Seawater circulation culture system with circulation water treatment

Abstract

The invention discloses a seawater circulation culture system with circulation water treatment; the seawater circulation culture system comprises a culture pond, a sewage discharge port, a sewage discharge pipe; the bottom of the culture pond is provided with the sewage discharge port connected with the sewage discharge pipe; the system also comprises a sewage discharge mechanism and a circulation water discharge mechanism; the sewage discharge pipe is connected with the sewage discharge mechanism and the circulation water discharge mechanism through a tee joint; the circulation water discharge mechanism is connected with a circulation water processing mechanism comprising an oxidation water reservoir, a primary biological cleaning pond and a micro-ecology cleaning pond; tail water is discharged into the oxidation water reservoir through the circulation water discharge mechanism, fully oxidized and settled, and enters the primary biological cleaning pond; the water is cleaned by the biological cleaning pond and enters the micro-ecology cleaning pond for micro-ecology treatment; the water will be reused after water quality reaches the standards, thus realizing culture water full circulation usage. The seawater circulation culture system is low in cost, simple in operation, easy to promote, high in efficiency, and can provide important meanings for protecting sea environment and aquatic product safety production.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a seawater circulation aquaculture system with circulating water treatment. Background technique [0002] With the improvement of people's living standards, aquatic products are more and more popular among people. Aquatic products such as fish and shrimp have gradually become indispensable delicacies on the table because of their delicious taste and high nutritional value. With the development of high-level pond aquaculture, the high-level pond recirculating aquaculture model not only makes full use of land and water resources, but also reduces environmental pollution and greatly increases pond productivity. [0003] my country is the country with the largest aquatic product breeding area and the highest output in the world. And with the continuous expansion of aquatic product breeding area, the coastal aquatic product breeding industry is growing day by day. How...

AI Technical Summary

Problems solved by technology

[0004] At present, in the high-level pond aquaculture industry of aquatic products in coastal areas, although some enterprises try to adopt the circular aquatic product aquaculture model, they often discharge the sewage and aquaculture tail water directly into the sea when discharging sewage and changing water, which makes toxic and harmful algae, Bacteria and viruses reproduce in large numbers and are difficult to control, which seriously deteriorates the breeding environment and pollutes the circulating water, increases the difficulty and cost of recycling water treatment, affects the water treatment effect, causes the breeding environment and benefits to be unstable, and the discharged pond sewage is harmful to the ocean. The environment is seriously polluted, which is not conducive to the recycling of seawater and cannot guarantee the safe production of aquatic products
