Method for converting polychlorinated biphenyl oil into a resource, agent for decomposing polyschlorinated bipheny oil, and reclaimed material

摘要

The method for converting harmful polychlorinated biphenyl (PCB) oil into a resource according to the invention comprises chemical decomposition treatment, pelletizing treatment and thermal decomposition treatment. The chemical decomposition treatment uses a decomposing agent including calcium oxide powder whose surface is coated with a vegetable oil and quartz porphyry powder, causes a decomposing action of CaO and far-infrared rays, which are emitted from quartz porphyry, to act onto polychlorinated biphenyl oil, and decomposes the polychlorinated biphenyl oil into powder including a metal salt. The pelletizing treatment hardens the powder produced by the chemical decomposition treatment into pellets. The thermal decomposition treatment melts the pellets produced by the pelletizing treatment and glass cullet at a temperature above the thermal decomposition temperature of the PCBs for molten integration of the pellets and glass cullet as slag. The slag obtained by the thermal decomposition treatment is cooled and the solid substance resulting therefrom is a radiator of far-infrared rays, and can be widely used as various types of construction materials and agricultural materials.
