOR AND PROCESS FOR TREATING WASTE WATER

摘要

The invention relates to an aerobic biological nitrification reactor for effluents containing NH4 + ions, characterized in that the nitrifying biomass is fixed on a support in granular form which acts as a substrate for the biomass, and in that the nitrification takes place. made in a stirred or fluidized bed. The invention also relates to a biological process for aerobic nitrification of effluents. This process is particularly applicable to the treatment of wastewater with a view to removing ammoniacal nitrogen therefrom.
