Extraction Refinement Oily of Soil and Microbe Decomposition of Hydrocorbons

With the purpose of improving the physical substances of oily soil, rehabilitation of its ability to reproduce the biomass and improving the soil ecology, the conduction of a two - stage recovery arrangements is tasted. During the first stage, the major part of the oil pollutant (97-99 %) is extracted from the soil by means of organic solvent and water as a process of extract ional refinement, and complete refinement of the soil by means of microbe decomposition is carried out on the second stage.
