    Method and system for the autotrophic elimination of nitrogen in wastewater by biofiltration in a fixed bed. They achieve the elimination of nitrogen in an influent of wastewater with a nitrogen content less than 1500 mgntotal/l and a bod ratio5/notal of between 0.01 and 1 by an autotrophic anaerobic oxidation biofilm process in which the influent is passed through a biofilter in a fixed bed constituted by a set of granular particles colonized by aob bacteria and anammox bacteria, said granular particles having an effective size (d <sub > 10) between 2.0-8.0 mm and a minimum specific surface area of 800 m2/m3.

    Specifically, the system is considered to be applicable to wastewater with a nitrogen content of less than 1500 mg Total / L and a ratio of Organic Matter / Total Nitrogen, expressed in mgDBO5 / Total mg of between 0.01 and 1.
    Unlike the ANITATMMox system, the system of the invention is based on carrying out the process of autotrophic nitrogen removal by passing an influent with the characteristics mentioned by a fixed bed biofilter.
    In the embodiment illustrated in Figure 1, the system comprises:
    -A biological reactor 11 with a fixed bed biofilter 13.
    - A sub-system for feeding the biological reactor 11 comprising an influent reservoir 17 connected to the biological reactor 11 by a main pipe 19 and a piston pump 25 to drive the influent so that it crosses the biological reactor 11 from below to above. This subsystem will be provided with the necessary regulating valves in said pipe.
    -A reagent reservoir 21 (to control the influent's pH) connected to the main pipe 19 through a secondary pipe 23 and a piston pump 27 to drive the reagent.
    -A sub-system of effluent outlet resulting from the passage of the influent through the biological reactor 11 comprising an outlet pipe 29 with a siphon 31 in its initial part and an effluent reservoir 33.
    - A washing system of the fixed bed biofilter 13 comprising a washing pump 35 connected to the biological reactor 11 through a washing pipe 37 with a regulating valve.
    -Additional media, including an air compressor 41 and a safety valve
    43
    The fixed bed biofilter 13 comprises as a support a set of granular particles and as biological material AOB bacteria (initials of the English expression Ammonia Oxidizing Bacteria) and ANAMMOX bacteria. These bacteria colonize the surfaces of said granular particles and allow the autotrophic anaerobic oxidation process of the influent to be carried out.
