FIELD: oil pollution elimination.
SUBSTANCE: invention relates to biotechnological methods for environmental protection, in particular to restoration of soils polluted with crude oil, petroleum derivatives, and formation water. Method comprises treatment of area with dry activated sludge originated from pulp and paper plants, which is a mixture of microorganisms and nutrient substances with degree of concentration up to 20-35 g/dm3. Mixture is further supplemented by 0.3-1.5% of carbohydrate-mineral additive, straw to ensure additional aeration, lime to neutralize acidic soils or gypsum to neutralize highly alkaline soils. After that, bean plants are sown.
EFFECT: speeded up oil biodegradation process and increased soil cleaning degree.
