PROBLEM TO BE SOLVED: To provide a method and an apparatus for treating fluorine-containing water which can continue the treatment of fluorine-containing water without interruption during the regeneration of a granular material mainly comprising calcium carbonate. SOLUTION: The fluorine-containing water treatment apparatus comprises a transfer pipe 8 having a first opening 8a opened at a part located at the lower part of a packed bed 4 and a second opening 8b opened at a part located higher than the upper surface of the packed bed 4, a fluid supply means 10 for supplying fluid into the transfer pipe 8 so that upward flow of a fluid is generated in the transfer pipe 8 to transfer the granular material and treated water sucked from a first opening 8a into the transfer pipe 8, films of calcium fluoride of the granular material are broken and removed by mutual collision in the granular material and collision with the inner wall of the transfer pipe 8, and the granular material and the treated water are discharged from a second opening 8b, and a separation mean for separating the granular material and the treat water to return the granular material discharged from the second opening 8b to the packed bed 4, and to discharge the treated water discharged from the second opening 8b to the outside of a reaction tank 2.
