To provide a separation treatment method for separating and removing PCB from powder-like PCB contaminant such as sludge or soil at improved treatment efficiency.
The PCB contaminant separation treatment method comprises: a separation process of adding a separation assistant d to the PCB contaminant p, supplying it to a vacuum heating separation furnace 1, bringing the PCB contaminant into a pressure-reduced state by a vacuum pump 9 communicated with the vacuum heating separation furnace 1 and also heating and evaporating the PCB contained in the PCB contaminant p; and an absorption process of introducing the PCB to an oil shower column 2 arranged between the vacuum heating separation furnace 1 and the vacuum pump 9, bringing it into contact with oil and condensing and absorbing it.
