Abstract:
A method for converting polychlorinated biphenyl oil into a resource by a chemical decomposition treatment, a pelletizing treatment and a thermal decomposition treatment,wherein the chemical decomposition treatment decomposes the polychlorinated biphenyl oil to powder including a metal salt by applying a decomposition action of CaO to said polychlorinated biphenyl oil and acting far-infrared rays emitted by quartz porphyry; the pelletizing treatment solidifies the powder, which is generated by said chemical decomposition treatment, into pellets; said thermal decomposition treatment thermally melts said pellets, which are generated by said pelletizing treatment, and glass cullet at a temperature above a thermal decomposition temperature of said polychlorinated biphenyl, and integrates said pellets and glass cullet as slag, wherein the integrated slag is cooled to be made into a solid to be reused as resources.
