Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture tail water treatment, in particular to a pond aquaculture tail water filtering device. Background Art

[0002] In pond farming, in order to increase farming output and pursue economic benefits, a centralized intensive farming model with high stocking density and high feeding amount is generally adopted. Traditional high-density aquaculture methods will cause a large amount of residual bait and feces to be discharged into the water body, resulting in eutrophication of the breeding pond water. If it is not treated in a timely and effective manner, it will not only deteriorate the breeding water environment, but also cause diseases in farmed animals such as fish, shrimp, and crabs, and reduce the quality and output of farmed products. In addition, the untreated breeding tail water discharged into the external river will have a certain negative impact on the natural water environment.

[0003] However, when treating aquaculture tail water, the existing aquaculture tail water filtering and treatment device usually uses a filter net to filter and separate the aquaculture tail water. During the long filtration process, leftover bait and feces are easily accumulated on the surface of the filter net, causing the filter net to be blocked. The staff needs to take out the filter net to clean it, which is not only time-consuming and labor-intensive, but also affects the progress of the aquaculture tail water work. Utility Model Content
