FIELD: treatment facilities.
SUBSTANCE: invention relates to environment protection and can be used to treat industrial effluents polluted with oil products, phenols, iron salts and suspended particles. The method involves filtration through alternating layers of fine-filament basaltic and/or polypropylene fibres and a dispersed adsorbent which is a mixture of spherical ashes produced from thermal power plant wastes and iron oxide hydroxide in the form of mineral sediment obtained at the underground water iron removal plants, preferably thermally treated under the temperature of 150-350°C during 3-5 hours.
EFFECT: invention provides for the improvement of purification efficiency and expansion of the filtering materials range.
