FIELD: mining.
SUBSTANCE: method of territory reclamation involves contaminated site contouring by drainage ditches and receiving pits, accumulation of "reverse" emulsion from the site surface and partially from contaminated soil in pits, emulsion transportation from the pits to a treatment plant, emulsion separation in the treatment plant, and further usage. Next stage of site reclamation involves installation of perforated pipes in the partially decontaminated ground, and hot water is fed to the pipes under pressure. Emulsion washed out of soil is collected again at the receiving pits and transported to treatment plant, where it is decomposed by hot air aeration and vibration. Final stage involves biological reclamation of decontaminated soil.
EFFECT: reduced scope of excavation and transportation works, costs of oil-contaminated soil treatment and emulsion decomposition.
