[0002] Autotrophic denitrification denitrification device is a sewage treatment technology that uses specific materials and microorganisms to remove nitrate nitrogen from wastewater. Autotrophic denitrification technology is a type of biological denitrification technology. Compared with heterotrophic denitrification technology, autotrophic denitrification does not rely on organic carbon sources. Therefore, it may be more applicable and economical when treating certain wastewaters containing limited organic carbon.

[0003] The existing autotrophic denitrification and denitrification device is not convenient for stirring the sewage, resulting in slow mixing and contact between the sewage and the reactants, reducing the efficiency of nitrogen removal, and is not convenient for replacing the reactants. When replacing the reactants, the tank body needs to be opened, which is very time-consuming and labor-intensive, reducing the practicality of the device. Therefore, we propose a new autotrophic denitrification and denitrification device to solve this problem. Utility Model Content
