Seawater circulation culture system with sewage disposal facility

Abstract

The invention discloses a seawater circulation culture system with sewage disposal facilities; the seawater circulation culture system comprises a culture pond, a disposal port, a disposal pipe; the bottom of the culture pond is provided with the disposal port connected with the disposal pipe; the system also comprises a sewage discharge facility and a circulation water discharge facility; the disposal pipe is respectively connected with the sewage discharge facility and the circulation water discharge facility through a tee joint; the sewage discharge facility is connected with a sewage processing facility comprising a sewage settling pond and a biological cleaning pond connected in sequence; the system gathers sewage in one recovery pond, and discharges culture water into another recovery pond, so sewage can be conveniently recovered, utilized and processed in a bio-safety way, thus preventing pond sewage from polluting the culture water for a second time; the 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 sewage treatment facilities. 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, shrimp, crab, and shellfish have gradually become indispensable delicacies on the table because of their delicious taste and high nutritional value. , has greatly promoted the development of the high-level pond aquaculture industry. 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 pro...

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
