Abstract: The accelerated industrial process has led to an increase in the amount of fluorinecontaining wastewater，which The accelerated industrial process has led to an increase in the amount of fluorinecontaining wastewater，which has caused great harm to life and environment.The efficient and environmentally friendly treatment of fluorine containing wastewater has become a hot research topic in the world.Various treatment methods for fluorine containing wastewater，such as precipitation method，electrochemical method，adsorption method，ion exchange resin method and microbial fluorine remo val method，were described.The latest wastewater defluoridation technologies in China，such as fluidized bed crystallization method，precipitation method using a mixture of calcium carbonate and calcium hydroxide as precipitant，rectification method of a rectification system composed of rectification tank filler rectification column condenser storage device，chelating resin adsorption method of surface coated with aminophosphonic acid compound containing chlorine and aluminum ion structure，ion exchange method of hybrid material formed by anion exchange resin and lithium aluminum metal，electrocoagulation ad sorption method，enhanced magnesium precipitation method，were summarized respectively.In the actual treatment of fluo rine containing wastewater，appropriate methods should be adopted for wastewater of different natures.
