COMPOSITION FOR REMOVING FLUORINE COMPONENT FROM WASTE WATER AND METHOD OF REMOVING FLUORINE COMPONENT FROM WASTE WATER

摘要

The present invention relates to an ingredients, it is used to remove a fluorine component from waste water comprising a kind of Al compounds, a ferric compound and an inorganic acid, wherein Al compounds, one mixing molar ratio of ferric compound and inorganic acid is Al conversions, Fe conversions, H+1: 0. respectively1 to 3.6: 1.1 to 4.0 for a fluorinated volume and a removing method is effectively used for removal fluorine component, and particularly fire resisting fluorine component, uses identical from waste water. By using ingredient of the invention, fluorine component (such as hydrofluoric acid) and be contained in waste water can hydrolyzable fluoboric acid can efficiently and economically and rapidly be decomposed and by continuity method remove.
