Description

Technical Field

[0001] The utility model relates to the technical field of eel processing wastewater treatment, in particular to an eel processing wastewater filtering device. Background Art

[0002] The wastewater from eel slaughter contains impurities such as oil, gills, bubbles, blood clots, and thorns. The wastewater from eel slaughter has high chromaticity and is accompanied by a fishy smell, which gives people strong sensory discomfort. The wastewater contains a large amount of organic pollutants, and direct discharge will cause serious environmental pollution. Therefore, it is necessary to carry out reasonable treatment of slaughter wastewater.

[0003] The traditional eel sewage treatment is to add coagulants to the sewage to mix the sewage and coagulants, and then pass them through a flotation machine to further remove small suspended solids and oil pollutants. The traditional scum removal is to skim off the scum floating on the sewage surface with a scraper. Since the scraper height cannot be controlled, the scraper often fails to scrape the scum or scrapes the scum too superficially, greatly reducing the scum removal efficiency. Utility Model Content
