Description

Technical Field

[0001] The utility model relates to the technical field of fluorine-containing wastewater treatment, in particular to a device for treating fluorine-containing wastewater. Background Art

[0002] Fluoride-containing wastewater primarily originates from industrial production, particularly in industries using fluoride-containing minerals, such as aluminum electrolysis, steel, cement, bricks and tiles, ceramics, phosphate fertilizers, glass, semiconductors, and pharmaceuticals. During the production process, these industries generate fluoride-containing wastewater due to the decomposition of fluoride from the minerals. Treatment methods for fluoride-containing wastewater vary, including chemical precipitation, coagulation and sedimentation, adsorption, ion exchange, reverse osmosis, activated carbon defluoridation, electrodialysis, and electrocoagulation. Each method has its own unique characteristics and is suitable for treating fluoride-containing wastewater of varying concentrations and properties.

[0003] At present, when fluorine-containing wastewater is coagulated and precipitated, a large amount of precipitated impurities will be generated. When the wastewater is precipitated and needs to be discharged, some floating impurities in the water may follow the water flow into the drainage pipe. When a large amount of impurities enter the drainage pipe, it may cause the drainage pipe to be blocked, so staff need to clean it, which is more troublesome to operate. Utility Model Content
