CLEAN-UP OF OIL-CONTAMINATED LAND IN AZERBAIJAN

At present, as a result of anthropogenic activities, there is a large-scale pollution of the environment with harmful substances. Oil and oil products are one of the main environmental pollutants. Soil is under special stress, its morphological and physico-chemical properties tend to degrade, its self-purifying capacity is depressed, negative changes occur in the development and functional activity of organisms of the soil biocenosis. Limited land resources make it an urgent task to return all disturbed and degraded soils to economic use. From this point of view, the work devoted to the cleaning of soils from oil and oil products pollution is topical. The aim of the work was to compare two types of biotechnology used for cleaning of soils contaminated with oil and oil products using the method of activation of natural microflora with the introduction of microorganisms in the form of a biopreparation. Keywords: bioremediation, microflora activation, soil restoration, oil-oxidizing microorganisms, microbiological cleaning, soil self-purification.
