Zusammenfassung:FIELD: detoxification methods. ^ SUBSTANCE: invention relates to detoxifying polychlorinated organic wastes containing toxic high-boiling substances. For this aim, wastes are hydrogenised on supported palladium catalyst at 60-130°C and pressure 10-50 atm in presence of 10-20% sodium hydroxide solution in biphasic water/hydrocarbon system. According to invention, hydrocarbon solution of waste, prior to be subjected to hydrogenation, is filtered at 70-100°C through filter of nonwoven polymeric material allowing waste particles at least 1 mum in size to be retained, after which reaction mixture is charged with lower aliphatic alcohol in amount 1 to 20 wt %. ^ EFFECT: essentially increased waste processing productivity with minimum formation of secondary toxic substances. ^ 5 cl, 1 tbl, 12 ex
