A waste water treatment method and apparatus comprising a waste water treatment chamber (4) with at least one set of electrodes (5,6) arranged so that at least a part thereof is immersed in the waste water. At least one of said electrodes (5,6) dissolving out, by electrolysis, iron ions or aluminum ions for precipitating and removing phosphoric acid ions in the waste water. A power source (7) for supplying an electrolytic current to the set of electrodes (5,6). A control unit (8) for controlling the power source and a metallic catalyst (9,10) disposed in the vicinity of at least the other of the set of electrodes which acts on the denitrifying reaction with hydrogen in the waste water. <IMAGE> |
