| titleOfInvention | PROCESS FOR THE REHABILITATION OF POLLUTED SOILS BY TRIPLE PHASE EXTRACTION |
| abstract | The invention relates to a process for the rehabilitation of polluted soils of medium or low permeability, characterized in that it comprises a treatment of the ground by a triple-phase extraction process of simultaneous pumping of the gases contained in the vadose zone, of the pollutants. supernatants and groundwater. In the upper vadose zone 1 the gas circulates, zone 2 consists of supernatant liquids that must be removed, zone 3 is the upper part of the aquifer, and contains dissolved components which must be extracted, and zone 4 consists of unpolluted water. According to a preferred embodiment, needles of small diameter are used which make it possible to optimize their radius of influence and to adapt it to the characteristics of the terrain. The flow rate obtained with vacuum pumping is 10 to 20 times greater than that of conventional pumping. |
