detailed description

The content of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments of the description:

Embodiment one:

As shown in Figures 2 and 3: a culture pond of a shrimp culture system, it and the sewage purification mechanism in the shrimp culture system are interconnected to form a circulation system through pipelines, wherein the culture pond 1 is connected with the sewage purification mechanism The pipeline is provided with a water pump, and it is characterized in that: the bottom of the culture pond 1 is provided with a main sewage channel 10 distributed horizontally, one end of the main sewage channel 10 extends to the left side wall of the culture pond 1, and the other end of the main sewage channel 10 One end passes through the opening that is provided with on the right side pool wall of culture pond 1 and connects the sewage pipe, and the bottom of described culture pond 1 is also provided with several sub-sewage passages 11 that are vertically distributed, and one end of the sub-sewage passage 11 is connected with the main sewage passage. The sewage channel 10 is connected, and the other end of the sub-sewer channel 11 extends to the side wall of the culture pond 1. The sub-sewer channel 11 is provided with several passages for sewage to flow in and the size is moderate. The bottom of the culture pond 1 is wavy and Sub-sewage channels 11 are arranged at the trough.

The size of the through hole provided on the sub-sewage channel 11 must be moderate. On the one hand, it is necessary to ensure that the sewage can flow into the sub-sewage channel 11 in a timely and smooth manner, and on the other hand, it must be ensured that the shrimp will not flow into the sub-sewage channel 11 with the sewage. .

Because the sub-sewage channels 11 arranged vertically can be densely spread over the bottom of the whole culture pond 1, so that the sewage outlet at the bottom of the culture pond 1 is expanded relative to the traditional culture pond sewage outlet, so that the sewage in the culture pond 1 can be effectively , Timely discharge can better maintain the water quality in the culture pond 1, so the culture pond 1 with this structure has a better sewage discharge effect than the traditional culture pond 1.

The main sewage channel 10 is coincident with the median line at the bottom of the culture pond 1 . Such a design can make the sub-drainage channels 11 evenly distributed, thereby making the through holes evenly distributed.

The sub-sewerage channel 11 is a sub-sewerage pipe, and several through holes 12 are provided on the sub-sewerage pipe.

As shown in Figure 6: the sewage purification mechanism includes a filter sand tank 2, an ultraviolet sterilizer 3, a protein separator 4 and a biochemical filter 5, and the filter sand tank 2, an ultraviolet sterilizer 3, and a protein separator 4 And the biochemical filter 5 communicates with each other in turn through pipelines, and the biochemical filter is connected with the culture pond 1 in the shrimp farming system through a return pipe.

The protein separator of the filtration system of the present invention can not only remove ammonia nitrogen in water, but also increase dissolved oxygen in water. For feeding in circulating water, adding dissolved oxygen is very beneficial for high-density feeding. The protein separator fully mixes air and water, and generates a large number of microbubbles in the water. Due to the surface tension and electrostatic adsorption of the microbubble gas-liquid interface, the organic matter in the water (fish, shrimp, shellfish excrement and food residues, etc.) ) is separated from the adhesion and support in the water to avoid its decomposition into toxic substances, so as to achieve the purpose of purifying water quality. The biochemical filter of the present invention can use biochemical action to remove residual organic substances in water and further purify water. In summary, the present invention integrates the filter sand tank, ultraviolet sterilizer, protein separator and biochemical filter, which can not only fully filter and remove harmful substances such as shrimp residual bait and feces, but also sterilize and remove harmful substances such as ammonia nitrogen. substances, so that the sewage produced in the culture pond 1 is purified more cleanly and completely, thereby ensuring the good water quality requirements of shrimp culture.

Embodiment two:

Embodiment 2 of the present invention is similar to Embodiment 1 in general structure, and its main difference is that the structure of sub-sewage channel 11 is different, as shown in Figures 4 and 5: the sub-sewage channel 11 described in Embodiment 2 is a sub-sewage tank , the notch of the sub-drainage tank is upward, and the notch upper cover of the sub-drainage tank is provided with a grille plate 13. The holes on the grid plate are equivalent to the through holes for the sewage to flow into the pipe.
