FIELD: technological processes, water treatment.
SUBSTANCE: invention is related to treatment of natural and sewage waters from dissolved and mechanical admixtures. Method of natural and sewage waters consists in filtration of contaminated liquid through heterogeneous disperse filtering material, which consists of two or several components and is installed in sign-constant electric field above supporting layer. Filtering bed is filled with metal electroconductive inclusions with capability of electrochemical dissolution in the form of filings with hydraulic fineness equal to hydraulic fineness of filtering bed particles. Device for method implementation includes cylindrical casing, which contains semi-annular insoluble electrodes connected to DC source, filtering bed installed in interelectrode space above supporting layer, and also pipelines of initial, service, flushing and treated water. Device is additionally equipped with ejector and reservoir for metal inclusions introduced into filtering bed. Invention makes it possible to intensify process of natural and sewage water treatment from contaminants.
EFFECT: intensification of process of natural and sewage waters treatment from contaminants.
