Abstract
ABSTRACT As a result of Vosei-Golovnye pipeline break and consequental oil spill (Russia, Komi Republic) in 1994 about 80 hectares of the earth surface were contaminated, major part of which represents swampy soil. In the period of oil spill liquidation works, an original technology of swampy soil treatment and recovery was designed. The technology process of oil spill treatment and swampy soil rehabilitation includes 5 stages. 1st stage: oil spill containment by creating dikes of earth. 2nd stage: removal of gross oil concentrations on treated sections with the assistance of specially constructed drags. After the second stage residual oil concentration are not less than 250,000 mg/kg of peat cover. 3d stage: residual oil concentrations are hosed off by high pressure water. After the treatment is completed the oil concentration is reduced to 50,000–60,000 mg/kg of peat cover. 4th stage: cutting out 3 to 5 cm of peat cover polluted by oil and oil slime recovery on sections under cleaning. The oil concentration is reduced until the parameters which make possible normal vegetation of plants. 5th stage: biological recultivation during of which the recultivated sections are sowed with plants typical for this swampy region.
