Abstract

The invention relates to an electrochemical method of hydrogen peroxide production. A solution saturated with pressurised oxygen is fed to a primary electrolyser wherein it is cathodically reduced. The electrolyte may consist of waste-water containing oxidisable organic substances or of an acidic solution in which product hydrogen peroxide is accumulated to be subsequently injected in waste-waters to be treated. The pressurised oxygen is either obtained by water electrolysis in a secondary electrolyser or by means of an air-separation device.
