Problems solved by technology

The traditional recirculating aquaculture system is suitable for fish farming but difficult for prawn farming due to the differences in the breeding process caused by the differences in the breeding objects. Applying the recirculating aquaculture system to the culture process of Penaeus vannamei, At the same time, it is combined with the biofloc culture mode, and the biofloc pool is replaced by the biofilter. More importantly, the biofloc water treatment process is isolated from the living environment of the shrimp, and other facilities are designed to be modified accordingly, which can be established. Shrimp circulating aquaculture model based on biofloc water treatment technology

Embodiment 1

[0044] Such as Figure 1-3 As shown, a circulating water Penaeus vannamei culture system based on biofloc water treatment technology includes a culture area and an external treatment area; wherein,

[0045] The breeding area includes a breeding pond 1 and a mixed water pond 2; the breeding pond is used for cultivating prawns, and the bottom is provided with a breeding pond drain 11, and the drain is provided with a pull-out switch, that is, a 90-degree elbow is arranged on the drainage pipe, and the elbow The mouth is vertically upward, and a PVC pipe higher than the culture liquid level is inserted into it. At this time, due to the water pressure, the liquid level in the vertically inserted PVC pipe is consistent with the liquid level in the culture pond. Once pulled out PVC pipe, the breeding pond starts to drain, and it can stop draining when it is plugged in again. Preferably, a solenoid valve can be installed, and the drainage behavior can be controlled electrically or au...

Embodiment 2

[0054] Such as Figure 4 As shown, the external treatment area also includes a water distribution tank 10, which is connected to the other side wall of the physical filter tank 6, and the side wall is provided with an overflow port; the bottom end of the water distribution tank is a water outlet 65 of the physical filter tank, which is connected with Breeding area inlet main pipe 8 links to each other. The water distribution pool is located at the end of the water treatment area. A small pool can be isolated at the end of the water treatment pool where the filter screen is located as the water distribution pool. The water distribution pool and the filter screen can be separated by a partition or a solid wall. An overflow port is opened on the top of the plate or solid wall, and the water filtered by the filter screen overflows into the distribution pool, and the bottom of the distribution pool is opened with a water outlet, and the water in the high-level distribution pool pas...

Abstract

The invention relates to the technical field of aquaculture, in particular to a litopenaeus vannamei recirculating aquaculture system based on a biological floccule water treatment technology. The system comprises a culture area and an external treatment area, wherein the culture area comprises a culture pond and a water mixing pond, and the external treatment area comprises a biological flocculation pond and a physical filtering pond. According to the litopenaeus vannamei recirculating aquaculture system based on the biological floccule water treatment technology, the biological floccule water treatment process is independent from a culture water body, meanwhile, the biological flocculent water treatment technology and a circulating water treatment method are combined in technology and facility engineering, so that the daily maintenance management of the biological floccules is facilitated, and the whole system has the advantages of being convenient to manage, capable of saving energy, reducing the culture risk and improving the culture efficiency.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a circulating water culture system for Penaeus vannamei based on biofloc water treatment technology. Background technique [0002] Biofloc refers to the inorganic and organic matter mainly composed of aerobic microorganisms in aquaculture water, including bacteria, phytoplankton, algae, organic debris (residual bait, feces), and some inorganic debris through bioflocculation. Agglomerates. The nutrient structure of the water body can be adjusted by using biofloc technology; organic carbon can be added to the water body to adjust the carbon-to-nitrogen ratio in the water body to promote the reproduction of heterotrophic bacteria in the water body, and then use microorganisms to decompose inorganic nitrogen to metabolize and decompose shrimp in the aquaculture water body. The nitrite nitrogen and ammonia nitrogen produced by the corruption of organic matter are converted into t...
