Harmless treatment method of industrial waste containing PCB

摘要

It is an object of the present invention to provide a harmless treatment method for preventing the discharge of DXN into the atmosphere of industrial wastes containing PCBs that are harmful to human bodies and are difficult to decompose in nature.;To this end, the present invention (a) a process for separating the PCB-containing material from the industrial waste containing the chlorine PCB and (b) the industrial waste separated the material containing the chlorine alone, or the separated PCB It is composed of a process of dissolving and refining the industrial waste at 1,100 ° C or above, and thermally decomposing and decomposing the PCB-containing material by adding it to a melting / refining furnace using extremely electric energy in parallel with the substances contained therein. .
