[0002] Wetlands play important functions in aspects such as water conservation, water purification, flood storage and drought resistance, climate regulation and maintenance of biodiversity. They are important natural ecological systems and also important components of natural ecological space. Traditional physical and chemical restoration technologies have disadvantages such as high costs and negative effects on the environment. Therefore, wetland restoration is mainly carried out through biological restoration technologies at present. For example, a wetland restoration treatment ecological floating island and its working method disclosed in Chinese Patent CN202111634170.1 include 5 floating island monomers and connecting pieces; the ecological floating island combines 5 floating island monomers through connecting pieces and is arranged in a radial shape. After splicing on land, it is assembled and put into the wetland; among them, 1 floating island monomer plants terrestrial plants, and 4 floating island monomers plant submerged plants; the floating island monomer includes a floating island frame that can float on the water surface, a plant planting basket for planting plants and hanging biological membrane fillers, and a treatment water tank for aeration. The wetland restoration treatment ecological floating island and its working method adopt a combined ecological floating island structure, which improves the anti-wave ability and biodiversity.

[0003] When restoring degraded lake wetlands, the wetland environmental system is relatively fragile. Therefore, in order to prevent water flow with pollutants from entering the wetland and avoid damage to the wetland environmental system, it is necessary to fully purify the water flow before discharging it.

The adsorption base layer includes a non-woven fabric cushion layer, a gravel filler layer and a planting soil layer arranged in sequence from bottom to top from the bottom surface of the purification tank;

[0009] The plant layer is arranged on the adsorption base layer.

[0010] As a further description of the above technical solution:

[0011] A water quality sensor is arranged in the sewage storage tank.

[0012] As a further description of the above technical solution:

[0013] The water quality sensor includes one or more of a dissolved oxygen sensor, a conductivity sensor, a turbidity sensor, an ammonia nitrogen sensor, and a PH sensor.

[0019] The sealing assembly includes a baffle and a driving device, the shape of the baffle matches the drain hole, and the driving device is used to drive the baffle to move up and down.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of the present utility model are:

[0021] 1. In the present utility model, the water flow with pollutants is introduced into the sewage storage tank through the water supply main pipe, and flows to the purification tank through the drain holes on the sewage storage tank. The water flow spirally flows downward along the purification tank under the action of gravity. During the downward flow of the water body, the nitrogen and phosphorus in the water body are adsorbed by the functional gravel filler layer, and then the plant roots of the plant layer composed of emergent plants, hygrophytic plants, and grass plants and microorganisms absorb, metabolize, and transform to reduce the pollutants. The pollutants in the water body are reduced and the nitrogen, phosphorus and other pollutants before the water flow enters the degraded lake are reduced through the retention, filtration and adsorption functions of the vegetation.

[0022] 2. In the present utility model, the sewage storage tank can control the opening of different drain holes through the sealing assembly. The water bodies discharged from different drain holes fall on the purification tanks at different heights, so that the distances and times for them to flow to the degraded lake are different, and thus the filtration effects are different. In this way, the sewage storage tank can discharge water bodies with different pollution degrees through different drain holes according to the detected water body pollution situation, thereby controlling different discharge times and purification times of the water bodies into the degraded lake and improving the purification efficiency.

An adsorption base layer is arranged in the purification tank 3, and the adsorption base layer includes a non-woven fabric cushion layer, a gravel filler layer, and a planting soil layer arranged in sequence from the bottom surface of the purification tank 3 from bottom to top;

[0034] The plant layer is arranged on the adsorption base layer.

[0036] The water quality sensor includes one or more of a dissolved oxygen sensor, a conductivity sensor, a turbidity sensor, an ammonia nitrogen sensor, and a PH sensor. The specific selection is flexibly set according to requirements to effectively monitor the pollution condition of the water body in the sewage temporary storage tank 2.

[0037] A plurality of drain holes 21 arranged circumferentially are provided on the side wall of the sewage temporary storage tank 2. A sealing assembly is provided on the side wall of the sewage temporary storage tank 2 at the drain holes 21, and the sealing assembly is used to seal the drain holes 21. The sewage temporary storage tank 2 can control the opening of different drain holes 21 through the sealing assembly. The water bodies discharged from different drain holes 21 fall on the purification tanks 3 at different heights, so that the distances and times for them to flow to the degraded lake are different, and thus the filtration effects are different. In this way, the sewage temporary storage tank 2 can discharge water bodies with different pollution degrees through different drain holes 21 according to the detected water body pollution condition, thereby controlling the different times for the water bodies to be discharged into the degraded lake and different purification times, and improving the purification efficiency.

[0038] Specifically, 4 drain holes 21 arranged circumferentially are provided on the side wall of the sewage temporary storage tank 2.

[0039] The sealing assembly includes a baffle 22 and a driving device 23. The shape of the baffle 22 matches the drain hole 21, and the driving device 23 is used to drive the baffle 22 to move up and down. The driving device 23 drives the baffle 22 to move upward to lift, and the drain hole 21 is opened, and the water body flows out. The driving device 23 drives the baffle 22 to move downward to block the drain hole 21, and the drain hole 21 is closed.

[0040] Working principle: The water flow with pollutants is introduced into the sewage temporary storage tank 2 through the water supply main pipe 9 and flows to the purification tank 3 through the drain holes 21 on the sewage temporary storage tank 2. The water flow spirally flows downward along the purification tank 3 under the action of gravity. During the downward flow of the water body, nitrogen and phosphorus in the water body are adsorbed by the functional gravel filler layer, and then are absorbed, metabolized and transformed by the plant roots and microorganisms of the plant layer composed of emergent plants, hygrophytic plants and grass plants, and the pollutants in the water body are reduced through the functions of vegetation retention, filtration and adsorption, so as to reduce the nitrogen, phosphorus and other pollutants before the water flow enters the degraded lake.
