Resource utilization system and process for fluorine-containing wastewater in mine

The invention discloses a resource utilization system and process for fluorine-containing wastewater in a mine. The resource utilization system comprises the following specific working procedures: S1,mine water firstly enters an adjusting water tank to be homogenized and mixed, effluent enters a primary chemical precipitation device, a flocculating agent and a coagulant are added to remove suspended matters in the water; S2, precipitated effluent sequentially enters a sand filtration unit and an ultrafiltration unit to remove SS and colloids in the effluent; and S3, resin effluent enters a decarburization unit for removal of alkalinity in the effluent. The invention relates to the technical field of resource utilization and recovery. According to the resource utilization system and process for the fluorine-containing wastewater in the mine, resin regeneration waste liquid is utilized to treat the fluorine-containing wastewater; the resin regeneration waste liquid enters a nanofiltration system, and system pro
