Description

An artificial wetland ecological purification system Technical Field

[0001] This application relates to the field of constructed wetland systems, and more particularly to an constructed wetland ecological purification system. Background Technology

[0002] Constructed wetland wastewater treatment technology is a wastewater treatment and water environment restoration technology developed in the late 1970s. It is based on ecological principles and imitates natural ecosystems by artificially combining materials such as soil, sand, and stones in a certain proportion to form a substrate, planting selected pollution-resistant plants, and cultivating a variety of microorganisms to form a new type of wastewater purification system similar to natural wetlands.

[0003] A typical constructed wetland purification system includes, from top to bottom, a planting layer, a filter media layer, and a pebble layer. It also includes permeable pipes located beneath the pebble layer and a ground-level collection tank. The permeable pipes have multiple upward-facing openings and are covered with geotextile fabric, which in turn covers the openings. The permeable pipes connect to the collection tank, which contains a water supply pipe and a sludge discharge pipe. The water supply pipe is equipped with a pump located within the collection tank. The sludge discharge pipe is used to discharge sludge from the bottom of the collection tank and is equipped with a control valve. In operation, rainwater passes through the planting layer, filter media layer, and pebble layer in sequence before entering the permeable pipes and finally collecting in the collection tank. The water in the collection tank can then be pumped out through the water supply pipe to provide a water source for cities, gardens, or other areas. The sludge in the collection tank can be discharged through the sludge discharge pipe to ensure the effective water collection.

[0004] However, in actual use, the water supply pump in the collection tank is usually installed below the collection tank. As the usage time increases, the height of the sludge accumulation at the bottom of the collection tank will gradually increase, which may cover the water supply pump and cause blockage of the water pump. Therefore, when there is an urgent need for external water supply (such as in case of fire), if the sludge is removed first, it may lead to a situation where the external water supply is not timely, which may cause serious consequences. Summary of the Invention

[0005] In order to reduce the possibility of blockage in the water supply pump and improve the performance of the water supply pump, this application provides an artificial wetland ecological purification system.

[0006] The artificial wetland ecological purification system provided in this application adopts the following technical solution:

[0007] An artificial wetland ecological purification system includes, from top to bottom, a planting layer, a filter media layer, and a pebble layer. It also includes a permeable pipe located below the pebble layer and a water collection tank located on the ground. The permeable pipe has multiple upward-facing through-holes and is covered with geotextile fabric covering the through-holes. The permeable pipe is connected to the water collection tank, which is connected to a water supply pipe and a sludge discharge pipe. The water supply pipe is equipped with a water supply pump located within the water collection tank. A lifting assembly is installed within the water collection tank. The lifting assembly includes a mounting plate and an adjusting screw. The adjusting screw is vertically inserted and rotatably connected to the water collection tank. The mounting plate is fitted onto and threadedly connected to the adjusting screw. The water supply pump is mounted on the mounting plate.

[0008] By adopting the above technical solution, rainwater on the ground can be filtered sequentially through the planting layer, filter media layer, and pebble layer, and finally collect in the water collection tank. Then, the water in the water collection tank can be pumped out through the water supply pipe and water supply pump, thus facilitating the supply of water to cities, gardens, or other areas. In case of emergency, if the water supply pump is covered due to long-term sludge accumulation, the adjusting screw can be rotated to pull the mounting plate and water supply pump up, thereby moving the water supply pump away from the sludge, reducing the possibility of blockage during water pumping, and ensuring the normal use of the water supply pump so that the water supply pipe can output water in a timely manner, improving the performance of the water supply pump.

[0009] Optionally, telescopic sleeves are provided above and below the mounting plate. The telescopic sleeves are fitted onto the adjusting screw. One end of the telescopic sleeve is fixedly connected to the mounting plate, and the other end is fixedly connected to the top or bottom wall of the water collection tank.

[0010] By adopting the above technical solution, during use, when adjusting the screw to control the lifting and lowering of the mounting plate, the mounting plate can push the telescopic sleeve to extend and retract. At this time, the telescopic sleeve can reduce the possibility of stirring the water in the collection tank due to the rotation of the adjusting screw, thereby reducing the possibility of stirring the sludge upward, and further reducing the possibility of clogging the water supply pump.

[0011] Optionally, the telescopic sleeve includes multiple sleeve units distributed along the axial direction, wherein the sleeve units are sleeved and slidably connected to adjacent sleeve units, and the sleeve units are configured as prism-shaped structures.

[0012] By adopting the above technical solution, the telescopic sleeve can not only isolate the adjusting screw, but also restrict the rotation of the mounting plate, making the adjusting screw more stable when controlling the sliding of the mounting plate.

[0013] Optionally, the sleeve unit is formed with a scraper, and the scraper is sleeved on an adjacent sleeve unit.

[0014] By adopting the above technical solution, when two adjacent sleeve units slide relative to each other, the scraper can first clean the surface of the adjacent sleeve units, making it more convenient for the two adjacent sleeve units to retract, while reducing the possibility of damage to the connection between the two adjacent sleeve units.

[0015] Optionally, a connecting rod is fixedly connected to the inner wall of the sleeve unit, and a connecting sleeve is fixedly connected to the connecting rod. The connecting sleeve is fitted onto and slidably connected to the adjusting screw.

[0016] By adopting the above technical solution, the combined action of the connecting rod and the connecting sleeve can support the sliding of the sleeve unit, thereby increasing the overall stability of the telescopic sleeve and improving the performance. At the same time, when two adjacent sleeve units retract, the sleeve unit can abut against the connecting rod in the adjacent sleeve unit, thereby limiting the sliding amount of the sleeve unit and making the retraction effect better.

[0017] Optionally, the sleeve unit has a slot for engaging the connecting rod in an adjacent sleeve unit.

[0018] By adopting the above technical solution, when two adjacent sleeve units are contracted, the slot can engage with the connecting rod, thereby improving the integrity between the two adjacent sleeve units.

[0019] Optionally, the mounting plate has ventilation holes that connect the interiors of the two telescopic sleeves. One of the telescopic sleeves has a ventilation pipe inside, and the other end of the ventilation pipe extends to the outside of the ground.

[0020] By adopting the above technical solution, when the mounting plate is raised and lowered to drive the telescopic sleeve to extend and retract, the ventilation pipe can balance the air pressure inside the two telescopic sleeves. As a result, when the telescopic sleeve is extended, the possibility of external water flow being sucked into the telescopic sleeve can be reduced, thus making the use effect better.

[0021] Optionally, a protective layer is laid on the side of the geotextile away from the permeable pipe. The protective layer includes a stone layer made of multiple crushed stones and a protective net wrapped around the stone layer.

[0022] By adopting the above technical solution, the protective layer can protect the geotextile as a whole, reduce the possibility of damage to the geotextile, thereby ensuring the filtering effect of water flow, making it less likely to increase the sludge accumulation rate in the collection tank, and further reducing the possibility of covering the water supply pump.

[0023] Optionally, the permeable pipe is fixedly connected to several reinforcing columns, which are inserted through the geotextile and the protective layer.

[0024] By adopting the above technical solution, the reinforcement columns can reinforce the laying of geotextile and protective layer, improve the stability of geotextile and protective layer during laying, and enhance the use effect.

[0025] Optionally, the geotextile is embedded with a plurality of connecting rings, which are fitted onto the reinforced column.

[0026] By adopting the above technical solution, the connecting ring can reduce the possibility of geotextile damage when it is fitted onto the reinforced column.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. In case of an emergency, where the water pump is covered by sludge accumulation over a long period, the adjusting screw can be rotated to pull the mounting plate and water pump upwards, thus moving the water pump away from the sludge and reducing the possibility of blockage during water pumping. This ensures the normal operation of the water pump, allowing the water supply pipe to output water in a timely manner and improving the pump's performance. Furthermore, the installation depth of the water pump can be adjusted to allow it to be installed in a more suitable location for pumping, based on actual needs.

[0029] 2. The telescopic sleeve can reduce the possibility of the water in the collection tank being stirred by the rotation of the adjusting screw, thereby reducing the possibility of sludge being stirred upwards, and further reducing the possibility of clogging the water supply pump. In addition, the telescopic sleeve can also restrict the rotation of the mounting plate, making the adjusting screw more stable when controlling the sliding of the mounting plate.

[0038] The present application will be further described in detail below with reference to Figures 1-7.

[0039] This application discloses an artificial wetland ecological purification system. Referring to Figures 1 and 2, the artificial wetland ecological purification system includes a planting layer 1, a filter media layer 2, a pebble layer 3, a permeable pipe 4, a collection tank 5, and a concrete impermeable layer. The planting layer 1, filter media layer 2, and pebble layer 3 are arranged sequentially from top to bottom on the ground. The concrete impermeable layer is arranged at the bottom of the pebble layer 3 and on the sides of the planting layer 1, filter media layer 2, and pebble layer 3. The permeable pipe 4 is arranged at the bottom of the pebble layer 3 and has multiple upward-facing through holes. Geotextile 41 is laid on the surface of the permeable pipe 4, covering the multiple through holes. The collection tank 5 is located on the ground, and the end of the permeable pipe 4 away from the pebble layer 3 is connected to the collection tank 5.

[0040] The planting layer 1 is made by laying soil and planting vegetation in the soil, and the filter filler layer 2 is made of medium sand, coarse sand, medium-coarse sand or gravel.

[0041] Referring to Figure 1, the water collection tank 5 is connected to a water supply pipe 6 and a sludge discharge pipe. A water supply pump 61 is installed at one end of the water supply pipe 6, which is installed inside the water collection tank 5, and the other end extends to the outside of the ground. A lifting assembly 7 is provided inside the water collection tank 5. The lifting assembly 7 includes a mounting plate 71 and an adjusting screw 72. The adjusting screw 72 is installed vertically and rotates in the water collection tank 5. The top of the adjusting screw 72 extends to the outside of the ground. The mounting plate 71 is sleeved and threadedly connected to the adjusting screw 72. The water supply pump 61 is installed on the mounting plate 71.

[0042] In use, rainwater on the ground can be filtered through the planting layer 1, the filter media layer 2, and the pebble layer 3 in sequence, and then enter the permeable pipe 4 and finally collect in the water collection tank 5. Then, the water in the water collection tank 5 can be pumped out through the water supply pipe 6 and the water supply pump 61, so as to provide water for cities, gardens or other areas. The sludge in the water collection tank 5 can also be discharged through the sludge discharge pipe to ensure the water collection effect of the water collection tank 5.

[0043] In case of an emergency, and when the water supply pump 61 is covered due to prolonged sludge accumulation, the adjusting screw 72 can be rotated to pull the mounting plate 71 and the water supply pump 61 up, thereby moving the water supply pump 61 away from the sludge, reducing the possibility of blockage during water pumping, and ensuring the normal use of the water supply pump 61 so that the water supply pipe 6 can output water in a timely manner and improve the performance of the water supply pump 61.

[0044] To facilitate control of the adjusting screw 72, it can be connected to a motor, making it easier to control its rotation. Additionally, for ease of use, in other embodiments, a sludge depth detection instrument can be installed inside the collection tank 5.

[0045] Referring to Figure 1, a telescopic sleeve 73 is provided above the mounting plate 71. The telescopic sleeve 73 includes multiple coaxially distributed sleeve units 731. The sleeve units 731 are fitted onto and slidably connected to adjacent sleeve units 731. Both ends of the telescopic sleeve 73 are fixedly connected to the mounting plate 71 and the top wall of the water collection tank 5, respectively. A telescopic sleeve 73 is also provided below the mounting plate 71, and both ends of the telescopic sleeve 73 are fixedly connected to the mounting plate 71 and the bottom wall of the water collection tank 5, respectively. In addition, the sleeve unit 731 is configured as a prismatic structure.

[0046] In use, as the adjusting screw 72 rotates to control the raising and lowering of the mounting plate 71, the mounting plate 71 can push the telescopic sleeve 73 to extend and retract. The telescopic sleeve 73, in this configuration, reduces the likelihood of the adjusting screw 72 stirring the water in the collection tank 5, thereby reducing the possibility of sludge being stirred upwards, and further reducing the possibility of clogging the water supply pump 61. Furthermore, because the sleeve unit 731 is designed with a prismatic structure, the telescopic sleeve 73 not only isolates the adjusting screw 72 but also restricts the rotation of the mounting plate 71, making the adjusting screw 72 more stable when controlling the sliding of the mounting plate 71.

[0047] Referring to Figures 3 and 4, a scraper 732 is formed at one end of the sleeve unit 731, and a connecting rod 733 is fixedly connected to the inner wall of the other end. A connecting sleeve 734 is fixedly connected to the connecting rod 733. The scraper 732 is sleeved and slidably connected to the adjacent sleeve unit 731, and the connecting sleeve 734 is sleeved and slidably connected to the adjusting screw 72.

[0048] In use, when two adjacent sleeve units 731 slide relative to each other, the scraper 732 can first clean the surface of the adjacent sleeve units 731, making it easier for the two adjacent sleeve units 731 to retract, while reducing the possibility of damage to the connection between the two adjacent sleeve units 731. Furthermore, the combined action of the connecting rod 733 and the connecting sleeve 734 can support the sliding of the sleeve unit 731, thereby increasing the overall stability of the telescopic sleeve 73 and improving the performance. Simultaneously, when the two adjacent sleeve units 731 retract, the sleeve unit 731 can abut against the connecting rod 733 in the adjacent sleeve unit 731, thereby limiting the amount of sliding of the sleeve unit 731, resulting in a better retraction effect.

[0049] Referring to Figure 4, at this time, the end of the sleeve unit 731 facing the connecting rod 733 in the adjacent sleeve unit 731 is provided with a slot 7311, so that when the two adjacent sleeve units 731 are contracted, the slot 7311 can be engaged with the connecting rod 733, thereby improving the integrity between the two adjacent sleeve units 731.

[0050] Referring to Figures 5 and 6, the mounting plate 71 has ventilation holes 711 that connect the interiors of the two telescopic sleeves 73. A ventilation pipe 735 connects to the interior of the telescopic sleeve 73 above the mounting plate 71, with the other end of the ventilation pipe 735 leading to the outside of the ground. When the mounting plate 71 is raised or lowered to extend or retract the telescopic sleeves 73, the ventilation pipe 735 balances the air pressure inside the telescopic sleeves 73. This reduces the likelihood of external water being drawn into the telescopic sleeves 73 when they are extended, resulting in better performance.

[0051] Referring to Figure 7, a protective layer 42 is laid on the side of the geotextile 41 away from the permeable pipe 4. The protective layer 42 includes a stone layer 421 and a protective net 422. The stone layer 421 is made of multiple crushed stones, and the protective net 422 is wrapped around the stone layer 421, thereby forming a whole with the stone layer 421 and the protective net 422. This allows the protective layer 42 to protect the geotextile 41 as a whole, reducing the possibility of damage to the geotextile 41, thereby ensuring the filtering effect on the water flow, making it less likely to increase the sludge accumulation rate in the collection tank 5, and further reducing the possibility of covering the water supply pump 61.

[0052] Referring to Figure 7, the permeable pipe 4 is fixedly connected to several reinforcing columns 43, which are inserted through the geotextile 41 and the protective layer 42; the geotextile 41 is embedded with several connecting rings 411, which are respectively fitted onto several reinforcing columns 43.

[0053] Furthermore, during use, the reinforcing column 43 can reinforce the laying of geotextile 41 and protective layer 42, improve the stability of geotextile 41 and protective layer 42 during laying, and increase the effectiveness of use; and the connecting ring 411 can reduce the possibility of geotextile 41 being damaged when geotextile 41 is fitted onto reinforcing column 43.

[0054] The implementation principle of the artificial wetland ecological purification system in this application embodiment is as follows: rainwater from the ground can be filtered sequentially through the planting layer 1, the filter media layer 2, and the pebble layer 3, and finally collect in the collection tank 5. The water in the collection tank 5 can then be pumped out through the water supply pipe 6 and the water supply pump 61, thus providing a water source for cities, gardens, or other areas. In case of an emergency, if the water supply pump 61 is covered due to prolonged sludge accumulation, the adjusting screw 72 can be rotated to pull the mounting plate 71 and the water supply pump 61 upwards, thereby moving the water supply pump 61 away from the sludge, reducing the possibility of blockage during pumping, and ensuring the normal operation of the water supply pump 61 so that the water supply pipe 6 can output water in a timely manner, improving the performance of the water supply pump 61.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
