The setting of the discharge port 9 can facilitate the removal of the activated alumina filler 5 that has been used for a long time in the main cylinder body 1, so that the activated alumina filler 5 can be regenerated by the regeneration system. After regeneration, the performance of the activated alumina filler 5 can be restored to its original state, and it can be used repeatedly for a long time. The activated alumina filler 5 can effectively adsorb and exchange fluoride ions in water, and the principle is the existing technology.
