FIELD: technological processes; environment protection.
SUBSTANCE: invention is related to environment protection, in particular to methods for cleaning of bed slit in water reservoirs and channels contaminated with oil and oil products, and also bed slit of mud pits and sewage water reservoirs of oil-processing plants. Method includes collection of oil liquid fraction, placement of oligochaetes of Tubificidae family on water reservoir bottom in amount from 20 to 65 g/m2, creation of concentration level of oxygen dissolved in near-bottom layers of water by means of water reservoir aeration with application of aerating devices, and at the same time nitric and phosphorous mineral fertilisers are introduced.
EFFECT: increased extent of cleaning at simultaneous simplification of method.
