In addition, such a treatment device using an electrolytic stripping method is used in, for example, an anaerobic tank, an aerobic tank, and a processing tank, and the sewage of the processing water tank can be passed through the iron ion used to react with the dish acid. The eluted electrolytic device is circulated in a sewage treatment device constituted by an anaerobic tank. [Problems to be Solved by the Invention] The phosphorus removal device according to the above electrolytic method uses a method in which a direct current is passed between the electrodes to extract iron ions. However, since the phosphorus removal performance depends on the application of Chinese national standards in accordance with the paper scale ( CNS) A4 size (210X297 mm) 1 310971 523494 A7
