Soil decontamination method |
| abstract |
A method of decontaminating soil is described. The soil is crushed in a crusher (7), screened on a screen (3), fed to an agitator (17), mixed with an aqueous ammonia solution from a holding tank (13), then settled in a settling tank (19) and finally separated in a centrifuge (23) to obtain an aqueous ammonia solution containing the contaminant and the solid decontaminated soil to be returned to the site. The contaminated ammonia solution is extracted in a liquid/liquid extractor (25) to obtain an aqueous ammonia solution, which is recycled by a conduit (41) to the holding tank (13), and a solution of the contaminant in the solvent in stream (45) which is further concentrated in a still (29) to obtain a concentrate containing the contaminated waste. |
