TREATING DEVICE FOR FLUORINE-CONTAINING WASTE WATER AND TREATMENT METHOD

摘要

PROBLEM TO BE SOLVED: To stably and efficiently treat fluorine-containing waste water by a continuous electric deionization device by solving the problem of the corrosion of an anode by HF when the continuous electric deionization device is applied to the treatment of the fluorine-containing waste water. SOLUTION: A fluorine adsorption resin device 2 is disposed in the fore stage of an RO membrane separator 1 or between the RO membrane separator 1 and the continuous electric deionization device 3 in the treating device and treatment method for the fluorine-containing waste water by successively passing the water to the RO membrane separator 1 and the continuous electric deionization device 3.
