Description

Technical Field

[0001] This utility model belongs to the field of MBBR biological packing technology, and specifically relates to MBBR packing for recirculating aquaculture. Background Technology

[0002] Existing wastewater treatment methods mostly employ microbial processes. These microorganisms need to reside on biological packing materials to purify the wastewater. Current biological packing materials are generally disc-shaped, consisting of multiple concentric rings and connecting ridges. The connecting ridges and concentric rings form a passageway for wastewater, facilitating microbial attachment and growth. However, due to the equidistant arrangement of the concentric rings 1 and connecting ridges 2 (e.g., ... Figure 2 As shown in the figure, the water passage cavity far from the central axis of the concentric ring is larger than the water passage cavity close to the central axis of the concentric ring, resulting in the specific surface area of ​​the external water passage cavity being larger than that of the internal water passage cavity. Therefore, there is a need to improve and increase the specific surface area of ​​existing biological packing materials. Thus, we hope to design an MBBR biological packing material with a novel structure to solve this problem. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide MBBR packing material for recirculating aquaculture, and to solve the problems mentioned in the background art.

[0005] The concentric ring 1 has a ridge 1 integrally formed from top to bottom, and the concentric ring 1 has a ridge 2 formed from left to right inside.

[0006] In a preferred embodiment, the diameter of the first concentric ring is smaller than the diameter of the second concentric ring, the diameter of the first concentric ring is 6.6 cm, and the diameter of the second concentric ring is smaller than the diameter of the third concentric ring, the diameter of the second concentric ring is 12.6 cm.

[0007] In a preferred embodiment, the diameter of the second concentric ring is smaller than the diameter of the third concentric ring, which has a diameter of 18.6 cm. The diameter of the third concentric ring is also smaller than the diameter of the fourth concentric ring, which has a diameter of 24.6 cm.

[0008] In a preferred embodiment, the diameter of the concentric ring four is smaller than the diameter of the lace ring, and the diameter of the lace ring is 30cm.

[0009] In a preferred embodiment, the diameters of the concentric rings one, two, three, four and the lace ring gradually increase, and the spacing between each layer of the concentric rings one, two, three, four and the lace ring is 6cm. The concentric rings one, two, three, four and the lace ring are evenly distributed, and together with the ribs one, two and the evenly distributed supports one, two, three and four, the area difference between each water passage cavity is minimized as much as possible, saving manufacturing materials while ensuring specific surface area.

[0010] In a preferred embodiment, the second rib and the first rib are arranged in a cross shape, and the intersection of the second rib and the first rib coincides with the center of the concentric rings one, two, three, four and the lace ring. The width of the second rib and the first rib is 0.35cm.

[0011] In a preferred embodiment, the first rib divides the concentric rings one, two, three, four and the lace ring into two equally divided regions, and the two regions are arranged in an axially symmetrical structure.

[0012] In a preferred embodiment, the width of the lace ring is 0.5cm, and thirty-two equally spaced support bars are provided between the inner side of the lace ring and the outer side of the concentric ring four in each region.

[0013] In a preferred embodiment, twelve equally spaced supports are provided between concentric ring one and concentric ring two, eighteen equally spaced supports are provided between concentric ring two and concentric ring three, and twenty-four equally spaced supports are provided between concentric ring three and concentric ring four.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are: by setting evenly distributed concentric ring one, concentric ring two, concentric ring three, concentric ring four and lace ring evenly distributed, the area difference between each water passage cavity is reduced as much as possible, saving manufacturing materials while ensuring specific surface area.

[0015] By setting rib one, rib two, and evenly distributed support rib one, support rib two, support rib three, and support rib four, concentric ring one, concentric ring two, concentric ring three, and concentric ring four, as well as the lace ring, and dividing the space between them into multiple water-permeable cavities with relatively small area differences, it is possible not only to reduce the area of ​​the outermost water-permeable cavity and increase the strength of the lace ring, but also to increase the specific surface area of ​​the entire structure without increasing the diameter of the entire structure, thus saving space and increasing the amount of microorganisms attached.

[0022] The concentric ring 110 has a single ridge 170 integrally arranged from top to bottom, and the concentric ring 110 has a second ridge 170 arranged from left to right inside.

[0023] Please see Figure 1 The diameter of concentric ring 110 is smaller than the diameter of concentric ring 2120, with a diameter of 6.6 cm. The diameter of concentric ring 2120 is smaller than the diameter of concentric ring 3130, with a diameter of 12.6 cm.

[0025] The diameter of the concentric ring 140 is smaller than the diameter of the lace ring 150, which has a diameter of 30cm.

[0026] The diameters of concentric rings 110, 120, 130, 140, and 150 gradually increase, with a spacing of 6cm between each layer. These concentric rings are evenly distributed, complementing the ridge strips 160 and 160. 70 and evenly distributed supports 111, 121, 131, and 141 minimize the area difference between the various water passages, saving materials while ensuring that the specific surface area of ​​the water passages is such that concentric rings 110, 120, 130, and 140, as well as the lace ring 150, form holes with the ribs 160, 170, 111, 121, 131, and 141.

[0027] As the first embodiment of this utility model, by setting concentric ring 110, concentric ring 2120, concentric ring 3130, concentric ring 4140 and lace ring 150, in actual use, since the spacing between concentric ring 110, concentric ring 2120, concentric ring 3130, concentric ring 4140 and lace ring 150 is 6cm, the evenly distributed concentric ring 110, concentric ring 2120, concentric ring 3130, concentric ring 4140 and lace ring 150 minimize the area difference between each water passage cavity, saving manufacturing materials while ensuring specific surface area.

[0028] Please see Figure 1 Ribbon 2 170 and rib 1 160 are arranged in a cross shape, and the intersection of rib 2 170 and rib 1 160 coincides with the center of concentric ring 1 110, concentric ring 2 120, concentric ring 3 130, concentric ring 4 140 and lace ring 150. The width of rib 2 170 and rib 1 160 is 0.35cm.

[0029] Rib 160 divides concentric ring 110, concentric ring 2 120, concentric ring 3 130, concentric ring 4 140 and lace ring 150 into two equally divided areas, and the two areas are arranged in an axially symmetrical structure.

[0030] The width of the lace ring 150 is 0.5cm. In each area, the inner side of the lace ring 150 and the outer side of the concentric ring 4 140 are provided with thirty-two equally spaced support bars 4 141.

[0031] Twelve equally spaced supports 111 are provided between concentric ring 110 and concentric ring 220; eighteen equally spaced supports 121 are provided between concentric ring 220 and concentric ring 330; and twenty-four equally spaced supports 131 are provided between concentric ring 330 and concentric ring 440.

In actual use, this design can not only reduce the area of ​​the outermost water passage cavity and increase the strength of the lace ring 150, but also help to increase the specific surface area of ​​the entire structure without increasing the diameter of the entire structure, saving space and increasing the amount of microorganisms attached.
