Biological reclamation of soils contaminated with fuel oil, using vermiculture earthworms Dendrobena veneta and microbiological preparations Baikal-EM, Tamir, Vostok

The technology of soil remediation contaminated with fuel oil at a concentration of 150 g/kg of soil for one year in Western Siberia using microbiological preparations and earthworms was developed. Earthworms have great potential for removing hydrocarbons from the soil, even at high concentrations up to 100 g/kg. Method of remediation of oil-contaminated soils with fuel oil content up to 150 g/kg by microorganisms (lactic acid, nitrogen-fixing, photosynthetic bacteria) and earthworms Dendrobaena veneta. A method for cleaning and restoring the environmental functions of substrates contaminated with fuel oil and other petroleum products, was that the substrate was treated with biologics, carried out dump soil treatment and steamed for one month, then introduced earthworms in an amount of 1000 PCs./m2, as a nutrient medium used cattle manure (cattle) in a dose of 1 t/ha of contaminated landfill.
