Abstract

The invention provides an electrocatalytic oxidation decontamination device. The electrocatalytic oxidation decontamination device includes an electrocatalytic oxidation chamber, an aeration tank, a sedimentation tank, a slagging tank and a drainage tank, and the electrocatalytic oxidation chamber includes an anode electrode, a cathode electrode, a foam scraping system and a defoaming tank. The anode electrode includes a titanium substrate, a titanium suboxide intermediate layer and a cerium-lead dioxide layer, and the titanium suboxide intermediate layer is arranged between the titanium substrate and the cerium-lead dioxide layer. An electrocatalytic oxidation decontamination device provided by the present invention adopts the structure of spraying a titanium suboxide intermediate layer on the surface of the titanium substrate, so that the matching between the titanium substrate and the titanium suboxide is suitable, so that the interpenetration and interpenetration between the intermediate layer and the substrate appear. And the state, which slows down the passivation process of the matrix caused by the infiltration of oxygen atoms to a certain extent, and at the same time significantly enhances the bonding force between the intermediate layer and the matrix, and the electrocatalytic effect is good.

Description

technical field [0001] The invention relates to the field of decontamination equipment, in particular to an electrocatalytic oxidation decontamination device. Background technique [0002] Electrocatalytic oxidation of wastewater can be applied to remove a variety of pollutants, and can recover precious metals in wastewater. Electrocatalytic oxidation wastewater treatment has the advantages of simple equipment, easy control, simple post-treatment, small footprint, and sludge volume. The anode electrode in the existing electrocatalytic oxidation decontamination device is prone to passivation, which affects the catalytic effect of the electrode and the service life of the decontamination device. There are foams on the upper part of the electrocatalytic oxidation tank and sediment at the bottom, and the pollutant treatment effect is not good. Well, it affects the working efficiency of the equipment. Contents of the invention [0003] In order to solve the technical problems...
