FIELD: chemistry.
SUBSTANCE: method for cleaning oil-containing wastewater is also proposed. The method includes cleaning oil-containing wastewater in a filter containing a housing with detachable filter cassettes, providing a filtration rate of 0.1-0.3 m/h. As the filtering load, granulated foamed polystyrene foams are used with a grain size of 2-3 mm with a bulk density of 17-22 kg/m3 at a thickness of the cassette of 0.3-0.5 m. A strain of hydrocarbon oxidizing bacteria Rhodococcus and / or Pseudomonas and/or Acinetobacter or a biologic oil decontaminator is introduced into the volume of the filtering charge in an effective amount.
EFFECT: method provides a deep cleaning of oil-containing wastewater.
