The present invention provides a treatment facility for polychlorinated biphenyl contaminants containing heavy metals contaminated with polychlorinated biphenyl, which has a low running cost and final disposal cost. A plasma decomposition apparatus that decomposes PCB with plasma while treating PCB contaminants at a high temperature and volatilizes contained heavy metals, and a dust removal apparatus that removes dust contained in the exhaust of the plasma decomposition apparatus. In the polychlorinated biphenyl contaminant treatment facility 10 provided with the dust, the dust removing device 18 collects dust in the exhaust gas, removes the hydrogen chloride and heavy metal contained therein by reacting with an alkaline agent, and discharges the primary treatment exhaust gas. The first bag filter 15 and the dust remaining in the primary treatment exhaust gas are collected and the remaining hydrogen chloride and heavy metal are removed by reacting with an alkaline agent to decompose PCBs, dioxins, and undecomposed PCBs. And a second bag filter 17 for removing the secondary treatment exhaust gas by adsorbing the activated carbon to the activated carbon. [Selection] Figure 1 |
