Description

Technical Field

[0001] The present invention belongs to the technical field of water resource protection, and in particular relates to a device for constructing an ecological barrier in a surface-groundwater interaction zone. Background Art

[0002] The surface-groundwater interaction zone, also known as the surface water-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 the key interface for the dynamic interaction between the two. The biogeochemical processes in the interaction zone are extremely active, and it 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 in industrial wastewater, and organic pollutants, will seep into the ground with the water flow and pollute groundwater. These pollutants may change the chemical composition, physical properties or biological properties of groundwater, thereby affecting its quality. They will also destroy the original ecological balance of the interaction zone and lead to a decline in biodiversity. Groundwater is an important source of drinking water in many areas. Once groundwater is polluted, the originally clean water resources become undrinkable, which will aggravate the problem of water shortage. Summary of the Invention

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] Embodiment 1:

[0039] Please refer toFigures 1 to 8 As shown in the figure, an ecological barrier construction device for the surface and groundwater interaction zone includes:

[0040] A barrier construction pool 1;

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

[0042] The purification mechanism 5 includes fixing rods 51, mounting screws 52, fastening nuts 53 and a planting mechanism 54. There are two fixing rods 51, and both fixing rods 51 are installed between the two inner walls on both sides of the wetland pool 4. There are a plurality of mounting screws 52, fastening nuts 53 and planting mechanisms 54. The plurality of mounting screws 52 are respectively installed at the tops of the two fixing rods 51. The plurality of fastening nuts 53 are respectively installed on the outer surfaces of the plurality of mounting screws 52. The plurality of planting mechanisms 54 are all installed between the tops of the two fixing rods 51.

[0043] As Figures 1 to 4 can be seen, two blocking nets 8 are commonly installed between the two inner walls on both sides of the purification pool 2. Between the two blocking nets 8, a plurality of biological filter materials 9 are placed. An aeration pipe 10 is installed on the bottom inner wall of the aeration pool 3. A plurality of flow pipes 11 are installed on the lower parts of the two inner walls on both sides of the aeration pool 3 and the lower part of one side inner wall of the wetland pool 4;

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

[0045] As can be seen from the above, first of all, the ecological barrier construction device is installed at the interaction zone around the river, aiming to make the surface water flow safely into the groundwater after being treated in the barrier construction pool 1. The surface water is first preliminarily filtered by 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, and use biochemical action to degrade pollutants such as organic matter and ammonia nitrogen in the water. After being treated in the purification pool 2, the water flows into the aeration pool 3 through the circulation pipe 11. In the aeration pool 3, air is filled into the water through the aeration pipeline 10 to increase the dissolved oxygen content in the water body, thereby promoting the reproduction and activities of aerobic microorganisms and further degrading the organic matter in the sewage. Next, the water flows into the wetland pool 4 through the circulation pipe 11 again. In the wetland pool 4, by planting floating aquatic plants in the floating plant frame 541 and submerged aquatic plants in the submerged plant trough 545, the biodegradation ability of the aquatic plants is fully utilized to absorb and transform the pollutants in the surface water, further improving the water quality. This series of processes - biodegradation, aeration decomposition, and plant purification treatment - ensure the comprehensive purification of the surface water flowing into the interaction zone. This not only avoids the pollutants contained in the surface water from seeping into the ground with the water flow and polluting the groundwater, but also guarantees the healthy operation of the ecosystem and effectively protects water resources. In addition, the design of this device also takes into account the convenience of maintenance. By removing the rotating fastening nut 53 from the installation screw 52, the planting mechanism 54 can be easily disassembled from the fixed rod 51, so as to replace the aquatic plants planted therein. To sum up, the ecological barrier construction device plays an important role in purifying water quality, protecting water resources, and maintaining the health of the ecosystem, and its design is also convenient for daily maintenance and plant replacement.

[0046] Specifically, referring to Figures 1 to 4 As shown, the floating plant frame 541 is set as a convex frame structure. The diameter of the installation hole 543 is larger than the diameter of the installation screw 52. Solenoid valves are arranged on multiple circulation pipes 11. The mesh diameter of the blocking 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 fixed rod 51 to ensure that the installation screw 52 can easily pass through the installation hole 543 for fixation. The solenoid valve is used to control the flow of fluid in the circulation pipe 11. The blocking net 8 can ensure the flow of water while preventing the leakage of the biological filter media 9 and ensuring that the biological filter media 9 will not be lost through the blocking net 8.

[0048] Embodiment 2:

[0049] Referring to Figures 5 to 7 As shown, a number of installation openings 12 are opened on the inner wall on the other side of the purification pool 2. Sealing grooves 13 are opened on the inner walls of the number of installation openings 12. Positioning grooves 14 are opened on the upper parts of the inner walls on both sides of the number of sealing grooves 13;

[0050] The interception mechanism 6 includes permeable concrete 61, a sealing strip 62, a mounting groove 63 and a 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 end of the permeable concrete 61. 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 rod 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 rod 643 is installed between the inner walls on both sides 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 rod 643. The two positioning frames 645 are respectively installed on both sides of the outer surface of the positive and negative screw rod 643.

[0052] As can be seen from the above, through the unique pore structure on the permeable concrete 61, some pollutants in surface water, such as oil stains and heavy metals, can be effectively filtered out, thus significantly reducing the pollution of surface runoff to groundwater quality. After being treated, filtered and intercepted 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 process is also convenient. By rotating the adjusting block 644, the positive and negative screw rod 643 can be driven to rotate. The positive and negative screw rod 643 then drives the two positioning frames 645 on it to move towards the middle. Under the guiding and limiting action of the limiting groove 642, the positioning frame 645 can stably move out of the positioning groove 14, thus canceling the positioning. At this time, the permeable concrete 61 can be conveniently taken out from the mounting opening 12, and at the same time, the sealing strip 62 will also be disengaged from the sealing groove 13. Such a design greatly enhances the convenience of maintenance.

[0053] Preferably, as shown in Figures 5 to 7 the fixed frame 641, the sealing strip 62 and the sealing groove 13 are all set as a U-shaped structure. The positioning frame 645 is set as an L-shaped structure, and the positioning frame 645 is clamped with the positioning groove 14.

[0054] As can be seen from the above, the U-shaped fixed frame 641 can enhance the structural stability. The clamping of the U-shaped sealing strip 62 with the corresponding sealing groove 13 helps to provide a better sealing effect. The L-shaped structure facilitates the clamping and fixing of the positioning frame 645, realizing precise positioning and firm fixing.

[0055] Embodiment 3:

[0056] Refer to Figure 8As shown in the figure, 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 pond 4. The pH sensor 72, conductivity sensor 73, dissolved oxygen sensor 74, turbidity sensor 75, and heavy metal sensor 76 are sequentially installed on the outer surface of the mounting frame 71 from front to back.

[0057] As can be seen from the above, the T-shaped mounting frame 71 can achieve firm installation of multiple sensors. And the two monitoring mechanisms 7 are respectively installed in the purification pond 2 and the wetland pond 4, which can monitor the water quality changes in these two ponds in real time and comprehensively. Among them, the pH sensor 72 measures the acidity and alkalinity of the water quality, which is crucial for evaluating the chemical properties of the water body and understanding possible chemical pollution. The conductivity sensor 73 measures the conductivity of the water quality, and this indicator can reflect the amount of ions in the water and is an important basis for judging the water quality purity and mineral content. The dissolved oxygen sensor 74 measures the dissolved oxygen content of the water quality, which is crucial for evaluating the biological activity of the water body and the ability to support the survival of aquatic organisms. The turbidity sensor 75 measures the turbidity of the water quality to help quickly identify possible suspended particles and pollutants in the water body. The heavy metal sensor 76 measures the concentration and content of heavy metal substances in the water quality, which can timely detect and warn of heavy metal pollution and prevent its potential threat to the ecosystem and human health. These sensors together have the ability to accurately identify pollutants in the surface and groundwater interaction zone, and then realize the real-time monitoring, warning, and scientific management of the water quality status. By integrating advanced monitoring technologies and data analysis methods, the system can realize the real-time monitoring and warning of the pollution status in the interaction zone, providing important support for protecting water resources and the ecological environment.

[0058] Preferably, referring to Figure 8 As shown in the figure, the mounting frame 71 is set as a T-shaped structure. 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 frame 71 can provide stronger support and stability, ensuring that sensor data can be transmitted to the controller in real time, realizing the real-time collection 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 interact frequently and there are potential pollution risks. In farmland irrigation areas, the excessive use of chemical fertilizers and pesticides may lead to excessive levels of pollutants such as nitrogen and phosphorus in surface water. These pollutants may penetrate into the groundwater system through the soil. Industrial activities such as industrial wastewater discharge, oil depot leakage, or heavy metal discharge may seriously pollute surface water, thus threatening the safety of groundwater. During the process of urban expansion, pollutants such as urban garbage and oil stains carried by rainwater runoff may flow into surface water bodies. At the same time, the large amount of urban groundwater extraction and the frequent interaction between surface water and groundwater increase the pollution risk. Through the installation of an interception mechanism 6, this design can filter out pollutants such as suspended solids, oil stains, and heavy metals in surface water, reducing the chance of their entry into groundwater. Through the installation of a purification mechanism 5, using the biodegradation ability of aquatic plants, it can absorb and transform pollutants in surface water, improving water quality. Through the installation of a monitoring mechanism 7, using sensors and data analysis technology, it can monitor the types and concentrations of pollutants in the surface groundwater interaction zone in real time, timely warning of pollution situations, and providing a scientific basis for management decisions, thus forming a comprehensive ecological barrier system in the surface groundwater interaction zone.

[0062] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
