FIELD: oil and gas industry.
SUBSTANCE: method for removing oil and oil products from soil consists in soil treatment with liquid form of biopreparation including aerobic oil-oxidising bacteria. Prior to soil treatment with the above biopreparation, nitrogen-phosphorus-potassium mineral fertiliser and in addition fish flour is added immediately to soil. The best result is achieved when Naftox preparation with bacterial culture Mycobacterium sp. 5 KB is used. It is recommended to add azophoska as mineral fertiliser to contaminated soil in quantity of 50-100 g/m2, and fish flour in quantity of 150-300 g/m2.
EFFECT: method allows increasing cleaning efficiency of soil contaminated with oil products at using liquid form of biopreparation by means of growth stimulation of the number of bacteria added to soil.
