Method for deodorization of flue gas during treatment of urban or industrial waste water purification, involves circulating flue gas through layer of filtering medium having blast-furnace slag, and watering filtering medium
The method involves circulating flue gas (102) through a layer of filtering medium (107) having a blast-furnace slag, and watering the filtering medium by pouring water on the surface of the layer of the filtering medium, where the water contains nutritive elements. The filtering medium is sown with microorganisms, where circulation of the flue gas through the filtering medium lies between 150 and 1000 meters per hour. An independent claim is also included for a device for treatment of flue gas comprising a reactor.L'invention concerne un procédé de désodorisation d'un effluent gazeux, comprenant une étape de mise en circulation dudit effluent gazeux (102, 202) à travers au moins une couche d'un média filtrant (107, 210) comprenant du mâchefer, et une étape d'arrosage dudit média filtrant (107, 210).
