Abstract

The paper presents the results of treatment of transformer oil containing less than 2 ppm polychlorinated biphenyls (PCB) in a plant of high-temperature plasma melting of ash residues after the municipal waste incineration. The content of undecomposed PCBs, dioxins, and other hazardous waste in all secondary products of treatment (off gases; slag; secondary fly ash; process water used for slag granulation) was analyzed by different methods. Performed analytical investigations showed high ecological degree of PCB decomposition in the plant of plasma-thermal treatment of ashes after incinerators.
