[0039] Example
[0040] This embodiment provides a microbial carrier for wastewater treatment, referring to... Figure 1 As shown, it includes a first sphere 1, a second sphere 2, and a third sphere 3.
[0041] Reference Figure 3As shown, the first sphere 1 is hollow inside and has a first through hole on its surface. Specifically, the first sphere 1 can be configured as a grid structure, allowing water to flow through the first through hole inside and outside the sphere 1. The first sphere 1 has a connecting portion 11, which includes multiple first elastic plates 12. These multiple first elastic plates 12 form a storage channel, the diameter of which gradually decreases from the outside of the first sphere 1 towards its center. Specifically, the storage channel can be formed into a conical shape, creating gaps between the first elastic plates 12, thereby expanding the first elastic plates 12 and increasing the diameter of the storage channel.
[0042] Reference Figure 5 As shown, the second sphere 2 is hollow inside and has a second through hole on its surface. Specifically, the second sphere 2 can also be configured as a grid structure, allowing water to flow through the second through hole inside and outside the first sphere 1. The second sphere 2 has a connection port 21, into which the connecting part 11 is inserted. By inserting the connecting part 11 into the connection port 21, the relative position of the first sphere 1 and the second sphere 2 can be limited.
[0043] Reference Figure 7 As shown, the third sphere 3 is hollow inside and has a third through hole on its surface. This allows water to flow through the third through hole between the inside and outside of the third sphere 3. The third sphere 3 is located inside the second sphere 2, specifically by expanding the first elastic sheet 12 and loading the third sphere 3 into the second sphere 2 through the placement channel.
[0044] The microbial carrier for wastewater treatment provided in this embodiment adopts a three-layer spherical structure to increase the specific surface area, thereby improving biofilm formation efficiency and wastewater treatment efficiency. By providing a connecting part 11 on the first sphere 1 and inserting it into the connecting port 21, the relative positions of the first sphere 1 and the second sphere 2 can be restricted. On the other hand, the third sphere 3 loaded with microbial filler can be placed inside the second sphere 2 by expanding the first elastic sheet 12, thereby realizing the addition of microbial filler when the microbial carrier is in use, making it more convenient to use.
[0045] Specifically, continue to refer to Figure 3 As shown, the connecting part 11 also includes a connecting shaft 13. One end of the connecting shaft 13 is connected to the first sphere 1, and the other end is connected to the first elastic sheet 12. A connecting ring 22 is provided on the connecting port 21, and the connecting shaft 13 is rotatably connected to the connecting ring 22. This allows the first sphere 1 and the second sphere 2 to rotate relative to each other around the axis, thereby improving the contact effect between the water flow and microorganisms and further improving the purification efficiency.
[0046] Specifically, the connecting shaft 13 includes a first part 14 and a second part 15, wherein the outer diameter of the first part 14 is smaller than the outer diameter of the second part 15; the first part 14 is inserted into the connecting ring 22 and abuts against the inner wall of the connecting ring 22, and the second part 15 abuts against the end face of the connecting ring 22. This better limits the relative position between the first sphere 1 and the second sphere 2, ensuring that only the first sphere 1 and the second sphere 2 rotate around an axis.
[0047] Specifically, the first sphere 1 has two connecting portions 11 arranged coaxially and opposite to each other along its center; the second sphere 2 has connecting ports 21 corresponding to the connecting portions 11. The arrangement of two opposing connecting portions 11 and two corresponding connecting ports 21 allows for better assembly of the first sphere 1 and the second sphere 2, ensuring relative positioning of the first sphere 1 and the second sphere 2 and guaranteeing relative rotation of the first sphere 1 and the second sphere 2 around the axes of the two connecting portions 11.
[0048] Specifically, refer to Figure 2 As shown, a filler material 4, which is permeable to water, is filled between the second sphere 2 and the third sphere 3. It should be noted that, in order to clearly show the three-layer spherical structure of the microbial carrier, [the following text is incomplete and requires further context: "In the diagram, in ... Figure 1 The filling material 4 is not shown. By placing the filling material 4 between the second sphere 2 and the third sphere 3, as microorganisms continuously attach and grow on the microbial carrier, the carrier can form aerobic, anoxic, and anaerobic zones from the outside to the inside, allowing for simultaneous aerobic, anoxic, and anaerobic biochemical reactions. This is beneficial for enhancing the biological nitrogen removal effect of nitrification and denitrification. The facultative anaerobic quorum sensing bacteria fixed inside can produce AHL under aerobic, anoxic, and anaerobic conditions, playing a role throughout the biofilm formation process, promoting the colonization and growth of functional microorganisms, increasing the diversity and stability of the microbial community, and ultimately improving the treatment efficiency of the wastewater treatment equipment.
[0049] Specifically, in this embodiment, the filling material 4 can be one or both of sponge and polyurethane cotton. The filling material 4 consists of multiple unit blocks, which can be inserted from the placement channel into the second sphere 2 by expanding the first elastic sheet 12, positioning it between the second sphere 2 and the third sphere 3. The selected filling material 4 has a porosity of 90-95% and a density of 0.95-0.98 g / cm³. 3 .
[0050] Specifically, refer to Figure 4 , Figure 6 , Figure 8As shown, the first sphere 1 includes two first hemispheres 16, each with a staggered first fastener 17 and a first fastening groove 18 on its end face; the two first hemispheres 16 are fastened together by the first fastener 17 and the first fastening groove 18. The second sphere 2 includes two second hemispheres 23, each with a staggered second fastener 24 and a second fastening groove 25 on its end face; the two second hemispheres 23 are fastened together by the second fastener 24 and the second fastening groove 25. The third sphere 3 includes two third hemispheres 33, which are bonded or welded together. The first sphere 1, the second sphere 2, and the third sphere 3 can each be fastened together, bonded, or welded using a hemispherical structure, allowing each sphere to be manufactured using a single mold, reducing production difficulty and cost.
[0051] Specifically, refer to Figure 7 As shown, the third sphere 3 has multiple through grooves 31, which intersect at a point to divide the third sphere 3 into multiple second elastic plates 32. By pressing the second elastic plates 32, the gap between the second elastic plates 32 can be widened, thereby allowing the filler to be loaded into the third sphere 3, achieving post-filling.
[0052] Specifically, the first sphere 1 has a diameter of 10-12 cm, the second sphere 2 has a diameter of 4-6 cm, and the third sphere 3 has a diameter of 1-2 cm. The filler loaded in the third sphere 3 is immobilized microspheres with a diameter of 3-4.5 mm, and each third sphere 3 contains 10-15 immobilized microspheres.
[0053] Usage process: After producing the first sphere 1 and the second sphere 2, rotate the two second hemispheres 23 relative to each other by a certain angle so that the second buckle 24 is inserted into the second buckle groove 25, and the two second hemispheres 23 are fastened together to form the second sphere 2; then rotate the two first hemispheres 16 relative to each other by a first angle so that the first buckle 17 is inserted into the first buckle groove 18, and insert the connecting part 11 into the connecting port 21 so that the two first hemispheres 16 are fastened together to form the first sphere 1, and the second sphere 2 is wrapped inside the first sphere 1.
[0054] In use, first open the second elastic sheet 32 on the surface of the third sphere 3, put the filler into the inside of the third sphere 3, and after releasing, the second elastic sheet 32 resets to prevent the filler from coming out; then open the first elastic sheet 12, put the third sphere 3 and the filler material 4 into the second sphere 2 through the placement channel, and after releasing, the first elastic sheet 12 resets to prevent the third sphere 3 and the filler material 4 from coming out.
[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0056] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
