| titleOfInvention | Waste liquid treatment method and waste liquid treatment device |
| abstract | (57) [Summary] (Modified) [Structure] After impregnating a carrier made of a porous resin with a solvent, the surface of the carrier is washed with water, and the carrier is dried to obtain an adsorbent 1 Activate 4 Then, the waste liquid is circulated through the activated adsorbent 14 to selectively adsorb and separate the TRU in the waste liquid for processing. Further, the adsorbent 14 on which TRU is adsorbed is washed with a nitric acid solution to elute TRU from the carrier, the nitric acid solution is drained, the carrier is again impregnated with the solvent, the surface of the carrier is washed with water, and the carrier is dried. Then, the adsorbent 14 is regenerated. The waste liquid is continuously treated by repeating the waste liquid treatment and the regeneration of the adsorbent 14. [Effect] Since it uses an adsorbent in which a solvent is impregnated into a porous resin that has a large contact area with waste liquid, it has high performance In addition, it is possible to selectively adsorb and treat the treated material. Further, since the adsorbent is used after being recycled, it is economically useful. |
