PROBLEM TO BE SOLVED: To realize a wastewater treatment apparatus capable of removing a phosphorus component contained in a wastewater by electrolyzing the wastewater using an electrode material in which metal ions are dissolved. SOLUTION: The wastewater treatment apparatus is equipped with a treatment tank 11 into which wastewater is introduced, first and second electrodes 12 and 13 comprising a conductive metal arranged in the treatment tank 11 and a voltage impressing means 15 for impressing DC voltage to the first and second electrodes 12 and 13. Voltage is impressed across the first and second electrodes 12 and 13 by the voltage impressing means 15 to electrolyze the wastewater to dissolve metal ions in the treatment tank 11 from the first and second electrodes 12 and 13 to dissolve metal ions in the treatment tank 11 from the first and second electrodes 12 and 13 not only to modify wastewater so as to make alkaline but also to flocculate a phosphorus component in wastewater. By this constitution, the phosphorus component can be removed. COPYRIGHT: (C)2004,JPO
