| titleOfInvention | Fluorine-containing wastewater treatment method and fluorine-containing wastewater treatment apparatus |
| abstract | A method for removing fluorine from fluorine-containing wastewater at a sufficiently low cost is provided. A water treatment method according to an embodiment includes a calcium agent, calcium fluoride, calcium sulfate, and calcium phosphate from a calcium agent storage tank and a functional powder storage tank, respectively, in a reaction tank having a reaction region and an overflow region. A step of crystallizing fluoride ions contained in the water to be treated on the surface of the mixed functional powder in the form of calcium fluoride, and a filter aid storage tank in the filter of the solid-liquid separator And supplying a filter aid to form a filter aid layer on the filter. Further, in the overflow region of the reaction tank, a step of precipitating and separating a part of the precipitated mixed functional powder containing calcium fluoride, and a remaining part of the mixed functional powder containing precipitated calcium fluoride in a solid-liquid separator. Supplying and removing by filtration through a filter and a filter aid layer to obtain treated water. [Selection] Figure 1 |
