摘要： The invention discloses a modularized fluoride-containing wastewater treating apparatus, comprising: a fluoride removal module, which is used to remove most of the fluoride in the high-concentration fluoride-containing wastewater transported to the fluoride removal module by cryolite crystallizing to generate a mixture of unextracted cryolite crystals and a low-concentration fluoride-containing wastewater; and an extracting module connected with the fluoride removal module, which is used to extract the mixture of unextracted cryolite crystals and a low-concentration fluoride-containing wastewater to separate cryolite crystals with a water content less than 60% or cryolite crystals with a water content less than 10% and a purity of 95%, a wastewater that meets the discharge standard and a condensed fluoride-containing liquid, wherein the condensed fluoride-containing liquid will be recycled to the fluoride removal module.
