Photocatalysis and biological purification equipment

    Photocatalysis is a deep reaction technology at room temperature. Photocatalytic oxidation can completely oxidize organic pollutants in water, air and soil into non-toxic and harmless products at room temperature, while traditional high-temperature incineration technology requires extremely high temperatures to destroy the pollutants, that is, use Conventional catalysis and oxidation methods also require high temperatures of several hundred degrees. In theory, as long as the light energy absorbed by the semiconductor is not less than its band gap energy, it is enough to excite electrons and holes, and the semiconductor may be used as a photocatalyst. Common single compound photocatalysts are mostly metal oxides or sulfides, such as Ti0. , Zn0, ZnS, CdS and PbS etc. Each of these catalysts has outstanding advantages for specific reactions, and can be selected according to needs in specific research. For example, CdS semiconductor has a small band gap energy and has a good matching performance with the near-ultraviolet light band in the solar spectrum, and can make good use of natural light energy. , But it is prone to light corrosion and has a limited service life. Relatively speaking, TiO2 has better overall performance and is the most widely used and researched single compound photocatalyst. Processing principle Dilution diffusion method Principle: Exhaust odorous gas to the atmosphere through the chimney, or dilute with odorless air to reduce the concentration of odorous substances to reduce odor. Scope of application: It is suitable for the treatment of odorous gases with medium and low concentrations. Advantages: low cost and simple equipment. Disadvantages: easy to be restricted by weather conditions, and malodorous substances still exist.
