Abstract: Starosilets M.M., Dyachok V.V. (supervisor). Study of the dynamics of the biological decomposition of mineral oils with the participation of the biological preparation "Econadine" Master’s qualification thesis. - Lviv Polytechnic National University, Lviv, 2022. Extended abstract The master’s qualification work is devoted to the solution of the scientific and practical task - increasing the level of ecological safety of the hydrosphere as a result of the introduction of the technology of decomposition of complex organic compounds that are part of mineral transformer oils with the help of microorganisms biodestructors of oil hydrocarbons "Econadin". The process of biochemical decomposition of water contaminated with transformer oil was investigated. Study object - technologies for the decomposition of complex organic compounds that are part of mineral transformer oils with the help of microorganisms that biodestroy oil hydrocarbons. Scope ofresearch - processes of using microorganisms of oil hydrocarbon biodestroyers for the decomposition of transformer oil. Goal of research: to increase the level of ecological safety of the hydrosphere as a result of the introduction of the technology for the decomposition of complex organic compounds that are part of mineral transformer oils with the help of microorganisms that biodestroy oil hydrocarbons. The paper presents a study of the kinetics of biochemical decomposition of complex organic compounds that are part of mineral transformer oils and enter waste water. The process of biochemical decomposition of transformer oil-contaminated water with the help of microorganisms biodestructors of oil hydrocarbons, namely the biological preparation "Econadine", was studied. The kinetic constants of biochemical decomposition of transformer oil in waste water were determined. The obtained values ??indicate that the researched cleaning method has the prospect of being used in practice to reduce the concentration of pollutants in water containing petroleum products. Using a mathematical model and research results, a technological scheme of biochemical treatment of waste water contaminated with transformer oil was developed. The dimensions of the main device - a two-chamber aerotank-settling tank - have been calculated. The section "Economics and enterprise management" has been developed. Key words: ecological safety, microorganisms, cleaning, biodestructures, constants of biological decomposition References 1. Maria J. Lapponi, Mariana B. Mendez, Jorge A. Trelles, Cintia W. Rivero.
