Claims (1)

Способ очистки капиллярно - пористой среды, загрязненной нефтью и нефтепродуктами, путем введения в зону очистки раствора нефтеокисляющих микроорганизмов, отличающийся тем, что в зоне очистки размещают электроды - анод и катод, затем в зону очистки вводят электропроводящую жидкость, например, воду, пропускают между электродами постоянный электрический ток для создания электроосмотического движения жидкости в зоне очистки, удаляют жидкость с загрязнениями, собирающуюся у катода, при этом контролируют концентрацию в зоне очистки веществ, угнетающих жизнедеятельность нефтеокисляющих микроорганизмов и, при снижении их концентрации до значений, безопасных для жизнедеятельности нефтеокисляющих микроорганизмов, вводят содержащий их раствор в зону очистки.A method of cleaning a capillary-porous medium contaminated with oil and oil products by introducing a solution of oil-oxidizing microorganisms into the cleaning zone, characterized in that electrodes — anode and cathode — are placed in the cleaning zone, then an electrically conductive liquid is introduced into the cleaning zone, for example, water, and passed between the electrodes direct electric current to create electroosmotic fluid movement in the cleaning zone, remove the contaminated liquid collected at the cathode, while controlling the concentration in the cleaning zone of substances that inhibit the vital activity of oil-oxidizing microorganisms and, when their concentration is reduced to values that are safe for the life of oil-oxidizing microorganisms, a solution containing them is introduced into the treatment zone.
