FIELD: chemistry.
SUBSTANCE: invention relates to biotechnology. Method involves addition to the contaminated soil of packed and dehydrated excess active sludge from biological purification plants of oily water effluents obtained after treatment of industrial and domestic waste water with active sludge in a mixture with biological preparation Destroil, added to waste water after every 25-30 days in amount of 1.5-2.0 g per 1 m3 of the water-sludge mixture in an aerotank. Sludge is taken in amount of 3-5 kg (in terms of dry substance) per 1 m2 of soil.
EFFECT: higher degree of purification of soil and ground from oil products.
