COMPOSITION FOR SOIL PURIFICATION FROM OIL POLLUTIONS Russian patent published in 2004 - IPC

FIELD: compositions used for soil purification from oil pollution.

SUBSTANCE: the invention presents a composition used for soil purification from oil pollutions. The composition contains oil-oxidizing microorganisms, an adsorbent and a fertilizer. In the capacity of the adsorbent and the source of microorganisms It contains peat, and in the capacity of fertilizers- nitrogenous phosphorus mineral fertilizers provided, that 100 g of that absolutely dry substance contains 12-15 % of nitrogen and 1.8-2.3 % of phosphorus and the ratio of nitrogen and phosphorus is 1:0.15 at the following relationship of components (in mass %): nitrogenous fertilizer - 24.25-44.10, phosphorus fertilizer - 6.50-8.80, peat (absolutely dry substance)- 47.10-69.25. For purification of the soil with relatively low degree of oil and oil products pollution they offer the composition containing in 100 g of the absolutely dry substance 0.15-0.30 % of nitrogen and 0.065-0.13 % of phosphorus at the following ratio of components (in mass %): Nitrogenous fertilizer - 0.260-0.870, phosphorous fertilizer-0.235-0.500, peat (absolutely dry substance) - the rest. Technical result is production of reception of more simple in component structure and in the method of preparation ecologically pure and cheap composition for a recultivation of the oil-polluted soils, that allows for a short time to purify the different kinds of soils of a different level of pollution.

EFFECT: the invention allows for a short time to purify the different kinds of soils of a different level of pollution.
