Project summaryPurification of territories from oil polluted soils and surface water in the areas of oil extraction and transportation is an essential environmental problem, the importance of which has no doubts. For example, only in the Komi Republic there exist 358 lakes fully polluted by oil and the area of oil leakages is over 450 sq.km. Great attention is paid lately to the methods of microbiological oil utilization with the use of adsorbents with high adsorbing capacity.
The project provides for developing the technology of microbiological utilization of the used-up adsorbents of oil products, made on the basis of peat and hydrolysis lignine with the use of preparations-biodestructors. The research is needed because no efficient and environmentally safe method of utilizing the used-up adsorbents is in place now. Environmentally safe are adsorbents produced from natural materials, including peat and hydrolysis lignine that is the waste product of timber processing. Adsorbents made of these materials have high adsorbing capacity for oil. We suppose to study efficiency of hydrocarbon-oxidating activity of microorganisms on adsorbents after adsorption of oil and oil products. Depending on surfaces cleared (soils and water reservoirs), two means of using microbiological preparations will be applied: preliminary enrichment of adsorbents brought to the soil surface and placing of preparations on adsorbents used on water surfaces.
