FIELD: environmental protection; oil and gas producing industry; methods of purification of subterranean water beds and soils from industrial pollution. ^ SUBSTANCE: the invention is pertaining to the field of environmental protection, in particular, to purification of the subterranean water beds and soils from industrial pollution by liquid hydrocarbons. In the polluted zone they drill a borehole, create and maintain in it a negative pressure within the limits of 2 kgf/cm2 up to 0.8 kgf/cm2. At that they simultaneously exercise extraction of the product of impurity from the borehole. The technical result of the invention is an increased amount of the pollution product extracted from the borehole per a unit of time. ^ EFFECT: the invention ensures an increased amount of the pollution product extracted from the borehole and its purification per a unit of time. ^ 5 cl, 1 dwg |
