| 摘要 |
The invention provides a method and a system for treating and/or decontaminating porous materials and/or aquifer layers, including at least one housing (1) including at least one heating module, one module for injecting pressurised liquid and one recovery module; heating means capable of being introduced in the porous material, said heating means including at least one heating tube (46) having a heat-conducting outer wall, said heating tube can be connected to the heating module; and at least one pressurised-liquid injection tube (41) that can be connected to the pressurised-liquid injection module; at least one vapour-extraction means (12) for extracting the contaminant vapour. Said extraction means is capable of creating the vacuum in the porous material and can be connected to the recovery module, and at least one layer (42) of sealing material that can be applied to the surface of the porous material to be treated. |
