Abstract
The utility model discloses a device for purification treatment, container, a gas diffusion electrode, an electrolysis electrode and a power supply unit including a holding liquid. The lateral wall of container is equipped with an opening. Gas diffusion electrode sets up on being equipped with the open-ended lateral wall, with sealed opening. Gas diffusion electrode is the electrically conductive material of porosity, and its one side towards the container has a hydrophobicity and a catalyst layer on coating this, and the another side has during the gas permeability gets into gas diffusion electrode for the outer oxygen of container. The electrolysis electrode sets up in the container. The one end electrical property of power supply unit is coupled to gas diffusion electrode, and other end electrical property is coupled to the electrolysis electrode, with electrolysis liquid. The oxygen that gas diffusion electrode enabled to enter into in the container combines with the hydrogen ion that the liquid electrolysis produced to generate hydrogen peroxide. The catalyst layer can with the hydrogen peroxide catalytic oxidation that generates in order to produce hydrogen oxyradical, use purification liquid.
