Ozone catalytic oxidation system

Non uniform ozone catalytic oxidation is an important branch of advanced oxidation water treatment technology, which is mainly achieved through direct and indirect reactions. It oxidizes large molecules and difficult to biodegrade organic matter into low toxicity or non-toxic small molecule substances, improving the treatment effect of subsequent biochemical methods.

Ozone has a high standard oxidation-reduction potential (207V) and is widely used for the oxidation treatment of organic compounds. However, the reaction between ozone and organic matter is selective, resulting in lower efficiency of ozone oxidation alone. In order to overcome the limitation of selective reaction between ozone and organic compounds, a new type of ozone catalyst has been developed, which can increase the production of hydroxyl radicals by 300% and significantly enhance the oxidation ability of ozone. The oxidation-reduction potential of hydroxyl radicals is higher (280V), and their reaction with organic compounds is not selective, resulting in a faster reaction rate. It can better remove organic matter from wastewater.

The surface and internal cavities of the catalyst can adsorb and enrich ozone in water, increasing the local concentration of ozone. Through catalytic action, the conversion efficiency of ozone to hydroxyl radicals is increased, greatly increasing the concentration of hydroxyl radicals, resulting in significant reaction effects, faster reaction rates, and more thorough and complete degradation of organic matter.

Product Details

(1) Multiphase catalysts have a strong ability to capture and enrich ozone molecules. By modifying the surface of multiphase catalysts, they can have a large specific surface area and excellent particle hole activity, thereby enhancing their ability to capture, enrich, and adsorb ozone in water.

(2) The surface and pores of multiphase catalysts capture and enrich ozone in water, increasing local ozone concentration, catalyzing ozone production, and greatly increasing the concentration of hydroxyl radicals. The non selectivity and high efficiency of hydroxyl radicals have been utilized to improve the degradation efficiency of organic pollutants in the system.

(3) Through the catalytic action of multiphase catalysts on ozone, oxidative decomposition reactions occur. The homogeneous sintering inside and on the surface of multiphase catalysts contains highly efficient active components. Ozone molecules are more likely to form hydroxyl radicals under the action of the catalyst, and recalcitrant organic matter in wastewater is more easily adsorbed onto the active sites of the catalyst, undergoing oxidative decomposition reactions with the support of energy provided by ozone and hydroxyl radicals.

(4) No medication added, no sludge generated, no secondary pollution. Ozone multiphase catalytic oxidation technology does not require the addition of chemicals, produces no sludge, does not cause secondary pollution, has a catalyst life of more than 6 years, and is responsible for recycling by the manufacturer.

(5) The ratio of ozone dosage to COD removal is 1:2;

(6) Realize equipment, labeling, and serialization;

(7) based on automatic control technology, the operation process has been optimized

(8) The new catalyst has good wear resistance, high strength, and a large specific surface area (70000cm/g)
