Abstract (en)
[origin: WO2015127918A1] The invention relates to a method for oxidative breakdown of nitrogenous compounds in waste water by means of an electrochemical treatment using a diamond electrode as an anode (A) and a cathode (K) as a counter-electrode, wherein the destruction of the nitrogenous compounds and a reduction of the total nitrogen content can be achieved in a common method in that, in a first method step, a first current density is adjusted on the anode (A) in order to oxidize the nitrogenous compounds and subsequently, by means of a second current density which is smaller than the first current density, the dissolved total nitrogen content is reduced by releasing molecular nitrogen.
