Figure 1 and Figure 2 The ecological riverbed structure based on microbial governance includes a silt layer 1, a fixed layer 2 and an attachment structure 3. In this embodiment, the water in the river is polluted, and the method of using microorganisms to decompose pollutants is used to treat the river water. Pollutants can be organic matter, ammonia nitrogen, nitrite and other substances that can affect water quality; in this embodiment, the river water is a eutrophic body, and this embodiment uses microorganisms to decompose organic matter, ammonia nitrogen and other substances in the river to achieve the effect of treating the river water quality.
[0036] Reference Figure 1 and Figure 2 The silt layer 1 is the original structure of the riverbed, the fixed layer 2 is arranged on the silt layer 1, the attachment structure 3 is fixed on the fixed layer 2, and the attachment structure 3 is immersed in the water body. The attachment structure 3 is used for microorganisms to be adsorbed and fixed; thus, it is conducive to the growth and reproduction of microorganisms to purify the water quality of the river water body.
[0037] Reference Figure 2 and Figure 3 The fixing layer 2 includes a plurality of fixing bars 21, and a plurality of column fixing bars 21 are arranged at intervals along the flow direction of the water body, and channels for water flow are arranged between the fixing bars 21. The attachment structure 3 is fixed on the fixing bars 21, and the fixing bars 21 are arranged on the periphery of the attachment structure 3. The fixing bars 21 lift the attachment assembly 33, so that there is a gap between the attachment structure 3 and the sludge layer 1 for water flow, so that microorganisms can be adsorbed on the attachment structure 3, and the contact area between the attachment structure 3 and the water body is also expanded, so that the microorganisms on the attachment structure 3 can be used to decompose pollutants in the water body.
[0038] Reference Figure 2 and Figure 3In this embodiment, the flow direction of the water body flows from the lower left to the upper right; at the same time, two groups of fixed bars 21 are provided, and each group of fixed bars 21 includes two fixed bars 21 arranged opposite to each other, and along the flow direction of the water body, the distance between the two fixed bars 21 arranged opposite to each other decreases. The fixed bars 21 include a plurality of mass blocks 211, and the plurality of mass blocks 211 are located on the same straight line. The plurality of mass blocks 211 are laid on the silt layer 1, and the attachment structure 3 is fixed on the mass blocks 211. Therefore, when the water body in the river flows through the fixed layer 2 and the adsorption structure, when the water body flows through the channel between the fixed bars 21 arranged opposite to each other, the water body will be decelerated, which is conducive to the contact between the microorganisms and the pollutants in the water body, and improves the decomposition effect of the microorganisms on the pollutants in the water body.
[0039] Reference Figure 2 and Figure 3 In this embodiment, the mass block 211 is a sandbag, and the attachment structure 3 is plugged and fixed to the mass block 211 to facilitate the construction of the fixed layer 2. In other embodiments, the mass block 211 includes a gabion mesh and a plurality of stone pieces, the stone pieces are arranged in the gabion mesh, and the attachment structure 3 is tied and fixed to the mass block 211; the mass block 211 using stone pieces has a plurality of grooves and internal channels on the surface, so as to further reduce the flow rate of the water body. The staff can place the mass block 211 on the silt layer 1 by hoisting.
[0040] Reference Figure 4 and Figure 5 The attachment structure 3 includes a mounting frame 31, a guide plate 32 and an attachment assembly 33; the mounting frame 31 is fixed by plugging or binding with the mass block 211, and the attachment assembly 33 is fixed on the mounting frame 31, and the attachment assembly 33 is used for microorganisms to attach. The guide plate 32 is fixed on the water supply side of the mounting frame 31; the guide plate 32 and the attachment assembly 33 are located on the same horizontal plane.
[0041] Reference Figure 4 In this embodiment, the guide plate 32 is an arc-shaped plate, the opening direction of the guide plate 32 is away from the incoming water direction, and a plurality of water-permeable holes 321 for the water body to penetrate are opened on the guide plate 32. Therefore, the water body can flow to the attachment component 33 through the water-permeable holes 321. At the same time, the guide plate 32 can block the suspended matter in the river water body, thereby guiding the suspended matter in the water body to the two sides of the attachment component 33, and reducing the accumulation of suspended matter in the water body to the attachment component 33.
[0042] Reference Figure 4 and Figure 5 , there are a plurality of attachment assemblies 33, and the plurality of attachment assemblies 33 are arranged vertically at intervals. In this embodiment, two attachment assemblies 33 are arranged vertically, and there is a distance between the bottom attachment assembly 33 and the fixed layer 2. There is an avoidance gap between adjacent attachment assemblies 33, so that water can pass between the two attachment assemblies 33.
[0043] Reference Figure 4 and Figure 5 The attachment assembly 33 includes a hollow installation tube 331 and a hollow tube membrane 332. Two installation tubes 331 are provided. The two installation tubes 331 are arranged opposite to each other, and the installation tubes 331 are fixedly connected to the installation frame 31. The installation tubes 331 are externally connected to an air pump. Therefore, oxygen can be transported to the installation tubes 331 and the tube membrane 332 through the air pump, which is beneficial to the growth and reproduction of microorganisms and improves the ability of microorganisms to decompose pollutants in the river.

Figure 6 The tube membrane 332 includes a hollow air-permeable membrane 3321 and a bio-membrane 3322. The bio-membrane 3322 is arranged on the periphery of the air-permeable membrane 3321. The bio-membrane 3322 is used for supplying. The air-permeable membrane 3321 is connected to the installation tube 331. The gas penetrates into the bio-membrane 3322 through the installation tube 331 and the air-permeable membrane 3321 in sequence, which is beneficial to the growth and reproduction of aerobic microorganisms and improves the purification effect of microorganisms on water bodies.
[0045] The staff can release microorganisms into the river water by directly releasing the microorganisms into the river water; or release the microorganism strains into the attachment component 33 and then immerse the attachment structure 3 into the river water.
