Description

Technical Field

[0001] This invention relates to the field of constructed wetland technology, and more particularly to a modular constructed wetland for rural sewage treatment. Background Technology

[0002] Constructed wetlands are artificially built and controlled wetland-like areas where wastewater and sludge are systematically distributed. As the wastewater and sludge flow in a specific direction, the technology utilizes the synergistic physical, chemical, and biological processes of soil, artificial media, plants, and microorganisms to treat them. Its mechanisms include adsorption, retention, filtration, oxidation-reduction, sedimentation, microbial decomposition, transformation, plant shading, residue accumulation, transpiration of water and nutrients, and the activity of various animals. Currently, constructed wetlands simply distribute substrate and vegetation in patches without zoning or management. Foreign matter in the wastewater floats around due to water flow, making regular cleaning difficult.

[0003] A search revealed Chinese patent application CN202122838030.8, which discloses an artificial wetland system relating to the field of artificial wetland technology. This system includes vertical flow artificial wetlands and horizontal flow artificial wetlands. The vertical flow artificial wetland comprises an upward vertical subsurface flow area and a downward vertical subsurface flow area, with their upper ends interconnected. Emergent plants are planted in both the upward and downward vertical subsurface flow areas, while submerged plants are planted in the horizontal flow artificial wetland. The artificial wetland system in this patent has the following shortcomings: it lacks regional management of the artificial wetland, and foreign matter in the wastewater floats in various locations due to water flow, making regular cleaning difficult. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a modular artificial wetland for rural sewage treatment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A modular constructed wetland for rural wastewater treatment includes:

[0007] The modular assembly consists of multiple modules connected by connecting components. The modular assembly has a "U"-shaped structure. A second filter port is provided on the outside of the modular assembly, and a packing layer is provided on the inside of the modular assembly.

[0008] The partition has an annular structure adapted to the size of the modular assembly. The partition includes a first partition plate and a second partition plate. The second partition plate is located on top of the first partition plate and extends outward in a vertically upward direction. The first and second partition plates have openings. An annular cavity is formed between the partition and the modular assembly, and the annular cavity is filled with filter material. The filter material can be activated carbon, sand, etc.

[0009] The connection component includes:

[0010] The collection tank has a first mounting rod at the bottom and a first mounting hole adapted to the first mounting rod at the top of the modular unit. The first mounting rod is inserted into the first mounting hole. First filter ports are provided on both sides of the collection tank.

[0011] Preferably, a top cover is detachably installed on the top of the collection tank, a second mounting rod is provided at the bottom of the top cover, a mounting plate is fixed on the top of the collection tank, a second mounting hole is opened on the mounting plate, the top cover is installed in the second mounting hole through the second mounting rod, the top of the top cover has an arc surface structure, and the top of the top cover has evenly distributed collection ports, the inner diameter of the collection ports gradually increases in the vertical upward direction.

[0012] Furthermore: a limiting plate is provided on the inner side of the bottom of the top cover. The limiting plate includes a first limiting plate body and a second limiting plate body with an annular structure. The second limiting plate body is disposed inside the first limiting plate body. The first limiting plate body is fixed to the inner side of the bottom of the top cover. The second limiting plate body is inclined downward towards the center.

[0017] Based on the aforementioned scheme: multiple airbag floats are fixed on the outer walls of both sides of the collection tank, and the first mounting rod is slidably connected to the first mounting hole.

[0018] A preferred embodiment of the aforementioned scheme is as follows: the first mounting rod is slidably mounted in the first mounting hole, and a first annular rubber ring is fixed to the outer wall of the bottom end of the first mounting rod.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. This invention, by setting up modular components and collection troughs, enables modular assembly based on the modular components and allows for the regional division of constructed wetlands, which is beneficial for management.

The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain this patent and should not be construed as a limitation of this patent.

[0034] Embodiment 1:

[0035] An assembled artificial wetland for rural sewage treatment, as Figure 1-6 shown, includes:

[0036] An assembled module 1, multiple assembled modules 1 are spliced and connected through a connection component. The assembled module 1 has a "mouth" - shaped structure. A second filter port 11 is provided on the outer side of the assembled module 1, a packing layer 14 is provided on the inner side of the assembled module 1. The packing layer may be laid with a water - permeable matrix for traditional artificial wetlands, and aerobic and anaerobic microbial populations should be cultivated below the matrix. Aquatic plants are planted in the assembled module 1;

[0037] A partition 15, the partition 15 has an annular structure adapted to the size of the assembled module 1. The partition 15 includes a first partition plate body 20 and a second partition plate body 17. The second partition plate body 17 is integrally provided on the top of the first partition plate body 20, and the second partition plate body 17 extends outward in the vertically upward direction. Through ports 16 are formed on the first partition plate body 20 and the second partition plate body 17. An annular cavity 13 is formed between the partition 15 and the assembled module 1, and the annular cavity 13 is filled with a filtering material; the filtering material can be activated carbon, sand, etc.;

[0038] Among them, the connection component includes:

[0039] The collection tank 6 has a first mounting rod 23 integrally provided at the bottom. The top of the modular module 1 has a first mounting hole 10 that is adapted to the first mounting rod 23. The first mounting rod 23 is inserted into the first mounting hole 10. The collection tank 6 has a first filter port 27 on both sides.

[0040] By setting up structures such as modular module 1 and collection tank 6, modular splicing can be achieved based on modular module 1, and regional division of artificial wetlands can be realized, which is conducive to management. In addition, collection tank 6 not only serves to connect modular module 1, but also collects impurities in the water, which is conducive to subsequent dredging and cleaning, thus improving practicality.

[0041] To facilitate the collection of impurities and prevent them from escaping from the collection tank 6; such as Figure 5 As shown, a top cover 2 is detachably installed on the top of the collection tank 6. A second mounting rod 25 is integrally provided at the bottom of the top cover 2. A mounting plate 22 is fixed on the top of the collection tank 6. A second mounting hole 21 is provided on the mounting plate 22. The top cover 2 is installed in the second mounting hole 21 through the second mounting rod 25. The top of the top cover 2 has an arc-shaped structure. The top of the top cover 2 has evenly distributed collection ports 9. The inner diameter of the collection ports 9 gradually increases in the vertical upward direction.

[0042] By setting up structures such as the top cover 2, since the top of the top cover 2 is an arc-shaped structure, it can play a guiding role, and impurities enter the collection tank 6 through the collection port 9, thus achieving the purpose of collection.

[0043] To prevent impurities from escaping from collection tank 6; such as Figure 3 , Figure 5 , Figure 6 As shown, a limiting plate 12 is integrally provided on the inner side of the bottom of the top cover 2. The limiting plate 12 includes a first limiting plate body 19 and a second limiting plate body 18 with an annular structure. The second limiting plate body 18 is integrally provided on the inner side of the first limiting plate body 19. The first limiting plate body 19 is fixed to the inner side of the bottom of the top cover 2. The second limiting plate body 18 is inclined downward towards the center.

[0044] By setting the first limiting plate 19 and the second limiting plate 18, when impurities enter the top cover 2, they can be guided to enter the collection tank 6. The inclined second limiting plate 18 can block the impurities in the collection tank 6, thus improving practicality.

[0045] To improve reliability; such as Figure 6 As shown, a second annular rubber ring 26 is fixed to the outside of the second mounting rod 25;

[0046] By setting the second mounting rod 25, the second mounting rod 25 can be pulled out by applying external force under the deformation of the second annular rubber ring 26 during disassembly, thus improving practicality.

[0047] like Figure 1 As shown, a module gap 5 is formed between two adjacent assembled modules 1, and a filter layer is filled in the module gap 5; the filter layer can adopt the same structure as the filler layer 14.

[0048] To improve reliability; such as Figure 3 , Figure 4 As shown, an inner support 3 is installed on the inner side of the modular module 1, and an array of grids is provided on the inner support 3 for aquatic plants to pass through.

[0049] To facilitate the drainage of water; such as Figure 1 As shown, a water chamber 8 is provided on the outside of the modular module 1. The water chamber 8 is connected to the annular cavity 13 through the second filter port 11. A discharge pipe 7 is provided on one side of the water chamber 8.

[0050] By setting up water chamber 8, the filtered water can be collected and guided for easy discharge.

[0051] In this embodiment, modular splicing can be achieved based on the assembled module 1, which is conducive to the regional division of the constructed wetland and convenient management. In addition, the collection tank 6 not only serves to connect the assembled module 1, but also collects impurities in the water, which is conducive to subsequent dredging and cleaning, thus improving practicality.

[0052] In use, the top of the top cover 2 has an arc-shaped structure, which can act as a guide. Impurities enter the collection tank 6 through the collection port 9 to achieve the purpose of collection. The first limiting plate 19 and the second limiting plate 18 can guide the impurities into the collection tank 6 when they enter the top cover 2. The inclined second limiting plate 18 can block the impurities in the collection tank 6, thus improving practicality.

[0053] Example 2:

[0054] A modular constructed wetland for rural wastewater treatment, such as Figure 6 As shown, in order to better collect floating impurities, this embodiment makes the following improvements based on embodiment 1: multiple airbag floats 4 are fixed on the outer walls of both sides of the collection tank 6, and the first mounting rod 23 is slidably connected to the first mounting hole 10;

[0055] By setting the airbag float 4, the height of the collection tank 6 can be kept near the liquid surface, thereby better collecting floating objects and making it easier to clean.

[0056] To prevent the first mounting rod 23 from dislodging from the first mounting hole 10; as follows: Figure 6 As shown, the first mounting rod 23 is slidably mounted in the first mounting hole 10, and a first annular rubber ring 24 is fixed on the outer wall of the bottom end of the first mounting rod 23.

[0057] By setting up structures such as the first annular rubber ring 24, the collection groove 6 can be limited to a certain extent, preventing the first mounting rod 23 from dislodging from the first mounting hole 10.

[0058] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
