specific Embodiment approach 1
[0013] Specific embodiment one: the resuscitating method of the anion exchange resin polluted by organic matter and the medicament formula in this embodiment are carried out according to the following steps: one, the transformation of anion exchange resin: be that the salt water of 8%~10% with weight percentage concentration is to anion exchange The resin is soaked in a cycle, the temperature is 18~22°C, the circulation flow rate is 2.5~3.5m / h, and the circulation is adopted in the way of top in and bottom out. After 6~10 hours of cyclic soaking, the transformation is completed. 2. Flushing: After the transformation is completed, the waste liquid is drained, and the anion exchange resin is reversely flushed with desalted water. The flushing time is 1.5~2.5h, and the flushing flow rate is 18~22m / h. 3. Resuscitating the anion exchange resin by removing organic contamination: the total volume of the resuscitating agent is 4 times the volume of the anion exchange resin to be recove...
specific Embodiment approach 2
[0018] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that in step 1, the anion exchange resin is transformed into an anion exchange resin with a weight percent concentration of 8.5%~9.5% saline for cyclic soaking of the anion exchange resin, and the temperature is 19~21 ℃, the circulation flow rate is 2.8~3.2m / h, the circulation is adopted in the way of top in and bottom out, and the cycle soaking time is 7~9 hours. Other steps and parameters are the same as in the first embodiment.
specific Embodiment approach 3
[0019] Specific embodiment three: the difference between this embodiment and specific embodiment one is that in step one, the anion exchange resin is transformed into an anion exchange resin with a weight percent concentration of 9% saline to circulate and soak the anion exchange resin at a temperature of 20°C and a circulation flow rate of 3m / h, using top-in and bottom-out circulation, and the cycle soaking time is 8 hours. Other steps and parameters are the same as in the first embodiment.
