IPC: C02F1/46
Filed: 1997-03-24
Abstract: PROBLEM TO BE SOLVED: To improve an electrode exchange workability and a handling property for removing phosphorus by using plural electrode pairs using an iron material or aluminum at least anode in an elution device and connecting the electrode pairs to a power source in series. SOLUTION: An iron ion is eluted from the electrode 43 to a sewage made to flow to an elution tank by impressing a constant direct current between the electrodes 43 consisting of the iron material. The eluted bivalent iron ion is oxidized to tervalent to increase a dephosphorizing efficiency. The electrode may be constituted by using the aluminum other than iron. A weight of each electrode pair is reduced by providing plural pairs of the electrode 43, moreover, a handling is make more easy since the electrode pair is used as an electrode unit 38. And a current having same current value is supplied to each electrode 43 and each electrode 43 is uniformly reduced since each electrode 43 is connected to a power source device 42 in series. Therefore, each electrode 43 is exchanged simultaneously and a maintenance efficiency is increased.
