METHOD OF DECONTAMINATING SOILS POLLUTED BY OIL AND OIL SLIMES Russian patent published in 2011 - IPC B09C1/10 

FIELD: process engineering.

SUBSTANCE: invention relates to microbiological treatment of soils polluted by oil products, soil recultivation and may be used in oil extraction and processing industries. Proposed method comprises formation of separate working sites, soil sampling for oil content analysis. Results of analysis are fed into analyser for comparison with specified ratings. Thereafter, additional computer outputs personal recommendations on required amount of structure-forming agent, fertilisers and biological preparation for producing decontaminating layer on said working site. Fertilisers are applied in soil mass prepared on said site in the form of 0.07-0.1%-solution at the rate of 0.5-1 g/m². Processed layer is periodically sampled for content of oil products on different sites. Results of analysis are used by computer to output quantitative recommendations on additional application of ingredients into layer or instruction for cleaning said working site for next portion of soil to be decontaminated.

EFFECT: efficient and ecologically safe process at minimum costs.
