Description

Technical Field

[0001] This utility model relates to the field of environmental protection and water treatment technology, and in particular to a soil infiltration and purification device with a biomimetic root system structure. Background Technology

[0002] Soil infiltration purification is a water treatment technology that utilizes soil media to filter, adsorb, and degrade pollutants. It is widely used in wastewater treatment, rainwater purification, and ecological restoration. Soil infiltration systems typically consist of multiple layers, achieving water purification through the synergistic action of physical, chemical, and biological processes. However, traditional soil infiltration devices often face problems in practical applications, such as unstable purification efficiency, susceptibility to clogging, and high maintenance costs.

[0003] Current soil infiltration devices mostly employ a uniformly filled media structure. While this can remove pollutants to some extent, the relatively simple media distribution and water flow path can easily lead to localized siltation or short-circuiting, thus affecting the overall purification effect. Furthermore, some devices attempt to improve performance by increasing the types of media or optimizing the filling method, but these methods often require complex construction processes and may increase the difficulty of operation and management. Therefore, there is an urgent need for a new type of soil infiltration device that can simulate natural root structures, optimize water flow distribution, and improve purification efficiency. Utility Model Content

[0005] This invention is implemented as follows: a soil infiltration and purification device with a biomimetic root system structure includes a main frame, a layered flow guiding component, and a biomimetic root system structure module. The main frame is a rectangular box structure with multiple internal partitions dividing it into several independent functional zones. The layered flow guiding component is located inside the main frame and fixedly connected to the partitions, guiding wastewater flow within different functional zones. The biomimetic root system structure module is installed below the layered flow guiding component and is connected to it via multiple sets of branch pipes, simulating a natural root system structure to filter and adsorb wastewater.

[0006] The main frame has a water inlet at the top and a water outlet at the bottom. The water inlet connects to an external sewage pipe, while the water outlet connects to a subsequent treatment system via a drainage pipe. Multiple inspection holes with sealing caps are provided on the side walls of the main frame for easy regular cleaning and maintenance. The bottom of the main frame is equipped with adjustable support legs to accommodate installation needs in different terrain conditions.

[0007] Preferably, the layered flow guiding assembly includes a first flow guiding plate, a second flow guiding plate, and an intermediate connector. Both the first and second flow guiding plates have a wave-shaped structure and are fixedly connected by the intermediate connector to form staggered flow guiding channels. The surface of the first flow guiding plate is provided with multiple flow guiding grooves, the depth of which gradually decreases from the center to both sides, allowing the sewage to be evenly distributed along the flow guiding grooves. The surface of the second flow guiding plate is provided with multiple through holes, the diameter of which gradually increases from the center to the edge, for adjusting the flow velocity and flow rate of the sewage.

[0008] Preferably, the biomimetic root system structure module includes a main pipe, branch pipes, and an adsorption unit. The main pipe is vertically installed below the layered flow guiding component, and its two ends are connected to the first flow guiding plate and the second flow guiding plate, respectively. The branch pipes extend horizontally from both sides of the main pipe, and the adsorption unit is provided at the end of the branch pipe.

The inner filter layer is composed of activated carbon particles, the middle filter layer is composed of zeolite particles, and the outer filter layer is composed of ceramic particles. The three layers are separated and fixed by a metal mesh. The adsorption unit is externally wrapped with a flexible protective cover made of polyurethane to protect the adsorption unit from external impact damage.

[0010] Preferably, the main pipeline is equipped with a diversion plate inside, which divides the main pipeline into multiple independent chambers, each of which is connected to the adsorption unit through a branch pipeline. The surface of the diversion plate is provided with multiple diversion holes, the diameter of which gradually decreases from top to bottom, to control the distribution ratio of sewage in the chambers.

[0011] Preferably, the branch pipe is equipped with spiral blades inside, which are continuously distributed along the axial direction of the branch pipe to increase the flow path length of sewage within the pipe and simultaneously increase the contact time between sewage and the adsorption unit. The surface of the spiral blades is coated with a biofilm layer composed of microbial communities to further degrade organic pollutants in the sewage.

[0012] Preferably, the main frame is equipped with a backwashing system, which includes a backwash pipe, nozzles, and a control valve. The backwash pipe is installed at the top of the main frame, with one end connected to an external water source and the other end connected to a stratified flow guiding assembly via a nozzle. The control valve is located in the middle of the backwash pipe and is used to control the opening and closing of the backwashing system.

[0019] This utility model provides a soil infiltration and purification device with a biomimetic root system structure, the structure and specific implementation method of which are described below. Figure 1The overall structural diagram shows that the main frame 1 is a rectangular box structure, which is divided into multiple independent functional areas by multiple partitions. The layered flow guiding component 2 is set inside the main frame 1 and fixedly connected to the partitions. The biomimetic root system module 3 is installed below the layered flow guiding component 2 and is connected to the layered flow guiding component 2 through multiple sets of branch pipes 10. The main frame 1 has a water inlet 4 at the top and a water outlet 5 at the bottom. Multiple inspection holes 6 are opened on the side walls. Sealing covers are installed on the inspection holes 6 for inspection and maintenance. The support feet 7 are set at the bottom of the main frame 1 and are height adjustable to adapt to different terrain conditions.

[0020] The main frame 1 is internally equipped with a layered flow guiding assembly 2, which includes a first flow guiding plate 8, a second flow guiding plate 9, and an intermediate connector. Both the first and second flow guiding plates 8 and 9 have a wave-shaped structure and are fixedly connected by the intermediate connector to form staggered flow guiding channels. The surface of the first flow guiding plate 8 has multiple flow guiding grooves, the depth of which gradually decreases from the center to both sides, allowing the sewage to be evenly distributed along the flow guiding grooves. The surface of the second flow guiding plate 9 has multiple through holes, the diameter of which gradually increases from the center to the edge to regulate the flow velocity and flow rate of the sewage. The layered flow guiding assembly 2 is fixedly connected to the partition plate by bolts to ensure its stable position and prevent displacement, while ensuring that the sewage can flow along a predetermined path in different functional areas.

[0021] The biomimetic root system structure module 3 consists of a main pipe, branch pipes 10, and adsorption units 11. The main pipe is vertically installed below the layered flow guiding assembly 2, and its two ends are connected to the first flow guiding plate 8 and the second flow guiding plate 9, respectively. The branch pipes 10 extend horizontally from both sides of the main pipe, and the adsorption units 11 are located at their ends. The adsorption units 11 are composed of multiple layers of filter media: the inner layer is activated carbon granules, the middle layer is zeolite granules, and the outer layer is ceramsite granules. The three layers are separated and fixed by a metal mesh. The adsorption units 11 are wrapped with a flexible protective cover 12, which is made of polyurethane material, to protect the adsorption units 11 from external impact damage. The main pipe has a diversion plate inside, which divides the main pipe into multiple independent chambers. Each chamber is connected to the adsorption unit 11 through the branch pipes 10. The surface of the diversion plate has multiple diversion holes, and the diameter of the diversion holes gradually decreases from top to bottom to control the distribution ratio of sewage in the chambers.

[0022] The branch pipe 10 is equipped with spiral blades that are continuously distributed along its axis to increase the flow path of wastewater within the pipe and enhance the contact time between the wastewater and the adsorption unit 11. The spiral blades are coated with a biofilm layer composed of microbial flora to further degrade organic pollutants in the wastewater. The branch pipe 10 is connected to the main pipe via a flange with a sealing ring to prevent leakage. The end of the branch pipe 10 is threadedly connected to the adsorption unit 11 for easy disassembly and replacement.

[0023] The backwashing system is located inside the main frame 1 and includes a backwash pipe 13, nozzles 14, and a control valve 15. The backwash pipe 13 is installed at the top of the main frame 1, with one end connected to an external water source and the other end connected to the stratified flow guide assembly 2 via the nozzles 14. The control valve 15 is located in the middle of the backwash pipe 13 and is used to control the opening and closing of the backwashing system. The number of nozzles 14 matches the number of branch pipes 10, with each nozzle 14 facing the inlet of a branch pipe 10 to remove sediment from the branch pipe 10. A level sensor 16 is located on the side wall of the main frame 1 and is electrically connected to the control valve 15. When the level sensor 16 detects that the liquid level inside the main frame 1 is lower than a set value, the control valve 15 automatically closes to stop the backwashing operation. A control panel is located outside the main frame 1 and is electrically connected to the level sensor 16 and the control valve 15 for real-time monitoring and adjustment of the device's operating status.

[0024] The partition plate has reinforcing ribs on its surface, which are evenly distributed along its length to improve its structural strength and resistance to deformation. Sealing strips made of silicone are provided along the edges of the partition plate to prevent sewage leakage from the gap between the partition plate and the main frame 1. The partition plate is fixedly connected to the main frame 1 by welding or bolts to ensure its stable position and prevent loosening.

[0025] The specific operation process of this device is as follows: Wastewater enters the main frame 1 through inlet 4. It is initially distributed and guided by the first guide plate 8 and the second guide plate 9 of the layered flow guiding assembly 2. The wastewater is evenly distributed along the guide grooves on the surface of the first guide plate 8 and flows into the biomimetic root structure module 3 through the through holes on the second guide plate 9. After entering the biomimetic root structure module 3, the wastewater is distributed to various chambers by the diversion plate inside the main pipe, and then flows to the adsorption unit 11 through the branch pipe 10. In the branch pipe 10, the wastewater is affected by the spiral blades, increasing the flow path length and prolonging the contact time with the adsorption unit 11. The multi-layered filter media inside the adsorption unit 11 removes suspended solids and dissolved pollutants from the wastewater step by step, while the biofilm layer further degrades organic pollutants in the wastewater. The treated wastewater is discharged from the main frame 1 through outlet 5 and enters the subsequent treatment system.

[0026] After the device has been running for a period of time, sediment may accumulate in the branch pipe 10. At this time, the backwashing system is activated, and external water enters the nozzle 14 through the backwash pipe 13. The nozzle 14 sprays water to the inlet of the branch pipe 10, and the water flow impacts the inside of the branch pipe 10, flushing the sediment to the bottom of the main frame 1, and then discharges it through the outlet 5. The liquid level sensor 16 monitors the liquid level in the main frame 1 in real time. When the liquid level is lower than the set value, the control valve 15 automatically closes to stop the backwashing operation. The status of the liquid level sensor 16 and the control valve 15 can be monitored in real time through the control panel, and the operation of the device can be adjusted.

[0027] The support feet 7 at the bottom of the main frame 1 can be adjusted in height according to the actual installation terrain. The adjustment is made by rotating the adjusting nut on the support foot 7 to change its height, thus ensuring the main frame 1 is placed horizontally. The inspection hole 6 facilitates regular cleaning and maintenance of the internal components. Opening the sealing cover on the inspection hole 6 allows access to the main frame 1 for operation. The reinforcing ribs and sealing strips on the partition plate improve the overall structural strength and sealing performance of the device, making it suitable for installation in various terrain conditions, while simplifying the construction process and reducing the difficulty of operation and management. To better enable those skilled in the art to fully understand and implement this utility model, the specific implementation principle of this utility model is further explained below in conjunction with a specific application scenario.

[0028] In practical applications, this biomimetic root-structure soil infiltration purification device can be installed in wastewater treatment plants or ecological restoration projects. For example, if a wastewater treatment plant needs to treat industrial wastewater containing suspended solids and dissolved pollutants, using this device can effectively improve purification efficiency and reduce maintenance costs. The following are supplementary explanations of the specific operating steps and their implementation principles.

[0029] Wastewater first enters the main frame 1 through inlet 4. It then flows through the first guide plate 8 and the second guide plate 9 of the layered flow guiding assembly 2. Multiple guide grooves on the surface of the first guide plate 8 have a depth that gradually decreases from the center to the sides, allowing the wastewater to be evenly distributed along the grooves. This design avoids the localized siltation caused by a single water flow path in traditional devices, ensuring a more uniform distribution of wastewater throughout the entire device. Subsequently, the wastewater flows into the biomimetic root structure module 3 through through holes on the second guide plate 9. The diameter of the through holes on the surface of the second guide plate 9 gradually increases from the center to the edge; this design regulates the flow velocity and flow rate of the wastewater, thereby further optimizing the wastewater flow path.

[0030] When wastewater enters the biomimetic root system module 3, the diversion plate inside the main pipe distributes the wastewater to various independent chambers. The diameter of the multiple diversion holes on the surface of the diversion plate gradually decreases from top to bottom. This design controls the distribution ratio of wastewater within the chambers, avoiding short-circuiting caused by uneven flow. As wastewater flows from the main pipe to the branch pipe 10, the spiral blades inside the branch pipe 10 increase the flow path length of the wastewater and prolong the contact time between the wastewater and the adsorption unit 11. The biofilm layer coated on the surface of the spiral blades is composed of microbial communities, which can further degrade organic pollutants in the wastewater, thereby improving the purification effect.

[0031] The adsorption unit 11 employs a multi-layer filter media structure, with activated carbon granules as the inner layer, zeolite granules as the middle layer, and ceramsite granules as the outer layer. This step-by-step filtration method effectively removes suspended solids and dissolved pollutants from wastewater. Metal mesh separates and fixes the different layers of filter media, ensuring media stability and preventing clogging caused by media mixing. The flexible protective cover 12 encasing the adsorption unit 11 is made of polyurethane, protecting it from external impact damage and extending the device's lifespan.

[0032] After the device has been running for a period of time, sediment may accumulate in the branch pipe 10. At this time, the backwashing system is activated. External water enters the nozzle 14 through the backwash pipe 13. The nozzle 14 sprays water to the inlet of the branch pipe 10. The water flow impacts the inside of the branch pipe 10 and flushes the sediment to the bottom of the main frame 1, where it is then discharged through the outlet 5. The level sensor 16 monitors the liquid level in the main frame 1 in real time. When the liquid level is lower than the set value, the control valve 15 automatically closes to stop the backwashing operation. This design not only ensures the long-term stable operation of the device but also reduces maintenance costs.

[0033] The support feet 7 at the bottom of the main frame 1 can be adjusted in height according to the actual terrain conditions. This adjustment is achieved by rotating the adjusting nuts on the support feet 7 to change their height, thus ensuring the main frame 1 is placed horizontally. The reinforcing ribs on the surface of the partition plate improve its structural strength and resistance to deformation, while the sealing strips at the edges of the partition plate prevent sewage leakage from the gaps between the partition plate and the main frame 1. These designs make the device suitable for installation in various terrain conditions, while simplifying the construction process and reducing the difficulty of operation and management.

[0034] Through the above steps and supplementary explanation of their implementation principles, it can be seen that the design of this utility model not only solves the problems of local siltation, short-flow, and easy clogging existing in traditional soil infiltration devices, but also significantly improves purification efficiency and long-term stability of the device. The entire device operates logically, with each component working in concert to ensure the effectiveness of wastewater purification and the reliability of the device.
