[0002] Anaerobic ammonia oxidizing bacteria (ANAO) attachment packing devices play an important role in wastewater treatment and related fields. ANAOs are specialized microorganisms that can directly convert ammonia nitrogen and nitrite nitrogen into nitrogen gas under anaerobic conditions, achieving highly efficient nitrogen removal. Suitable packing devices can provide a favorable environment for their attachment and growth, thereby improving treatment efficiency.

[0003] The packing device is inserted into the wastewater, and the cavity allows microorganisms to attach and nourish, forming a biofilm. This biofilm then purifies the wastewater of ammonia nitrogen and nitrite nitrogen, achieving denitrification. However, existing packing devices are inconvenient to use in high-intensity wastewater aeration treatment. During aeration, the rapid flow of wastewater can easily cause the microbial biofilm within the packing device's cavity to detach, thus affecting the wastewater treatment efficiency and quality. Therefore, we propose a packing device that facilitates the attachment of anaerobic ammonia-oxidizing bacteria. Utility Model Content
