FIELD: environmental protection.
SUBSTANCE: invention relates to environmental protection. Method of reducing oil-containing soil by chemical treatment involves mixing soil with calcium oxide and an acidic agent which forms with calcium oxide water-insoluble compounds. Process of oil-containing soil recovery with extraction of hydrophilic soil with preset pH values is performed by adding to soil calcium oxide and aluminum sulphate (Al2SO4*18H2O) with the following ratio of components: 1:1.33:5.33<Oil:CaO:Al2SO4*18H2O<1:2.0:8.0.
EFFECT: higher efficiency of soil restoration when producing environmentally safe product.
