Application of Ozone Destruction Catalyst in Ozone Oxidation Process of Sewage Treatment Plant

In sewage treatment plants, usually the last process is ozone contact oxidation. The high-concentration ozone output by the ozone generator is aerated into the sewage and enters the contact oxidation tank for further deep oxidation. In this process, a large amount of ozone overflows from the water, and the air in the pool needs to be pumped out in time by a fan to form a negative pressure to prevent the ozone from escaping.

The concentration of ozone coming out of the contact pool is high and cannot be discharged directly, otherwise it will cause a series of impacts such as air pollution, severe odor, corrosion of peripheral equipment, personnel poisoning, and biological poisoning. Ozone tail destruction equipment is usually used to decompose ozone into oxygen and then emit it.

The ozone tail destruction system mainly includes four parts: demisting device, heating device, catalyst, and fan. The structure is relatively simple, but the ability to decompose ozone is very strong. Using the characteristics of the catalyst to decompose ozone at room temperature can save a lot of energy.

However, the catalyst has a lifespan. The lifespan of the ozone-destroying catalyst is affected by the quality of the catalyst itself and the operating conditions. The normal lifespan of the catalyst varies with the quality of the products of each manufacturer. Choosing a good ozone destruction catalyst can greatly prolong the life of the catalyst. Use time and save the cost of replacing the catalyst.
At the same time, in the daily operation of the water plant, it is also necessary to closely monitor the effectiveness of the demisting device and the heating device. Once there is a problem with these two devices, it will directly cause catalyst poisoning and cause the catalyst to fail prematurely. This is the main reason most water plant catalysts are replaced early.
