[0002] Aquaculture tail water refers to wastewater generated during aquaculture, which contains a large amount of organic matter, nitrogen, phosphorus and other nutrients. If it is discharged directly, it will pollute the surrounding water environment. Aquaculture tail water recycling refers to the treatment of aquaculture tail water by physical, chemical and biological methods to remove harmful substances and realize the recycling of water resources. This process usually includes steps such as solid-liquid separation, biological treatment, and nutrient removal. Through recycling, not only the direct discharge of aquaculture tail water is reduced, environmental pollution is reduced, but also the recycling rate of aquaculture water can be improved, saving water resources. At the same time, the recycled nutrients can be used for agricultural fertilization, realizing the effective circulation of resources and the maintenance of ecological balance, which is one of the key measures for the sustainable development of modern aquaculture.

[0003] However, the automation level of aquaculture tailwater treatment equipment in the prior art is low, relying on manual operation and low efficiency.
