Photoelectric catalysis degrading organic reactor with swivel disc loaded with catalyst and degrading method

Abstract

The invention discloses a reactor for photoelectrocatalysis degradation of organic compounds using a rotary table supported with a catalyst, and a method for degrading the organic compounds by the reactor. The reactor comprises a rotary table supported with a photo-electro catalytic activity catalyst as the anode of the reactor, a motor driving the rotary table to rotate, a conductive granular activated carbon which can electrically catalyze the oxygen to generate hydrogen peroxide as the cathode, an ultraviolet or visible light source arranged in the reactor. The hydrogen peroxide generated from the activated carbon cathode forms hydroxyl radical under the action of the ultraviolet and degrades the organic compounds around both the anode region and the cathode region; the application of the rotary table avoids the light adsorption of the solution and accelerates the transfer of oxygen in the solution, which obviously improves the catalysis degradation efficiency of the refractory organic compounds.

Description

technical field [0001] The invention relates to a turntable photoelectric synergistic catalytic reactor for degrading organic pollutants and a method for degrading organic pollutants in solution by using the photoelectric synergetic catalytic reactor. Background technique [0002] With the rapid development of the economy, the traditional biochemical and chemical methods of wastewater treatment can no longer meet the needs of economic development. In recent years, many novel processing technologies have emerged, among which TiO 2 The nano-semiconductor photocatalytic treatment of wastewater technology represented by the nano-semiconductor has become a research hotspot, and it is also a technology with the most industrial application prospects. [0003] Light activates the photogenerated holes on the valence band of the semiconductor. Due to the strong oxidative properties of the photogenerated holes, the photocatalytic oxidation method, such as titanium dioxide, has a poten...

Problems solved by technology

[0007] For general supported catalysts, the light needs to pass through the solution to reach the surface of the catalyst. The solution, especially the colored solution, absorbs light, which seriously affects the catalytic degradation effect.
