The high-efficiency ozone dissolved gas device is composed of a Venturi mixer and a series of valves and fittings, and is controlled by PLC. It not only improves the degree of automation, but also greatly improves the oxygen conversion rate. Compared with traditional aeration equipment, the oxygen conversion rate is increased to more than 90%. This greatly saves the waste of ozone generator output. All pipes and accessories of this equipment are made of 316L material, which has a longer service life and higher safety.

Ozone Catalytic Oxidation Reactor Ozone Catalyst Ozone Generator
Technology of high efficiency catalytic oxidation of ozone
Catalytic ozone oxidation (OZO) is an efficient advanced wastewater treatment technology and has become a hot topic in the field of wastewater treatment in recent years. Compared with ozone as a single oxidant, ozone formed under the action of catalyst has a higher reaction rate with organic matter and stronger oxidation, which can oxidize almost all organic matter. Catalysts can use the strong oxidation of ozone to directly oxidize organic matter in water to CO2 and H2O, or decompose large organic molecules into small molecules, so that it is easier to be degraded.
Technological advantage of high efficiency catalytic oxidation of ozone
(1) The composite porous high-strength silica-aluminum catalytic carrier is not easy to lose the catalytic components, improving the stability of the catalyst. The carrier is prepared by special preparation technology, which has high mechanical strength and long service life.
(2) Carefully screen the carrier and active component of the catalytic filler, and use transition metals, rare metals and rare earth metals as effective catalytic components to ensure continuous and efficient ozone oxidation efficiency.
(3) A variety of catalytic components to strengthen the adaptability of the catalyst to different wastewater while improving catalytic activity.
(4) No loss of catalytic filler, no need to add regularly.
(5) It can catalyze the self-decomposition of ozone in water and increase the concentration of ·OH produced in water, so as to improve the effect of ozone oxidation, and the oxidation efficiency is 2 ~ 4 times higher than that of pure ozone oxidation.
(6) The activation energy of the reaction can be reduced or the reaction process can be changed, so as to achieve the purpose of deep oxidation and maximum removal of organic pollutants.
INTRODUCTION -- Catalytic oxidation of ozone
High-strength silicon-aluminum composite is used as a carrier, containing a variety of precious metals and transition metals, supplemented by rare metals as dispersants, and is prepared through multiple precision processes.It has remarkable characteristics such as high efficiency, high strength and long life. It ensures high-efficiency catalytic oxidation of most wastewater while increasing the ozone utilization rate by more than 50%. It is an ideal catalyst for the new generation of ozone catalytic oxidation.
