Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and more specifically, to a novel soil membrane water purification device. Background Technology

[0002] Landscape water treatment aims to purify lakes, artificial water features, and other water bodies through physical, chemical, and biological technologies, maintaining clear water quality and ecological balance, and enhancing the aesthetic appeal and environmental quality. Rural wastewater treatment targets rural domestic sewage and livestock wastewater, employing decentralized or centralized treatment models, and selecting processes such as ecological wetlands and biological filters according to local conditions to improve the rural living environment and contribute to the construction of beautiful villages. (This applies to both landscape water treatment and rural wastewater treatment.)

[0003] Currently, constructed wetland technology is commonly used for rural sewage treatment and landscape water treatment. However, this method requires a large area and, due to the need for sufficient reaction time in the filter layer, continuous water intake is not possible, requiring intermittent intake. This limitation on water volume negatively impacts the efficiency of sewage treatment. Therefore, we propose a novel soil membrane water purification system. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a new type of soil membrane water purification equipment to solve the technical problem that the filter layer needs sufficient reaction time in the current sewage treatment, which leads to the inability to continuously process water and affects the sewage treatment efficiency.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a novel soil membrane water purification device, comprising a filter box and an aeration mechanism disposed within the filter box. The upper end of the filter box is open. A water distribution pipe and a water collection pipe are disposed within the filter box. A filter media layer is disposed within the filter box to fill the water distribution pipe and the water collection pipe. The aeration mechanism includes an aeration pipe disposed within the filter box. The starting end of the aeration pipe extends out of the filter box and is provided with an aeration connection flange. Aeration heads are equidistantly disposed on the aeration pipe.

[0006] Preferably, the filter media layer comprises, from top to bottom, top-planting soil, a quartz sand layer, a gravel layer, a MABR membrane module, a microbial layer, a biochar layer, a multi-media filter soil, a filter cloth layer, a quartz sand layer, and a gravel layer, wherein low-rooted shrubs are planted in the top-planting soil.

[0007] Preferably, the water distribution pipe is located inside the quartz sand, and the filter box at the extension of the water distribution pipe is equipped with an inlet connection flange. The water collection pipe is located inside the gravel layer, and the filter box at the extension of the water collection pipe is equipped with an outlet connection flange. Circular holes are provided at a 45-degree angle downwards on both sides of the water distribution pipe and the water collection pipe.

[0008] Preferably, the aeration pipe is located in the quartz sand layer above the water collection pipe. The aeration pipe includes a straight pipe section, a curved section, and a connecting section. The straight pipe section is the two ends of the aeration pipe. Several curved sections are provided. The curved sections are arranged in a double-bend configuration. The curved sections are S-shaped. The connecting section connects the ends of adjacent curved sections.

[0009] Preferably, an air outlet is provided at the connection between the aeration head and the aeration pipe, and an air outlet baffle and a telescopic sleeve are symmetrically installed inside the aeration head. The air outlet baffle is located above the air outlet and has an aeration hole.

[0010] Preferably, a spring is installed inside the telescopic sleeve, and an anti-clogging plate is installed at the end of the spring. The anti-clogging plate includes a blocking part, a telescopic part, a closing part, and a pushing part. The blocking part, telescopic part, and closing part are distributed in a T-shape. The telescopic part is located inside the telescopic sleeve and connected to the spring. The blocking part is attached to the upper end of the air outlet baffle. The front end of the blocking part is set at an acute angle. The blocking part, telescopic part, and closing part close the space above the air outlet. The pushing part is bent upward at 45 degrees and is set at the end of the closing part.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model designs an aeration pipe structure with an S-shaped bend in the aeration pipe and a connecting part that links adjacent bends end to end. This design allows the aeration pipes to be distributed throughout the filter box, providing oxygen evenly to the filter media layer during aeration. Sufficient oxygen provides a good living and metabolic environment for aerobic microorganisms such as nitrifying bacteria in the filter media layer, maintaining the normal metabolism and growth of microorganisms, enabling them to continuously and efficiently decompose pollutants in wastewater, promoting the stable operation of the entire microbial ecosystem, and continuously ensuring the filtration effect of the filter media layer. With the addition of multi-layer filter media, it can support continuous wastewater treatment, improving the effect and efficiency of wastewater treatment. This solves the current problem in wastewater treatment where the filter layer requires sufficient reaction time, resulting in the inability to continuously process wastewater and affecting wastewater treatment efficiency.

[0013] 2. This utility model also achieves multiple purification methods for wastewater through the design of the filter media layer structure. The multi-layer filter media design realizes the purification treatment of wastewater through physical, chemical and biological means. From the initial physical filtration of gravel layer and quartz sand layer, to the adsorption of multi-media filter soil and biochar layer, to the biodecomposition of biological bacteria layer and the enhanced degradation of MABR membrane module, and finally the deep purification of dwarf shrubs in the cultivated soil, it can effectively remove suspended solids, organic matter, heavy metal ions, nitrogen and phosphorus and other nutrients in wastewater, realize the deep purification of wastewater, and make the wastewater treatment effect better.

[0014] 3. This utility model also features an aeration head structure with a spring and an anti-clogging plate inside. When aeration is not in progress, the anti-clogging plate closes the aeration holes of the air outlet baffle and the upper end of the aeration head to prevent filter media from clogging. When aeration occurs, the increased air pressure pushes the anti-clogging plate to contract, opening the aeration holes for aeration. This design effectively prevents the aeration head from being clogged by the filter media, ensuring the normal operation of the aeration system and thus guaranteeing that the equipment can continuously and stably treat wastewater, reducing the frequency and cost of equipment maintenance.

Detailed Implementation

[0024] like Figures 1 to 8As shown, this utility model relates to a novel soil membrane water purification device, including a filter box 101 and an aeration mechanism 200 disposed within the filter box 101. The upper end of the filter box 101 is open. A water distribution pipe 102 and a water collection pipe 103 are disposed within the filter box 101. A filter media layer 104 is disposed within the filter box 101 to fill the water distribution pipe 102 and the water collection pipe 103. The aeration mechanism 200 includes an aeration pipe 201 disposed within the filter box 101. The starting end of the aeration pipe 201 extends out of the filter box 101 and is provided with an aeration connection flange 2011. Aeration heads 202 are equidistantly disposed on the aeration pipe 201. This invention can uniformly supply oxygen to the filter media layer 104. Sufficient oxygen provides a good living and metabolic environment for aerobic microorganisms such as nitrifying bacteria in the filter media layer 104, maintaining the normal metabolism and growth of microorganisms, enabling them to continuously and efficiently decompose pollutants in wastewater, promoting the stable operation of the entire microbial ecosystem, and continuously ensuring the filtration effect of the filter media layer 104. With the multi-layer filter media setup, it can support continuous wastewater treatment, improving the effect and efficiency of wastewater treatment.

[0025] Specifically, the filter media layer 104, from top to bottom, includes topsoil, a quartz sand layer, a gravel layer, a MABR membrane module, a microbial layer, a biochar layer, a multi-media filter soil, a filter cloth layer, another quartz sand layer, and a gravel layer. Low-rooted shrubs 105 are planted within the topsoil. After entering, wastewater undergoes decomposition and adsorption through the quartz sand layer, gravel layer, MABR membrane module, microbial layer, biochar layer, multi-media filter soil, filter cloth layer, quartz sand layer, and gravel layer, and finally exits through the collection pipe 103, meeting discharge standards.

[0026] Furthermore, the water distribution pipe 102 is located within the quartz sand, and the filter box 101 at the extension of the water distribution pipe 102 is equipped with an inlet connection flange 1021. The water collection pipe 103 is located within the gravel layer, and the filter box 101 at the extension of the water collection pipe 103 is equipped with an outlet connection flange 1031. Both ends of the water distribution pipe 102 and the water collection pipe 103 are provided with round holes at a 45-degree downward angle. The water distribution pipe 102 can evenly distribute sewage into the filter box 101, facilitating the filtration work of the filter media and improving the efficiency of sewage treatment. The water collection pipe 103 can discharge the filtered sewage.

[0027] It is worth noting that the aeration pipe 201 is located in the quartz sand layer above the water collection pipe 103. The aeration pipe 201 includes a straight pipe section 2012, a curved section 2013, and a connecting section 2014. The straight pipe section 2012 forms both ends of the aeration pipe 201. Several curved sections 2013 are provided, each with a double bend and an S-shape. The connecting section 2014 connects adjacent curved sections 2013 end to end. During aeration, the aeration pipe 201 is connected to an external aerator. The S-shaped curved section 2013 of the aeration pipe 201 allows the aeration pipe 201 to be distributed throughout the filter box 101, ensuring uniform aeration. Aeration provides oxygen to the nitrifying bacteria in the filter media layer 104. The nitrifying bacteria attach to the soil and MABR membrane, naturally forming a microbial ecosystem conducive to wastewater treatment, which can rapidly decompose pollutants in the wastewater.

[0028] It is worth mentioning that an air outlet 2021 is provided at the connection between the aeration head 202 and the aeration pipe 201. An air outlet baffle 203 and a telescopic sleeve 204 are symmetrically installed inside the aeration head 202. The air outlet baffle 203 is located above the air outlet 2021 and has aeration holes. During aeration, gas is discharged from the air outlet 2021 into the aeration head 202, and then discharged into the filter media layer 104 through the aeration holes of the air outlet baffle 203.

[0029] It is worth noting that a spring 205 is installed inside the telescopic sleeve 204, and an anti-clogging plate 206 is installed at the end of the spring 205. The anti-clogging plate 206 includes a blocking part 2061, a telescopic part 2062, a closing part 2063, and a pushing part 2064. The blocking part 2061, the telescopic part 2062, and the closing part 2063 are arranged in a T-shape. The telescopic part 2062 is located inside the telescopic sleeve 204 and connected to the spring 205. The blocking part 2061 is attached to the upper end of the air outlet baffle 203. The front end of the blocking part 2061 is set at an acute angle. The blocking part 2061, the telescopic part 2062, and the closing part 2063 close the space above the air outlet 2021. The pushing part 2064 is bent upward at a 45-degree angle and is set at the end of the closing part 2063. The spring 205 restricts the position of the anti-clogging plate 206. When aeration is not performed, the blocking part 2061 can close the aeration holes of the air outlet baffle 203 to prevent the filter media from clogging the aeration holes. The telescopic part 2062 and the blocking part 2061 close the upper end of the aeration head 202 to prevent the filter media from clogging the aeration head 202. The closing part 2063 can close the space above the air outlet 2021. When aeration is performed, the air pressure in the space above the air outlet 2021 increases, which can push the obliquely arranged pushing part 2064, thereby causing the anti-clogging plate 206 to retract into the telescopic sleeve 204, which can open the aeration holes on the air outlet baffle 203 to perform aeration.

[0030] Working Principle: This embodiment provides a novel soil membrane water purification device. During use, wastewater, driven by a booster pump, enters the device through the inlet flange 1021 of the distribution pipe 102. Three distribution pipes 102 are placed within a quartz sand layer, with circular holes at a 45-degree angle on both sides. The pressure and angle of the water flow ensure even distribution of the wastewater within the filter box 101, allowing for full contact with the filter media layer 104. Under gravity, the wastewater passes through each part of the filter media layer 104 from top to bottom. First, the gravel layer and quartz sand layer, with their larger particle gaps and rough surfaces, intercept and filter large suspended solids, silt, and other impurities in the wastewater, achieving preliminary physical purification. The filter cloth layer further intercepts smaller particles. The wastewater undergoes several steps to further enhance its cleanliness. First, it enters a multi-media filter layer and a biochar layer. These filter media, relying on their adsorption properties, adsorb organic matter, heavy metal ions, and other pollutants, reducing their concentration. The abundant microorganisms in the bio-layer, under suitable environmental conditions, absorb and metabolize the organic pollutants in the wastewater as nutrients, decomposing them into harmless substances such as carbon dioxide and water through biochemical reactions. The MABR membrane module utilizes the membrane's high-efficiency mass transfer characteristics to ensure full contact between pollutants in the wastewater and the microorganisms attached to the membrane surface, further enhancing the degradation and removal of pollutants. Finally, the top layer of cultivated soil contains dwarf shrubs (105), whose root systems not only stabilize the soil... The soil structure allows for deep purification of wastewater by absorbing nutrients such as nitrogen and phosphorus. Simultaneously, plant transpiration aids in water circulation and utilization. During wastewater treatment, an external aerator is connected to the aeration pipe 201 via an aeration connection flange 2011. When the aerator is turned on, air is transported along the aeration pipe 201 to the filter box 101. The straight section 2012, the curved section 2013, and the connecting section 2014 of the aeration pipe 201 work together to ensure even air distribution within the quartz sand layer above the water collection pipe 103. The aeration head 202 plays a crucial role in this process. When aeration is not in operation, the anti-clogging plate 206, under the elastic force of the spring 205, has its blocking part 2061 tightly fitted against the air outlet baffle 203. At the top, the aeration holes are completely sealed. Simultaneously, the telescopic part 2062 and the closing part 2063 work together to close the space above the air outlet 2021, effectively preventing filter media particles from entering the aeration head 202 and causing blockage. When aeration begins, air enters the aeration head 202 from the aeration pipe 201 through the air outlet 2021. As the air pressure above the air outlet 2021 gradually increases, the pushing part 2064 experiences upward pressure, causing the anti-clogging plate 206 to overcome the elasticity of the spring 205 and retract into the telescopic sleeve 204. This opens the aeration holes on the air outlet baffle 203, allowing air to be smoothly discharged and diffused into the filter media layer 104. Sufficient oxygen provides a favorable environment for the survival and metabolism of nitrifying bacteria and other aerobic microorganisms in the filter media layer 104.These microorganisms can gradually oxidize nitrogenous pollutants such as ammonia nitrogen in wastewater into nitrite, and then into nitrate, effectively removing nitrogenous pollutants from the wastewater. This also promotes the stable operation of the entire microbial ecosystem. Sufficient oxygen maintains the normal metabolism and growth of the microorganisms, enabling them to continuously and efficiently decompose pollutants in the wastewater, ensuring the stability and continuity of the wastewater treatment process. This supports continuous influent treatment. After the synergistic filtration, decomposition, and adsorption of each part of the filter media layer 104, the purified water flows downwards under gravity and enters the water collection pipe 103 through the circular holes set at a 45-degree angle on both sides. The water collection pipe 103 collects the purified water and discharges it from the equipment, ultimately achieving the standard discharge of wastewater and completing the entire wastewater treatment process.
