Water purification system and purification method for seafood pool

Abstract

The invention relates to the technical field of circulating water treatment for temporary culture of aquatic products, and discloses a water purification system of a seafood pool. The system comprisesa front filter barrel, a circulating water pump, a constant temperature machine, an ozone supply device and an air flotation device which communicate with one another in sequence, and connecting pipelines for connecting the above parts; the air flotation device is connected with the circulating water pump; the front filter barrel is connected with a temporary culture pond, a system water inlet valve is arranged at the joint of the front filter barrel and the temporary culture pond, the constant temperature machine is connected with the temporary culture pond, and a system water outlet valve is arranged at the joint of the constant temperature machine and the temporary culture pond; the lower ends of the front filter barrel and the air flotation device are connected with a drain outlet; and a first cleaning valve is arranged at the joint of the lower end of the front filter barrel and the drain outlet. The invention has the beneficial effects that the ozone supply device ensures sufficient introduction of ozone, and when an ozone generator stops working, the air flotation device starts to work, so that the pollution discharge capacity of the air flotation barrel is enhanced; and the intelligent ozone supply device and the intelligent air flotation device are used in cooperation in the whole process, and the dissolved oxygen level of the water body is greatly improved.

Description

technical field [0001] The invention relates to the technical field of circulating water treatment for temporary cultivation of aquatic products, in particular to a water purification system for seafood ponds. Background technique [0002] The water treatment system in the existing seafood sales industry usually uses one or a combination of the following methods to treat the water body: [0003] 1. Wound-type filter tank: Multi-grid filter tank is designed, and filter materials such as sponge and coral stone are respectively placed to filter particles visible to the naked eye; the wound-type design limits the amount of gas introduced. [0004] 2. Biochemical decomposition: use microorganisms to decompose harmful substances in the water body; this method has slow actual effect in the temporary cultivation of seafood sales and has no practical value. [0005] 3. Ultraviolet light sterilization: This method is only effective for the water passing through it and has limitations...

AI Technical Summary

Problems solved by technology

[0004] 2. Biochemical decomposition: use microorganisms to decompose harmful substances in water; this method is slow in actual effect in seafood sales and temporary cultivation, and has no practical value

[0005] 3. Ultraviolet lamp sterilization: this method is only effective for the water passing through it, with limitations

[0006] 4. Ozone-assisted sterilization: Ozone is introduced into the protein separator to treat water quality. Because the protein separator is working when the ozone is introduced into this method, there are shortcomings such as insufficient ozone introduction, short contact time between ozone and water, and inability to remove harmful substances in the water. plate

[0007] The temporary storage of aquatic products in the seafood sales industry is high-density temporary storage. Using one or more of the above solutions cannot quickly and effectively purify the water in this high-density temporary storage tank, and it is difficult to support high-density temporary storage of aquatic products.
