Analysis of the causes of failure of ozone destruction catalysts in sewage treatment plants

Ozone has a wide range of uses. It is used in most sewage treatment processes to disinfect and sterilize water before discharge, further reducing COD and meeting discharge standards.

An ozone destroyer is installed above the ozone contact reaction pool to decompose excess ozone and prevent environmental pollution. The most important part of the ozone destroyer is the ozone destruction catalyst, which can decompose ozone into oxygen.

Ozone destruction catalysts are usually a mixture of some metal oxides, which can be easily invaded by pollutants and cause poisoning. During the working process, the catalyst will be exposed to a large amount of water vapor. Before the very humid gas enters the catalyst, it will first pass through the condenser, demister, and heater, and finally enter the catalyst for decomposition. The condenser and demister will remove most of the liquid in the gas to prevent pollutants carried in the liquid from entering the catalyst. Then the heater heats the gas to a temperature higher than normal temperature to prevent the gas from condensing in the catalyst bed. The catalyst can work under good working conditions and its life will be longer.

The premature failure of ozone destruction catalysts is an important problem that plagues sewage treatment plants. This is usually caused by our lack of attention to ozone destruction catalysts and incorrect use. The main reasons are as follows:

1. The contact pool design is unreasonable.
2. The gas treatment process design is unreasonable.
4. The installation of each unit equipment is unreasonable.
5. The catalyst quality is poor, the activity is low, and the content of effective ingredients is low.

As a professional ozone depletion catalyst factory, MINSTRONG has rich experience in the research and development and manufacturing of ozone depletion catalysts. It can help users of water treatment plants use catalysts correctly and reduce the risk of premature catalyst failure.
