The remediation of soil contaminated with oil products via up-to-date methods

Abstract

Due to the characteristics of the technological processes, the production activity of the enterprises in the oil industry affects the environment more seriously than other spheres. The contaminators of the enterprises of an oil producing complex combine the organic and mineral solutions as well. As the natural process of mineralization of polycyclic aromatic hydrocarbons is long enough, a necessity of the measures towards the acceleration of remediation processes occurs. The paper reviews the positive and negative aspects of the remediation methods applied for the soils contaminated with oil. The mechanical, agro-technical and chemical, as well as other methods of recultivation of the contaminated soils are implemented. The definition of the methods can change depending on the soil content, as well as on the contamination degree. It was specified that the environmental and economic efficiency may be achieved due to the enhancement of self-purification of soil with the employment of a complex of methods.
