Description

Technical Field

[0001] This utility model relates to the field of polyacrylamide flocculant feeding technology, specifically to a feeding device for polyacrylamide flocculant. Background Technology

[0002] Polyacrylamide flocculant is a water-soluble polymer that is widely used in water treatment, industrial production, and biomedicine.

[0003] Polyacrylamide flocculants can be classified into four types according to their ionic properties: anionic, cationic, nonionic, and amphoteric. When treating wastewater, it is necessary to select the type based on the charge properties of the suspended solids in the wastewater (e.g., cationic flocculants are used for negatively charged colloids).

[0004] When the wrong type is selected, such as using cationic polyacrylamide flocculant to treat anionic wastewater, or using polyacrylamide flocculant with mismatched molecular weight for specific wastewater, it is easy to lead to poor flocculation effect. Utility Model Content
