[0003] Therefore, to ensure the long-term sustainable development of the bullfrog industry, the transformation of the bullfrog breeding model needs to be addressed urgently. It is necessary to clarify the water requirements for bullfrog breeding land and the construction standards of breeding farms, approve and issue breeding licenses according to procedures, and supervise the operation of bullfrog breeding farms according to environmental protection and food safety requirements to provide policy guarantees for the healthy development of the industry. The most important point is to innovate the breeding model, do a good job in tail water treatment, and ensure environmental safety. Utility Model Content

[0009] Advantages of the utility model:

[0010] (1) Shelf farming makes full use of three-dimensional space to ensure high yields, uses centralized management, and does not occupy land area.

[0011] (2) The aquaculture tail water is graded and treated, and the organic nitrogen and phosphorus in the aquaculture tail water are effectively utilized after being grown in hydroponic plants, which reduces the rate of new water use and saves water resources.

[0012] (3) This model couples three-dimensional layered culture and multi-level sedimentation systems, and combines aquatic vegetable and fruit gardens to form a closed and benign ecological circulation system, realizing "one water, multiple uses, ecological circulation".

[0015] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] like Figure 1 and Figure 2As shown: A low-carbon green cycle bullfrog breeding system, including an aquatic plant pond, a fruit planting area, a layered bullfrog breeding area, a multi-level sedimentation area and a hydroponic vegetable pipeline connected by pipes. The tail water produced by the aquatic plant pond enters the fruit planting area, the tail water of the fruit planting area enters the layered bullfrog breeding area, and the tail water of the layered bullfrog breeding area enters the aquatic plant pond through the multi-level sedimentation area and the hydroponic vegetable pipeline to form a cycle. The layered bullfrog breeding area adopts a stainless steel or galvanized frame pool, which can be built in 5-6 layers. Each single breeding frame on each layer is 20 meters long, 4 meters wide, and 0.3-0.4 meters deep. An anti-escape silk net can be pulled around the frame. Each breeding frame is laid with an inlet and outlet pipe in the east-west direction, and clean water flows from the water inlet through the breeding frame and then flows out from another drain. Every 50 groups of 6-layer breeding frames are equipped with a primary sedimentation tank, an intermediate sedimentation tank and a secondary sedimentation tank. At the bottom of the breeding pond, the tailwater containing organic particle waste such as residual bait and feces generated during the breeding process is discharged to the multi-level sedimentation area through the sewage pipe. A first-level biological turntable is set between the primary sedimentation tank and the intermediate sedimentation tank, and a second-level biological turntable is set between the intermediate sedimentation tank and the secondary sedimentation tank, which can better treat and decompose the tailwater discharged from the bullfrog breeding area. After passing through the multi-level sedimentation tank, the tailwater is connected to the pipeline hydroponic system. There are two types of hydroponic systems. One is a hydroponic pipeline, which uses a planting trough with a width of 0.8 meters, a depth of 0.6 meters and a length of 30 meters. The trough is filled with light ceramsite to cultivate plants, forming a hydroponic vegetable pipeline. The other is a floor-standing shallow water pool with an area of ​​about 20 mu per well. It can cultivate water spinach and a variety of aquatic plants. After the hydroponic system, tall fruits and fruit economic plants are cultivated. The accumulated fertilizer treated by the sedimentation system can be used in aquatic plant ponds and fruit and vegetable planting areas, thereby achieving a three-dimensional ecological effect of no water change in breeding, pipeline and pond hydroponics, and no additional fertilization of fruit and vegetable crops.
