Description

Technical Field

[0001] The utility model relates to the technical field of refractory organic matter treatment equipment, and specifically, to a catalytic oxidation treatment equipment for refractory organic matter. Background Technique

[0002] Refractory organic matter refers to a class of organic compounds that are difficult to be effectively decomposed under natural environment or conventional biological and chemical treatment conditions. Such organic matter usually has a complex chemical structure, high toxicity to microorganisms, or its molecular structure is stable and difficult to be destroyed by biological enzymes or other degradation mechanisms. With the acceleration of industrialization and urbanization, the emissions of refractory organic matter increase year by year, causing serious pollution to the environment such as water bodies, soil and air, and posing a great threat to the ecosystem and human health.

[0003] When performing traditional treatment operations on refractory organic matter, it mainly includes biological treatment, physical adsorption and chemical oxidation, etc. However, the above methods are difficult to perform rapid treatment operations to render refractory organic matter harmless, affecting the treatment effect. At present, in order to achieve a harmless treatment effect, catalytic oxidation treatment operations are usually carried out on refractory organic matter. Catalytic oxidation treatment can decompose refractory organic matter into water, carbon dioxide, etc., achieving harmless treatment.

[0004] When performing catalytic oxidation treatment operations, corresponding catalytic oxidation treatment equipment is usually used. There are many types of catalytic oxidation treatment equipment on the market. Most catalytic oxidation treatment equipment directly uses pipelines to introduce air into the tank for oxidation treatment operations, and the end of the pipe body is generally installed at the top position of the tank. Since refractory organic matter basically accumulates at the bottom of the tank, at this time, it is difficult to ensure that the refractory organic matter is fully in contact with air, affecting the catalytic oxidation effect. In view of this, we propose a catalytic oxidation treatment equipment for refractory organic matter. Content of the Utility Model
