Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a two-layer three-dimensional wastewater treatment system. Background Technology

[0002] With the acceleration of urbanization and the expansion of industrial production, the demand for wastewater treatment is increasing, and the limitations of traditional wastewater treatment systems are becoming more and more prominent. Existing wastewater treatment systems mostly adopt a planar layout, dispersing process units such as equalization tanks, anaerobic tanks, aerobic tanks, and sedimentation tanks on the ground floor. This not only occupies a lot of land resources, but also, due to the limited planar space distribution, the pipeline connections between each unit are complex and the process is lengthy, resulting in prolonged hydraulic retention time and low wastewater treatment efficiency.

[0003] In urban core areas where land resources are scarce, traditional planar layout sewage treatment plants face severe challenges: on the one hand, the limited land area is difficult to meet the needs of expanding treatment scale, and large-scale land acquisition or process reconstruction is required for renovation and expansion, resulting in high construction costs and long cycles; on the other hand, the design mode of single-function tanks lacks flexibility, cannot dynamically adjust the process combination according to changes in water quality and quantity, and is difficult to adapt to the characteristics of complex composition and diverse treatment needs of industrial wastewater.

[0004] Therefore, there is an urgent need for a two-layer three-dimensional sewage treatment system that occupies a small area and has a high space utilization rate. Utility Model Content

Detailed Implementation

[0036] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0037] Example 1:

[0038] like Figure 1 As shown, this embodiment provides a two-layer three-dimensional sewage treatment system, including a mounting frame 1, multiple modular sewage treatment process units 2, and at least one geometric cylinder sewage treatment tank 3; the mounting frame 1 has two layers of installation space from top to bottom, and at least one modular sewage treatment process unit 2 is arranged in each layer of installation space; the geometric cylinder sewage treatment tank 3 is arranged on one side of the mounting frame 1; the multiple modular sewage treatment process units 2 and the geometric cylinder sewage tank 3 can be connected sequentially according to the sewage treatment process.

[0039] Specifically, the mounting frame 1 is designed with two-tiered installation space, significantly reducing the floor space required compared to traditional flat layouts. In urban areas where land resources are scarce, this system allows for the inclusion of more treatment units within limited land areas, greatly improving land use efficiency. Each installation space contains at least one modular wastewater treatment process unit 2, which, combined with the flexible arrangement of the geometric cylindrical wastewater treatment tank 3, enables the system to dynamically adjust the unit combination according to the actual treatment scale and wastewater type (such as adding or removing equalization tanks, switching wastewater biological treatment processes), adapting to diverse wastewater treatment needs (such as industrial wastewater, domestic sewage, etc.). Multiple modular wastewater treatment process units and geometric cylindrical wastewater treatment tanks are connected sequentially according to the process flow, resulting in shorter wastewater transmission paths and improved overall treatment efficiency. The mounting frame uniformly supports the modular wastewater treatment process units 2, greatly reducing civil engineering work, shortening the construction period, and reducing material waste and labor costs during construction compared to the construction of independent tanks in traditional decentralized layouts.

[0040] Furthermore, in this embodiment, the modular wastewater treatment process unit 2 is composed of functional segments in the wastewater treatment process flow, such as: modular intelligent secondary sedimentation equipment, modular deep treatment equipment, modular nitrification liquid reflux equipment, etc.

[0041] Optionally, the modular wastewater treatment process unit 2 can be an equalization tank, a bar screen, a sedimentation tank, or a power distribution room. The equalization tank balances water quality and quantity, buffers shock loads, and creates stable conditions for subsequent treatment; the sedimentation tank separates sludge and water, ensuring that the effluent meets standards. The modular wastewater treatment process unit 2 can cover the core processes of wastewater treatment. Through standardized module combinations, complete treatment processes (such as AOA, A² / O processes) can be quickly built, improving system versatility; each module can operate independently or be replaced, facilitating customized configurations for different water qualities (such as industrial wastewater and domestic sewage), enhancing system adaptability. Users can select module combinations according to the type of wastewater. For example, when treating low-concentration domestic sewage, a simplified process of equalization tank-biological treatment tank-sedimentation tank-disinfection tank can be used; when treating high-concentration industrial wastewater, wastewater treatment modules can be added or removed according to actual conditions to form a complete process adapted to high-concentration industrial wastewater. When a modular wastewater treatment process unit 2 malfunctions, the unit can be shut down for maintenance, and the function can be replaced by a backup modular wastewater treatment process unit 2 without affecting the operation of other units, thus reducing system downtime.

[0042] Furthermore, in this embodiment, a modular hall (not shown) can be optionally provided on the same side of the mounting frame 1 and the geometric cylinder wastewater treatment tank 3, forming a compact lateral layout of mounting frame 1-geometric cylinder wastewater treatment tank 3-modular hall, avoiding land waste caused by traditional decentralized multi-building systems. The hall adopts a modular design (such as prefabricated steel structure rooms), and units can be flexibly added or removed according to needs, making it suitable for urban areas or industrial parks with extremely scarce land resources. The hall is arranged on the same side as the mounting frame and geometric cylinder, shortening the interaction distance between personnel and equipment. Through the compact layout on the same side combined with modular functional integration, the space waste and inefficient coordination caused by the dispersion of treatment and auxiliary areas in traditional wastewater treatment systems are fundamentally solved. While ensuring functional integrity, the land occupation per unit treatment volume is minimized, while providing dual guarantees for operational efficiency and expansion flexibility, further strengthening the spatial compact concept of three-dimensional wastewater treatment systems. Specifically, the area occupied by the modular hall does not exceed 30% of the total area occupied by the system, so as to limit and avoid the modular hall from occupying too much space, and ensure that the layout of the modular sewage treatment process unit 2 and the geometric cylinder sewage treatment tank 3 is not squeezed, so as to achieve the integration of treatment and management in a limited space, which is especially suitable for urban or industrial park scenarios with tight land.

[0043] Furthermore, in this embodiment, the bottom installation space of the mounting frame 1 is located above ground. Both layers of the installation space are located above ground, with the bottom layer directly on the ground. The advantages of this solution are low construction difficulty, no need to excavate underground space, and it is especially suitable for areas with complex geological conditions (such as rocky areas and high water levels); equipment hoisting, maintenance, and repair are more convenient, and personnel can directly access the bottom unit through ground passages, reducing operation and maintenance costs; ventilation conditions are good, which is conducive to improving the aeration efficiency of aerobic processes such as aerobic tanks and reducing odor accumulation. Thus, the system can be set up according to different geographical environments and needs. By flexibly selecting the setting method of the bottom space, the system can adapt to different geological conditions, climate environments, and land resource conditions. This ensures the space utilization advantage of the two-layer three-dimensional layout and avoids the limitations of traditional fixed layouts (fully above ground or fully underground) in specific scenarios (such as high construction costs for fully underground and large land occupation for fully above ground), further enhancing the environmental adaptability and engineering feasibility of the system.

[0044] Furthermore, in this embodiment, the cross-sectional shape of the geometric cylindrical wastewater treatment tank 3 is circular or polygonal. When the geometric cylindrical wastewater treatment tank 3 adopts a circular cylinder, the structure is subjected to uniform stress, and the liquid pressure borne by all parts of the tank wall is the same, reducing stress concentration and lowering the wall thickness requirement. The circular geometric cylindrical wastewater treatment tank 3 can be divided into multiple uniformly distributed fan-shaped structures, with wastewater flowing up and down within the fan-shaped areas to complete biochemical treatment, saving land resources. For the same perimeter, the circular cross-sectional area is the largest, maximizing the tank volume; however, circular arrangements have corner gaps, making them suitable for individual installations or small-scale arrangements. When the geometric cylindrical wastewater treatment tank 3 adopts a polygonal cylinder, it is suitable for closely arranged scenarios, improving space utilization and reducing gap waste; the polygonal cylinder's foot structure can enhance overall rigidity; for example, a hexagonal cylinder has higher pressure resistance than a circular cylinder of the same area.

[0045] Furthermore, such as Figure 6 and Figure 7 As shown, in this embodiment, any two modular wastewater treatment process units 2 can be connected via a one-way wastewater pipe 41, and any modular wastewater treatment process unit 2 and the geometric cylinder wastewater treatment tank 3 can be connected via a one-way wastewater pipe 41. In this embodiment, a flow regulating valve 42 and a flow monitor 43 are installed on the one-way wastewater pipe 41. The one-way wastewater pipe 41 ensures that wastewater flows only in a preset direction, avoiding backflow caused by pressure fluctuations or operational errors. For example, a one-way pipe is installed between the anaerobic tank and the aerobic tank to prevent dissolved oxygen from the aerobic tank from entering the anaerobic tank, maintaining the stability of the anaerobic environment; between the sedimentation tank and the subsequent deep treatment unit, it prevents sludge from floating and causing deterioration of the effluent quality. The flow regulating valve 42 can adjust the flow rate in real time according to changes in influent water quality and quantity. For example, when the influent COD concentration suddenly increases, the flow rate entering the aerobic tank is automatically reduced to extend the hydraulic retention time and ensure sufficient degradation of organic matter; during low-flow periods at night, the flow rate is reduced to maintain the activated sludge concentration of each unit and prevent sludge loss. The flow rate in the pipeline is monitored in real time by the flow monitor 43.

[0046] Furthermore, such as Figures 2-5As shown, from a top-down view, the mounting frame 1 can be any of the following shapes: A straight line, suitable for long and narrow plots, facilitating construction and maintenance; the geometric cylindrical wastewater treatment tank 3 is located on one side of the mounting frame 1, utilizing corner space and avoiding conflicts with other facilities; an L-shape, suitable for corner areas of rectangular plots, utilizing 90° corner space to reduce floor space; the geometric cylindrical wastewater treatment tank 3 is located inside the mounting frame 1, shortening the connection distance with each modular wastewater treatment process unit 2 and reducing head loss; a U-shape, where the geometric cylindrical wastewater treatment tank 3 is located within the space enclosed by the mounting frame 1; or a quadrilateral shape, where the geometric cylindrical wastewater treatment tank 3 is located within the space enclosed by the mounting frame 1. U-shapes or quadrilaterals are suitable for square or near-square plots, forming a compact core-periphery structure with higher space utilization.

[0047] Furthermore, such as Figure 1 As shown, in this embodiment, the height of the geometric cylindrical wastewater treatment tank 3 does not exceed the top of the upper installation space and is not lower than the top of the lower installation space, significantly shortening the vertical transport distance of the pipelines between units, thereby reducing the head loss of liquid transport and saving energy. At the same time, this height range makes full use of the vertical gap between the two layers of the mounting frame, avoiding the tank height exceeding the overall three-dimensional layout range of the system or the waste of space due to insufficient height, effectively improving the space utilization efficiency of the two-layer three-dimensional system. Moreover, wastewater can flow naturally by gravity, reducing the frequency of forced pumping, and the pipeline connection does not need excessive bending, reducing the risk of blockage caused by pipeline complexity, and significantly enhancing the continuous stability of the wastewater treatment process.

[0048] Furthermore, such as Figure 6 As shown, in this embodiment, the modular wastewater treatment process unit 2 is equipped with a positioning component 21, an inlet pipe interface 22, and an outlet pipe interface 23. The modular wastewater treatment process unit 2 can be positioned on the mounting frame 1 via the positioning component 21. The inlet pipe interface 22 and the outlet pipe interface 23 are respectively connected to the inlet pipe and the outlet pipe. Specifically, in this embodiment, the positioning component 21 can be a guide pin, a slot, a positioning hole, etc., which can precisely cooperate with the corresponding structure on the mounting frame 1 (such as a positioning groove, bolt hole) to ensure the horizontal and vertical errors of the modular wastewater treatment process unit 2 during installation, avoiding rework caused by positioning deviations during traditional on-site pouring or hoisting. The inlet pipe interface 22 and the outlet pipe interface 23 adopt standardized flanges, quick couplings, or socket designs, and with the help of rubber sealing rings, the pipes can be sealed to avoid soil pollution or reduced treatment efficiency caused by wastewater leakage.

[0049] The two-layer three-dimensional sewage treatment system provided in this embodiment is used as follows: When treating domestic sewage, the system proceeds in the following order: equalization tank (optional) → pretreatment → biological treatment (geometric cylinder sewage treatment tank) → advanced treatment → disinfection. Sewage first enters the equalization tank, where the flow rate is balanced by a flow regulating valve and the flow rate is monitored by a flow monitor to prevent load fluctuations in subsequent units. Next, the pretreatment unit removes impurities to prevent equipment blockage. Subsequently, the sewage undergoes biological treatment in the geometric cylinder sewage treatment tank, achieving nitrogen and phosphorus removal, and odor can be recovered from the top of the tank. Afterwards, advanced treatment improves the water quality, and finally, the system is disinfected by a disinfection unit (ultraviolet light or sodium hypochlorite) to ensure that the effluent meets standards.

[0050] Throughout the process, the horizontal layout of the mounting frame shortens the transmission distance, the standardized interfaces and unidirectional pipes prevent leakage and backflow, each module can be inspected and maintained independently, the system occupies little space and is highly efficient, making it suitable for urban land-scarce scenarios.

[0051] Example 2:

[0052] This embodiment provides a two-layer three-dimensional sewage treatment system, which includes all the structures of the two-layer three-dimensional sewage treatment system in Embodiment 1.

[0053] In this embodiment, as Figure 8 As shown, the mounting frame 1 has two layers of support structures from top to bottom, each supporting the corresponding layer of modular wastewater treatment process units 2. By stacking the modular wastewater treatment process units 2 vertically in a two-layer layout, more modular wastewater treatment process units 2 can be accommodated in the same area (e.g., 3 units in a single layer, 6 units in two layers), significantly improving the wastewater treatment capacity per unit area, especially suitable for scenarios with scarce land resources. The modular wastewater treatment process units 2 in the upper and lower layers can be selected to be correspondingly distributed or staggered in the vertical direction. The corresponding distribution can achieve a compact layout, suitable for scenarios with uniform unit size and a pursuit of overall regularity; the staggered distribution (e.g., the upper and lower modular wastewater treatment process units 2 are offset by a certain distance in the horizontal direction) can accommodate combinations of modular wastewater treatment process units 2 of different sizes, avoiding space waste caused by differences in the width of the modular wastewater treatment process units 2, and achieving more flexible matching in a limited three-dimensional space. When it is necessary to replace the modular wastewater treatment process unit 2 with different specifications in the future (such as replacing the original 2m wide modular wastewater treatment process unit 2 with a 3m wide modular wastewater treatment process unit 2), the adjustability of the staggered distribution can avoid the overall structural modification caused by the change in size; while the regularity of the corresponding distribution makes it easy for the system to be expanded in batches according to standardized modules (such as symmetrically adding two new sets of two-layer modular wastewater treatment process units 2). The two distribution modes together improve the system's adaptability to different operating conditions and expansion needs.

[0054] In this embodiment, as Figure 8As shown, the top of the structural column 11 of the mounting frame 1 is equipped with a vertical connecting component, and the end of the structural beam 12 of the mounting frame 1 is reserved with a horizontal connecting component to enable the vertical and horizontal expansion of the mounting frame 1. Specifically, in this embodiment, the vertical connecting component (such as a flange, tenon and mortise structure, high-strength bolt group, etc.) at the top of the structural column 11 can accurately connect to the structural column 11 of the new floor, ensuring the verticality deviation of the upper and lower mounting frames 1 and the uniform load transfer. The horizontal connecting component (such as splicing ear plate, slot-type connector) at the end of the structural beam 12 can enable the mounting frame 1 to extend to both sides or around the perimeter. The new module is quickly fixed to the expansion area through the positioning component 21 and connected to the original system through pipelines. This achieves the long-term development goal of on-demand expansion and dynamic adaptation, providing technical support for the sustainable operation of the sewage treatment plant.

[0055] like Figure 8 As shown, in this embodiment, the mounting frame 1 is a steel structure frame, with each layer of the mounting space equipped with a detachable anti-corrosion load-bearing plate 13, and the mounting frame 1 has an inspection passage 14 and a ladder on its side. The steel structure frame has the characteristics of high strength and good toughness, and compared with traditional concrete structures, it can withstand greater concentrated loads and dynamic loads. The load-bearing plates are made of corrosion-resistant materials (such as galvanized steel plates and fiberglass), and the surface is coated with an anti-corrosion coating (such as epoxy zinc-rich paint and polyurethane paint), which can effectively resist the corrosion of sewage, moisture and chemical agents.

[0056] Example 3:

[0057] like Figure 9 As shown, this embodiment provides a two-layer three-dimensional sewage treatment system, which differs from the two-layer three-dimensional sewage treatment system described in Embodiment 1 in the layout of multiple modular sewage treatment process units 2 and geometric cylinder sewage treatment tank 3.
