[0002] The modern factory-based fish-vegetable symbiotic green ecological circular agricultural system is a factory-based agricultural system that integrates biotechnology, engineering technology, and software and hardware system technology, freeing agricultural production from the constraints of natural ecology and producing animal and plant products uninterruptedly throughout the year as planned.

[0003] At present, the factory farming model is gradually replacing the traditional fishery farming model, but the factory farming model still has the problem of eutrophication of water quality. The fish-vegetable symbiotic system can purify the water body through plant absorption, achieve the purpose of waste-free production and increase the income of fishermen. One of the existing fish-vegetable symbiotic models is to separate the aquaculture water body from the planting system. This model can prevent the plant roots from being damaged by fish consumption. It can also be a water circulation process. During this circulation process, the water quality can be further purified and improved as needed. However, the overall solution of the existing fish-vegetable symbiotic system is still immature, and it is not possible to fully recycle various resources. There is a waste of some resources.

[0028] The circulation device 1 comprises a fish pond sewage collection tank 11, a mid-storage sedimentation tank 12, and a clean water circulation tank 13 which are arranged in sequence. The fish pond surface water outflow pipe 8 is connected to the fish pond sewage collection tank 11. The clean water circulation tank 13 is connected to the fish pond 2 through a water pump and a circulating water inlet pipe 14. The circulating water inlet pipe 14 is provided with an ultraviolet disinfection device 15 and a liquid oxygen delivery pipe 16.

[0029] The central sewage pipe 6 of the fish pond is connected to the main sewage pipeline through a water pump, and a physical filtration treatment device is provided. The liquid discharge port of the physical filtration treatment device is connected to the biological transformation tank, and the semi-solid discharge port is connected to the semi-solid residue digestion tank. The water pipes of the multiple planting areas are connected to the fish pond 2 through a water pump.

[0030] The multiple planting areas include the No. 1 pool planting area 17, the No. 2 pool planting area 18, and the No. 3 pool planting area 19. The bottom of the No. 1 pool planting area 17 is paved with 0.6m thick gravel to form a wetland, where celery and water spinach are planted to purify the water. The No. 1 pool planting area 17 is divided into a clear water pool and a water pump space, and the water pump space is used to pump water to the No. 2 pool planting area 18 and the No. 3 pool planting area 19. The No. 2 pool planting area 18 is used for staggered hydroponics and window hydroponics to grow vegetables. The No. 3 pool planting area 19 is used for flat hydroponics and spiral hydroponics to grow vegetables.

[0031] The outlet end of the circulating water inlet pipe 14 is connected to a porous tube 20, the holes of the porous tube 20 are in the same direction, the porous tube 20 is located inside the fish pond 2 and the holes are not aligned with the center of the fish pond 2, so that the water injected into the fish pond 2 can rotate and flow according to its circular characteristics, so that the fish in the fish pond 2 swim against the current, and the liquid oxygen delivery pipe 16 is provided with a liquid oxygen flowmeter 21.

[0032] The upper part of the fish pond 2 is cylindrical and the lower part is conical. The upper opening 5 of the central vertical pipe of the fish pond and the upper end of the water collection port 7 at the edge of the fish pond are both lower than the upper end of the fish pond 2.

[0033] A fish pond rib 22 is disposed outside the fish pond 2, and the fish pond rib 22 is made of a stainless steel square tube.

[0034] The fish pond sewage collection tank 11 is provided with a microfilter and a filler with digestive bacteria attached;

[0035] The water inlet of the intermediate storage sedimentation bin 12 is connected to the water outlet of the fish pond sewage collection bin 11, and a filler of digestive bacteria is attached to the intermediate storage sedimentation bin 12, so as to perform secondary digestion on the untreated secretions;

[0036] The intermediate storage sedimentation tank 12 allows the water in the intermediate storage sedimentation tank 12 to flow naturally to the clean water circulation tank 13 by means of a water level difference, thereby making the water quality of the clean water circulation tank 13 cleaner.

[0037] The fish pond sewage collection tank 11, the intermediate storage sedimentation tank 12, and the clean water circulation tank 13 are all provided with sewage pipes 23 at the bottom, which can regularly discharge the sediment at the bottom of the circulation equipment 13 tanks; the fish pond sewage collection tank 11, the intermediate storage sedimentation tank 12, and the clean water circulation tank 13 are all provided with aerators at the bottom.

[0038] When the present invention is implemented, the earthwork around the greenhouse 24 is first raised to prevent rainwater from entering. The wastewater and leftover bait discharged from the fish pond 2 are the best nutrients for vegetable growth, and the root system and microbial community of vegetables are a natural water purification and filtration system. In this system, water and fish feed are first obtained from the outside and put into the fish pond 2. The fish pond 2 is used for fish farming. The water, leftover bait, and feces in the fish pond 2 are discharged to the physical filtration treatment device through the sewage pipe 6 in the center of the fish pond for treatment. The treated liquid enters the bioconversion tank to convert ammonia and nitrite into nitrate, and the semi-solid residue enters the semi-solid residue digestion tank to liquefy the residue. Energy conversion, biogas generation, and power generation and heating are achieved during the liquefaction process. The treated water is added with organic fertilizers and nutrient solution required by the plants and then enters the planting area for vegetable cultivation. The water can be further purified during the growth of vegetables. The purified water is sterilized by ultraviolet rays and ozone before entering the fish pond 2. In addition, the sewage on the surface of the fish pond 2 enters the circulation device 1 for sewage treatment. The fish pond sewage collection tank 11 is equipped with a microfilter and a filler with digestive bacteria attached to effectively decompose and separate the fish secretions in the first time; the intermediate storage sedimentation tank 12 is attached with a filler with digestive bacteria, so that the untreated secretions are digested twice. The intermediate storage sedimentation tank 12 uses the water level difference to make the water in the intermediate storage sedimentation tank 12 naturally flow to the water purification circulation tank 13, so that the water quality of the water purification circulation tank 13 is cleaner. The purified water is disinfected by ultraviolet disinfection device 15, and after liquid oxygen is transported to the circulating water inlet pipe 14 through liquid oxygen delivery pipe 16, it enters the fish pond 2 together through porous pipe 20. Thus, the sustainability and circulation of fish farming and vegetable planting are realized.

[0039] This system is characterized by high production capacity, high automation and high safety, which can meet the market and consumer demand for healthy, safe and green vegetables and fish. It should be noted that the fish-vegetable symbiotic ecological cycle is mainly the cycle of nitrogen. Different varieties of vegetables require different nutrients. The breeding varieties, breeding density, breeding cycle, etc. have a great impact on nutrients. The ambient temperature and water pH will also have a great impact on microbial transformation. Generally, we design the planting area to be 2-3 times the breeding area. For example, 50kg / m2 of breeding sea bass can be used for 2-3 cubic meters of vegetable planting. No additional fertilizer or nutrient solution is required, nor is it necessary to separately adjust the soil EC. During the operation of the system, the pH of the water will decrease and become weakly acidic. Therefore, in order to ensure normal breeding, baking soda should be added to the circulating water to adjust the pH according to the situation, so that the pH is around 6.0.

[0040] In the description of the embodiments of the present invention, it should be noted that if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings, or the orientation or position relationship in which the invented product is usually placed when used. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0041] In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components must be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0042] In the description of the embodiments of the present invention, "plurality" means at least 2.

[0043] In the description of the embodiments of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
