FIELD: process engineering.
SUBSTANCE: invention relates to purification of soils contaminated by oil products. Proposed method consists in adding natural sorbent into soil to preset concentration of contaminant in soil. Prior to adding the sorbent, contaminant concentration is measured in mixing contaminated soil with sorbent. Then the weight of sorbent to be mixed with soil contaminated by pre-determined contaminant to reach preset concentration of said contaminant. Contaminated soil is damped, calculated sorbent bulk is distributed over contaminated soil surface and sorbent is mixed with said contaminated soil. Glauconite is used a said sorbent. Biopreparation is added to sorbent. Said biopreparation represents cultures of hydrocarbon-oxidising microorganisms and associations of soil oil-oxidising bacteria at soil temperature exceeding +15°C while at +15°C and below, micellar fungi are used.
EFFECT: detoxication of soils.
