[0030] By applying the technical solution of this embodiment, the ammonia nitrogen value of the water in the breeding pond is detected. When the ammonia nitrogen value of the water in the breeding pond is higher than the predetermined ammonia nitrogen value, the water in the breeding pond is transported to the microbial reactor for sewage treatment. When the ammonia nitrogen value of the water in the microbial reactor meets the requirements, the water in the microbial reactor is transported to the breeding pond. In this way, the survival rate of aquatic products in the breeding pond is higher.

[0051] Beneficial Effects

[0052] 1. The present application sets the bottom of the breeding pond as an inclined plane, and sets a sewage collection tank at the lowest point of the inclined plane. The waste automatically slides down into the sewage collection tank through the inclined plane. A water pump is fixedly installed on the right side of the sewage collection tank, which can draw the water in the sewage collection tank into the circulation pipe, and then discharge it through the drain port to enter the purification box or the airlift microbial reactor. The water passes through the purification box and filters the waste in the water through the filter screen one. The ammonia nitrogen content in the water is reduced through the filter screen one or through the airlift microbial reactor. The water entering the breeding pond realizes the internal circulation of the water flow, reduces the waste content in the water, significantly improves the survival rate of aquatic products, and is easy to use.

[0053] 2. The present application sets up a cleaning structure, in which a pumping device controls floating waste to enter the cleaning pipe. The floating waste flows through the pumping device and flows out from the other side of the cleaning pipe into the purification box 2. The filter net 2 in the purification box 2 filters the floating waste, and the filtered water flows into the breeding pond, which can improve the cleanliness of the water in the breeding pond and reduce the waste content in the water in the breeding pond.

[0054] 3. The present application connects an internal circulation pulse airlift microbial reactor to the circulation pipe. The composite microbial preparation fermented in the device is used to treat nitrogen (N), potassium (K), and phosphorus (P) in the aquaculture pond water, which can effectively reduce the content of NH3-N, NO2-N, and chemical oxygen demand (COD) in the aquaculture water. At the same time, it can also provide nutrients for phytoplankton, which is mainly unicellular algae, and promote its reproduction. The photosynthesis of these phytoplankton provides oxygen for the respiration of benthic aquatic animals and the decomposition of organic matter, thus forming a benign ecological cycle. In addition, the microbial reactor uses pulse air intake to facilitate the reproduction of Bacillus. Due to the large-scale reproduction of Bacillus, a dominant population is formed in the pond, which can inhibit the proliferation of pathogenic microorganisms, thereby purifying the water quality, reducing the occurrence of diseases, and improving the survival rate of aquatic products.

[0055] 4. This application adds an air compression purification system to the air intake pipeline. When the compressed air passes through the filter assembly, it can process impurities such as moisture, oil droplets, and particulate dust in the compressed air to meet the cleanliness requirements and avoid affecting the fermentation process of the microbial reactor. In addition to the air compression purification system, a photovoltaic power generation system is also set up to supply power to the power device to save energy. In addition, an online automatic ammonia nitrogen water quality monitor is set in each of the breeding ponds and microbial reactors, which can detect the ammonia nitrogen value in the water in real time and effectively control the ammonia nitrogen content in the breeding pond.
