Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a novel self-trophic denitrification packing material. Background Technology

[0002] In the process of wastewater treatment, in order to improve the efficiency of denitrification biological reaction, packing balls, as a filling medium, have been widely used in wastewater reactors.

[0003] However, the existing single packing ball design is not sufficient to optimize the contact time and reaction effect between fluid and microorganism in some cases, especially in wastewater treatment processes that require high-efficiency reactions. Therefore, how to effectively improve mixing and reaction efficiency is a technical problem that urgently needs to be solved.

[0004] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is the closest prior art. Utility Model Content

[0005] The purpose of this invention is to address the above-mentioned shortcomings and provide a novel autotrophic denitrification packing.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a novel self-atrophic denitrification packing material, comprising packing balls for filling in a wastewater reactor, wherein the packing balls are provided with two communicating ports;

[0007] A spiral channel is disposed inside the packing ball and runs through the centerline path between the two openings, so as to allow the sewage fluid to flow along the path of the spiral channel and increase the contact frequency of the fluid inside the packing ball;

[0008] A loop channel assembly is disposed inside the packing ball and communicates with the spiral channel to increase the residence time of the sewage fluid inside the packing ball, thereby fully reacting the pollutants in the sewage fluid.

[0009] The attachment zone, located on the outer surface of the packing ball, is used to attach denitrifying microorganisms and form a microbial community.

[0010] Furthermore, the loop channel group includes a first loop channel, a second loop channel, and a third loop channel located on the xoy plane, xoz plane, and yoz plane where the packing ball is located, respectively. The first loop channel, the second loop channel, and the third loop channel are arranged in two or more at intervals from the outside to the inside on the corresponding plane.

[0011] Furthermore, the outer surface of the packing ball is uniformly provided with several first annular spacers around the y-axis, and the outer surface of the packing ball is also uniformly provided with several second annular spacers around the z-axis. The several first annular spacers and the several second annular spacers are staggered on the outer surface of the packing ball. The attachment area is provided in multiple ways, including areas that are staggered and separated by several first annular spacers and several second annular spacers.

[0012] Furthermore, the cross-sections of the first annular spacer and the second annular spacer are trapezoidal.

[0013] Furthermore, the wastewater reactor filled with packing balls is located in an anaerobic or non-anaerobic environment.

[0014] Compared with existing technologies, this invention has the following advantages: The spiral channel and loop channel group allow the flow direction of wastewater fluid within the packing balls to change, enhancing the mixing effect through rotational flow. This ensures sufficient contact between the wastewater fluid and the packing balls, promoting the reaction. It is suitable for reaction systems requiring thorough mixing. Furthermore, the loop channel group structure extends the residence time of the wastewater fluid within the packing balls, helping to increase reaction time or mass exchange time, thereby improving the reaction efficiency. Additionally, the attachment zone increases the specific surface area of ​​the packing balls, facilitating the attachment of denitrifying microorganisms. These microorganisms secrete extracellular polymers to form a biofilm, creating a microbial community on the surface of the packing balls. This effectively utilizes the nitrates and organic matter surrounding the packing balls, enhancing the efficiency of the denitrification reaction. Attached Figure Description

[0023] like Figure 1-5 As shown, this utility model discloses a novel self-atrophic denitrification packing material, including packing balls 1 for filling in a wastewater reactor, wherein the packing balls 1 are provided with two communicating ports 2;

[0024] The spiral channel 3 is disposed inside the packing ball 1 and runs through the centerline path between the two openings 2, so as to allow the sewage fluid to flow along the path of the spiral channel 3 and increase the contact frequency of the fluid inside the packing ball 1.

[0025] The loop channel assembly is located inside the packing ball 1 and communicates with the spiral channel 3, which is used to increase the residence time of the sewage fluid in the packing ball 1 and fully react the pollutants in the sewage fluid.

[0026] The attachment zone is set on the outer surface of the packing ball 1 and is used to attach denitrifying microorganisms to form a microbial community.

[0027] In specific implementation, by opening two openings 2 on the surface of the packing ball 1 and opening a spiral channel 3 inside the packing ball 1 along the center line between the two openings 2, the sewage fluid flows along the path of the spiral channel 3, which enhances the contact between the sewage fluid and the packing ball 1 and promotes the reaction.

[0028] The loop channel group, which is connected to the spiral channel 3 and is opened inside the packing ball 1, increases the residence time of the sewage fluid in the packing ball 1, fully reacts the pollutants in the sewage fluid, helps to increase the reaction time or the mass exchange time, and further improves the reaction effect.

[0029] The attachment zone created on the outer surface of the packing ball 1 allows denitrifying microorganisms to attach and form a microbial community, effectively utilizing the nitrates and organic matter around the packing ball 1, which helps to enhance the efficiency of the denitrification reaction.

[0030] It should be noted that the distance between the two openings 2 is the diameter of the packing ball 1.

[0031] In one embodiment, the loop channel group includes a first loop channel 4, a second loop channel 5, and a third loop channel 6 located on the xoy plane, xoz plane, and yoz plane where the packing ball 1 is located, respectively. Two or more of the first loop channel 4, second loop channel 5, and third loop channel 6 are arranged sequentially from the outside to the inside on the corresponding planes. This design, by establishing the first loop channel 4, second loop channel 5, and third loop channel 6 on the spiral channel 3 and respectively on the xoy plane, xoz plane, and yoz plane within the packing ball 1, connects the inlet and outlet of the spiral channel 3, forming a loop, extending the residence time of the wastewater fluid inside the packing ball 1, and improving the reaction effect.

[0033] In one embodiment, the cross-sections of the first annular spacer 7 and the second annular spacer 8 are trapezoidal. This design, using trapezoidal cross-sectional shapes for the first annular spacer 7 and the second annular spacer 8, forms an outwardly expanding guiding surface, guiding the flow path of the sewage fluid.

[0034] In one embodiment, the wastewater reactor filled with the packing balls 1 is placed in an anaerobic or anoxic environment. This design promotes microbial growth and denitrification by creating an anaerobic or anoxic environment inside the wastewater reactor filled with the packing balls 1.
