Abstract
Die Erfindung bezieht sich auf das Gebiet der Abwasserreinigung unter Verwendung loeslicher Elektroden und kann zur Abwasserreinigung auf Schiffen angewendet werden. Das Verfahren umfasst die Zufuhr der Abwaesser als Parallelstroeme in den Anoden- und Katodenraum der Diaphragmaelektrolysezelle unter Verwendung loeslicher Elektroden unter nachfolgender Durchmischung. Vor der Zufuhr in den Anoden- und Katodenraum der Elektrolysezelle mit den loeslichen Elektroden wird der Strom im Anodenraum bzw. Katodenraum der Diaphragmaelektrolysezelle mit den unloeslichen Elektroden behandelt, bis der p H-Wert des Anolyten 3,0...3,5 und der p H-Wert des Katolyten 10,1...10,6 erreicht.The invention relates to the field of wastewater treatment using soluble electrodes and can be applied to wastewater treatment on ships. The method comprises supplying the effluents as parallel streams into the anode and cathode compartments of the diaphragm electrolysis cell using soluble electrodes with subsequent mixing. Before being fed into the anode and cathode compartments of the electrolysis cell with the soluble electrodes, the current in the anode compartment or cathode compartment of the diaphragm electrolysis cell is treated with the non-soluble electrodes until the p H value of the anolyte reaches 3.0 p H value of the catholyte reaches 10.1 ... 10.6.
