DETAILED DESCRIPTION

[0024] In order to enable people skilled in the art to better understand the technical solutions in this application, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings and embodiments. Obviously, the described embodiments are only part of the embodiments of this application. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of this application.

[0025] Example 1:

[0026] like Figure 1-5 As shown, an artificial wetland micro-polluted water purification structure is used to treat micro-polluted water and prevent direct discharge of micro-polluted water from polluting the water environment. The structure includes a biological pool 1, an aquatic plant pool 7, an aeration tank 38, and a sedimentation tank 39. The biological pool 1, the aquatic plant pool 7, the aeration tank 38, and the sedimentation tank 39 are connected in sequence. The drainage end of the sedimentation tank 39 is connected to the drainage outlet 28. The biological pool 1 is filled with multiple gabions 2, which are filled with multiple stones and have multiple through-holes. The aeration tank 38 is equipped with an ozone aeration mechanism, which provides ozone aeration to the aeration tank 38. The sedimentation tank 39 is equipped with a water quality detector 22 for monitoring the water quality of the sedimentation tank 39. The drainage outlet 28 is provided with an aquatic plant area 29 for growing aquatic plants. The bottom and side surfaces of the biological pool 1, the aquatic plant pool 7, the aeration tank 38, the sedimentation tank 39, and the drainage outlet 28 are all coated with a waterproof layer 3.

[0027] The biological pool 1 is filled with microorganisms required for degrading slightly polluted water.

[0028] One structure of the gabion 2 is a stainless steel mesh cage. When in use, the stainless steel mesh cage is filled with multiple stones, each of which has multiple honeycomb holes, which not only facilitate the flow of water but also facilitate the accumulation of microorganisms in the honeycomb holes. When water flows through the honeycomb holes, the microorganisms in the honeycomb holes degrade the water.

[0029] Filling the biological pool with multiple gabions can slow down the flow rate of water in the biological pool, which is beneficial to the contact time between microorganisms in the biological pool and the water, thereby facilitating the effective degradation of the water in the biological pool by microorganisms.

[0030] The aquatic plant pool 7 can use a floating frame 37 to plant aquatic plants, which is beneficial for the roots of the aquatic plants to be inserted below the water surface, so that the aquatic plants can achieve a degradation effect on the water body in the aquatic plant pool.

[0031] It should be noted that the aquatic plants that can be planted in the aquatic plant pond and aquatic plant area can be floating plants.

[0032] The floating plant includes any one selected from the group consisting of duckweed, water lettuce, water lily, and water hyacinth.

[0033] The groups consist of:

[0034] Single floating plant: duckweed, water lettuce, water lily or water hyacinth.

[0036] Three types of floating plants: duckweed, water lettuce and water lily; duckweed, water lettuce and water hyacinth; duckweed, water lily and water hyacinth, water lettuce, water lily and water hyacinth.

[0037] Four types of floating plants: duckweed, water lily, water lily and water hyacinth.

[0038] The aquatic plant layer can be any one of the above groups. Duckweed, water hyacinth, water lily, and water hyacinth can absorb heavy metal elements.

[0039] Plants that can be planted in the aquatic plant area of ​​the drain outlet may also include snake grass, red pepper, goose not eating grass and / or field edge chrysanthemum.

[0040] It is understood that the water in the drain outlet 28 can be discharged into the river.

[0043] During use, the ozone generator 9 generates ozone, which is then pumped by the aeration pump 10 to the aeration pipe. The aeration pipe then aerates the ozone into the aeration tank via multiple aerators 15 installed thereon. Ozone can decolorize, sterilize, deodorize, and degrade COD in water.

[0044] In some embodiments of the present disclosure, a structure of an aeration tube is provided. Figure 3 and 4 As shown, the aeration pipe includes an air supply pipe 12, a distribution pipe 13, and a bronchial pipe 14.

[0050] The first drive motor 18 drives the first drive shaft 20 to rotate. The first drive shaft 20 drives the first gate 16 . The first gate 16 rotates via the first rotating shaft 17 .

[0051] When opening, the first drive motor drives the first drive shaft 20 to rotate clockwise, the first drive shaft 20 drives the first gate 16 to rotate clockwise, and the first gate 16 rotates clockwise relative to the first dam mouth, thereby opening the first dam mouth, and the water in the aeration tank 38 flows into the sedimentation tank 39 through the first dam mouth 191.

[0052] When closed, the first drive motor drives the first drive shaft 20 to rotate counterclockwise, the first drive shaft 20 drives the first gate 16 to rotate counterclockwise, and the first gate 16 rotates counterclockwise relative to the first dam mouth 191, so that the first gate is closed at the first dam mouth, blocking the water in the aeration tank 38 from flowing into the sedimentation tank 39 through the first dam mouth 191.

It is understood that the biological pool is higher than the aquatic plant pool, which is higher than the aeration pool, which is higher than the sedimentation pool, which is higher than the drain outlet.

[0073] The water-conducting slope allows water to come into contact with air as it flows down the slope, increasing the dissolved oxygen in the water.

[0074] like Figure 2 As shown, a mitigation plate 8 is provided at the top of the water guide slope 5 between the aquatic plant pool 7 and the aeration tank 38. The mitigation plate 8 has an arc-shaped structure. The center of the arc is located within the aquatic plant pool, which facilitates the backwash of water from the aquatic plant pool to the mitigation plate 8, thereby slowing the water flow and facilitating the absorption and degradation of the water by the aquatic plants.

[0075] The slope of the water diversion slope can be selected as 30°, 40°, 50° or 60°, etc. The appropriate slope can be selected according to needs.

[0076] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
