The present invention generally pertains to treatment cells, systems and methods for rehabilitating and valorizing a soil. More specifically, the present invention relates to methods for removing volatile compounds from the contaminated soils. The methods and system generally make use of an openable and reclosable rigid enclosure capable of receiving and treating many tons of soils. According to the invention, heated air is circulated through the soil to allow volatilization of the contaminants which can then be captured and separated from the circulating air before the air is re- heated and re-circulated through the soil.
La présente invention se rapporte de manière générale à des cellules de traitement, à des systèmes et à des procédés de régénération et de valorisation d'un sol. La présente invention se rapporte plus spécifiquement à des procédés destinés à retirer les composés volatils des sols pollués. Les procédés et le système utilisent généralement une enceinte rigide que l'on peut ouvrir et refermer et qui permet de recevoir et de traiter plusieurs tonnes de sols. Selon l'invention, de l'air chauffé circule à travers le sol pour permettre la volatilisation des agents polluants qui peuvent être ensuite capturés et séparés de l'air en circulation avant que l'air ne soit à nouveau chauffé et mis en circulation à travers le sol.
