[0038] In order to make the technical solutions and advantages of the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, and are not an exhaustive list of all the embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other unless they conflict.

[0039] Combine Figure 6 and Figure 7 As shown, in one or more embodiments, the present application provides a water body restoration system for an ecological channel 100, which includes: an ecological floating bed 201 and a water level regulating device 202; the ecological floating bed 201 is used to be set in the ecological channel 100, and the ecological floating bed 201 includes a floating support and a growth matrix (not shown), and the growth matrix is set on the floating support; the water level regulating device 202 is used to regulate the water level of the water body in the ecological channel 100.

[0040] The present application provides a water body restoration system for an ecological channel 100. The water level regulating device 202 can adjust the water level of the water body in the ecological channel 100 as needed to reduce the discharge of harmful water bodies; and the ecological floating bed 201 can be used to biodegrade harmful substances in the water body in the ecological channel 100, which is beneficial to the restoration of the water body. When the water body is restored to a certain extent, the water level regulating device 202 is used to discharge water that meets the requirements, which is beneficial to the protection of the water environment.

[0041] In some embodiments, the ecological channel 100 can be an agricultural ecological channel; the ecological floating bed 201 also includes aquatic plants (not shown), which are arranged on a growth substrate. The growth substrate can provide a fixation for the aquatic plants and a certain water purification capacity, thereby facilitating the growth of the aquatic plants on the ecological floating bed 201. The ecological floating bed 201 can have a mesh, and the growth substrate can be supported by the mesh so that the growth substrate is concentrated on the ecological floating bed 201.

[0042] In some embodiments, the aquatic plants include at least one of reed, cattail, calamus, wild rice stem, water plantain, canna, loosestrife and water hyacinth, which is conducive to the restoration of water bodies. Exemplarily, the aquatic plants include reed, cattail, calamus, wild rice stem, water plantain, canna, loosestrife and water hyacinth; or, the aquatic plants include canna, loosestrife, cattail and water hyacinth. Canna and loosestrife have well-developed root systems and can effectively absorb pollutants such as nitrogen and phosphorus; cattail has strong adaptability and can improve the oxygen content of water bodies; water hyacinth can absorb heavy metals and float on the water surface, increasing the greening effect. Or, the aquatic plants include reed, water plantain, cattail and calamus. Reed and water plantain can stabilize the water bank and prevent soil erosion; cattail and calamus have well-developed root systems and can absorb pollutants in the water body, which helps restore water quality. Or the aquatic plants include: canna, loosestrife and cattail.

[0043] Of course, other forms of aquatic plants can also be used, and this application does not specifically limit this. The ecological floating bed 201 is mainly used to eliminate or reduce agricultural pollutant residues such as pesticides, fungicides, herbicides and biopromoters in the water of the farmland ecological channel 100.

[0044] In some embodiments, the growth matrix includes at least one of zeolite, volcanic rock, slag, and perlite. Exemplarily, the growth matrix includes zeolite, volcanic rock, slag, and perlite; when the aquatic plants include canna, loosestrife, cattail, and water hyacinth, the growth matrix may include zeolite and volcanic rock. Zeolite has a strong ion exchange capacity and can absorb pollutants such as ammonia nitrogen and phosphorus in the water body; volcanic rock has many pores, which is conducive to the attachment of microorganisms and enhances the self-purification ability of the water body. When the aquatic plants include reeds, water plantains, cattails, and calamus, the growth matrix includes volcanic rock and slag; volcanic rock can increase the permeability of the matrix, promote the development of plant roots, and facilitate the reproduction of beneficial microorganisms; while slag has strong stability and can provide long-term support. It can also absorb heavy metals and reduce water pollution.

[0045] In some embodiments, the ecological floating bed 201 further includes biological agents, which are disposed in the growth matrix.

[0046] For example, the biological agent in this application, also referred to as an enhancer, is the AM fungus Glomus mosseae HDSF1, deposited with the China General Microbiological Culture Collection Center under the accession number CGMCC No. 3012. The AM fungus Glomus mosseae HDSF1 is a specific strain of AM fungi (i.e., arbuscular mycorrhizal fungi), officially deposited with the China General Microbiological Culture Collection Center under the accession number CGMCC No. 3012. This fungus can coexist with plant roots, improving the plant's ability to absorb nutrients (particularly phosphorus) while also enhancing its resistance to stresses, such as pollution and disease. When aquatic plants establish a symbiotic relationship with Glomus mosseae HDSF1, the biomass of the aquatic plant roots can be increased by 21.3%-34.6%, and the efficiency of removing agricultural pollutants from water bodies can be increased by 11.7%-24.5%. It should be noted that the biological agents used in this application are not limited to the AM fungus Glomus mosseae HDSF1, and other types of biological agents, such as nitrifying bacteria, denitrifying bacteria, or photosynthetic bacteria, can also be used.

[0047] Combine Figures 1 to 3 As shown, in some embodiments, the floating support includes a support net 203 and a floating member 204. The floating member 204 is arranged circumferentially around the support net 203 and has a hook 205. Multiple ecological floating beds 201 are connected to each other. The hook 205 of one adjacent ecological floating bed 201 is hooked to the hook 205 of the other. This allows the support net 203 to provide a support environment for the growth medium and aquatic plants, while the floating member 204 allows for the connection of multiple ecological floating beds 201. For example, the support net 203 is quadrilateral, with a floating member 204 located on each of its four sides. The support net 203 can be made of resin or plastic, which has a lower density than water, making it easier to float on the water. The floating member 204 and the support net 203 can be formed integrally or connected by ropes. The floating member 204 is made of resin or plastic, which has a lower density than water. The floating member 204 can have a hollow structure to increase buoyancy. The solid portion of the support net 203 can also have a hollow structure to further increase buoyancy. The plastic can be polyethylene, polypropylene, polyurethane foam, or ethylene-vinyl acetate copolymer.

[0048] Combine Figure 6 and Figure 7 As shown, in some embodiments, the water level regulating device 202 includes a water level sensor 206 and a drainage regulating device. The water level sensor 206 is used to detect the water level in the eco-channel 100. The drainage regulating device includes a pipe base 207 and a lifting pipe 208. The pipe base 207 is connected to the drainage outlet 101 of the eco-channel 100, and the lifting pipe 208 is connected to the pipe base 207. The lifting pipe 208 is configured to be raised and lowered to adjust the height of the water inlet of the lifting pipe 208. The water level regulating device 202 can also adjust the contact time between the eco-floating bed 201 and the polluted water based on seasonal precipitation levels, water pollutant concentrations, and other factors, thereby ensuring the remediation effect of the eco-floating bed 201 on the polluted water. Exemplarily, the lifting pipe 208 can be a flexible hose or a corrugated tube. The lifting pipe 208 has a certain length redundancy. For example, the lifting pipe 208 is longer than the eco-channel 100 to facilitate raising or lowering the water inlet of the lifting pipe 208. Water level sensor 206 can be mounted on pipe base 207, allowing it to monitor the water level in eco-channel 100. During high-water seasons, when water level sensor 206 detects that the water level in eco-channel 100 is above a set height, the water inlet of lift pipe 208 is lowered to a predetermined position below the set height. This allows water above the water inlet of lift pipe 208 to be discharged outside eco-channel 100 through the water inlet of lift pipe 208, pipe base 207, and drain outlet 101, thereby lowering the water level in eco-channel 100. When field application is not in progress or during dry seasons, lowering the water inlet of lift pipe 208 allows for rapid drainage of water from eco-channel 100.

[0049] Combine Figure 6 and Figure 7 As shown, in some embodiments, the water level regulating device 202 further includes a lifting device 209, which is used to control the raising and lowering of the water inlet of the lifting pipe 208. For example, the lifting device 209 can be a hydraulic cylinder, an electric cylinder, or a pulley mechanism; the lifting device 209 can be installed at the edge of the ecological channel 100 to facilitate support of the lifting device 209.

[0050] In some embodiments, the water level regulating device 202 may further include a controller connected to the water level sensor 206. The lifting device 209 is electrically connected to the water level sensor 206. The water level sensor 206 transmits detected water level information to the controller, which is then used to control the height of the water inlet of the lifting pipe 208 based on the water level information. For example, during a flood season, the water level sensor 206 transmits water level information to the controller. When the controller determines that the water level is greater than a set height, the controller controls the lifting device 209 to lower the water inlet of the lifting pipe 208 to a predetermined height below the set height. This allows water above the water inlet of the lifting pipe 208 to be discharged outside the eco-channel 100 through the water inlet of the lifting pipe 208, the pipe base 207, and the drain 101. Furthermore, when field application is not in progress or during dry seasons, the controller can control the lifting device 209 to lower the water inlet of the lifting pipe 208 to a predetermined height, allowing the water in the eco-channel 100 to be quickly discharged. It should be noted that no matter whether the ecological channel 100 discharges water to the outside or not, water at a certain water level will remain in the ecological channel 100 , which can ensure the survival of aquatic plants on the ecological floating bed 201 .

[0051] In some embodiments, the water level regulating device 202 may further include a sensor switch, which is electrically connected to the water level sensor 206, and the sensor switch is electrically connected to the controller, so that the on / off connection between the water level sensor 206 and the controller can be controlled by the sensor switch. In this way, when it is necessary to disconnect the connection between the water level sensor 206 and the controller, the sensor switch can be used to turn it off; of course, at this time, the controller can still control the lifting device 209 to raise and lower the height of the water inlet of the lifting pipe 208. It should be noted that the flood season and the spraying season do not overlap; during the spraying period or the application of fertilizers, the amount of agricultural pollutant residues in the water body increases. Therefore, by making the water inlet of the lifting pipe 208 higher than the water surface in the ecological channel 100, the water body can be retained in the ecological channel 100 for a longer time, thereby extending the root absorption, root adsorption, water body microbial degradation and plant root allelopathic effect of pollutants by aquatic plants in the ecological floating island, thereby realizing the absorption and adsorption of pollutants by the ecological floating bed 201. When it is detected that the water quality of the water body meets the requirements, the lifting device 209 is controlled by the controller to lower the position of the water inlet of the lifting pipe 208 below the water surface to achieve the purpose of drainage.

[0052] Combine Figure 4 and Figure 5As shown, in some embodiments, the water level regulating device 202 further includes a sampling bucket 210, which is detachably mounted on the water inlet of the lifting pipe 208; the sampling bucket 210 includes a barrel body 211 and a drain cover 212, the barrel bottom of the barrel body 211 is provided with a water outlet 213, the drain cover 212 is movably connected to the barrel body 211, and the drain cover 212 is used to control the opening or closing of the water outlet 213. In this way, the sampling bucket 210 is used to facilitate sampling of the water body, and the sampled water is sent to the monitoring and testing center for water sample analysis to detect whether the water quality of the water body meets the discharge requirements. Exemplarily, the water inlet of the lifting pipe 208 has a circular ring structure, which can make the water inlet circular for easy drainage. The barrel body 211 of the sampling barrel 210 is truncated cone-shaped; the sampling barrel 210 is placed in a circular ring structure, and the maximum diameter of the barrel body 211 is larger than the inner diameter of the circular ring structure. This allows the sampling barrel 210 to serve as a water inlet plug, thus preventing water from being discharged from the ecological channel 100 when the water is not draining. The drain cover 212 is hingedly connected to the bottom of the barrel body 211. The bottom of the barrel body 211 can have a water outlet 213. The area of the drain cover 212 is larger than the area of the water outlet 213. The water outlet 213 can be provided with a sealing ring around the circumference. In this way, when the drain cover 212 is placed on the water outlet 213, a seal can be achieved. A torsion spring can also be provided between the drain cover 212 and the barrel body 211 to achieve automatic closing of the drain cover 212. Drain cover 212 may have a pull cord 214. When drainage is required, pull cord 214 can be used to open drain cover 212, thereby connecting water outlet 213 to lift pipe 208 for drainage. It should be noted that in some other possible embodiments, the water inlet of lift pipe 208 may be replaced with an electric valve 215 to automatically open and close the water inlet. For water sampling, a water bottle or sampling bucket 210 may be used.

[0053] See also Figure 8 As shown, in some other embodiments, the water level regulating device 202 includes a water level sensor 206 and an electric valve 215. The electric valve 215 is disposed at the drain outlet 101 of the eco-channel 100. The water level sensor 206 is used to detect the water level in the eco-channel 100. Exemplarily, the water level regulating device 202 also includes a pipe base 207, which is connected to the drain outlet 101 of the eco-channel 100. The electric valve 215 is mounted on the pipe base 207. The water level sensor 206 is also mounted on the pipe base 207. In this way, the electric valve 215 is used to realize water storage and drainage in the eco-channel 100.

[0054] It should be noted that, see Figure 9As shown, multiple different ecological channels 100 can be connected in series, with a height difference between two adjacent ecological channels. Each ecological channel 100 is provided with a water body restoration system, so that multi-level water body purification can be achieved.

[0055] In a comparative example, the aquatic plants include: canna, loosestrife and cattail. The water in the eco-channel 100 includes herbicides, insecticides and fungicides.

[0056] In one experimental example, the aquatic plants include canna, loosestrife, and cattail; the ecological floating bed 201 includes a biological agent, which is the AM fungus Glomus mosseae HDSF1; and the water in the ecological channel 100 includes herbicides, insecticides, and fungicides.

[0057] exist Figure 10 In the figure, the white columns represent the growth of plants in the control example when no enhancer was applied. The gray columns represent the growth of plants in the experimental example when the enhancer was applied. Figure 10 It can be seen that the plant height of all plants after application of the enhancer was significantly higher than that of the control group, indicating that the enhancer significantly promoted plant growth (P < 0.05), where the P value is an indicator used in statistics to test the significance of the hypothesis.

[0058] exist Figure 11 In the figure, the blank white columns represent the elimination efficiency of different chemicals in the control group without the application of the enhancer, and the gray columns represent the elimination efficiency of different chemicals in the control group with the application of the enhancer. According to Figure 11, compared with the control group, the application of the enhancer significantly increased the elimination efficiency of farmland pollutants in water bodies (P < 0.05).
