[0026] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0027] The following description, with reference to the accompanying drawings, outlines the terminology of the ecological floating island 100 and the wastewater purification system according to this application.

[0028] like Figure 1 and Figure 2 As shown, a specific embodiment of this application provides an ecological floating island 100, including a floating bed 1, an aquatic planting unit, and physical purification equipment. The floating bed 1 is made of buoyancy material and is arranged in the polluted water body. Several equipment installation areas and several planting unit installation areas are formed on the floating bed 1. The aquatic planting units are installed in the planting unit installation areas. The physical purification equipment is installed in the equipment installation areas.

[0029] Polluted water bodies have a significant impact on the environment, and there are many methods for treating them, the most common being physical, chemical, and biological methods. Chemical methods involve adding additives to polluted water to convert dissolved pollutants into insoluble solids that settle in the bottom sediment. While chemical methods are highly efficient, they may cause secondary pollution. In this application, the purification of polluted water using aquatic planting units is a biological method, while the purification of polluted water using physical purification equipment is a physical method. A floating bed 1, suspended on the surface of the polluted water, serves as the carrier for both the aquatic planting units and the physical purification equipment, thus combining multiple treatment methods to purify the polluted water and improve the overall water quality.

[0030] Polluted water bodies contain a large number of pollutants. Biological purification methods focus on building the natural water purification capacity of polluted water bodies by constructing aquatic ecosystems to decompose pollutants and thus purify the water. Pollutants in polluted water bodies reduce the oxygen content. Physical purification methods focus on increasing the oxygen content of polluted water bodies by restoring dissolved oxygen at the bottom of the water to decompose iron, hydrogen sulfide, or ammonia nitrogen in pollutants and thus purify the water.

[0031] Biological purification methods include two types: those using aquatic plants and those using biofilms. Aquatic plant purification utilizes the root system of aquatic plants to absorb pollutants in polluted water, and suitable varieties of aquatic plants can be selected according to the type of polluted water to achieve purification of polluted water under different water quality conditions. Biofilm purification utilizes the metabolic action of microorganisms to degrade pollutants in water, and suitable types of microorganisms can be selected according to the type of pollutant to achieve purification of different pollutants in polluted water.

[0032] It is evident that this application not only combines multiple purification methods to improve water purification, but also avoids causing secondary pollution to polluted water bodies, thereby enhancing the ecological purification effect of the ecological floating island 100 of this application.

[0033] Furthermore, physical purification methods can increase the oxygen content in polluted water, while aquatic plants 4 and microorganisms that carry out biological purification need dissolved oxygen for growth, development, and decomposition of pollutants. Therefore, the combination of physical and biological purification methods in this application can improve the decomposition effect of aquatic plants 4 and microorganisms on pollutants, thereby further improving the water purification effect of the ecological floating island 100.

[0034] In some embodiments, the planting unit installation area is a first mounting hole 2 that penetrates the floating bed 1, and the aquatic planting unit includes a plant planting pot 3, which is engaged with the hole wall of the first mounting hole 2.

[0035] Specifically, the plant planting pot 3 contains a plant growth substrate, and the aquatic plant 4 is planted in the plant growth substrate, which is conducive to the growth and development of the aquatic plant 4.

[0036] Furthermore, the plant planting pot 3 has multiple small-aperture mesh holes, which allow polluted water to pass through the small-aperture structure and the root system of the aquatic plant 4, thereby facilitating the decomposition of pollutants in the polluted water by the aquatic plant 4 and improving the water purification effect of the water purification device.

[0037] Those skilled in the art will understand that the snap-fit ​​between the plant pot 3 and the wall of the first mounting hole 2 can be achieved by having an annular protrusion on the wall of the first mounting hole 2, forming a snap-fit ​​groove with the wall of the first mounting hole 2, and snapping the pot opening of the plant pot 3 into the snap-fit ​​groove. Alternatively, an annular groove can be formed on the top of the first mounting hole 2, and snapping the pot opening of the plant pot 3 into the snap-fit ​​groove. In addition to the snap-fit, other connection methods that can fix the plant pot 3 to the floating bed 1 can also be used, and all of these fall within the scope of protection of this application.

[0038] Furthermore, the plant planting pot 3 and the hole wall of the first mounting hole 2 are used to achieve a detachable connection between the plant planting pot 3 and the floating bed 1, thereby facilitating the harvesting and replacement of aquatic plants 4 in the plant planting pot 3.

[0039] In some embodiments, a rope-like carrier 8 is suspended on the floating bed 1, and multiple biofilm carriers 9 are installed on the rope-like carrier 8. The multiple biofilm carriers 9 are arranged at intervals along the length of the rope-like carrier 8. The rope-like carrier 8 enters the polluted water body under the action of gravity, so that all the biofilm carriers 9 can unfold in the polluted water body.

[0040] Specifically, the biofilm carrier 9 is made of high-density polyethylene material. Microorganisms for biological purification are attached to the biofilm carrier 9. The rope-shaped carrier 8 carries the biofilm carrier 9 into the polluted water body, so that the microorganisms on the biofilm carrier 9 can directly contact the pollutants in the polluted water body, thereby improving the water purification effect of the water purification device.

[0041] Furthermore, a longer rope-like carrier 8 is used to increase the area of ​​the biofilm carrier 9, so as to provide a larger attachment area for microorganisms, so that a large number of microorganisms can be attached to the biofilm carrier 9, thereby increasing the number of microorganisms and improving the water purification effect of the water purification device.

[0042] Preferably, the end of the rope-like carrier 8 is fixed to the wall of the first mounting hole 2 so as to integrate the aquatic plant 4 unit and the rope-like carrier 8 in the first mounting hole 2.

[0043] Furthermore, there are multiple rope-shaped carriers 8, which are arranged at intervals along the circumference of the first mounting hole 2 to increase the number of biofilm carriers 9, thereby increasing the number of microorganisms and improving the water purification effect of the water purification device.

[0044] In some embodiments, the physical purification device includes an air pump, a longitudinal aeration pipe 6 and a transverse aeration pipe 7, with the air pump and the transverse aeration pipe 7 respectively connected to both ends of the longitudinal aeration pipe 6, and the transverse aeration pipe 7 having multiple aeration holes.

[0045] Specifically, the equipment installation area is the second mounting hole 5 that penetrates the floating bed 1. The longitudinal aeration pipe 6 passes through the second mounting hole 5, and the transverse aeration pipe 7 is located in the polluted water body. The air pump introduces air into the longitudinal aeration pipe 6 and the transverse aeration pipe 7. The air enters the polluted water body through the aeration holes on the transverse aeration pipe 7 to increase the dissolved oxygen content in the polluted water body.

[0046] Furthermore, the air pump aerates the water regularly every day to continuously increase the oxygen content in the polluted water, which is beneficial to the growth and development of aquatic plants and the decomposition of pollutants by microorganisms, thereby improving the water purification effect of the water purification device.

[0047] Preferably, the center of the equipment installation area is located at the center of the floating bed 1, and there are multiple planting unit installation areas, which are arranged symmetrically at the center. The center of symmetry of the multiple planting unit installation areas is the center of the floating bed 1, thereby improving the aesthetics of the ecological floating island 100.

[0048] In some embodiments, the outer periphery of the floating bed 1 is provided with a connecting structure, and multiple floating beds 1 are connected by the connecting structure, thereby increasing the size of the ecological floating island 100, thereby covering a larger area of ​​polluted water, and improving the ability to resist wind load, thus preventing the ecological floating island 100 from floating randomly in the polluted water.

[0049] Preferably, the connection structure is an anchor bolt hole 10, through which adjacent anchor bolts are used to connect adjacent floating beds 1.

[0050] Those skilled in the art will understand that the connection structure can also be other types such as snap-fit ​​or bolt connection, and all of these fall within the protection scope of this application.

[0051] In the exemplary embodiment of this application, the floating bed 1 has a square structure, the center of the second mounting hole 5 is located at the center of the square structure, there are four first mounting holes 2 and the line connecting the centers of the four first mounting holes 2 forms a square, there are four anchor bolt holes 10 and the four anchor bolt holes 10 are located at the four corners of the square structure. The buoyancy material of the floating bed 1 is made of high-density polyethylene board, the rope carrier 8 is made of steel wire rope, the plant planting pot 3 is also made of high-density polyethylene material, and the biofilm carrier 9 is made of plastic fiber.

[0052] A specific embodiment of this application also provides a wastewater purification system, including multiple ecological floating islands 100. The multiple ecological floating islands 100, connected as one unit, can cover a large area of ​​polluted water and have good wind resistance. Since the wastewater purification system employs all embodiments of the ecological floating islands 100, it possesses all the beneficial effects brought by the ecological floating islands 100.
