METHOD OF REMOVING HYDROCARBON CONTAMINANTS FROM SOILS

摘要

FIELD: process engineering.SUBSTANCE: invention relates to biotechnologies, ecology and reclamation. Proposed method comprises introduction of hydrocarbon oxidant microorganisms and peroxide compound. Soil is cleaned at two steps. At first step, peroxide compound is introduced into soil in amount of 3-10% of the weight of hydrocarbon contamination. At second step, hydrocarbon oxidant microorganisms plus mineral nutrient medium are introduced at a time therein. Note here that said second step is performed in at least three days after said first step. Said hydrocarbon oxidant microorganisms represent consortium of cultures Candida maltose All-Russian collection of industrial microorganisms Y-3446 and Dietzia maris All-Russian collection of industrial microorganisms Ac-1824 while peroxide compound represents a hydrogen peroxide or calcium peroxide.EFFECT: higher efficiency of soil reclamation.4 tbl, 4 ex
