Aquaculture pond with vortex sewage discharge performance

The invention relates to an aquaculture pond with vortex sewage discharge performance. The aquaculture pond is characterized by comprising multiple micro ponds arranged to form a shape like a Chinese character 'tian' (field), the aquaculture pond is square, and pond walls are 2.0-2.5 m high. The micro ponds are square rounded-corner ponds with the side length of 16-23 m. The micro ponds have the interval embankment gradient of 30-45 degrees, the height of 1.0-1.5 m and the pond bottom height of 5-15 degrees. An independent sewage drain port is formed in the geometric center of the bottom of each micro pond and downwards connected to an external sewage drain canal of the aquaculture pond. One aerator is mounted in each of opposite corners of each micro pond to provide water vortex power, the total power of the aerators equipped on each micro pond is 1.5-3.0 kW, and the water pushing direction of the aerators meets the conditions that the water flow direction in the micro ponds is opposite to the water flow dir
