Description

Technical Field

[0001] The invention relates to the field of fluidized bed fluorine-containing wastewater treatment, in particular to a fluidized bed fluorine-containing wastewater treatment system. Background Art

[0002] With the increasing number of industrial production activities, the emission of various pollutants has also increased. In particular, fluoride-containing wastewater has become the focus of environmental protection due to its unique chemical properties and potential hazards. At present, the treatment methods for fluoride-containing wastewater mainly include chemical precipitation, adsorption, ion exchange, electrodialysis and other methods. These treatment technologies have their own advantages and meet the needs of different industries to a certain extent, while also promoting the development of environmental protection work.

[0003] The chemical precipitation method adds calcium salts or aluminum salts and other reagents to make fluoride ions form insoluble compounds for precipitation and removal; the adsorption method uses a large number of active sites on the surface of porous materials such as activated carbon and zeolite to adsorb fluoride ions; ion exchange relies on cationic resins to capture fluoride in water and replace it; electrodialysis uses the action of a DC electric field to drive charged fluoride ions to migrate to a specific area, thereby achieving the purpose of separation and purification. However, although the above methods can effectively reduce the fluoride content in wastewater, they still have problems of high cost and low efficiency. Taking chemical precipitation as an example, although it can significantly reduce the fluoride content, the reaction speed is slow and it takes a long time to achieve the ideal precipitation effect, and subsequent sludge treatment is also a problem. For example, the adsorption method is easy to operate, but it is prone to saturation failure during actual application, and the adsorption material needs to be replaced regularly, which increases the operation and maintenance costs. At the same time, solid impurities may exist in fluoride-containing wastewater. If the solid impurities are not removed, it will affect the treatment of fluoride wastewater. Summary of the invention
