The present invention provides a cadmium recovery facility and a recovery method for efficiently recovering cadmium from a plant that has absorbed cadmium. A cadmium-containing plant 11 is incinerated in an incinerator 12 at 500 ° C. or higher, preferably 765 ° C. or higher to vaporize cadmium as a simple substance and / or compound, and cool the vaporized cadmium simple substance and / or compound. The cadmium simple substance and / or the compound is cooled to below the boiling point of the cadmium simple substance and / or the compound, preferably 250 ° C. or less, more preferably 150 ° C. or less, and the precipitated cadmium simple substance and / or compound-containing powder 14 is obtained. A second filter comprising a bag filter provided with a filter cloth 17 which is collected by one collecting means 16 and provided downstream of the first collecting means 16 and which is covered with one or both of activated carbon and slaked lime. The collection means 18 collects one or more substances of nitrogen oxides, sulfur oxides, and dioxins that have passed through the first collection means 16. [Selection] Figure 1 |
