FIELD: spilt oil removal. SUBSTANCE: pit preliminarily activated by nitrogen- and phosphorus-containing mineral additives is added to oil-polluted soil, which is then incubated in mesophile conditions for 3 to 7 days to increase population of hydrocarbon-oxidizing microorganisms, trace minerals indispensable for vital activity of microflora being contained in activated pit. The latter enables sorption of oil hydrocarbons and simultaneously contains oil- assimilation microorganism cultures ensuring very rapid oil destruction. EFFECT: enhanced soil purification efficiency. 2 ex
