FIELD: construction of roads; methods for purification of the petroleum-polluted soils from the oil products.
SUBSTANCE: the invention is pertaining to the method for purification of the petroleum-polluted soils from the oil products and may be used at construction of the roads with application of the oil-containing materials subjected to utilization. The method for purification of the petroleum-polluted soils from the oil products provides for the petroleum-polluted soil heating, the endless screwing, the gathering of the oil and the purified soil, putting the body of the endless screw conveyor in the oil heater, heating of the oil-polluted soil conduct during the endless screwing up to the temperature of 50-70°С by the contact-free method. The technical result of the invention is production of the high quality soil used for the road construction with the simultaneous utilization of the oil-containing industrial wastes with provision of the manufacturability and safety of the process of purification of the oil-polluted soil.
EFFECT: the invention ensures production of the high quality soil used for the road construction, the simultaneous utilization of the oil-containing industrial wastes, the manufacturability and safety of the process of purification of the oil-polluted soil.
