Title (EN) METHOD OF TREATING CONTAMINATED SOIL FOR CONVERTING THE SOIL TO HARMLESS SOIL AND APPLICATOR
(FR) PROCEDE DE TRAITEMENT DE SOL CONTAMINE POUR LA CONVERSION DU SOL EN SOL INOFFENSIF ET DIFFUSEUR
Abstract: front page image
(EN)A method of treating a contaminated soil for converting the soil to a harmless soil, characterized in that it comprises covering the soil contaminated with a chemical substance having a boiling point of 500˚C or lower with an applicator, and irradiating the contaminated soil with a microwave, to thereby remove the chemical substance from the contaminated soil; and an applicator for use in the method. The method is practically applicable for converting a contaminated soil to a harmless soil in a short time and, in some cases, for converting a large amount of a contaminated soil to a harmless soil on the site at one standing.
(FR)La présente invention a trait à un procédé de traitement de sol contaminé pour la conversion du sol en sol inoffensif, caractérisé en ce qu'il comporte le recouvrement du soi contaminé avec une substance chimique présentant un point d'ébullition égal ou inférieur à 500 °C à l'aide d'un diffuseur, et l'irradiation du sol contaminé au moyen de micro-ondes, afin d'éliminer la substance chimique du sol contaminé. L'invention concerne également un diffuseur pour la mise en oeuvre du procédé. Le procédé est peut être utilisé pour la conversion rapide d'un sol contaminé en un sol inoffensif et, dans certains cas, pour la conversion d'une grande quantité de sol contaminé en un sol inoffensif in situ en une seule opération.
