Eco-friendly and economically feasible methods of cleaning contaminated soil
Due to contamination of soil the role of farmlands becomes irrelevant. In this regard, it is necessary to develop new and use eco-friendly and economically feasible methods aimed at intensifying processes of soil decontamination. Now physical, chemical and biological methods of cleaning contaminated soil are widely used. Physical methods based on the use of electric current have become widespread. This is the technology of electrochemical and electrokinetic decontamination of contaminated soils. The authors proposed a biological product «Albit» which is able to significantly reduce oil pollution of soils. The rate of decomposition of oil in the soil under the influence of Albit increases on average 1,67-3,15 times. During industrial experiments it was demonstrated that the albit together with sowing oil-tolerant herbs for one growing season reduces oil contamination of the soil in 1,5-10,0 times. Biologics stimulate local soil biocenosis and create favorable conditions for transition of petroleum hydrocarbons in difficult-state. Formed organic compounds resembling humus having positive influence on soil fertility. A number of biological products, based on oil-degrading microorganisms active bacteria is considered. On the behalf of present and future generations comprehensive measures for the protection and rational use of scientifically sound land, its subsoil, water, flora and fauna, air and water purity preservation, ensure reproduction of natural wealth, and improve the human environment are needed.
