High level pond culture system with separating pollution discharge

Abstract

The invention discloses a high level pond culture system with separating pollution discharge; the high level pond culture system comprises a culture pond, a discharge port, and a discharge pipe; the bottom of the culture pond is provided with the discharge port connected with the discharge pipe; the system also comprises a discharge increasing shield, an anti-escape shield, a dirt discharge facility and a circulation water discharge facility; the discharge pipe is respectively connected with the dirt discharge facility and the circulation water discharge facility through a tee joint; the discharge increasing shield and the anti-escape shield are arranged above the discharge port; the system singly discharges the sewage into a recover pond, and discharges culture water to another recover pond, so the sewage can be recovered, utilized and processed in s harmless mode, thus preventing secondary pollution of the pond sewage on the culture water; the high level pond culture system is low in cost, simple in operation, easy to promote, high in efficiency, and can provide important meaning 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 high-level pond culture system for separating sewage. Background technique [0002] With the improvement of people's living standards, aquatic products are more and more favored by people. Aquatic products such as fish, shrimp, crab, shellfish, etc. have gradually become indispensable delicacies on the table because of their delicious taste and high nutritional value. , greatly promoted the development of high-level pond aquaculture, the high-level tank circulating aquaculture model not only makes full use of land and water resources, but also reduces environmental pollution and greatly improves pond productivity. [0003] my country is the country with the largest aquaculture area and the highest output in the world. And with the continuous expansion of aquatic product aquaculture area, the coastal aquatic product aquaculture industry is growing day by day. Ho...

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
