Biological culture water tank

Abstract

The invention relates to a biological culture water tank. The biological culture water tank comprises a culture water box and a plurality of biological boxes, a dirt collecting case is fixedly mounted at one end of an inner cavity of the culture water box and comprises a filter tank, a hollow channel is formed in a supporting column, a water pumping pipe is fixedly mounted on the lower surface of the filter tank, and a filter screen is fixedly mounted in the filter tank; the filter screen divides the inner cavity of the filter tank into a water inlet tank and a water outlet tank; a microfilter is mounted above the first biological box; and the last biological box is communicated with the inner cavity of the culture water box. According to the biological culture water tank, the defects in the prior art are overcome, dirt, fish fry, large-particle sinking baits and the like at the bottom of the culture water box enter the filter tank through the water pumping pipe (15), then the fish fry and large-particle sinking baits are blocked in the filter tank through the filter screen, dirt such as excrement penetrates through the filter screen, and flows to the biological boxes through the hollow channel, so that the fish fry or large-particle baits are prevented from flowing out of the hollow channel at the bottom, the water quality is optimized, and the culture space of aquatic organisms is improved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a biological aquaculture tank. Background technique [0002] At present, aquaculture is an important part of agricultural production, and the modern aquaculture industry is becoming more and more intensive. The use of a large amount of feed and its chemicals has brought huge damage to the aquaculture water, and more than half of the aquaculture Relying on the processing capacity of the natural purification ecosystem, a large amount of organic matter cannot be completely decomposed, causing water pollution, which has a greater impact on the survival and growth of aquatic organisms, and even leads to a large number of aquatic organisms dying. [0003] In the prior art, the waste water in the aquaculture tank is usually discharged completely, and then injected into a fresh water body. This treatment method will lead to the discharge of polluted water bodies. Because of the large...

[0002] At present, aquaculture is an important part of agricultural production, and the modern aquaculture industry is becoming more and more intensive. The use of a large amount of feed and chemicals has brought huge damage to the aquaculture water body, and more than half of the aquaculture The processing capacity of the natural purification ecosystem that it relies on will result in a large amount of organic matter that cannot be completely decomposed, resulting in water pollution, a greater impact on the survival and growth of aquatic organisms, and even a large number of deaths of aquatic organisms

[0003] In the prior art, the waste water in the aquaculture tank is usually discharged completely, and then injected into a fresh water body. This treatment method will cause the discharge of polluted water bodies. Large particle bait is washed away by the water flow from the drain at the bottom, so it has greater limitations
