PROBLEM TO BE SOLVED: To introduce a magnetic purifying material into an object to be treated containing harmful substances such as radioactive soil, pollutants and coarse foreign matters, and continuously stir, remove, magnetic separation, dehydration, drying, re-collection of magnetic separation, etc. Provided is a purification and recovery device for purifying an object to be processed and separating and recovering a magnetic decontamination substance. An object to be treated containing pollutants and the like is mixed and stirred with a magnetic purification material, and the removal of coarse foreign substances and the separation and recovery of the magnetic purification material are continuously performed, followed by dehydration and drying, and further magnetic selection. The recovery device further collects the magnetic purification material, and as a result, the object to be treated is purified. [Selection] Figure 1 |
