Abstract: FIELD: removal of NOx from industrial waste, compounds, sewage. SUBSTANCE: invention presents single-stage method of NOx removal from industrial waste products, compounds and sewage. The method provides for using uniform reactionary container, in which superheated steam is used. If necessary it may be supplemented by oxygen for reduction of nitrogen oxides present in a broad set of organic compounds. Sweeping reduction occurs, when a blend steam / oxygen is injected in a air-fluidized bed consisting of ceramic grains. For reduction of nitrates up to nitrogen in the reactionary container they measure reducing additives and /or provide power supply. At the expense of speed of liquefying gas mixture grains are agitated, that further promotes collapse of solid wastes and promotes self-purification by means of attrition. As a result the availability of agglomerates is excluded and oxygen in case of its application, to some degree promotes oxidation of by-products of wastes and ensures additional way to keep the thermal conditions of the operation. EFFECT: invention allows to delete nitrogen oxides from industrial waste products unrestricted. 23 cl, 1 dwg
