PURPOSE: A wastewater treatment process using an electrodialysis apparatus is provided to enhance the efficiency of the electrodialysis apparatus by applying a proper chemical washing period on the process, and to prevent environmental contamination. CONSTITUTION: An electrodialysis apparatus includes an oxidation electrode, a reduction electrode, a plurality of cation exchange films, a plurality of anion exchange films, a plurality of spacers, and a control member. A wire for electrical resistivity measurement is inserted into the spacer. A wastewater treatment process includes a step for measuring electric resistance of the electrodialysis apparatus, a step for performing chemical washing after stopping the electrodialysis, and a step for repeating above steps. |
