METHOD FOR WASTEWATER INCLUDING FLUORINE TREATMENT USING ELECTROCHEMISTRY

摘要

PURPOSE: A method for processing fluorine-contained waste water using an electrochemical processing process is provided to control the fluorine content of processed water by separating a fluorine compound from the waste water. CONSTITUTION: In an electrochemical processing process(1), fluorine-contained waste water is introduced into an electrochemical reaction bath. Elution electrodes are regularly arranged in the electrochemical reaction bath. Power is supplied to the electrochemical reaction bath in order to generate a fluorine compound. In a chemical coagulation process(2), an aluminum-based compound, a sodium hydroxide, and a negative ion polymer coagulant are successively introduced into a chemical coagulation bath in order to flocate the fluorine compound. A solid-liquid separating process(3), the flocated fluorine compound is physically separated from the waste water.
