Problems solved by technology

[0003] However, with the expansion of Penaeus vannamei aquaculture scale and the improvement of aquaculture density, problems such as environmental pollution and economic constraints are becoming more and more serious, which greatly limits the development of aquaculture industry.
Especially in the intensive aquaculture process, a large amount of residual bait and feces are discharged into the aquaculture water body, causing the rapid accumulation of toxic substances such as ammonia nitrogen, resulting in the deterioration of the aquaculture water quality and potential environmental pollution.

Embodiment 1

[0021] Embodiment 1 Construction of spiral zero discharge Penaeus vannamei culture system

[0022] (1) The spiral zero-discharge Penaeus vannamei culture system can be constructed on a site with a natural slope or on a flat site.

[0023] (2) Determine the construction site of the spiral zero-discharge Penaeus vannamei culture system, and determine the elevation of each structure in the system. The width of pool I (1), pool II (3) and pool III (5) is 2.0 meters, and the top elevation is the same, all of which are 2.6 meters; the bottom is inclined from the beginning of pool I (1) to the end of pool III (5). The slope is 4%, the bottom elevation of the beginning of pool I (1) is 0.6 meters, and the bottom elevation of pool III (5) is 0.0 meters;

[0024] (3) Determine the elevation of the retaining weir (7), sedimentation tank (8), overflow weir (9), purification tank (10) and permeable weir (12). The retaining weir (7) is 2.0 meters wide, and the bottom is 200mm high to open...

Abstract

The invention discloses a spiral zero-discharge litopenaeus-vannamei breeding system. The spiral zero-discharge litopenaeus-vannamei breeding system is composed of a first pond (1), a first separating net (2), a second pond (3), a second separating net (4), a third pond (5), a flow stopping weir (7), a settling pond (8), an overflow weir (9), a purifying pond (10), purifying plants (11), a permeable weir (12) and an air-lifting backflow device (13). The air-lifting backflow device (13) is composed of a backflow pipe (14), an ultraviolet lamp (16), an aeration disc (17), a mud collecting trough (18), a mud discharging valve (19) and a flow lifting pipe (20). The first pond (1), the second pond (3) and the third pond (5) are of a whole structure, the bottom of the whole structure is inclined from the initial end of the first pond (1) to the tail end of the third pond (5), and the slant slope is 4%. The spiral zero-discharge litopenaeus-vannamei breeding system has the advantages that high-density pond separating breeding of litopenaeus vannamei in different breeding stages is achieved, and breeding management is facilitated; water purifying capacity is high; the structure is compact, and occupied land is saved.

Description

technical field [0001] The patent of the invention belongs to the technical field of aquaculture and water environment protection, and specifically relates to industrialized circulating aquaculture of Penaeus vannamei, and is especially suitable for industrialized aquaculture of Penaeus vannamei in high-density circulating water in inland areas. Background technique [0002] Penaeus vannamei has delicious meat, high processed meat, and wide temperature range. It can grow at 18-32°C and at a salinity of 1-40‰. It is an excellent desalinated cultured species. Penaeus vannamei grows fast and has strong disease resistance. It has gradually become the main cultured shrimp species in my country. [0003] However, with the expansion of Penaeus vannamei aquaculture scale and the improvement of aquaculture density, problems such as environmental pollution and economic constraints are becoming more and more serious, which greatly restricts the development of aquaculture industry.
