FIELD: chemical industry, purification of local sewage from toxic contamination. SUBSTANCE: in compliance with invention local sewage is treated in electrolyser with use of soluble aluminum laminated electrodes with addition of up to 1.0 per cent by mass of ammonium chloride and up to 1.0 per cent by mass of sodium hydroxide. Process is conducted with density of alternating sinusoidal current 0.1-1.0 A/sq cm in temperature interval 40-95 C. Liquid effluent purified from toxic contamination is suitable for industrial utilization after separation of sediments. EFFECT: simplified implementation of process, improved degree of purification of sewage. 1 tbl
