Abstract

The present abstract relates to an invention patent for a closed-circuit mobile system for recovering contaminated soils, pertaining to the field of combating environmental pollution; said system comprising, essentially: 1)—a step of washing the contaminated soil SC (block 1), consisting essentially of removing the contaminated soil SC from the place of origin O and homogenizing same under high pressure with washing solution SLAV comprised of water+washing product PL containing modified terpenoids and/or terpenes; provided by compact washing equipment (1) installed close to the place of origin O of the contaminated soil SC where the recovered soil SR is backfilled; and 2)—a recovery step carried out using centrifugal clarifier (10) and centrifuge (20) (block 2), wherein recovered contaminants CR and recovered washing product PLR are produced, the latter being recycled to make up washing solution SLAV, and the recovered contaminants CR being reused in process P that originated same or other; said steps (1) and (2), process P which originated the contaminated soil SC, the means for providing washing solution SLAV, and the outlets for recovered soil SR from step (1) and for recovered contaminants CR and recovered washing product PLR from step (2) forming a closed circuit, which does not substantially produce disposable material(s).
