METHOD OF SOIL TREATMENT FROM THE OIL POLLUTION Russian patent published in 1994 - IPC

Abstract RU 2019527 C1

FIELD: microbiological treatment of soil. SUBSTANCE: soil surface is treated with aqueous suspension of bacterial culture Rhodococcus erythropolis E-15 in the mixture with mineral fertilizer - nitro-ammophoska or nitro-ammophoska and sodium nitrate. Aqueous suspension is prepared in solution of one-third of nitro-ammophoska required quantity, and the rest fertilizer quantity is added as a dry substance. Consumption of bacterial culture is 1-10 g/m² soil, that of nitro-ammophoska is 115 g/m² soil, and sodium nitrate is 400 g/m² soil. Invention provides acceleration of oil hydrocarbons degradation at the low temperatures. EFFECT: improved method of soil treatment. 3 cl, 2 fig, 2 tbl
