FIELD: oil-polluted water treatment. SUBSTANCE: invention relates to oil-containing water treatment, which is accomplished by two-step centrifugal treatment, first in horizontal and then in vertical hydrocyclones, followed by settling and filtration on granule-filled cartridge exposed to electric field. Vertical hydrocyclone is provided with wheel having spiral stream-stabilizing guides. Several vertical hydrocyclones fastened in separation disc may be used. EFFECT: achieved water purity allowing directly pouring it into natural reservoirs avoiding use of posttreatment means. 13 cl, 23 dwg
