Description

Technical Field

[0001] This utility model relates to the field of biogas biological packing technology, and in particular to a combined biological packing module. Background Technology

[0002] Contact oxidation, as one of the mainstream technologies in wastewater treatment, relies heavily on the performance of biological packing materials for its core efficiency. As the carrier for microbial attachment and metabolism, biological packing materials directly influence the growth, reproduction, and detachment of microorganisms, thus playing a decisive role in wastewater treatment efficiency, system energy consumption, infrastructure investment costs, and operational stability and reliability. With the rapid development of the synthetic plastics industry and in-depth research by domestic and international researchers on the structure, formation mechanism, and growth kinetics of biofilms, biological packing materials have undergone multiple generations of updates, continuously enhancing their biofilm attachment capabilities and driving the continuous improvement of contact oxidation treatment efficiency. Currently, the mainstream biological packing materials on the market include various types such as combined packing materials, elastic packing materials, suspended ball packing materials, and braided packing materials. Among them, suspended packing materials have dominated the wastewater biological treatment packing material market due to their significant advantages such as simple structure, low cost, large specific surface area, resistance to clogging, and resistance to shock loads.

[0003] Suspended packing materials typically require both ends to be secured to various supports within the wastewater treatment tank for installation. Common types include soft packing, semi-soft packing, combined packing, and elastic three-dimensional packing. However, these types of packing materials face unavoidable technical challenges in practical applications, primarily in the construction and maintenance phases. Firstly, the installation of the packing supports and the binding of the packing materials must be completed within the confines of the wastewater tank. Limited by the tank structure and narrow working space, construction is extremely inconvenient, resulting in slow construction speeds, difficulty in effectively controlling construction quality, and non-compliance with the tank's internal dimensions. Secondly, the humid and corrosive environment within the tank can lead to unstable corrosion treatment of the supports, triggering a series of cascading failures, such as collapse due to decreased support structural strength or breakage of the packing material's central rope due to uneven stress or entanglement. More seriously, when such failures occur, the limited working conditions within the tank often prevent maintenance personnel from safely entering for repairs, ultimately leading to the scrapping of a large amount of packing material. This not only increases wastewater treatment costs but also severely impacts the continuous and stable operation of the treatment system.

[0004] For small and medium-sized contact oxidation systems, the aforementioned shortcomings of existing suspended packing materials are particularly prominent, becoming a key bottleneck restricting the efficient and economical operation of such wastewater treatment systems. Therefore, a biological packing material structure that can avoid complex construction within the tank, improve structural stability, and facilitate operation and maintenance has become a pressing technical problem to be solved in the industry.

[0021] The following is a detailed explanation with reference to the accompanying drawings.

[0022] Example 1

[0023] This utility model provides a combined biological packing module, such as Figures 1 to 3As shown, the system includes several modular bodies 100 for placement in a wastewater tank. Each modular body 100 is composed of several frames. A male socket 101 is provided on one side of each modular body 100. A female socket 102, corresponding to the male socket 101, is provided on the other side of each modular body 100 away from the male socket 101. Several support assemblies 200 are provided inside each modular body 100. Each support assembly 200 includes a support rod 201, packing material 202, and a central rope 203 for connecting the packing material 202. The central ropes 203 extend vertically and are arranged from top to bottom within the modular body 100, evenly distributed on a horizontal plane. As the core facility of the contact oxidation method, the installation quality and structural stability of the biological packing material directly determine the wastewater treatment efficiency and system lifespan. The modular structural design of this utility model precisely solves the industry pain points of traditional suspended packing materials, such as "limited construction within the tank and difficulty in ensuring quality," with technical effects reflected in three dimensions. Firstly, several main modules 100 are prefabricated in the factory, allowing for flexible on-site combination according to the length and width of the sewage tank. This replaces the traditional scattered installation of fillers within the tank, avoiding the problem of limited construction space from the source. Secondly, the corresponding design of the male socket 101 and female socket 102 enables rapid socket-type splicing, eliminating the need for complex connection operations within the tank. This completely avoids cross-construction during the installation of the contact oxidation system, significantly improving construction speed and quality, and reducing potential risks such as unstable corrosion resistance. Thirdly, the regular arrangement of the central rope 203 in the support assembly 200 ensures the uniform distribution of the filler 202. This retains the advantage of the large specific surface area of ​​suspended fillers while solving the problem of mutual bending and breakage of the central ropes in traditional fillers. At the same time, it provides ample space for microbial attachment, ensuring sewage treatment efficiency.

[0024] It should be noted that the male and female sockets of this utility model are only used for limiting and are not for a fully snap-fit ​​connection. This avoids the cumbersome operation of unsnap and is only used for limiting during assembly.

[0025] According to a preferred embodiment, a plurality of support rods 201 are located at the vertical upper and lower ends of the module body 100, respectively. The two ends of the support rods 201 are connected to the side frames of the module body 100. Addressing the core problem of "collapse due to poor support installation quality" commonly found in traditional packing materials, this design forms a stable support system through the scientific arrangement of the support rods 201, achieving outstanding technical results. The support rods 201 are located at the upper and lower ends of the module body 100 and are rigidly connected to the side frames, constructing a vertical support structure that bears load across the entire area. Compared to traditional temporary supports erected within the tank, the load-bearing stability is significantly improved, effectively resisting the impact of sewage and the load from the self-weight of the packing material 202, thus structurally avoiding the risk of support collapse.

[0026] According to a preferred embodiment, a plurality of support rods 201 are evenly arranged along the width direction of the module body 100. A plurality of support rods 201 located at the vertical upper end of the module body 100 are correspondingly arranged with a plurality of support rods 201 located at the vertical lower end of the module body 100, and each support rod 201 located at the vertical upper end of the module body 100 and its corresponding support rod 201 located at the vertical lower end of the module body 100 are connected by a plurality of central ropes 203 arranged at intervals along the extension direction of the support rod 201. This optimized design improves system reliability by addressing structural regularity, resulting in a dual enhancement of technical effectiveness. In terms of structural stability, the support rods 201 are evenly arranged along the width of the module body 100 and correspond one-to-one with each other to form a symmetrical grid support system. Compared with traditional scattered supports, the force is more balanced and can be adapted to fillers 202 of different weights and specifications, avoiding support deformation caused by uneven load. In terms of functional efficiency, the central ropes 203 arranged at intervals between the upper and lower support rods 201 form an orderly array, which completely solves the problem of messy mutual bending of the central ropes of traditional fillers. At the same time, it ensures that the density of the filler 202 is controllable and the distribution is uniform, reducing the risk of filler scrapping due to breakage of the central rope. It is especially suitable for the stable operation requirements of small and medium-sized contact oxidation systems.

[0027] According to a preferred embodiment, a central rope 203 suspends several packing materials 202 from top to bottom. The upper and lower ends of the central rope 203 are connected to support rods 201, respectively. This invention achieves dual optimization of function and maintenance through the connection method between the central rope 203 and the packing materials 202. Functionally, the way the central rope 203 suspends the packing materials 202 from top to bottom allows them to hang naturally, retaining the advantages of suspended packing materials being less prone to clogging and resistant to impact loads, while avoiding accumulation and compression that could affect microbial contact, thus maximizing biodegradation efficiency. In terms of maintenance, the simple connection structure between the central rope 203 and the support rods 201, combined with the feature that the module can be completely removed from the tank, completely solves the problem of traditional packing materials being "unable to be repaired inside the tank"—when the packing materials 202 age or become clogged, the entire module can be removed for repair, eliminating the need for work inside the tank, reducing maintenance difficulty and downtime costs, and avoiding overall scrapping due to partial damage.

[0028] According to a preferred embodiment, the frame of the module body 100 includes at least an upper vertical bar 103, a plurality of lower vertical bars 104, and a frame 105. The frame 105 forms the edge frame of the module body 100. The upper vertical bar 103 and the plurality of lower vertical bars 104 are located at the vertical upper and lower vertical lower ends of the frame 105, respectively, for auxiliary support. A male socket 101 and a female socket 102 are located on opposite sides of the frame 105, and the male socket 101 and the female socket 102 are arranged to penetrate the frame 105 from top to bottom. This frame design achieves a dual improvement in strength and workability through structural reinforcement and optimized connections. In terms of structural strength, the frame 105, upper longitudinal bar 103, and lower longitudinal bar 104 form a complete load-bearing system. Compared with traditional temporary supports, the deformation resistance is significantly enhanced, and it can withstand the long-term operating load of small and medium-sized contact oxidation systems, avoiding the collapse of the support due to structural weakness. In terms of connection reliability, the design of the male socket 101 and female socket 102 penetrating the frame 105 makes the module splicing and interlocking deeper, and the overall rigidity stronger. At the same time, this factory-prefabricated connection structure replaces on-site welding or binding in the pool, effectively ensuring the stability of anti-corrosion quality, reducing the risk of sewage leakage and structural corrosion, and extending the service life of the system.

[0029] According to a preferred embodiment, the frame of the module body 100 further includes a fixing rod 106. The fixing rod 106 is located at the vertical lower end of the frame 105. The fixing rod 106 divides the vertical height of the frame 105 into a 5:2 ratio in the vertical direction for fixing the support rod 201. The fixing rod 106 divides the vertical height of the frame 105 into a 5:2 ratio, leaving sufficient gaps and reserving space for the aeration assembly 300. The clear dimensional proportions provide a basis for standardized production in the module factory, ensuring that all components are precisely fitted, replacing the rough mode of traditional on-site measurement and processing in the pool, improving the stability of construction quality from the source, and avoiding installation problems and structural hazards caused by component size deviations.

[0030] According to a preferred embodiment, an aeration assembly 300 is provided vertically below the fixing rod 106. The aeration assembly 300 is connected to the lower vertical rod 104, and the aeration ports of the aeration assembly 300 are arranged from bottom to top and pass through the support assembly 200. The layout of the aeration ports "passing through the support assembly 200 from bottom to top" allows the bubbles to rise evenly and flow fully through the packing layer 202, solving the problem of uneven dissolved oxygen distribution caused by misalignment between traditional aeration and packing, providing sufficient oxygen for microbial metabolism, and enhancing the degradation effect; at the same time, the agitation effect of the bubbles can prevent the packing 202 from clogging, reduce the breakage of the central rope 203 due to uneven stress caused by packing caking, and further improve the stability of the system.

[0031] According to a preferred embodiment, the two ends of the support rod 201 are connected to the frames on both sides of the module body 100 by welding or erection. The flexible connection method of the support rod 201 precisely adapts to the construction needs of small and medium-sized contact oxidation systems, while solving the problems of "poor corrosion resistance and unreliable connection" in traditional supports. The high-strength characteristics of the connection ensure the structural stability of the module under long-term impact from sewage, avoiding the corrosion and collapse of supports caused by inadequate welding corrosion protection in traditional tanks.

[0032] According to a preferred embodiment, a plurality of central ropes 203 are parallel to each other. A plurality of support rods 201 are parallel to each other. The central ropes 203 and the support rods 201 are perpendicular to each other. The orthogonal arrangement of the central ropes 203 and the support rods 201 forms a regular grid structure, which allows the packing material 202 to be suspended in an orderly manner, completely avoiding rope entanglement, while ensuring smooth sewage flow, reducing resistance and dead zones, and improving treatment efficiency.

[0033] According to a preferred embodiment, the two ends of the central rope 203 are respectively connected to two support rods 201 by binding. The filler 202 is connected to the central rope 203 by tying.
