FIELD: methods of extermination of organic toxicants. SUBSTANCE: organic toxicants are subjected to incineration in the presence of spent condensed black liquor obtained in the stage of evaporation in the process of recovery at production of cellulose by the method of alkaline boiling. The process is conducted at a temperature of 1100 to 1400 C for 3 to 30 s in a black-liquor recovery boiling unit. The offered method provides for processing both of liquid and powdery toxicants and results practically in complex extermination of toxicants. EFFECT: considerably reduced material costs. 3 cl, 4 dwg
