A study of the dynamics of change in the concentration of pollutants discharges from electrometallurgical enterprises was carried out. Analytical data are presented for the following ingredients: suspended substances, dry residue, chlorides, sulfates, nitrates, nitrites, ammonium nitrogen, fluorides, iron in general. Possible ways of reducing harmful discharges into the water intake facility (Oskol River) have been analyzed, and the most effective method of combating them for the conditions of the Oskolsk electrometallurgical industrial complex (OEMIC) has been chosen. The use of electrolytic hydrogen for the electroflotation of pollutants from aqueous solutions in the technological processes of water treatment for reuse in the water supply systems of electrometallurgical enterprises is proposed.
