Description

Technical Field

[0001] The utility model relates to the technical field of sewage denitrification and dephosphorization, in particular to a feeding device for sewage denitrification and dephosphorization. Background Art

[0002] The denitrification phosphorus removal process is a process that uses the biological reaction process of nitrification-denitrification to remove nitrogen and phosphorus elements from sewage to prevent eutrophication of water bodies. In the denitrification phosphorus removal process, chemical reagents need to be added to the sewage to precipitate the phosphorus ions in the sewage, thereby achieving the purpose of phosphorus removal.

[0003] Traditionally, chemical reagents are added to sewage pools by manually sprinkling them into the pool, which is time-consuming and laborious, and increases labor costs. Some existing methods inject chemical reagents into sewage pools through feed pipes, but since the feed pipes are fixed and difficult to move, chemical reagents can only be added to the same position in the sewage pool, making it difficult for the chemical reagents to fully contact with the sewage. It is not convenient to add chemical reagents at different addition points, and they may need to be stirred manually, resulting in poor feeding effects. Utility Model Content
