Document Type and Number:

Japanese Patent JP2011000534

Kind Code:

A

Abstract:

To provide a fluorine-containing wastewater treatment method which can economically and efficiently perform stable high-level removal of fluorine from fluorine-containing wastewater with a simple means.

Disodium hydrogen phosphate and calcium chloride are made present in the fluorine-containing wastewater under pH adjustment to 4-8, and mixed in this condition to insolubilize the fluorine in the wastewater as fluoroapatite while generating calcium hydrogen phosphate dihydrate, and then solid-liquid separation is carried out to remove the fluorine in the wastewater.
