SUBSTRATE OF BIOMASS FOR NITRATION, REACTOR FOR PERFORMING AEROBIC NITRATION OF REFUSE BY USING SAID SUBSTRATE AND BIOLOGICAL METHOD FOR IT, AND METHOD FOR REMOVING NITROGEN COMPOUND

摘要

Biological process for aerobic nitrification of effluents. <??>According to this process the biomass is fixed on to a granular solid support acting as a substrate for the said biomass. <??>This process applies very particularly to the treatment of sewage with a view to removing ammoniacal nitrogen therefrom.
