<p>PROBLEM TO BE SOLVED: To provide a sewage treating device capable of continuously treating sewage without suspending the elution of a metal ion for forming a water-soluble phosphate and not needing special maintenance. SOLUTION: This sewage treating device D1 is provided with a sewage storage tank 21, a set of electrodes 2 and 3, a DC power source 4, electrode supporting parts 5 and 6 and electrode supplying parts 7 and 8. The sewage to be treated is stored in the tank 1. Both of the electrodes 2 and 3 are a rolled iron sheet. The one-end sides of the electrodes 2 and 3 are wound on the electrode casings 9 and 10 of the electrode supplying parts 7 and 8 so that the electrodes 2 and 3 are moved toward the other-end sides and the other-end sides of the electrodes are vertically dipped in the sewage in the tank 1. The electrodes 2 and 3 are supported by the electrode supporting parts 5 and 6 and delivered toward the other end sides by a supplying motor.</p> |
