Embodiment
[0046] (1) The preparation process of a multi-dimensional electrode electrocatalytic device for removing various refractory organic pollutants is as follows:
[0047] The length of the electrolytic cell is 60mm, the width is 50mm, and the height is 120mm. A water outlet with an aperture of 2 mm is opened at a distance of 35 mm from the bottom on the center line of the side wall. A grid support is set at the four corners of the electrolytic cell at a distance of 10 mm from the bottom, and the grid support is formed by bonding cubes whose upper and lower dimensions are 5 mm and 10 mm respectively. The permeable grille is a thin plate with a length of 56mm, a width of 46mm, and a thickness of 3mm. The squares with a side length of 2mm are removed from the four corners of the permeable grille, and permeable holes with a diameter of 2mm are evenly opened on the permeable grille sheet. It is movable, can be taken out, and can be placed on the grid support when in use. The plate ca...

Abstract
The invention discloses a multi-dimensional electrode electrocatalysis device for removing various persistent organic pollutants, belonging to the technical field of electrochemical treatment of high concentrated organic wastewater. The device comprises an electrolytic tank, pole plate clamp slots, grid supports, a water permeable grid, a magnetic bead, a water outlet, a stainless steel cathode plate, a Pt supported, CoO-SnO doped and SrO film coated titanium base anode plate, wires, a stabilized voltage and current supply and Ag supported and CuO-CeO2 doped activated alumina particle electrodes containing NiO interlayers, wherein the magnetic bead is placed at the bottom of the electrolytic tank; the water outlet is formed in the middle lower part of the electrolytic tank; the grid supports are distributed at the four corners of the electrolytic tank; four pole plate clamp slots are placed in the electrolytic tank; five clamp positions are uniformly arranged on each pole plate clamp slot and are used for selecting proper space to insert the stainless steel cathode plate and the titanium base anode plate; finally the activated alumina particle electrodes are uniformly thrown in the gap between the cathode plate and the anode plate. The device has the beneficial effects that the device has high efficiency of treatment on wastewater containing various persistent organic compounds, is low in cost, and is simple to operate.
Description
technical field [0001] The invention belongs to the technical field of electrochemical treatment of high-concentration organic wastewater, and in particular relates to a multi-dimensional electrode electrocatalysis device for removing various refractory organic pollutants. Background technique [0002] Electrocatalytic oxidation technology degrades organic pollutants in wastewater by generating strong oxidizing active groups such as hydroxyl radicals. It has the characteristics of no secondary pollution, low cost, strong applicability, and high efficiency. It has application potential in degrading wastewater. In order to enhance the electrocatalytic treatment effect of refractory biodegradable wastewater, it is very critical to improve the effective reaction area per unit volume, mass transfer effect and current efficiency of the electrolytic cell. Therefore, it is necessary to develop a new type of high-efficiency electrocatalytic reactor. At the same time, it is one of th...
