Chemical precipitation adsorption device for treating high fluoride wastewater

The utility model relates to a chemical precipitation adsorption device for treating high fluoride wastewater. The device comprises a fluorine removal reaction tank; the flocculation tank is communicated with the fluorine removal reaction tank; a filtering layer is arranged in the settling pond, a water inlet is formed in the position, located below the filtering layer, in the settling pond, and a water outlet is formed in the position, located above the filtering layer, in the settling pond; the water inlet of the sedimentation tank is connected with the flocculation tank through a pipeline, and wastewater flowing from the flocculation tank flows upwards through the filter layer and flows out through the water outlet. According to the chemical precipitation adsorption device for treating the high fluoride wastewater, provided by the invention, through multi-stage fluorine removal, the fluoride in the discharged water can be ensured to reach 1.0 mg/L or below, the equipment structure can be effectively simpli
