BIOREMEDIATION OF HYDROCARBON-CONTAMINATED SOIL BY BIOLOGICALLY ACTIVATED SOIL

摘要

The present invention relates to a method for biological restoration of oil-contaminated soil using soil in which indigenous microorganisms having oil-degrading capacity are adapted to oil contaminants in soil, and that is, in which microorganisms are accumulated. Promote the activity of effective microorganisms with oil-degrading ability in oil-contaminated soil through proper supply of nutrients, moisture, and oxygen, which are essential elements for oil pollution, and actively disintegrate oil pollutants in soils with increased number of effective microorganisms. The present invention relates to a method for biologically restoring a part or all of the microbial aggregate soil in a state after mixing with contaminated soil.;Since the biological restoration method by the microbial integrated soil according to the present invention utilizes effective microorganisms adapted to the site contaminated soil conditions, it has a cost-saving effect due to the non-microbial agent use and the introduction of external microorganisms compared to the biological restoration method in which commercial microbial agent is introduced. It is possible to prevent soil ecosystem disturbance caused by ecologically stable soil pollution restoration.
