Plastic sheet embedded particle composite electrode and preparation method thereof

Abstract

The invention discloses a plastic sheet embedded particle composite electrode and a preparation method thereof. The plastic sheet embedded particle composite electrode is used for suspending in a reactor of a three-dimensional electrode, and comprises a plastic sheet playing a mounting and supporting role, wherein the plastic sheet is prepared from a plastic material and is a spatial curved surface sheet with a spatial curved surface, scattered and granular particles are embedded in the surface of the plastic sheet, the particles are used for mass transfer after being in contact with wastewater in a reactor, and the particles are connected with the plastic sheet to form a composite particle electrode. According to the plastic sheet embedded particle composite electrode, the plastic sheet is made of the plastic material, the resistance is high, the supporting effect of the plastic sheet on the particles is beneficial for preventing the particles embedded in the particles from being smashed due to pressure friction, and the particles are stably embedded in the plastic sheet; and the particles are mutually dispersed and insulated, so that each particle can fully exert the efficiency of the microbattery, the short-circuit current is greatly reduced, the current efficiency is improved, and the mass transfer and wastewater treatment effects are improved.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a particle-embedded composite electrode in a plastic sheet. In addition, the invention also relates to a method for preparing a composite particle electrode for preparing a composite particle embedded in a plastic sheet. Background technique [0002] Refractory organic wastewater is a hot and difficult point in the current industrial wastewater treatment. Electrocatalytic technology does not produce sludge, has no secondary pollution, mild reaction conditions, simple operation, and easy control of the reaction process. It has great application prospects, but due to low catalytic efficiency , low mass transfer efficiency, high energy consumption and other problems limit the application. The three-dimensional electrocatalytic technology fills the traditional two-dimensional electrocatalytic reactor with particle electrodes. The particle electrodes are polarized and charged when ele...
