Abstract

A porous titanium ozone aerator with ozone heterogeneous catalysis and electrocatalytic functions is disclosed, and the porous titanium ozone aerator comprises a porous titanium substrate and a catalytic layer loaded on the substrate. The catalyst layer is an oxide of Ti, Mn, Ce, Cu, Fe, Ni, Sn, Sb, Pb and the like or a composite of the metal oxides, and the oxide morphology can be nanoflowers, nanowires, nanorods and nanotubes. The porous titanium ozone aerator gives ozone ozone heterogeneous catalysis and electrocatalysis synergistic catalysis capability, and can achieve efficient catalytic reaction of gas, solid and liquid three phases of pollutants in the aerator to reach the object of high mineralization and removal of target pollutants. The porous titanium ozone aerator is used for drinking water treatment, wastewater treatment and other occasions using the ozone, and has the characteristics of strong oxidation ability, fast reaction speed, stable treatment effect, long service life, low investment, wide application scope, and the like, and has good application prospects.

Description

[0001] The present invention relates to a porous titanium ozone aerator with both ozone heterogeneous catalysis and electrocatalysis functions, in particular to a porous titanium ozone aerator loaded with a catalytic coating and simultaneously having ozone heterogeneous catalysis and electrocatalysis functions device. Through the synergistic catalytic effect of the catalyst, the gas-liquid-solid three-phase catalytic reaction can be effectively realized on the surface of the porous titanium aerator, and the decomposition of target pollutants in wastewater can be promoted. The invention belongs to the field of ozone aerator technology in water treatment process. Background technique [0002] Ozone has been widely used in fields such as sterilization, decolorization, degradation of organic matter, deodorization and deodorization. In addition, the treatment of target pollutants by ozone is mainly through direct oxidation reaction. Usually, direct reaction refers to the direct re...
