Description

A circulating water treatment system and a filter device with a cam driving mechanism

technical field

The invention relates to the field of aquaculture, in particular to a circulating water treatment system and a filter device with a cam driving mechanism.

Background technique

In the process of aquaculture in ponds, water quality control often changes the water in large quantities to improve the pond water. This is because during the aquaculture process, the aquatic products in the pond will consume a large amount of oxygen in the water, and will also produce a large amount of metabolites, especially for ponds with high-density aquaculture. In addition, the bottom of the pond will also deposit residual bait and feed that has not been eaten by aquatic products. These residues and metabolites will lead to eutrophication of water bodies and cause the growth of parasitic microorganisms. Therefore, after a period of cultivation, the water body in the pond will not be suitable for aquatic growth. If the exchanged water is discharged directly without treatment, it will also damage the local environmental ecosystem. Therefore, the preferred solution is to purify the exchanged water and then discharge it into the original pond.

To sum up, it is necessary to design a water treatment device to treat the water exchanged in the pond, filter out impurities in the water (such as fish feces and residual bait feed), and be able to oxygenate the water.
