Problems solved by technology

Some adopt the light source to be located in the center of the reactor, but the anode and the cathode are located on the top and bottom of the reactor shell and are vertical to the light source and the shell parallel to the light source, so there is nothing to do with it. For the anode of the reactor And the cathode is vertical, parallel with the light source and the housing and the photocatalytic reactor that the large reaction chamber is divided into 2-6 reaction chambers has not been reported

Abstract

The invention relates to a three-phase three-dimensional electrode photoelectric reactor and application thereof. The reactor comprises a reactor shell, a titanium metal net anode, a stainless steel or graphite cathode, a gas distribution board, a double-layer U-shaped quartz pipe as well as a light source UV (ultraviolet) lamp, a three-dimensional particle electrode and clapboards placed in the quartz pipe. According to the three-phase three-dimensional photoelectric reactor provided by the invention, a non-homogeneous three-dimensional electrode and a photocatalysis technique are ingeniously combined, not only are the oxidation of the anode and the reduction of the cathode utilized, but also the synergism of.OH, H2O2, -OH and other active substances generated by an electric field and photocatalysis are utilized, the surfaces of TiO2 particles are continuously renewed, and the reaction system is organically harmonized, thus the organic matter degradation reaction is more thorough, and the decolorizing rate in printing and dyeing wastewater treatment can reach 97.09%. A large reaction chamber is uniformly divided into 2-6 small reaction chambers by the clapboards, thus a group of 2-6 control experiments can be carried out under the reaction conditions of the same voltage, light source, reaction time and the like.

Description

technical field [0001] The invention relates to a three-phase three-dimensional photoelectric catalytic reactor, which is used for the treatment of refractory organic matter in laboratories. Background technique [0002] With the development of modern industry, the impact of organic wastewater on the environment is becoming more and more serious, especially the treatment of high-concentration organic pollutants is the difficulty and focus of industrial wastewater treatment in the world. Carey et al. reported that TiO 2 Photocatalytic oxidation has been successfully used for dechlorination of PCB compounds in water (Carey J H, Lawrence J, Tosine H M. Photodechlorination of PCB's in the presence of titanium dioxide in aqueous suspensions [J]. Bull1 of Environ Contam Toxicol, 1976, 16(6 ): 697-701), semiconductor heterogeneous photocatalysis has attracted extensive attention in the field of water treatment. with TiO 2 The application of heterogeneous photocatalysis as a phot...
