Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, in particular to an engineering culture system for shrimp ponds. Background Art

[0002] At present, with the development of the aquaculture industry, from earth pond farming to today's factory farming, the entire aquaculture industry has undergone tremendous changes. However, no matter how far the aquaculture industry develops, earth ponds have their irreplaceable advantages. Compared with factory farming, earth ponds are not only cheaper, but also easily accepted by ordinary farmers. At present, the varieties raised in earth ponds still occupy a large market share and are an important part of market supply.

[0003] However, the existing earth pond structure has the following problems:

[0004] 1. The traditional earthen pond aquaculture area varies in size, the water level is shallow, the ponds are diverse in shape, irregular, scattered, not continuous, no sewage discharge, difficult to manage, and poor aquaculture benefits;

[0005] 2. The new type of mulch pond isolates the pond from organic matter and pathogens such as bottom mud, forming an independent breeding system. While reducing shrimp pathogen infection and improving breeding efficiency, it also loses the excellent self-regulation ability of earth ponds. Utility Model Content

[0006] In order to overcome the above-mentioned shortcomings of the prior art, the utility model provides an engineered shrimp pond culture system, which can reduce the contact between pathogenic organisms on the bottom of the pond and shrimp bodies, reduce the frequency of disease outbreaks, and enhance soil pond water quality regulation and culture effects.

[0007] The technical solution adopted by the utility model to solve the technical problem is: an engineering culture system of a shrimp pond, which is characterized by comprising a culture pond, a sewage pump and a blower, wherein the wall of the culture pond is covered with a black film, a nylon screen is laid on the bottom of the pond, a sewage collection pit is arranged in the center of the pond, a sewage pipe and an oxygen pipe are laid in the pond, and the sewage pump and the blower are connected externally respectively.

[0008] As a further improvement of the utility model: the system also includes a first pond, a second pond and a third pond arranged in sequence, the first pond is a primary sedimentation tank connected to the sewage pipe of the breeding pond; the second pond is a biological purification tank, which is slightly lower than the first pond; the third pond is a plant floating bed, which is slightly lower than the second pond.

[0009] As a further improvement of the utility model: the breeding pond has an area of ​​3.0 to 5.0 mu; the pond is 2.5 to 3.0 meters deep, the slope ratio is 3 to 5%, the whole is an inverted three-dimensional trapezoid, and the pond bottom is a pot bottom.

[0010] As a further improvement of the utility model: the diameter of the sewage collection pit is 1.0 to 1.5 meters, and the depth is 0.8 to 1.0 meters.

[0011] As a further improvement of the utility model: the breeding pond is paved with nano air tubes, and the nano air tubes are connected to the oxygen pipeline.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model wraps the aquaculture pond wall with black film and lays nylon screen on the bottom of the pond. The black film creates a dark line environment in the pond (shrimp need a weak light environment), maintains the safety of the pond bank, and prevents the growth of aquatic plants; the nylon screen is used to isolate the bottom of the pond, reduce the contact between the pathogenic organisms on the bottom of the pond and the shrimp body, and reduce the frequency of disease outbreaks.

[0014] 2. The pond is equipped with nano-air pipes and a central sewage collection pit. The nano-air pipes can form microscopic bubbles inside the pipes. The microbubbles float up from the bottom, prompting oxygen to fully dissolve into the water, and the rotation and up and down flow of the water flow can achieve uniform oxygenation of the shrimp pond water. The central sewage collection pit and sewage suction system can enhance the water quality regulation and breeding effect of the earth pond.

[0015] 3. Add a three-stage aquaculture wastewater treatment system, in which the aquaculture wastewater is discharged into the primary sedimentation tank for preliminary sedimentation. After the sewage in the primary sedimentation tank is full, it automatically flows into the biological purification tank. The biological flocs are set up in the pond to purify the wastewater. After the sewage in the biological purification tank is full, it automatically flows into the plant floating bed. By setting up the plant floating bed, harmful substances such as ammonia nitrogen and nitrite in the sewage are absorbed to protect the aquaculture environment and the sustainable development of healthy shrimp farming.

[0016] 4. The breeding pond area is 3.0 to 5.0 acres; the pond depth is 2.5 to 3.0 meters, the slope ratio is 3 to 5%, and the overall shape is an inverted three-dimensional trapezoid. The pond bottom is a pot bottom, which is convenient for management. The supporting oxygenation equipment is economical and cost-effective. At the same time, it is conducive to the dynamic rotation of the pool water, convenient for sewage collection, enhanced water quality regulation, and improved breeding effects.
