[0002] Fluoride-containing wastewater refers to wastewater containing high concentrations of fluoride ions in industrial production, manufacturing or other processes. Fluoride ions can come from various sources, such as fluoride salts, fluoride compounds, fluorinated industrial wastewater, etc. Common fluoride-containing wastewater comes from the wastewater treatment processes of industries such as metal smelting, ore processing, chemical industry, and electronics manufacturing. The fluoride content in these wastewaters exceeds the environmental discharge standards or poses potential hazards to the ecological environment and human health. Currently, the methods commonly used for treating fluoride-containing wastewater are roughly divided into two categories: chemical precipitation method and adsorption method.
