Description

Technical Field

[0001] This invention relates to the field of constructed wetland wastewater treatment technology, and more specifically, to a constructed wetland water distribution system. Background Technology

[0002] Constructed wetlands effectively remove various pollutants from polluted water bodies and are simple to operate and manage with low construction costs, thus finding widespread application in domestic wastewater treatment. During operation, uniform water distribution ensures that each area receives adequate moisture and pollutants, thereby improving the overall purification efficiency. Uniform water distribution reduces damage to the wetland substrate caused by localized overload and alternating wet and dry conditions, extending the wetland's lifespan. Uneven water distribution, on the other hand, may result in insufficient water in some areas, leading to inadequate wastewater treatment and reduced purification efficiency. Uneven water distribution can also cause the substrate to become saturated too quickly in some areas, accelerating substrate degradation and clogging, and affecting the long-term operation of the wetland.

[0003] Existing constructed wetland water distribution technology mainly uses perforated water distribution. However, as the wetland operates, the water distribution pipes and substrate are prone to clogging, affecting the uniformity of water distribution and reducing the wetland treatment efficiency. Many wetlands experience clogging problems, resulting in uneven water distribution. Summary of the Invention

[0025] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0026] The artificial wetland water distribution system of this invention includes: a third water-guiding rope 4, a soil layer 6, a water-diverting component (not shown), a first layer 1, a second layer 2, and a water-guiding support pipe 3. The first layer 1 and the second layer 2 are arranged at intervals in the vertical direction. The inlet of the water-guiding support pipe 3 is connected to the first layer 1, and the outlet of the water-guiding support pipe 3 is connected to the second layer 2. Both the first layer 1 and the second layer 2 include a water-guiding pad component 21, multiple first water-guiding ropes 22, and multiple second water-guiding ropes 23. The extension direction of the first water-guiding ropes 22 is orthogonal to the extension direction of the second water-guiding ropes 23. The first water-guiding ropes 22 and the second water-guiding ropes 23 are connected. The water-guiding pad component 21 is sleeved on the connection between the first water-guiding ropes 22 and the second water-guiding ropes 23. Both the first water-guiding ropes 22 and the second water-guiding ropes 23 are connected to the water-guiding pad component 21. The first layer 1 also includes multiple first horizontal pipes 1. 1. A plurality of first longitudinal pipes 12, a first upper support plate 14 and a first lower support plate 15, the axial direction of the first horizontal pipe 11 is orthogonal to the axial direction of the first longitudinal pipe 12, the first horizontal pipe 11 and the first longitudinal pipe 12 are connected and pass through each other, the first upper support plate 14 and the first lower support plate 15 are disposed at the connection between the first horizontal pipe 11 and the first longitudinal pipe 12, the first upper support plate 14 is connected to the upper end of the first horizontal pipe 11 and the first longitudinal pipe 12, the first lower support plate 15 is connected to the lower end of the first horizontal pipe 11 and the first longitudinal pipe 12, a water guiding pad component 21 is disposed between the first upper support plate 14 and the first lower support plate 15, a first water guiding rope 22 is disposed in the first horizontal pipe 11, and a second water guiding rope 23 is disposed in the first longitudinal pipe 12, or, the first water guiding rope 22 is disposed in the first longitudinal pipe 12, and the second water guiding rope 23 is disposed in the first horizontal pipe 11. The third water guide rope 4 is arranged inside the water guide support pipe 3. One end of the third water guide rope 4 is connected to either the first water guide rope 22 or the second water guide rope 23 of the first layer 1, and the other end of the third water guide rope 4 is connected to either the first water guide rope 22 or the second water guide rope 23 of the second layer 2. One end of the water diversion component is connected to either the first horizontal pipe 11 or the first vertical pipe 12, and the other end of the water diversion component is connected to the water source. Both the first layer 1 and the second layer 2 are set within the soil layer 6, and the first layer 1 is set above the second layer 2.

[0027] Specifically, such as Figures 1 to 6 As shown, the first layer 1 and the second layer 2 are arranged at intervals in the vertical direction. Both the first layer 1 and the second layer 2 include a first water guide rope 22, a second water guide rope 23 and a water guide pad component 21. The water guide pad component 21 is located at the connection between the first water guide rope 22 and the second water guide rope 23, or the water guide pad component 21 is located near the connection between the first water guide rope 22 and the second water guide rope 23 and is connected to at least one of the first water guide rope 22 and the second water guide rope 23 in order to receive the water output by the first water guide rope 22 and the second water guide rope 23.

[0028] The first water-guiding rope 22 and the second water-guiding rope 23 are arranged orthogonally to form the water supply structure of the first layer 1. The first layer 1 is also equipped with a support structure to protect the water-guiding ropes of the first layer 1. Since the first layer 1 is relatively shallow in the soil layer 6, plant roots and stems may affect or damage the shallow first water-guiding rope 22 and the second water-guiding rope 23. By setting the first water-guiding rope 22 to be arranged in the first horizontal pipe 11 and the second water-guiding rope 23 to be arranged in the first vertical pipe 12, or the first water-guiding rope 22 to be arranged in the first vertical pipe 12 and the second water-guiding rope 23 to be arranged in the first horizontal pipe 11, the stability and safety of water delivery are improved, and water delivery does not require perforation of the guide pipe, avoiding the blockage that is easily caused by using guide pipes.

[0029] It should be noted that the first water guide rope 22 and the second water guide rope 23 are orthogonal, and the first horizontal pipe 11 and the first vertical pipe 12 are orthogonal. The first water guide rope 22 can be arranged inside the first horizontal pipe 11 and the second water guide rope 23 can be arranged inside the first vertical pipe 12, or the first water guide rope 22 can be arranged inside the first vertical pipe 12 and the second water guide rope 23 can be arranged inside the first horizontal pipe 11. For ease of description, in this application, the first water guide rope 22 is arranged inside the first horizontal pipe 11, and the first horizontal pipe 11 and the first water guide rope 22 extend in the left-right direction. The second water guide rope 23 is arranged inside the first vertical pipe 12, and the second water guide rope 23 and the first vertical pipe 12 extend in the front-back direction.

[0030] The first upper support plate 14 is disposed at the upper end of the first horizontal pipe 11 and the first vertical pipe 12 and is connected to the first horizontal pipe 11 and the first vertical pipe 12. The first lower support plate 15 is disposed at the lower end of the first horizontal pipe 11 and the first vertical pipe 12 and is connected to the first horizontal pipe 11 and the first vertical pipe 12. The first upper support plate 14 and the first lower support plate 15 are arranged at intervals in the vertical direction. The water guiding pad component 21 of the first layer 1 is disposed between the first upper support plate 14 and the first lower support plate 15 to support the water guiding pad. At the same time, the first vertical pipe 12 and the first horizontal pipe 11 also support the water guiding pad component 21.

[0031] The artificial wetland water distribution system of this invention, through the arrangement of a first horizontal pipe 11, a first vertical pipe 12, a first upper support plate 14, and a first lower support plate 15, guides water through a first water-guiding rope 22 and a second water-guiding rope 23. This results in a more stable water distribution structure and more uniform water distribution, eliminating the clogging problem associated with perforated pipe water distribution in related technologies. The first horizontal pipe 11 and the first vertical pipe 12 support and protect the first water-guiding rope 22 and the second water-guiding rope 23. The first upper support plate 14 and the first lower support plate 15 support and protect the water-guiding pad component 21. The first horizontal pipe 11 and the first vertical pipe 12 support and protect the water-guiding structure on the horizontal plane, while the first upper support plate 14 and the first lower support plate 15 support and protect the water-guiding structure in the vertical direction (i.e., the direction of gravity), forming a stable three-dimensional protection and support structure. This ensures uniform water distribution, reduces wetland substrate clogging and the generation of dead water zones, extends the wetland's service life, and improves its purification effect. The first water-guiding rope 22, the second water-guiding rope 23, and the water-guiding pad component 21 have excellent water conduction, absorption, and retention properties, increasing the effective contact time and contact area between the substrate and wastewater, creating a more stable environment for microbial growth, thereby improving the ecological environment of the wetland. Simultaneously, the three-dimensional mesh water distribution system ensures that each area in the substrate receives adequate moisture and pollutants, thus improving the overall purification efficiency of the wetland. The three-dimensional mesh water distribution system divides the wetland into multiple water distribution zones, resulting in a more stable water distribution structure, more uniform water distribution, and no clogging problems, thus overcoming the technical drawbacks of traditional perforated pipe water distribution.

[0032] In some embodiments, a plurality of first horizontal tubes 11 are arranged parallel to each other and spaced apart, a plurality of first vertical tubes 12 are arranged parallel to each other and spaced apart, a plurality of first water guide ropes 22 are arranged parallel to each other and spaced apart, and a plurality of second water guide ropes 23 are arranged parallel to each other and spaced apart.

[0033] Specifically, such as Figures 1 to 6 As shown, for ease of description, in this application, the first water guide rope 22 is arranged inside the first horizontal pipe 11, and the first horizontal pipe 11 and the first water guide rope 22 extend in the left-right direction. The second water guide rope 23 is arranged inside the first vertical pipe 12, and the second water guide rope 23 and the first vertical pipe 12 extend in the front-back direction.

[0034] Multiple first water-guiding ropes 22 are arranged in parallel in the front-to-back direction, multiple second water-guiding ropes 23 are arranged in parallel in the left-to-right direction, multiple first horizontal pipes 11 are arranged in parallel in the front-to-back direction, and multiple first vertical pipes 12 are arranged in parallel in the left-to-right direction to form a uniform water-guiding structure.

[0035] In some embodiments, the second layer 2 further includes a plurality of second horizontal tubes 27, a plurality of second vertical tubes 24, a second upper support plate 25 and a second lower support plate 26. The axial direction of the second horizontal tubes 27 is orthogonal to the axial direction of the second horizontal tubes 27. The second horizontal tubes 27 and the second vertical tubes 24 pass through and communicate with each other. The second upper support plate 25 is connected to the upper ends of the second horizontal tubes 27 and the second vertical tubes 24. The second lower support plate 26 is connected to the lower ends of the second horizontal tubes 27 and the second vertical tubes 24. The water guiding pad component 21 of the second layer 2 is disposed between the second upper support plate 25 and the second lower support plate 26.

[0036] Specifically, such as Figures 1 to 6 As shown, the second horizontal pipe 27 and the second vertical pipe 24 are arranged orthogonally. The second horizontal pipe 27 extends in the front-to-back direction, and the second vertical pipe 24 extends in the left-to-right direction; alternatively, the second horizontal pipe 27 extends in the left-to-right direction, and the second vertical pipe 24 extends in the front-to-back direction. For ease of description, in this application, the second water-guiding rope 23 is arranged inside the second horizontal pipe 27, with both the second horizontal pipe 27 and the second water-guiding rope 23 extending in the left-to-right direction. The second water-guiding rope 23 is also arranged inside the second vertical pipe 24, with both the second water-guiding rope 23 and the second vertical pipe 24 extending in the front-to-back direction. Multiple first horizontal pipes 11 are arranged parallel in the front-to-back direction, and multiple first vertical pipes 12 are arranged parallel in the left-to-right direction to form a uniform water-guiding structure.

[0037] At the same time, a second upper support plate 25 and a second lower support plate 26 are set to support and protect the water guiding pad component 21 of the second layer 2, so as to prevent the water guiding pad component 21 from deforming and blocking under the pressure of the soil layer 6, thereby improving the stability of water guiding and preventing local or individual water guiding pad components 21 from being deformed and blocked under the pressure of the soil layer 6.

[0038] Furthermore, the water-guiding pad component 21 includes an absorbent cotton pad 212 and a buckle 211. The buckle 211 is adapted to fix the first layer 1 absorbent cotton pad 212 on the first upper support plate 14 and the first lower support plate 15 of the first layer 1, and to fix the second layer 2 absorbent cotton pad 212 on the second upper support plate 25 and the second lower support plate 26 of the second layer 2.

[0039] In some embodiments, the first longitudinal tube 12 and the first transverse tube 11 are each provided with a first hole, the first hole facing the water guide pad component 21, and / or the second longitudinal tube 24 and the second transverse tube 27 are each provided with a second hole, the second hole facing the water guide pad component 21.

[0040] Specifically, such as Figures 1 to 6As shown, by setting the first hole, water can be output more smoothly from the first longitudinal pipe 12 and the first horizontal pipe 11 of the first layer 1 to the water guide pad component 21 of the first layer 1. By setting the second hole, water can be output more smoothly from the second longitudinal pipe 24 and the second horizontal pipe 27 of the second layer 2 to the second water guide pad component 21. This reduces the pressure and resistance of the water flow in the pipe and lowers the risk of blockage.

[0041] Both the first layer 1 and the second layer 2 use orthogonally arranged pipes, and holes are set on the pipes to allow water to flow out, so that the water flow can be output to the water guide pad component 21, thereby improving the efficiency and uniformity of water distribution and thus improving the purification effect of the system.

[0042] Furthermore, there are multiple second layers 2, which are arranged at intervals in the vertical direction and positioned away from the ground. The second layers 2 can be equipped with second horizontal pipes 27 and second vertical pipes 24 for support and protection of the water-guiding structure. The multiple second layers 2 arranged in the vertical direction form a multi-layered water supply structure to optimize the water flow path, reduce the time it takes for water to reach the plants in the wetland, and improve the water circulation efficiency.

[0043] In some embodiments, the spacing between the multiple second layers 2 in the vertical direction is 100cm-150cm. This better adapts to the treatment needs at different depths in the wetland system, ensuring that different soil layers 6 within the system can receive water and participate in the wastewater treatment process, preventing the formation of stagnant water zones, thereby extending the lifespan of the wetland and improving purification efficiency.

[0044] Furthermore, the spacing between the multiple first water-guiding ropes 22 ranges from 30cm to 50cm. This ensures that the water-guiding pad component 21 can promptly deliver water to the preset range, preventing the formation of stagnant water zones and thus extending the service life of the wetland.

[0045] In some embodiments, both the first layer 1 and the second layer 2 include a bioelectrode 5, which is disposed on any one of the water-guiding pad component 21, the plurality of first water-guiding ropes 22 and the plurality of second water-guiding ropes 23, and / or the bioelectrode 5 is arranged at intervals from the water-guiding pad component 21, the plurality of first water-guiding ropes 22 and the plurality of second water-guiding ropes 23.

[0046] Specifically, such as Figures 1 to 6 As shown, the bioelectrode 5 can be disposed on any one of the water-guiding pad component 21, the plurality of first water-guiding ropes 22 and the plurality of second water-guiding ropes 23, or the bioelectrode 5 can be arranged at intervals with the water-guiding pad component 21, the plurality of first water-guiding ropes 22 and the plurality of second water-guiding ropes 23.

[0047] When the bioelectrode 5 can be placed on the water-conducting pad component 21, the water-conducting pad component 21 includes an absorbent cotton pad 212. The absorbent cotton pad 212 can be an existing sponge or a water-conducting sponge sleeve. The cotton pad has good water conduction, water absorption and water retention properties, which increases the effective contact time and contact area between the substrate and sewage, making the microbial growth environment more stable, thereby improving the ecological environment of the wetland.

[0048] Bioelectrode 5 can improve the microbial environment of plant roots, enhance the oxygen secretion capacity of plant roots, promote the degradation and transformation of pollutants, and thus improve the purification effect of wetlands.

[0049] In some embodiments, the radial dimensions of the first water-guiding rope 22, the second water-guiding rope 23, and the third water-guiding rope 4 are 4 mm to 10 mm.

[0050] Specifically, such as Figures 1 to 6 As shown, the first water guide rope 22, the second water guide rope 23 and the third water guide rope 4 can be existing water guide ropes with a radial dimension of 4mm to 10mm. This ensures that while supplying and guiding water, the water guide ropes can reduce the risk of blockage caused by physical pressure, thereby improving the stability and service life of the system.

[0051] For example, in the relatively soft soil layer 6, a water-conducting rope with a radial dimension of 4mm can be used, while in the relatively hard soil layer 6, a water-conducting rope with a diameter of 10mm can be used.

[0052] In some embodiments, the water intake component includes a water intake pipe and a filter, one end of the filter is connected to a water source, the other end of the filter is connected to the inlet of the water intake pipe, and the outlet of the water intake pipe is connected to the first layer 1.

[0053] Specifically, such as Figures 1 to 6 As shown, the filter is suitable for filtering water from a water source and then outputting the water into a water inlet pipe to prevent impurities from entering the water inlet pipe or the first layer 1 or the second layer 2, thereby improving the stability of the water supply and the service life of the system.
