摘要
FIELD: process engineering.;SUBSTANCE: invention relates to environmental protection, particularly, to reclamation of soils contaminated with hydrocarbons (oil products), radioactive nuclides and heavy metals with the help of electric osmosis. Proposed method consists in inducing nonuniform electric field between central and peripheral electrodes and applying magnetic field perpendicular to cleaning zone. Proposed device comprises central electrode. Said electrode is composed of a rod with cross-section of polygonal shape with concave sides. System of peripheral electrodes is composed by separate rods. The latter are interconnected by plates arranged in zigzag line so that its recess or ledge is aligned with those of central electrode surface. Besides, proposed device comprises two extra solenoids arranged one above the other. First solenoid is plunged in submerged zone soil while second electrode is fixed by crossbar at the post extending through central electrode axis.;EFFECT: higher quality of cleaning.;4 cl, 4 dwg
