Recultivation of oil contaminated soil using organic wastes in the Kola North conditions

Extraction, transportation, transshipment and storage of oil lead to accidental pollution of soil with oil products. To solve this problem, the possibility of using organic waste produced by the Murmansk region for the remediation of oil-polluted soils in the Kola North has been studied. The study has been carried out for three months at temperatures from 10 to 18 °C simulating the temperature conditions of the summer months on the Kola Peninsula. The contaminated soil was collected outside of Murmansk borders and the zones of industrial pollution on the Kola Peninsula. The soil type is podzol. Pollution modeling has been carried out by introducing F-5 fuel oil into the soil. The following organic components have been used as reclamation agents: excess activated sludge from biological treatment facilities of the enterprise Murmanskvodokanal; Saccharomyces cerevisiae brewery sedimentary beer yeast of the Murmansk region; chitosan - a product of conversion of Kamchatka crab processing waste...
