[0042] The working principle of this embodiment is described in detail as follows:

[0043] (1) The excrement produced by the fish and shrimp in the aquaculture tank 11 passes through the filter net and filter cotton on the physical and biological filter tank 13 to form small molecules, and then through the action of biological bacteria, it can decompose NH 3 , Enter the water quality conversion tank 12, form NO after adding nitrifying bacteria 3 , The nutrient solution is provided to the activation tank 23 and output to the plant shelf 21 as nutrients for absorption or flow back into the aquaculture tank 11.

[0044] (2) Excess nutrient solution flows out from the nutrient solution recovery port 212 at the bottom of the planting shelf 21, enters the nutrient solution recovery filter tank 22 for filtration, then enters the nutrient solution activation tank 23, and flows into the nutrient solution preparation tank 24 through the sixth outlet 202 The raw material adding mechanism 40 and the algae culture processing adding device 50 add raw materials and algae to the nutrient solution mixing tank monitoring system 24 according to actual needs to form a new nutrient solution, which flows to the nutrient solution through the eighth outlet 206 The aquaculture tank 11 is used for fish and shrimp and flows back to the nutrient solution activation tank 23 through the seventh outlet 205 to provide nutrient solution required by plants.

[0045] (3) The purified water in the water purification equipment 15 flows into the spare water tank 16, and then enters the water circulation equipment 17, and flows into the breeding tank 11 after passing through the water circulation equipment 17, and the water in the breeding tank 11 can flow back to the water circulation The equipment 17 achieves the effect of purifying water quality, thereby forming a water circulation process in the breeding system 10.

[0046] The design focus of the present invention is that the fish-vegetable symbiosis integration system integrates aquaculture and vegetable production through ecological design, and provides nutrients for vegetables through physical and microbial decomposition of the organic matter in the excrement of the aquaculture tank, saving plant nutrient solution consumption At the same time, the planting system can purify the water used for breeding, and provide the bait needed by fish and shrimp, save the amount of bait used, so as to realize a sustainable and circular zero-emission low-carbon production model, and at the same time increase industrial benefits. And algae can be used as plant nutrient solution and fish and shrimp nutrient, thereby saving the amount of nutrient solution and fish and shrimp bait used, and can purify water quality, achieve ecological balance, and save water resources; the fish and vegetable symbiosis integration system is also set up There are independent oxygenation equipment to achieve high-density and safe breeding.
