METHOD OF OIL SLUDGE PURUFICATION FROM OIL AND OIL PRODUCTS Russian patent published in 2008 - IPC C02F3/34 C12S1/00 C12N1/26 

FIELD: chemistry.

SUBSTANCE: invention refers to biotechnology. Method lies in bringing into oil sludge at the beginning of first vegetation period of biotrin in amount 3-5 g per 1 kg of oil sludge, diammophos in amount 2-3 g per 1 kg of oil sludge, sawdust of broad-leaved trees in amount 100 g per 1 kg of oil sludge and suspension of oil-oxidising microorganisms. As oil-oxidising microorganisms, suspension of activated aboriginal oil-oxidising organisms or biopreparation "Rodotrin" with density 10⁵-10⁶ cell/ml at 50 ml per 1 kg of oil sludge is used. Then mixture is mixed, laid in layers with soil and sand, and after air supply, is ripped without mixing layers. At the beginning of the second vegetation period water solution of biotrin in amount 3 g per 1 kg of oil sludge and diammophos in amount of 3 g per 1 kg of oil sludge is brought in. At the beginning of the third vegetation period perennial grasses are sowed in amount 3 g of seeds per 1 m. Method of increasing effectiveness of oil sludge purification from oil and oil products.

EFFECT: increasing effectiveness of oil sludge purification from oil and oil products.
