PROCEDIMIENTO DE ELIMINACION DE NITROGENO POR VIAS ANAEROBICAS SOBRE SOPORTE PLASTICO

摘要

The invention relates to a method for the elimination of nitrogen from wastewater, comprising the following steps: a) partial nitrification of the ammonium by means of autotrophic ammonia-oxidising bacteria; and b) anaerobic elimination of the inorganic nitrogen from the water obtained in (a) by means of autotrophic anaerobic bacteria; said method being characterised in that the autotrophic ammonia-oxidising bacteria of step (a) and the autotrophic anaerobic bacteria of step (b) are in the form of a biofilm on a support; and in that steps (a) and (b) are carried out in different tanks.
