Abstract

a. L'invention concerne un procédé et un dispositif pour enlever l'azote des eaux résiduaires. b. Procédé caractérisé en ce qu'à la suite de l'installation de clarification mécano-biologique conduisant à l'oxydation de l'ammoniaque et à la réduction du nitrate donnant de l'azote gazeux, on utilise deux étapes de purification biologique se suivant directement ou indirectement et distincts l'un de l'autre, travaillant selon le procédé du lit bactérien plongeur, où les surfaces de croissance bactérienne de chaque type, qui plongent au moins à moitié dans l'eau résiduaire, sont décalées en rotation. c. L'invention trouve son application principale dans la technique se rapportant à la purification des eaux résiduairesat. The invention relates to a method and a device for removing nitrogen from waste water. b. Process characterized in that following the mechanical-biological clarification installation leading to the oxidation of the ammonia and the reduction of the nitrate giving gaseous nitrogen, two stages of biological purification following one another directly are used. or indirectly and distinct from each other, working according to the dipping trickling filter method, where the bacterial growth surfaces of each type, which are at least half immersed in the waste water, are rotated shifted. vs. The invention finds its main application in the art relating to the purification of waste water.
