Example, refer to fig. 1 to 5.
The embodiment of the invention provides an aeration and oxygenation system,
as shown in fig. 1, the device comprises a gas-water mixing chamber 200, an oxygen concentrator 100, a connecting shaft, an air guide sleeve, a motor 700 and a buoyancy seat 900;

The aeration and oxygenation system can float on the water surface by utilizing the buoyancy of the buoyancy seat 900, and the aeration is ensured to be uniform. The air guide sleeve is used for conveying air on water into the oxygen concentrator 100 and the air-water mixing chamber 200.
The oxygen concentrator 100 is provided with a strong magnetic field, and by utilizing the principle of magnetic conductivity and the difference between oxygen magnetism and nitrogen magnetism in the air, namely paramagnetism of oxygen and diamagnetism of nitrogen, the sewage is magnetized by adopting a high-gradient magnetic field, and the capacity of the magnetized water for dissolving oxygen is greatly enhanced.
The motor 700 drives the connecting shaft to rotate, so that water at the bottom end of the connecting shaft flows at a high speed to form a negative pressure area. Oxygen in the air is fully cut by magnetic lines of force when entering the strong magnetic field of the oxygen concentrator 100 through the air guide sleeve at a high speed under the action of negative pressure of the air-water mixing chamber 200, so that the oxygen-enriched magnetized water becomes more activated, and the affinity with the magnetized water is enhanced after the oxygen-enriched magnetization, so that the capability of dissolving oxygen in sewage can be obviously improved, and good aeration, oxygenation and stirring effects are generated.
In the gas-water mixing chamber 200, the magnetized oxygen and the magnetized water are divided into micro bubbles by the impeller 311 rotating at high speed in the gas-water mixing chamber 200 in the synthesis process, so that the affinity of the water and the air is improved, and the micro bubbles are difficult to float out of the water surface in a short time when the water flow rate is greater than the buoyancy of the bubbles, thereby prolonging the retention time of the micro bubbles in the water, greatly improving the efficiency of dissolved oxygen in the water, and leading the power efficiency of the aerator to be obviously higher than that of the traditional aeration equipment.
