TREATING METHOD OF MATERIAL TO WHICH PCB ADHERES

摘要

PROBLEM TO BE SOLVED: To efficiently and safely treat the instruments contaminated by PCB. SOLUTION: Crushing treatment, melting treatment and solidifying treatment are performed in order. In the crushing treatment, the instruments to which PCB adheres is crushed into small pieces. In the melting treatment, the small pieces of the crushed instruments are molten by heating to decompose the PCB to harmless components. In the solidifying treatment, the molten matter of the small pieces of the instruments is cooled to solidify the molten matter to solid. The reuse and disposal of the solid are easily performed by solidifying the molten matter of the instruments after fractionating the molten matter to metal solid 11 and inorganic solid 12.
