Composition for removing fluorine component from waste water and method of removing fluorine component from waste water

摘要

The present invention relates to a composition for removing a fluorine component from wastewater, which comprises an Al compound, a ferric compound and an inorganic acid, wherein a mixing molar ratio of the Al compound, the ferric compound, and the inorganic acid is respectively Al conversion, Fe conversion, H⁺1: 0.1 to 3.6: 1.1 to 4.0 in terms of a fluorine content, and a removing method effective for removing fluorine components, particularly refractory fluorine components, from waste water using the same. By using the composition of the present invention, fluorine components such as hydrofluoric acid and hydrolyzable borofluoric acid contained in wastewater can be efficiently and economically and quickly decomposed and removed by a continuous process.
