Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a treatment device for aquatic product processing wastewater. Background Technology

[0002] With the rapid development of the aquatic product processing industry, the amount of wastewater generated is increasing day by day. Aquatic product processing wastewater contains a large amount of organic matter, protein, oil, suspended solids, and nutrients such as nitrogen and phosphorus. If it is discharged directly without effective treatment, it will cause serious pollution to the aquatic environment, leading to problems such as eutrophication and water quality deterioration, threatening the survival of aquatic organisms and the ecological balance.

[0003] Currently, the aquatic product processing industry is booming, but the wastewater treatment situation is far from optimistic. Most aquatic product processing enterprises, for the sake of convenience, directly discharge wastewater, completely ignoring the pre-treatment stage. Even the few enterprises that are aware of the need for treatment mostly use the simple and primitive method of filtration. Aquatic product processing wastewater has a complex composition, containing not only a large amount of solid impurities such as fish and shrimp remains and internal organs, but also oils, proteins, and various microorganisms. These impurities easily adhere to and accumulate when passing through the filter screen, causing the filter surface to be quickly clogged. Once the filter screen is clogged, the wastewater treatment efficiency will be greatly reduced. At the same time, this treatment method does not take into account the sterilization treatment of the wastewater, so that the treated wastewater still contains a large number of pathogens. Direct discharge will cause serious harm to the surrounding aquatic environment and ecosystem, and cannot meet current needs. Utility Model Content
