Abstract
La présente invention concerne un procédé d'assainissement de sol et d'eaux souterraines contenant des contaminants ayant une densité inférieure à 1g/cm³, tels que des hydrocarbures. La présente invention propose un procédé de nettoyage de sol contaminé sur la base d'une technologie de désorption thermique in situ. Les zones contaminées sont chauffées aux températures requises pendant le temps nécessaire pour vaporiser les composés volatils et semi-volatils. La technologie d'écumage se concentre sur la récupération de la couche flottante. La présente invention traite de la combinaison de désorption thermique et d'écumage in situ afin de traiter toutes les couches présentes dans le sous-sol et d'optimiser le temps de traitement de la zone saturée en chauffant le contaminant et en le rendant ainsi plus mobile.
