[0022] Reference Figure 1 , Figure 2 , an aeration and reoxygenation water purification device, comprising an independently arranged aeration device 1 and a purification device 2. The aeration device 1 and the purification device 2 can be used separately or in combination as needed, and the use method is more flexible, saving equipment costs. The aeration device can be a jet aeration device or a mechanical aeration device. The purification device 2 is not limited in shape in this embodiment, and can be rectangular, annular, circular, etc. The purification device 2 is arranged in the aeration area of ​​the aeration device 1. The aeration device 1 increases the oxygen content of the water body by mixing air into the water. The purification device 2 includes a floating body 3, and the floating body 3 is provided with a plurality of planting tubes 4. The planting tube 4 is a cylindrical body with an open end. The open end of the planting tube 4 is exposed to the water surface, and the closed end of the planting tube 4 is submerged in the water. The wall of the planting tube 4 is provided with a plurality of through holes 5. The planting tube 4 is planted with emergent plants, and the roots of the emergent plants grow in the planting tube 4. A plurality of hanging materials 7 are hung below the floating body 3. The hanging material 7 is one or more of biological rope filler, biological ceramsite, plastic filler, biological filter ball and biological felt.

[0023] In the design of this embodiment, the roots of the emergent plants can release oxygen, absorb nutrients in the water, purify the water body, reduce the nutrient concentration of the water body, and thus prevent eutrophication of the water body; and the hanging material 7 can provide a growth carrier for microorganisms in the water, and under the action of the aeration device 1 and the oxygen released by the roots, the formation and activity of microbial communities are promoted, thereby purifying the water quality; at the same time, the bubbles in the aeration area will touch the hanging material 7 during the floating process, and a part of the bubbles will be trapped and attached to the hanging material, which increases the residence time of the bubbles in the water and allows more oxygen to be dissolved in the water.

[0024] The manufacturing cost of this embodiment is low. Through clever design, the purification device 2 is placed in the aeration area, so that the purification device 2 and the aeration device 1 complement each other. The purification device 2 can intercept bubbles, so that more oxygen is dissolved in the water, and at the same time, the flow of nearby water bodies is accelerated, thereby promoting the formation and growth activities of microbial communities; and the growth of emergent plants can effectively degrade various organic substances such as nitrogen, phosphorus, hydrogen sulfide, and phosphite in the water, inhibit the proliferation of bacteria in the water, and reduce the turbidity and odor of the water. Under the joint action of the microbial community and the emergent plants, the water purification efficiency is higher and the effect is better.

[0025] Furthermore, the aeration device 1 includes a floating plate 8 and a plug flow aerator 9, and the plug flow aerator 9 is fixed between two floating plates 8. The plug flow aerator 9 is provided with a water spray port 10, and the water spray port 10 is connected to an air inlet pipe 11, and the air inlet pipe 11 is exposed to the water surface. By using the negative pressure principle, the air in the air inlet pipe 11 is sucked into the water spray port 10, and the air is mixed with the water flow in the water spray port 10 and sprayed, thereby achieving the effects of oxygenation, plug flow, aeration and stirring, so that the water purification effect of this embodiment is better.

[0026] Furthermore, the purification device 2 is arc-shaped, and the concave side of the purification device 2 faces the aeration device 1. In this design of the embodiment, the purification device 2 surrounds the aeration device 1, so that the purification device 2 can make full use of the aeration area.

[0027] Furthermore, the floating plate 8 and the purification device 2 are connected via a fixing member. Specifically, the aeration device 1 and the purification device 2 can be connected via a rope 12 or a bracket.

[0028] Furthermore, the fixing member is a rope 12. The design of this embodiment is not only low in cost, but also the aeration device 1 and the purification device 2 are relatively independent and easy to disassemble and assemble, and when one of them floats, the other is less affected.

[0029] Furthermore, the planting tube 4 is in the shape of an inverted truncated cone. Specifically, the upper end of the planting tube 4 is larger than the lower end. This shape of the present embodiment is more convenient for planting.

[0030] Furthermore, the floating body 3 is provided with a plurality of through holes 13, the shape of the through holes 13 matches the planting tube 4, and the planting tube 4 is sleeved on the top of the through holes 13 through a detachable structure. Specifically, the planting tube 4 can be sleeved, snapped or locked on the top of the through hole 13. With such a design, if a plant in a planting tube 4 grows poorly or dies, the planting tube 4 can be directly replaced or taken out separately for cultivation, which can better take care of the emergent plants.

[0031] Furthermore, the float 3 is made of a composite fiber layer, which includes a polyester fiber layer 14 and a coconut fiber layer 15, and the coconut fiber layer 15 is arranged between two polyester fiber layers 14. The design of this embodiment not only has low material cost, but also has a good trapping effect on aerated bubbles, and the bubbles can be attached to the composite fiber layer.

The floating block 6 is a hollow structure, and an openable sealing cover 17 is arranged on the upper surface of the floating block 6. In this embodiment, the buoyancy of the floating body 6 can be controlled by injecting water into the floating body 6, thereby controlling the sinking depth.

[0033] The above implementation modes cannot limit the protection scope of the present invention. The equivalent modifications and changes made by those skilled in the art without departing from the overall concept of the present invention are still within the scope of the present invention.
