Description

Technical Field

[0001] This invention belongs to the field of water resource protection technology, specifically relating to a device for constructing an ecological barrier in the surface and groundwater interaction zone. Background Technology

[0002] The surface-groundwater interaction zone, also known as the surface water and groundwater interaction zone, is an important concept in surface hydrology and hydroecology. It refers to the area where surface water and groundwater interact. The surface-groundwater interaction zone is usually located below the surface water flow and extends to the riparian zone and the water-saturated areas on both sides, including sediments, bedrock, etc. This is the place where surface water and groundwater mix, migrate and exchange with each other. It is a key interface for the dynamic interaction between the two. Biogeochemical processes are extremely active in the interaction zone, which is an important area for maintaining the health and function of the aquatic ecosystem.

[0003] Pollutants in surface water, such as pesticides, fertilizers, heavy metals, and organic pollutants in industrial wastewater, can seep into the ground and pollute groundwater. These pollutants may alter the chemical composition, physical properties, or biological characteristics of groundwater, thereby affecting its quality. They can also disrupt the original ecological balance of the interaction zone, leading to a decline in biodiversity. Groundwater is an important drinking water source in many regions.

The surface water can be biodegraded, aerated and decomposed and purified by plants in sequence through the purification pond, aeration pond and wetland pond, so as to ensure that the surface water flowing into the interaction zone is fully purified. Through the multiple planting mechanisms in the wetland pond, the biodegradation ability of aquatic plants can be used to absorb and transform pollutants in the surface water, improve water quality, and thus prevent pollutants contained in the surface water from seeping into the ground and polluting the groundwater with the water flow.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1:

[0039] Please see Figures 1 to 8 As shown, a device for constructing an ecological barrier in the surface-groundwater interaction zone includes:

[0040] Barrier construction pool 1;

[0041] A purification pool 2 is set on one side of the barrier construction pool 1, an aeration pool 3 is set on the middle side of the barrier construction pool 1, a wetland pool 4 is set on the other side of the barrier construction pool 1, a purification mechanism 5 is installed between the inner walls of the two sides of the wetland pool 4, multiple interception mechanisms 6 are embedded at one end of the barrier construction pool 1, and a monitoring mechanism 7 is installed on the upper part of the inner wall of both the purification pool 2 and the wetland pool 4.

[0042] The purification mechanism 5 includes a fixing rod 51, a mounting screw 52, ​​a fastening nut 53, and a planting mechanism 54. There are two fixing rods 51, and both fixing rods 51 are installed between the inner walls of both sides of the wetland pool 4. There are multiple mounting screws 52, fastening nuts 53, and planting mechanisms 54. Multiple mounting screws 52 are installed on the top of the two fixing rods 51 respectively, multiple fastening nuts 53 are installed on the outer surface of the multiple mounting screws 52 respectively, and multiple planting mechanisms 54 are installed between the top of the two fixing rods 51.

[0043] Depend on Figures 1 to 4 It can be seen that two barrier nets 8 are installed between the inner walls of both sides of the purification tank 2, and multiple biological filter media 9 are placed between the two barrier nets 8. An aeration pipe 10 is installed on the bottom inner wall of the aeration tank 3, and multiple flow pipes 11 are installed on the lower part of the inner walls of both sides of the aeration tank 3 and the lower part of the inner wall of one side of the wetland tank 4.

[0044] The planting mechanism 54 includes a floating plant frame 541, an isolation net 542, mounting holes 543, connecting rods 544, and a submerged plant trough 545. The isolation net 542 is installed between the inner walls of both sides of the floating plant frame 541. There are two mounting holes 543, which are respectively opened on the top two sides of the floating plant frame 541. There are four connecting rods 544, which are respectively installed at the four corners of the bottom of the floating plant frame 541. The submerged plant trough 545 is installed between the bottom ends of the four connecting rods 544. The floating plant frame 541 is installed on the outer surface of the corresponding two mounting screws 52 through the mounting holes 543.

[0045] As can be seen from the above, firstly, the ecological barrier construction device is installed at the interaction zone around the river, aiming to allow surface water to safely flow into groundwater after being treated by the barrier construction pool 1. The surface water first undergoes preliminary filtration through the interception mechanism 6, and then enters the purification pool 2. In the purification pool 2, microorganisms attach to the surface of the biological filter media 9 to form a biofilm, using biochemical action to degrade pollutants such as organic matter and ammonia nitrogen in the water. After being treated by the purification pool 2, the water flows into the aeration pool 3 through the flow pipe 11. In the aeration pool 3, air is introduced into the water through the aeration pipe 10 to increase the dissolved oxygen content in the water, thereby promoting the reproduction and activity of aerobic microorganisms and further degrading the organic matter in the sewage. Next, the water flows into the wetland pool 4 again through the flow pipe 11. In the wetland pool 4, floating aquatic plants are planted in the floating plant frame 541 and submerged plant trough 545. Submerged aquatic plants fully utilize their biodegradation capabilities to absorb and transform pollutants in surface water, further improving water quality. This series of processes—biodegradation, aeration decomposition, and plant purification—ensures that the surface water flowing into the interaction zone is comprehensively purified. This not only prevents pollutants in the surface water from seeping into the ground and polluting groundwater, but also ensures the healthy operation of the ecosystem and effectively protects water resources. In addition, the design of the device also takes into account the ease of maintenance. By rotating the fastening nut 53 to remove it from the mounting screw 52, ​​the planting mechanism 54 can be easily disassembled from the fixing rod 51, allowing for the replacement of the aquatic plants planted inside. In summary, this ecological barrier construction device plays an important role in purifying water quality, protecting water resources, and maintaining the health of the ecosystem, while its design also facilitates daily maintenance and plant replacement.

[0046] For details, please refer to Figures 1 to 4 As shown, the floating plant frame 541 is configured as a convex frame structure, the diameter of the mounting hole 543 is larger than the diameter of the mounting screw 52, ​​multiple flow pipes 11 are equipped with solenoid valves, and the mesh diameter of the barrier net 8 is smaller than the diameter of the biological filter media 9.

[0047] As can be seen from the above, it is convenient to install the floating plant frame 541 on the fixing rod 51, and ensure that the mounting screw 52 can easily pass through the mounting hole 543 for fixing. The solenoid valve is used to control the flow of fluid in the flow pipe 11. The barrier net 8 can ensure the flow of water while preventing the leakage of biological filter media 9, and ensure that the biological filter media 9 will not be lost through the barrier net 8.

[0048] Example 2:

[0049] refer to Figures 5 to 7 As shown, several installation ports 12 are provided on the inner wall of the other side of the purification pool 2. Each of the several installation ports 12 has a sealing groove 13 on its inner wall. Each of the several sealing grooves 13 has a positioning groove 14 on the upper part of the inner wall on both sides.

[0050] The interception mechanism 6 includes permeable concrete 61, sealing strip 62, mounting groove 63 and positioning mechanism 64. The permeable concrete 61 is installed inside the mounting opening 12, the sealing strip 62 is installed in the middle of the outer surface of the permeable concrete 61, the mounting groove 63 is opened in the middle of the top of the permeable concrete 61, and the positioning mechanism 64 is installed on the bottom inner wall of the mounting groove 63.

[0051] The positioning mechanism 64 includes a fixed frame 641, a limiting groove 642, a positive and negative screw 643, an adjusting block 644, and a positioning frame 645. The fixed frame 641 is installed on the bottom inner wall of the mounting groove 63. There are two limiting grooves 642 and two positioning frames 645. The two limiting grooves 642 are respectively opened on both sides of the bottom inner wall of the fixed frame 641. The positive and negative screw 643 is installed between the two inner walls of the fixed frame 641 through bearings. The adjusting block 644 is installed in the middle of the outer surface of the positive and negative screw 643. The two positioning frames 645 are respectively installed on both sides of the outer surface of the positive and negative screw 643.

[0052] As can be seen from the above, the unique porous structure of the permeable concrete 61 can effectively filter out some pollutants in the surface water, such as oil and heavy metals, thereby significantly reducing the pollution of groundwater by surface runoff. After being treated and filtered by the permeable concrete 61, the surface water is filtered and enters the barrier construction pool 1. When the permeable concrete 61 needs to be replaced, the operation is also convenient. The rotation of the adjusting block 644 can drive the rotation of the positive and negative screws 643. The positive and negative screws 643 then drive the two positioning frames 645 on them to move towards the middle. Under the guiding and limiting action of the limiting groove 642, the positioning frame 645 can be stably moved out of the positioning groove 14, thereby canceling the positioning. At this time, the permeable concrete 61 can be easily removed from the installation port 12, and the sealing strip 62 will also be removed from the sealing groove 13. This design greatly enhances the convenience of maintenance.

[0053] Preferred, Reference Figures 5 to 7 As shown, the fixing frame 641, sealing strip 62 and sealing groove 13 are all set as U-shaped structures, the positioning frame 645 is set as an L-shaped structure, and the positioning frame 645 is engaged with the positioning groove 14.

[0054] As can be seen from the above, the U-shaped fixing frame 641 can enhance the stability of the structure, the U-shaped sealing strip 62 and the corresponding sealing groove 13 can help to provide a better sealing effect, and the L-shaped structure can facilitate the snapping and fixing of the positioning frame 645, so as to achieve precise positioning and firm fixation.

[0055] Example 3:

[0056] refer to Figure 8As shown, the monitoring mechanism 7 includes a mounting frame 71, a pH sensor 72, a conductivity sensor 73, a dissolved oxygen sensor 74, a turbidity sensor 75, and a heavy metal sensor 76. The mounting frame 71 is installed on the inner wall of the wetland pool 4, and the pH sensor 72, conductivity sensor 73, dissolved oxygen sensor 74, turbidity sensor 75, and heavy metal sensor 76 are installed sequentially from front to back on the outer surface of the mounting frame 71.

[0057] As can be seen from the above, the T-shaped mounting bracket 71 allows for the secure installation of multiple sensors. The two monitoring units 7 are respectively installed in the purification tank 2 and the wetland tank 4, enabling real-time monitoring and comprehensive understanding of water quality changes in these two tanks. Specifically, the pH sensor 72 measures the acidity or alkalinity of the water, which is crucial for assessing the chemical properties of the water and understanding potential chemical pollution. The conductivity sensor 73 measures the electrical conductivity of the water; this indicator reflects the amount of ions in the water and is an important basis for judging water purity and mineral content. The dissolved oxygen sensor 74 measures the dissolved oxygen content of the water, which is essential for assessing the biological activity of the water and supporting aquatic life. The ability of organisms to survive is crucial. Turbidity sensor 75 measures the degree of turbidity in water, helping to quickly identify possible suspended particles and pollutants in the water. Heavy metal sensor 76 measures the concentration and content of heavy metals in the water, enabling timely detection and early warning of heavy metal pollution, preventing potential threats to the ecosystem and human health. Together, these sensors have the ability to accurately identify pollutants in the surface water-groundwater interaction zone, thereby achieving real-time monitoring, early warning, and scientific management of water quality. By integrating advanced monitoring technologies and data analysis methods, the system can achieve real-time monitoring and early warning of pollution in the interaction zone, providing important support for the protection of water resources and the ecological environment.

[0058] Preferred, Reference Figure 8 As shown, the mounting bracket 71 is configured as a T-shaped structure, and the pH sensor 72, conductivity sensor 73, dissolved oxygen sensor 74, turbidity sensor 75 and heavy metal sensor 76 are all electrically connected to the controller.

[0059] As can be seen from the above, the T-shaped mounting bracket 71 can provide stronger support and stability, ensuring that sensor data can be transmitted to the controller in real time, realizing the real-time acquisition and processing of environmental monitoring data, and providing data support for system control.

[0060] Application example:

[0061] This design is applied to areas where surface water and groundwater frequently interact and pose potential pollution risks. In agricultural irrigation areas, excessive use of fertilizers and pesticides can lead to excessive levels of pollutants such as nitrogen and phosphorus in surface water. These pollutants may seep into the groundwater system through soil infiltration. Industrial activities such as industrial wastewater discharge, oil depot leaks, or heavy metal emissions can severely pollute surface water, thereby threatening groundwater safety. During urban expansion, rainwater runoff carrying urban waste, oil pollution, and other pollutants may flow into surface water bodies. Simultaneously, large-scale urban groundwater extraction and frequent interactions between surface water and groundwater increase the risk of pollution. This design increases the risk of pollution. By setting up an interception mechanism 6, it can filter out pollutants such as suspended solids, oil, and heavy metals from surface water, reducing their chance of entering groundwater. By setting up a purification mechanism 5, it can absorb and transform pollutants in surface water using the biodegradation capabilities of aquatic plants, thereby improving water quality. By setting up a monitoring mechanism 7, it can use sensors and data analysis technology to monitor the types and concentrations of pollutants in the surface water-groundwater interaction zone in real time, provide timely warnings of pollution conditions, and provide a scientific basis for management decisions. In this way, a comprehensive ecological barrier system is formed in the surface water-groundwater interaction zone.
