Abstract

LA INVENCION SE REFIERE A LA EXTRACCION DE CONTAMINANTES CONSTITUIDOS DE METALES PESADOS Y DE ELEMENTOS TOXICOS CONTENIDOS EN DESECHOS CONSTITUIDOS POR LAS CENIZAS VOLANTES Y LOS RESIDUOS DE DEPURACION DE LOS HUMOS SALIENTES DE UN HORNO DE INCINERACION. LOS DESECHOS SON SOMETIDOS A ETAPAS DE CLORACION, DE TRATAMIENTO TERMICO,DE SULFATACION CON EL DOBLE OBJETIVO DE EXTRAER Y CONCENTRAR UNA FRACCION QUE CONTIENE LOS METALES PESADOS Y LOS ELEMENTOS TOXICOS.THE INVENTION IS RELATED TO THE EXTRACTION OF CONTAMINANTS CONSTITUTED OF HEAVY METALS AND OF TOXIC ELEMENTS CONTAINED IN WASTE CONSTITUTED BY FLYING ASHES AND WASTE PURIFICATION RESIDUES FROM AN INCINERATION FURNACE. WASTE IS SUBJECT TO STAGES OF CHLORINATION, HEAT TREATMENT, SULFATION WITH THE DOUBLE PURPOSE OF EXTRACTING AND CONCENTRATING A FRACTION CONTAINING HEAVY METALS AND TOXIC ELEMENTS.
