FIELD: chemistry.
SUBSTANCE: invention relates to the field of sewage water processing. The method of electrochemical removal of pollutants from sewage waters in accordance with the invention is realised in an installation of electric coagulation for the removal of the pollutants, including, at least, one anode and, at least, one cathode, and in the installation for electric oxidation for the oxidation of the pollutants, including, at least, one anode and, at least, one cathode, where oxidants are obtained in an electrochemical way. Depending on the type of sewage waters, a device between the installation of electric coagulation and the installation of electric oxidation can include an installation of electric floatation. The device also includes an installation for oxidant removal, which can include an electrode, releasing ions of metals, for carrying out a reaction with the residual oxidants and their removal. In some cases, in order to increase efficiency, a part of discharge from the installation of oxidant removal can be supplied for recirculation into the installation of electric coagulation.
EFFECT: invention can be used for the purification of water under conditions, when an access to systems of centralised sewage water treatment is absent and for the purification of water, containing badly decomposable pollutants, for instance, pharmaceutical wastes.
