Stage: PROBLEM TO BE SOLVED: To provide a crystallization reaction method and a crystallization reaction apparatus capable of improving a recovery rate, in a method for recovering a crystallization object material from water to be treated containing a crystallization object material such as fluorine.SOLUTION: A crystallization reaction method includes a crystallization reaction step for adding a calcium agent into water to be treated containing a crystallization object material in a crystallization reaction tank 10, to thereby generate a crystal of a slightly soluble calcium salt. In the crystallization reaction step, a concentration of SiO2 in the crystallization reaction tank 10 is 100 mg/L or less.SELECTED DRAWING: Figure 1 (Grant)
