Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, in particular to aquaculture tail water treatment and utilization technology. Background Art

[0002] The flesh of the baby snail is delicate and delicious, boasting the benefits of cooling blood, stopping bleeding, and nourishing yin and moistening dryness. Rich in protein, vitamins, essential amino acids, and trace elements, it is a typical natural animal-based health food, high in protein, low in fat, and high in calcium. In recent years, baby snails have become a popular high-quality marine shellfish in both domestic and international markets, leading to the growing scale of baby snail farming along China's southeastern coast. The annual production of baby snails reaches 6 billion seedlings and 15,300 tons, generating a direct output value of approximately 2 billion yuan. It plays a significant role in driving rural revitalization and promoting social development. However, this vigorous development of baby snail farming also comes at the cost of negative environmental impacts. Traditional baby snail farming primarily utilizes a flow-through system in cement ponds. To ensure clean water quality, water exchanges are at least eight times the pond capacity. Discharged water contains large amounts of environmentally unfriendly pollutants such as leftover bait, feces, ammonia nitrogen, and pathogenic microorganisms. In order to promote the green, healthy and sustainable development of the conch farming industry, it is necessary to develop a tailwater treatment technology that can save water and effectively treat tailwater pollutants without affecting the quality of the water body for conch farming.

[0045] The working principle of this utility model is as follows:

[0046] The tail water of the Dongfeng snail aquaculture is extracted by the tail water treatment pump 10 and enters the Dongfeng snail circulating water aquaculture tail water multifunctional treatment device tangentially from the tail water inlet end 2. At the same time, combined with the guidance of the first cone 61, the water swirls in the second cone 62. The foam generated in the swirl process carries the pollutants and rises to the inner cylinder 3, and then forms dense and uniform foam through the gap between the second air distribution member 33 and the inner cylinder 3 and continues to rise. The foam and water falling into the second air distribution member 33 will flow down from its through holes. The foam passes through the foam channel to form uniform foam of about 30-50 mm and continues to rise. The foam and water falling into the first air distribution member 4 will flow down from its through holes. The foam rising through the foam channel is finally discharged to a designated place through the buffer tank 51, the foam collection pipe 52, the foam collection tank 53, and the foam discharge pipe 54. The water that rises to the inner cylinder 3 following the foam flows from the gap between the second air distribution member 33 and the inner cylinder 3 to the water outlet channel 13, and flows from the water outlet 11 of the foam separator to the water outlet main pipe 6 for discharge or return to the Dongfeng snail aquaculture pond;

[0047] The water after the vortex in the second cone 62 still contains suspended matter and semi-suspended matter, which then enters the multifunctional aquaculture tailwater treatment device tangentially through the drain pipe 63 and the inverted U-shaped water pipe 8. At the same time, combined with the guidance of the first frustum 71, the water body generates a vortex. The supernatant water of the vortex in the second frustum 72 rises into the first frustum 71, flows through the outlet 12 of the secondary vortex sedimentation component to the outlet main pipe 6 for discharge or returns to the baby snail breeding pond, and the gas is discharged from the exhaust hole of the first frustum 71. The suspended matter, semi-suspended matter and other pollutants that sink in the vortex in the second frustum 72 gradually settle into the collection well 73 and are discharged to the designated place through the sewage pipe 74 at a regular interval by the electric ball valve 742;

[0048] The jet pump 23 extracts a portion of the water and makes it enter the inner tube 3 through the ejector 232. The ozone provided by the ozone supply device is sucked into the ejector 232 due to the negative pressure, and the air and water are mixed and enter the inner tube 3.

[0049] When the water in the drain pipe 63 needs to be discharged, the normally closed valve 632 is opened and the water can be discharged to a designated place through the sewage pipe 74. The concentrated tail water collected by the foam discharge pipe 54 and the sewage pipe 74 can be discharged or recycled after sedimentation filtration, filter-feeding fish purification, aquatic plant purification and microbial purification meet the standards.

[0050] Normally open valve 631 and manual ball valve 741 are spare for special circumstances.

[0051] The technical solution of this embodiment can recycle 90% of the water in the conch breeding pond, reduce the seawater consumption by 90% and the discharge of aquaculture tail water by 90% compared with traditional flow-through aquaculture, and save energy by 33.6%; it changes the previous mode of direct discharge of conch breeding tail water, and only needs to supplement 10% of sea water, which greatly saves water resources; seawater supplementation can increase the trace elements required by conch and accelerate the growth rate; after treatment, seawater and tail water can be directly supplied to the breeding pond, reducing the investment in auxiliary equipment and alleviating the burden on farmers; ozone can be used to disinfect the water body and treat water-soluble organic matter; after treatment, the aquaculture tail water not only has the water quality significantly improved, such as the pollutant indicators such as suspended solids, COD, total nitrogen and total phosphorus are reduced by more than 50%, meeting the discharge requirements, but also does not carry pathogens such as Vibrio and parasites, which is conducive to reducing the spread of diseases and improving the survival rate and success rate of conch breeding.

Specific examples are used herein to illustrate the principles and implementation methods of the embodiments of the present invention. The description of the above embodiments is only applicable to help understand the principles of the embodiments of the present invention.
