DETAILED DESCRIPTION

[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0020] refer to Figure 1-2 , a three-dimensional composite water purification device, comprising:

[0021] A self-rotating aeration module 1 is provided in the middle of a water body, and further comprises: an aeration pipe 11, wherein the aeration pipe 11 further comprises a lower aeration pipe 111, a middle aeration pipe 112 and an upper aeration pipe 113, wherein the upper aeration pipe 113 is connected with the lower aeration pipe 111 through the middle aeration pipe 112, and the aeration nozzles 114 of the aeration pipe 11 are arranged counterclockwise or clockwise; the upper aeration pipe 113 and the lower aeration pipe 111 are both annular, and the middle aeration pipe 112 is linear; an aerator 12, wherein the aerator 12 is connected with the upper aeration pipe 113 through a connecting pipe 13; and the self-rotating aeration module 1 further comprises a solar power generation unit 14, wherein the solar power generation unit 14 is used to supply power to the aerator 12.

[0022] The ecological floating bed module 2 is arranged on the upper aeration pipe 113, and the ecological floating bed module 2 is used to carry emergent plants; the ecological floating bed module 2 also includes a floating bed 21 and a plant planting hole 22, the floating bed 21 is arranged in the middle of the upper aeration pipe 113, and the edge of the floating bed 21 is fixedly connected to the upper aeration pipe 113.

[0023] A biological filter membrane module 3, wherein the biological filter membrane module 3 is arranged on the lower aeration tube 111 and the middle aeration tube 112, and the biological filter membrane module 3 is used to carry the biological filter membrane; the biological filter membrane module 3 also includes a filter membrane support rod 31, a plate-shaped biological filter membrane 32 and a strip-shaped biological filter membrane 33, the filter membrane support rod 31 includes a first filter membrane support rod 311 and a second filter membrane support rod 312, the first filter membrane support rod 311 is arranged on the lower aeration tube 111 along the inner diameter of the lower aeration tube 111, and the second filter membrane support rod 312 is arranged between the two middle aeration tubes 112; the plate-shaped biological filter membrane 32 is arranged between the first filter membrane support rod 311 and the second filter membrane support rod 312; one end of the strip-shaped biological filter membrane 33 is fixedly connected to the lower aeration tube 111.

[0024] The upper aeration pipe 113 is set 10-50cm below the water surface, and the lower aeration pipe 111 is set 50-100cm above the riverbed. Emergent plants are planted in the plant planting holes 22 to absorb nutrients in the water body, thereby achieving a partial water purification effect, while the plate-shaped biofilter membrane 32 and the strip-shaped biofilter membrane 33 give full play to the adsorption and absorption effect of the microorganisms carried by the biofilter membrane to purify the deep water body. At the same time, Figure 2 As shown, since the directions of the aeration nozzles 114 of the self-rotating aeration module 1 are arranged counterclockwise or clockwise, the purification device will rotate under the traction of the self-rotating aeration module 1. At this time, the strip biological filter membrane 33 disturbs the silt deposited at the bottom of the water body, accelerates the release process of nutrients in the silt, provides sufficient nutrient matrix for emergent plants and microorganisms carried by the biological filter membrane, promotes the growth of emergent plants and the reproduction of microorganisms, thereby strengthening the purification of water bodies and bottom mud. When in use, the purification device can be directly placed in the water body. This technical solution enhances the purification effect of the ecological floating bed system on the water body, and forms a three-dimensional pattern of purified water quality with aquatic plants on the top and biological filter membranes on the bottom. At the same time, the stirring function of the bottom silt is increased, which prompts the aquatic plants and biofilm carriers to effectively absorb the bottom silt, prevents the silt from being continuously and stably deposited on the bottom of the water, and gradually forms endogenous pollution, which is very suitable for environments with weak hydrodynamics.

[0025] The embodiments described above are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, a person skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be included in the protection scope of the present application.
