Description

Technical Field

[0001] This utility model relates to the field of semi-artificial wetland technology, specifically a semi-artificial wetland filler regeneration and environmental purification structure. Background Technology

[0002] Semi-artificial wetlands are semi-artificial structures created by utilizing, modifying, and incorporating human intervention into existing natural wetland systems such as marshes, ponds, shallow lakes, or floodplains. Through artificial facilities such as irrigation canals and control gates, wastewater or rainwater requiring treatment is introduced into this natural wetland. The plants, microorganisms, soil, and naturally occurring hydrological processes within the wetland work together to purify the water. This form of wastewater and rainwater purification technology is low-cost and highly ecologically beneficial, utilizing the natural ecosystem without requiring the reconstruction of substrates and plant communities from scratch. While purifying the water, it also provides valuable habitats for native wildlife, typically resulting in higher biodiversity. However, existing semi-artificial wetlands suffer from inadequate control of influent water quality. If the concentration of pollutants and toxic substances in the wastewater is too high, it may cause irreversible damage to the original natural ecosystem, failing to achieve sustainable wastewater purification. Utility Model Content

[0003] The purpose of this utility model is to provide a semi-artificial wetland filler regeneration environmental purification structure to address the problem that improper control of influent water quality in existing semi-artificial wetlands may cause irreversible damage to the original natural ecosystem and prevent the realization of sustainable sewage purification functions.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a semi-artificial wetland filler regeneration and environmental purification structure, comprising:

[0005] Natural wetlands, with wetland plants planted in the filler layer inside, and an ecological embankment set on the outside, with an outlet provided in the ecological embankment;

[0006] The sewage distribution pipeline includes a main pipeline and branch pipelines, through which sewage flows into the main pipeline and enters the natural wetland;

[0007] The dilution tank is connected to the main pipeline and to the inlet of the branch pipeline via the outlet pipe. An online water quality monitoring instrument is installed on the dilution tank, which is also connected to the water supply pipeline. Control valves are installed on the main pipeline, the outlet pipe, and the water supply pipeline.

[0008] As a further description of the above technical solution:

[0009] Several online water quality monitoring instruments are arranged at intervals around the dilution tank.

[0010] As a further description of the above technical solution:

[0011] The dilution tank is equipped with aeration equipment.

[0012] As a further description of the above technical solution:

[0013] The water supply pipeline is connected to an externally installed water purification pipeline and / or rainwater pipeline.

[0014] As a further description of the above technical solution:

[0015] The control valve is a solenoid valve.

[0016] As a further description of the above technical solution:

[0017] The diversion pipeline includes a first diversion pipe and a second diversion pipe. Several first diversion pipes are led out from the outlet end of the outlet pipe. The first diversion pipes extend to the perimeter of the ecological embankment. Several second diversion pipes are led out from the first diversion pipes. The second diversion pipes pass through the ecological embankment and extend above the natural wetland. An overflow weir is set below the outlet end of the second diversion pipes on the ecological embankment. Several overflow outlets connected to the overflow channels inside the overflow weir are set on the overflow weir.

[0018] As a further description of the above technical solution:

[0019] The size of the inlet side of the overflow port is smaller than the size of the outlet side of the overflow port, and the overflow port forms a gradually expanding, arc-shaped guide surface between the inlet side and the outlet side.

[0020] As a further description of the above technical solution:

[0021] The ecological embankment is also equipped with a liquid level sensor for sensing the liquid level of sewage in the natural wetland.

[0022] In summary, by adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0023] 1. In this semi-artificial wetland, when sewage is injected into a natural wetland, the sewage enters a dilution tank via a main pipeline. An online water quality monitoring instrument detects the sewage quality. When the sewage's indicators are within the natural wetland's sewage purification capacity, the sewage is directly introduced into the natural wetland via an outlet pipe and branch pipes for treatment. However, when the sewage quality exceeds the standards, the control valve on the main pipeline reduces the amount of sewage entering the dilution tank, and a water supply pipe introduces purified water into the dilution tank to dilute the sewage until all indicators meet the standards before it is introduced into the natural wetland for further treatment. This structural design allows for the detection and regulation of the sewage entering the natural wetland, ensuring it meets the requirements of the natural wetland's sewage purification process. This avoids excessive sewage treatment load on the natural wetland, which could damage the internal and surrounding vegetation ecosystem, thus achieving sustainable sewage purification.

[0024] 2. By using diversion pipelines, sewage is introduced from all sides of the natural wetland, transforming the conventional linear source method of sewage introduction into the natural wetland through a single or localized sewage inlet into the aforementioned area source method. This allows sewage to rapidly diffuse throughout the natural wetland, improving sewage introduction and distribution efficiency as well as purification efficiency. Combined with the gradually expanding, arc-shaped overflow outlets on the overflow weir along the water flow direction, the range of sewage introduction into the natural wetland can be further expanded, further enhancing the aforementioned effects.

[0032] Example 1:

[0033] Please see Figure 1 This utility model provides a technical solution: a semi-artificial wetland filler regeneration and environmental purification structure, comprising:

[0034] Natural wetland 1, with wetland plants planted in the filler layer inside, and an ecological embankment 2 set on the outside of it, with an outlet provided in the ecological embankment 2;

[0035] The sewage distribution pipeline includes a main pipeline 3 and a branch pipeline. Sewage flows into the main pipeline 3 and enters the natural wetland 1 through the branch pipeline.

[0036] The dilution tank 4 is connected to the main pipeline 3 and the inlet of the branch pipeline is connected to the outlet pipeline 5. The dilution tank 4 is equipped with an online water quality monitoring instrument 6, which is also connected to the water supply pipeline 7. Control valves are installed on the main pipeline 3, the outlet pipeline 5, and the water supply pipeline 7.

[0037] The control valve is a solenoid valve, which improves the efficiency of adjusting the opening of the pipeline cavity and the accuracy of regulating the internal liquid flow.

[0038] The working principle of the semi-artificial wetland filler regeneration environmental purification structure in this embodiment includes: when sewage is injected into the natural wetland 1, the sewage enters the dilution tank 4 through the main pipeline 3. The online water quality monitoring instrument 6 detects the sewage quality. When the various indicators of the sewage are within the sewage purification capacity range of the natural wetland 1, the sewage is directly introduced into the natural wetland 1 through the outlet pipe 5 and the diversion pipeline for sewage treatment. When the sewage quality exceeds the standard, the amount of sewage entering the dilution tank 4 is reduced by adjusting the control valve of the main pipeline 3, and the water supply pipeline 7 introduces clean water into the dilution tank 4 to dilute the sewage until the various indicators of the sewage meet the standards, and then it is introduced into the natural wetland 1 for sewage treatment. Through the above structural design, the water quality of the sewage introduced into the natural wetland 1 can be detected and adjusted to meet the usage requirements of the sewage purification process of the natural wetland 1, avoiding excessive sewage treatment load on the natural wetland 1 and causing damage to the internal and surrounding vegetation ecology, thus achieving a sustainable sewage purification function.

[0039] Example 2:

[0040] Please see Figure 1 The figure shows a semi-artificial wetland filler regeneration environmental purification structure provided in Embodiment 2 of this utility model. Based on the above embodiments, this embodiment further improves upon the following technical solutions: Several online water quality monitoring instruments 6 are arranged at intervals around the dilution tank 4. This allows for multi-point water quality testing of the wastewater in the dilution tank 4. When the water quality test results at all points meet the standards, the wastewater is then introduced into the natural wetland 1. This avoids misjudgments of water quality compliance caused by insufficient mixing of wastewater and purified water, or uneven distribution of pollutants in the water, which is common in conventional single or localized water quality testing applications. This ensures the sustainable operation of the wastewater purification function of the natural wetland 1. An aeration device 8 is installed in the dilution tank 4 to agitate the wastewater, ensuring thorough mixing of wastewater and purified water and uniform distribution of pollutants in the water, thus making water quality testing more accurate.

[0041] Example 3:

[0042] Please see Figure 1 The figure shows a semi-artificial wetland filler regeneration environmental purification structure provided in Embodiment 3 of this utility model. Based on the above embodiments, this embodiment further makes the following improved technical solutions: the water supply pipeline 7 is connected to the external clean water pipeline and / or rainwater pipeline, thereby realizing the supply of sewage dilution water from multiple sources and reducing the cost of clean water supply.

[0043] Example 4:

[0044] Please see Figure 1-2The figure shows a semi-artificial wetland filler regeneration environmental purification structure provided in Embodiment 4 of this utility model. Based on the above embodiments, this embodiment further improves upon the following technical solutions: The diversion pipeline includes a first diversion pipe 9 and a second diversion pipe 10. Several first diversion pipes 9 extend from the outlet end of the outlet pipe 5, reaching the perimeter of the ecological dam 2. Several second diversion pipes 10 extend from the first diversion pipes 9, passing through the ecological dam 2 and extending above the natural wetland 1. An overflow weir 11 is provided below the outlet end of the second diversion pipes 10 in the ecological dam 2. Several overflow outlets of overflow channels 12 connected to the overflow weir 11 are provided on the overflow weir 11. Wastewater flows sequentially through the first diversion pipe 9 and the second diversion pipe 10, then enters the overflow channel 12, and finally flows into the natural wetland 1 through the overflow outlets.

[0045] The size of the inlet side 13 of the overflow port is smaller than the size of the outlet side 14 of the overflow port, and the overflow port forms a gradually expanding, arc-shaped guide surface 15 between the inlet side 13 and the outlet side 14.

[0046] By diverting sewage through a branch pipeline, wastewater is introduced from all sides of the natural wetland 1, transforming the conventional linear source method of sewage inflow into the natural wetland 1 from a single or partial sewage inlet to the aforementioned area source method. This allows the sewage to rapidly diffuse throughout the natural wetland 1, improving both the sewage inflow and distribution efficiency and the purification efficiency. Furthermore, the overflow weir 11, with its gradually expanding, arc-shaped overflow outlet along the water flow direction, further expands the area through which sewage enters the natural wetland 1, enhancing the aforementioned effects.

[0047] Example 5:

[0048] Please see Figure 1 The figure shows a semi-artificial wetland filler regeneration environmental purification structure provided in Embodiment 5 of this utility model. Based on the above embodiments, this embodiment further improves upon the following technical solution: a level sensor is also installed on the ecological dam 2 to sense the sewage level within the natural wetland 1. This enables monitoring of the sewage level within the natural wetland 1, indicating the amount of sewage flowing into the natural wetland 1 through the sewage distribution pipeline. This prevents excessive sewage from overflowing the ecological dam 2 and causing pollution of the surrounding environment, or prevents the sewage level from being too low, which could affect the sewage purification efficiency of the natural wetland 1 and the ecological conditions such as plant growth.

[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
