Technical Field

[0001] This utility model relates to the field of rural sewage resource utilization technology, and specifically refers to a rural sewage resource utilization facility. Background Technology

[0002] Existing rural wastewater resource utilization facilities generally adopt integrated systems, whose structural materials mainly include steel, fiberglass, plastics, and cast-in-place reinforced concrete. However, all of these materials have significant technical limitations in practical applications: steel structures are prone to corrosion after long-term use, resulting in insufficient durability; while fiberglass structures have excellent corrosion resistance, their manufacturing costs are high, the process is complex, and their impact resistance and temperature resistance are poor, making them prone to aging when exposed to the environment for a long time; plastic structures have the advantages of being lightweight and easy to transport and install, but their low mechanical strength limits their widespread application; cast-in-place reinforced concrete structures suffer from long construction periods, high labor costs, and are greatly affected by climate conditions and temperature changes.

[0003] With the completion of the current rural land registration work, the collective land resources available for development and utilization are becoming increasingly limited, while resources such as ponds, swamps, tidal flats, and rivers are relatively abundant. However, swamps, tidal flats, or ponds without water surfaces generally have high groundwater levels and high silt content; ponds and rivers usually have free water surfaces. All of these present multiple technical challenges to the construction of rural sewage treatment facilities, including high construction difficulty, high structural anti-buoyancy requirements, strict waterproofing requirements, weak foundation bearing capacity, and difficulty in ensuring long-term stable operation.

[0004] Therefore, there is an urgent need for a facility suitable for the resource utilization of rural sewage to fully meet the diverse needs of rural sewage treatment. Utility Model Content

[0005] The purpose of this invention is to provide a facility for the resource utilization of rural sewage in order to solve the problems existing in the prior art.

[0010] The water in adjacent water bodies flows by gravity to the next water body; along the direction of water flow, the first N-1 water bodies contain multiple packing units to create an environment for microbial growth to treat wastewater; the last water body contains the treated wastewater for sedimentation and storage.

[0011] As an improvement to the technical solution of the rural sewage resource utilization facility of this utility model, each of the packing units includes a shell and polyurethane sponge packing filled in the shell.

[0012] As an improvement to the technical solution of the rural sewage resource utilization facility of this utility model, the plurality of said individual modules include a first individual module, a second individual module, a third individual module and a fourth individual module;

[0013] The first single-unit module has a hollow structure, which forms the water-containing space inside;

[0014] The fourth monomer module is disposed on top of the first monomer module, and the filling layer is disposed in the fourth monomer module;

[0015] The second unit module is disposed below the first unit module, and the second unit module is inserted into the special geological formation to support the first unit module and provide anti-buoyancy capability;

[0016] The third single-unit module is disposed on the side of the first single-unit module and the fourth module, and the third single-unit module is inserted into the special geological conditions to support the first single-unit module and enhance the lateral stability of the prefabricated reinforced concrete module.

[0017] As an improvement to the technical solution of the rural sewage resource utilization facility of this utility model, the first single module is a hollow hexahedral or hollow octahedral structure prefabricated with reinforced concrete, with a hollow top and water passage holes with waterproof sleeves on opposite sides for water flow between adjacent single modules; the bottom corner of the first single module is provided with a notch so that the second single module can be nested in the notch.

[0018] The valve body in the middle of the bottom surface of the first single module is in the open state during assembly to allow the mud-water mixture and / or water to enter the first single module to assist in self-sinking. After the first single module stabilizes, the valve body is closed to store sewage or pump out the wastewater.

[0019] As an improvement to the technical solution of the rural sewage resource utilization facility of this utility model, filter components are provided at the outlet and the water passage hole to prevent the filler material filled in the first unit module from entering the next unit module, while the sewage can flow normally.

The second space is connected to the water body holding space through a vent pipe.

[0022] The beneficial effects of this utility model are:

[0023] 1. In this utility model, multiple individual modules are assembled into a prefabricated reinforced concrete module assembly, which forms a space for storing, treating, and utilizing wastewater. Water flows by gravity to transport wastewater to this space for storage. The wastewater and the weight of the multiple individual modules compress the prefabricated reinforced concrete module assembly, ensuring its stability. This allows for the creation of a space for storing, treating, and utilizing wastewater in geological conditions such as high groundwater levels, sludge pools, or free-floating water areas.

[0024] 2. Since at least two water-containing spaces are formed in the prefabricated reinforced concrete modules, filler can be set in the water-containing spaces to carry out hydrolysis and acidification to produce anaerobic reactions, thereby killing mosquito and fly eggs, and then carrying out physical and chemical reactions.

[0025] 3. The multiple individual modules include at least a first individual module, a second individual module, a third individual module, and a fourth individual module.

This design achieves the creation of a space for storing and utilizing wastewater in special geological conditions, overcoming the limitations of high groundwater levels and weak bearing capacity in silty soils, such as areas with high groundwater levels, sludge ponds, or free water surfaces. This design enables the stable installation of the invention in complex and special geological environments such as swamps, ponds, and rivers.

[0026] 4. Due to the modular design of multiple individual modules, it is easy to assemble quickly, shorten the construction cycle, reduce manufacturing costs through optimized design, and improve resource utilization efficiency, thereby maximizing both economic and environmental benefits.

[0027] 5. Since the second and third individual modules serve as pile foundations, this utility model can be installed in special geological conditions. Moreover, this utility model includes multiple individual modules. After the prefabricated reinforced concrete modules are assembled, a filling layer can be formed in the fourth individual module using filling materials such as soil, ceramsite, zeolite, and gravel.

Detailed Implementation

[0038] To make the invention objective, technical solution and beneficial effects of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0039] Example 1

[0040] like Figures 1 to 8 As shown, this utility model provides a rural sewage resource utilization facility, which is set in a special geological environment, namely a geological environment with a high groundwater level, sludge pools, or free water surface areas.

[0041] The rural sewage resource utilization facility includes multiple individual modules and pipelines running between them. The individual modules can be spliced ​​together to build a prefabricated reinforced concrete module assembly. A filling layer 6 is set on the top of the prefabricated reinforced concrete module assembly, and plants 11 are planted in the filling layer 6 to facilitate integration with the local rural environment. At least two interconnected water-containing spaces 7 are formed within the prefabricated reinforced concrete module assembly. The filling layer 6 is used to weigh down the prefabricated reinforced concrete module assembly, and sewage is treated and stored in the water-containing spaces 7. The treated water flows out through the outlet for villagers to use.

[0042] This utility model is applicable to the construction of resource utilization facilities in complex environments, mainly in areas with high groundwater levels, abundant silt, or ponds and rivers containing free water surfaces. It addresses the issue of insufficient land for resource utilization facilities in rural areas after land registration. This utility model adopts a prefabricated design, allowing for batch customization and rapid installation. It boasts advantages such as fast manufacturing speed, large-scale customization, quick on-site construction, convenient installation, and short construction period, solving problems such as slow delivery, long construction periods, and complex installation of existing rural wastewater resource utilization facilities. The top of this utility model is covered with a filling layer 6 of a certain thickness for planting flowers or fragrant plants 11, and can also serve as an educational demonstration base for rural wastewater resource treatment in local schools, addressing the problems of existing rural wastewater resource utilization facilities not integrating with the environment and emitting odors. This utility model is prefabricated with reinforced concrete, offering long service life, high strength, and a price advantage, solving the problems of short service life, low strength, and high cost of existing rural wastewater resource utilization facilities.

[0043] In some embodiments of this utility model, at least two water body accommodating spaces 7 include N water body accommodating spaces 7;

[0044] The water in the adjacent water body holding space 7 flows to the next water body holding space by gravity. Along the water flow direction, the first N-1 water body holding spaces are equipped with multiple packing units to form an environment for microbial growth to treat sewage. The last water body holding space is used for sedimentation and storage of treated sewage. Along the water flow direction, the first N-1 water body holding spaces 7 are equipped with multiple packing units 17 to form an environment for microbial growth to treat sewage. The last water body holding space 7 is used for sedimentation and storage of treated sewage.

[0045] In detail, in this invention, the water flow in at least two water-containing spaces 7 relies on gravity to achieve natural flow of sewage, effectively reducing the use of mechanical power equipment and lowering energy consumption and maintenance costs. The packing material units 17 installed in the first N-1 water-containing spaces 7 provide ample space for microorganisms to attach and grow, forming a stable biological treatment environment. This allows the microorganisms to fully exert their degradation effect on pollutants in the sewage, improving sewage treatment efficiency and purification effect. After multi-stage treatment, the sewage is finally settled and stored in the final water-containing space 7, achieving centralized purification and resource utilization of sewage. This system has a simple structure, stable operation, and is suitable for various sewage treatment scenarios, especially in areas with insufficient power supply or high energy consumption control requirements, combining good economic and environmental benefits.

[0046] The first unit module 1 is designed with filler 17 to construct a specialized microbial treatment area, while the last tank is not filled with filler 17. This avoids the filler 17 from releasing pollutants in this space after adsorbing them in the early stage, which would affect the quality of the effluent. At the same time, it provides sedimentation or temporary storage space for the treated wastewater, optimizing the continuity and stability of the overall treatment process. This solution combines microbial cultivation efficiency with system operation reliability and is suitable for various biological wastewater treatment scenarios.

[0047] Moreover, since the water in the last water storage space 7 has been treated and settled, villagers can export the water in the last water storage unit to the outlet storage well, and use a water pump to extract the treated clean water from the outlet storage well for irrigation of vegetable gardens, woodlands, and landscape plants, as well as to replenish the natural water body.

[0048] Furthermore, if villagers wish to utilize water bodies with higher fertility, they can draw water from the pre-reserved manholes in the front end of the resource utilization facility, specifically in the first N-1 water body storage spaces 7, for irrigating vegetable gardens and woodland landscape plants.

[0049] Furthermore, each filler unit 17 includes a housing and a polyurethane sponge filler 17 filled within the housing.

[0050] As a specific embodiment of this implementation, the packing 17 is... Polyurethane sponge balls, or 2*2*2cm or 3*3*3cm polyurethane sponge filler 17, are used to fill the first single-unit module 1 with a filling rate of 30-66.7%. This provides a suitable environment for microbial growth and also facilitates the rapid accumulation of microorganisms. The last tank is not filled with filler 17.

[0051] Polyurethane sponge balls or 2*2*2cm to 3*3*3cm polyurethane sponge filler 17, with their porous structure and suitable size, can provide sufficient attachment surface and growth space for microorganisms, forming a stable biofilm carrier. Moreover, the filling rate of 30-66.7% can ensure the habitat required for the rapid enrichment and metabolic activities of microorganisms, and can also avoid the increase in water flow resistance or blockage caused by the filler 17 being too dense, thus ensuring efficient contact mass transfer between sewage and microorganisms.

[0052] In some embodiments of this utility model, the multiple individual modules include a first individual module 1, a second individual module 2, a third individual module 3, and a fourth individual module 4.

[0053] The first single-unit module 1 is a hollow structure, which forms a water-containing space 7 inside;

[0054] The fourth unit module 4 is positioned above the first unit module 1, and the filling layer 6 is positioned within the fourth unit module 4;

[0055] The second unit module 2 is disposed below the first unit module 1, and the second unit module 2 is inserted into the special geological conditions to support the first unit module 1 and provide anti-buoyancy capability;

[0056] The third unit module 3 is located on the side of the first unit module 1 and the fourth module, and the third unit module 3 is inserted into the special geological conditions to support the first unit module 1 and enhance the lateral stability of the prefabricated reinforced concrete module.

[0057] As one embodiment of this implementation, the first single-unit module 1 is a hollow hexahedral or hollow octahedral structure prefabricated with reinforced concrete. Its top is hollow, and water passage holes 5 with waterproof sleeves are opened on opposite sides to allow water flow between adjacent single-unit modules. A notch 8 is provided at the corner of the bottom surface of the first single-unit module 1 so that the second single-unit module 2 can be nested in the notch 8; or a cuboid block with a notch 8 is provided at the corner of the bottom surface of the first single-unit module 1 so that the second single-unit module 2 can be nested in the notch 8.

[0058] The valve body 12 in the middle of the bottom surface of the first unit module 1 is in the open state during assembly to allow the mud-water mixture and / or water to enter the first unit module 1 to assist in self-sinking. After the first unit module 1 is stable, the valve body 12 is closed to store sewage or pump out the wastewater.

[0059] In detail, in this utility model, the first precast reinforced concrete module 1 is presented as a hollow hexahedron or octahedron structure, with a hollow top and water passage holes 5 with waterproof sleeves on both sides. This ensures smooth water flow between adjacent modules while effectively preventing leakage and ensuring the system's airtightness. The nesting arrangement of the bottom corner notch 8 of the first module 1 and the second module 2 enhances the stability and anti-overturning ability of the overall structure, facilitating large-scale splicing and construction. Moreover, the valve body 12 in the middle of the bottom surface opens during splicing, allowing the flow of mud-water mixture or water to assist in self-sinking, reducing the need for mechanical hoisting. After the module stabilizes, the valve body 12 closes, which can flexibly realize functions such as sewage storage and vacuuming maintenance. This integrates functions such as pile positioning, storage, and maintenance, shortening the construction cycle, reducing construction difficulty and cost, and improving the system's ease of operation and adaptability. It is suitable for various water conservancy projects and sewage treatment scenarios.

[0060] Preferably, the valve body 12 is a ball valve.

[0061] Furthermore, filter components are installed at the outlet and the water passage 5 to prevent the packing material 17 filled in the first unit module 1 from entering the next unit module, while allowing sewage to flow normally.

[0062] It should be noted that the first unit module 1 has water passage holes 5 on its side wall. Along the water flow direction, the water passage hole 5 in the water inlet direction is the water inlet hole, and the water passage hole 5 in the water outlet direction is the water outlet hole. The water inlet hole is equipped with an inlet pipe, and the water outlet hole is equipped with an outlet pipe. The left end of the outlet pipe is connected to the filter cap 14 with a screen, and the right end is connected to the water inlet pipe of the next first unit module 1.

[0063] As one embodiment of this implementation, the bottoms of the second unit module 2 and the third unit module 3 are both pointed structures for insertion into a special geological formation; and the second unit module 2 and the third unit module 3 are connected to the first unit module 1 and the fourth unit module 4 via connectors.

[0064] Since the second and third individual modules 2 and 3 serve as pile foundations, the present invention can be installed in special geological conditions. Moreover, the present invention includes multiple individual modules. After the prefabricated reinforced concrete modules are assembled, plants 11 can be planted in the filling layer of the fourth individual module 4, and the filling layer can be used as a weight. This can form a rural sewage resource treatment education demonstration base for local schools, solve the problem that existing rural sewage resource utilization facilities cannot be integrated with the environment and emit odors, and generate a synergistic effect of pile foundation, modularization and ecology.

[0065] Since the third single-unit module 3 is fixedly set on the outer side of this utility model, the prefabricated reinforced concrete module assembly can be made to settle and resist buoyancy as a whole through the third single-unit module 3.

[0066] As one embodiment of this implementation, the fourth unit module 4 is rectangular in shape, and a first space 9 connected to the water body containing space 7 is opened in the middle of the fourth unit module 4; along the circumference of the first space 9, a plurality of second spaces 10 are also opened on the fourth unit module 4, and a filling layer 6 is provided in the second space 10. The second space 10 is connected to the water body containing space 7 through a vent pipe 18.

[0067] The top surface of the first space 9 is equipped with a manhole cover 19, which allows staff to enter the first space 9 and the water containment space to inspect or replace the valve body.

[0068] The fourth unit module 4 adopts a cuboid structure and has a reasonable spatial layout; the second space 10 is connected to the water body containing space 7 through a vent pipe 18, wherein the bottom surface of the vent pipe 18 is flush with the bottom surface of the fourth unit module 4, which can exhaust the gas in the first unit module 1.

[0069] In detail, this utility model organically combines multiple functional single-unit modules, with the first single-unit module 1 as the core processing space, the second single-unit module 2 and the third single-unit module 3 constructing a pile foundation support system, and the fourth single-unit module 4 forming an ecological counterweight layer, thus forming a complete technical chain.

[0070] The third unit module 3 is connected to the first unit module 1 and the fourth unit module 4 via screws 15. The screws 15, with nuts at both ends, lock the connection points of the two first unit modules 1 respectively, and lock the outermost first unit module 1 to the third unit module 3. A screw hole 13 is provided in the third unit module 3, through which the screws 15 pass to achieve the locking effect.

[0071] After the prefabricated reinforced concrete modules are tightened by locking with screws 15 and splicing with notches 8, the fourth unit module 4 is filled with soil, gravel and other materials to form a filling layer 6. At the same time, the filling layer can also serve as a weight to further enhance the stability of the overall structure in special geological conditions. Meanwhile, local ornamental plants 11 are planted in the filling layer 6, which organically combines the engineering support function of the pile foundation, the rapid assembly advantage of the modular design and the environmental integration requirements of ecological planting. Not only does the root system of the plants 11 help stabilize the facilities, but the vegetation cover also beautifies the rural landscape and absorbs odors, forming a synergistic effect of "engineering support - rapid construction - ecological restoration", ultimately achieving the dual goals of rural sewage treatment and ecological protection in complex environments.

[0072] Moreover, this utility model meets the following requirements: First, it is convenient for on-site installation, requiring modular design of facility components to facilitate rapid assembly and shorten the construction cycle; second, it has good corrosion resistance to ensure long-term stable operation of the facility under harsh geological conditions; third, it has good cost-effectiveness, reducing manufacturing costs through optimized design while improving resource utilization efficiency to maximize both economic and environmental benefits; and fourth, it has high adaptability, requiring the facility to be able to flexibly cope with areas with high groundwater levels, silty geology, or free water surfaces, ensuring stable sewage treatment function in complex environments and fully meeting the diverse needs of rural sewage treatment.

[0073] This utility model discloses a method for constructing and using a rural wastewater resource utilization facility. The construction and use of the aforementioned rural wastewater resource utilization facility includes the following steps:

[0074] The second single-unit module 2 is pressed into a special geological formation by external forces;

[0075] The first single-unit module 1 is hoisted and moved to the top surface of the second single-unit module 2, so that the first single-unit module 1 and the second single-unit module 2 are relatively fixed. The second single-unit module 2 acts as a pile support for the first single-unit module 1, providing structural support and anti-buoyancy capability.

[0076] The third unit module 3 is fixed to the outside of at least two first unit modules 1 to provide support and lateral stability for the first unit module 1 and the fourth unit module 4.

[0077] The fourth unit module 4 is hoisted and moved onto the first unit module 1 to weigh down the prefabricated reinforced concrete module assembly body;

[0078] Wastewater enters the water-containing space 7 in the prefabricated reinforced concrete module assembly, where it is stored and treated.

[0079] The water flows by gravity to the next water body holding space 7, which is equipped with a packing unit 17 to treat sewage.

[0080] A filling layer 6 is provided in the fourth single module 4, and plants 11 are planted in the filling layer 6 to facilitate integration with the local rural environment. At least two interconnected water-containing spaces 7 are formed in the first single module 1 of the prefabricated reinforced concrete module assembly. The filling layer 6 is used to weigh down the prefabricated reinforced concrete module assembly, and sewage is treated and stored in the water-containing spaces 7.

[0081] Furthermore, pipes are used to connect the water passage holes 5 at the connection points of every two adjacent first unit modules 1, and waterproofing treatment is applied.

[0082] In detail, as a specific embodiment of this utility model, the effluent from the septic tanks of each rural household is collected to the inspection well at the end of the sewage pipe network, and then the effluent is pretreated by being connected to a grit well. The well can be constructed of stainless steel grit mesh with a spacing of 3-6mm.

[0083] The pretreated wastewater is fed into the water-containing space 7 of this invention for hydrolysis, acidification, and anaerobic reaction, thereby killing mosquito and fly eggs, and then undergoing physical and chemical reactions.

[0084] Wastewater treated by the resource utilization facility enters the effluent storage well, where it is then either utilized for resource recovery or discharged.

[0085] The system includes a water pump installed at the outlet storage well, allowing villagers to use the treated water for irrigation of vegetable gardens and woodlands, as well as to replenish natural water bodies. Alternatively, to obtain water with higher fertility, villagers can draw water from the resource utilization facility via a pre-installed manhole for irrigation of their vegetable gardens and woodlands.
