FIELD: technical microbiology. SUBSTANCE: waste were heated to 50-60 C, subjected for effect with emulsifier, purified preliminary by oil settling, water is separated and used as nutrient medium for microorganism culturing. Precipitate after settling is combined with water saturated with "hungry" microorganisms and fed to detoxication under aerobic conditions using the grown microorganisms. Treated and detoxicated precipitate is removed and water with microorganisms excess is recovered at stage of microorganism culturing. Method is used in machine engineering for the spent oil treatment. EFFECT: improved method of treatment, enhanced effectiveness. 1 dwg
