Description

Technical Field

[0001] This application relates to the field of wastewater treatment technology, and in particular to an MRS water purification device. Background Technology

[0002] MRS (Microbial High-Efficiency Water Purification) technology is a novel wastewater treatment process that utilizes a bioreactor system constructed by combining microbial communities with sand to achieve highly efficient purification. Its core advantages include an eco-friendly design, low energy consumption, and ease of maintenance. The treated water meets the national Class A discharge standard. MRS technology uses microbial communities (such as aerobic and anaerobic bacteria) combined with sand to form a multi-layered bioreactor system, decomposing pollutants through microbial metabolism. Simultaneously, it incorporates plant-assisted purification to achieve highly efficient decomposition.

[0003] In related technologies, the provided MRS system has a large number of raw water inlet pipes installed on the filter layer to introduce external sewage into the filter layer. However, the planting layer has a large area, and if only one raw water inlet pipe is introduced, it is difficult to evenly distribute it across the cross-section of the planting layer, which is not conducive to achieving uniform water distribution. If multiple raw water inlet pipes are introduced into the filter layer, although it is conducive to achieving uniform water distribution, the large number of inlet pipes and the need for each inlet pipe to be arranged on the same plane make the overall arrangement difficult and are not conducive to improving the assembly efficiency of the water purification system.

[0004] In view of the above, this utility model is hereby proposed. Utility Model Content

The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] like Figures 1 to 3As shown in the illustration, this application provides an MRS water purification device, including: a tank 1, a planting layer 2, a filter layer 3, a purification layer 4, a water collection layer 5, a distribution box 6, and multiple vertical guide pipes 7. The tank 1 has a cavity and a drain outlet 11 communicating with the cavity, the drain outlet 11 being located at the bottom of the tank 1. The planting layer 2, filter layer 3, purification layer 4, and water collection layer 5 are all disposed within the cavity, and are arranged sequentially from the top to the bottom of the tank 1. The distribution box 6 has a flat structure, and is horizontally disposed within the filter layer 3 near the planting layer 2. The distribution box 6 has a water distribution cavity and multiple hollow grooves, each of the hollow grooves penetrating the distribution box 6 along its thickness direction, and the hollow grooves are isolated from the water distribution cavity. Each of the vertical water guide pipes 7 is connected to the distribution box 6, and the vertical water guide pipes 7 are connected to the water distribution chamber. Each of the vertical water guide plates is evenly distributed in the distribution box 6. The vertical water guide pipes 7 extend along the thickness direction of the filter layer 3, and multiple permeation holes a are provided on the pipe wall of the vertical water guide pipes 7.

[0025] The wastewater inlet pipe 8 passes through the tank 1 and connects to the inlet on the distribution box 6 to inject wastewater into the distribution box 6. The wastewater flows along the water distribution chamber of the distribution box 6 into each vertical guide pipe 7, and then evenly seeps into the filter layer 3 through the permeation holes a on the vertical guide pipe 7, thus achieving uniform water distribution. The wastewater flows from top to bottom through the filter layer 3, the purification layer 4, and the water collection layer 5, and is finally discharged from the drain outlet 11. During this process, the wastewater is gradually purified by the plant-assisted purification and the decomposition of pollutants by the metabolic action of microbial communities (such as aerobic bacteria and anaerobic bacteria).

[0026] This embodiment of the application, by setting multiple perforated grooves on the diversion box 6, avoids the roots of the plants on the planting layer 2, allowing the plant roots to extend into the perforated area and contact the sewage area. The plant roots purify sewage through multiple mechanisms, mainly including absorbing pollutants, enriching heavy metals, promoting microbial degradation, and inhibiting algae growth. The roots can directly absorb nutrients such as nitrogen and phosphorus from the water. The roots have a strong adsorption capacity for heavy metals, fixing them to the root through cell walls and secretions. Root secretions provide carbon sources and oxygen for microorganisms, forming a rhizosphere micro-ecosystem. The plant roots transport oxygen to the root zone, forming an oxidative state on the root surface. Most of the organic matter in the wastewater is decomposed into CO2 and water by aerobic microorganisms in this zone using oxygen as the terminal electron acceptor; ammonia is nitrified by nitrifying bacteria in this zone; in areas farther from the root surface, the oxygen concentration is lower, belonging to a facultative anaerobic zone, where nitrification still occurs, but mainly by denitrifying bacteria to degrade organic matter and release nitrogenous substances into the atmosphere in the form of nitrogen gas. In the reducing state region of the root zone, organic matter is decomposed into CO2 and CH4 and released into the atmosphere through the fermentation of anaerobic bacteria.

[0027] The diversion box 6 of this application has a flat plate structure. The diversion box 6 can be a metal box or a plastic box. The diversion box 6 can be directly laid inside the tank 1, which simplifies the layout and improves assembly efficiency compared to laying water pipes.

[0028] The MRS water purification equipment applied for replaces the traditional water distribution pipeline with a diversion box 6, which simplifies the layout process of the traditional water distribution pipeline, improves the assembly efficiency, and realizes the rapid and uniform distribution of raw water in the filter layer 3. This shortens the sewage treatment cycle and also opens a large number of hollow grooves to reduce the impact on the surface root system of green plants.

[0029] In some possible implementations, such as Figure 2 As shown, the diversion box 6 includes a bottom shell 61 and a top cover 62. The bottom shell 61 has a bottom plate 611 and vertical ribs disposed on the bottom plate 611. A cavity is enclosed between the bottom plate 611 and the vertical ribs. The hollow groove includes a bottom opening 614 disposed on the bottom plate 611 and a top opening 621 disposed on the top cover 62. Each of the vertical water guide pipes 7 is vertically connected to the bottom plate 611. When the top cover 62 is placed on the bottom shell 61, the top cover 62 covers the top opening of the cavity to form the water distribution cavity. The top opening 621, the bottom opening 614 and the vertical ribs between them together constitute the hollow groove.

[0030] The diversion box 6 of this application is formed by the snap-fit ​​of the bottom shell 61 and the top cover 62. When there is dirt in the diversion box 6, the bottom shell 61 and the top cover 62 can be disassembled to facilitate the cleaning of dirt and impurities in the water distribution chamber.

[0031] In some possible implementations, the uprights include edge ribs 612 and internal ribs 613. The edge ribs 612 are disposed on the peripheral edge of the base plate 611, and the internal ribs 613 are disposed on the base plate 611 and located on the peripheral edge of the bottom opening 614. When the upper cover 62 is placed on the bottom shell 61, the upper cover 62 is in sealed contact with the internal ribs 613 and the edge ribs 612.

[0032] It should be noted that the vertical ribs on the upper cover 62 and the bottom shell 61 can be sealed together. Of course, even if the vertical ribs on the upper cover 62 and the bottom shell 61 are not completely sealed together, water distribution can still be normal. That is, the sealing requirements of the vertical ribs on the upper cover 62 and the bottom shell 61 are not high, which simplifies the manufacturing process.

[0033] In some possible implementations, sealing strips 63 are provided along the upper edges of both the internal ribs 613 and the edge ribs. The upper cover 62 and the bottom shell 61 are detachably connected. When the upper cover 62 and the bottom shell 61 are connected, the sealing strips 63 are compressed and deformed and positioned between the upper cover 62 and the bottom shell 61. The sealing strips 63 seal the upper cover 62 from the internal ribs 613 and the edge ribs, minimizing sewage leakage into the diversion box 6. There can be multiple sealing strips 63, all of which are closed annular rings.

[0034] In some possible implementations, multiple smaller seepage holes can be provided on the bottom shell 61 to allow for slight water seepage. The diameter of the seepage holes is much smaller than the inner diameter of the vertical guide pipe, so it will not affect the flow of sewage into the vertical guide pipe.

[0035] In some possible implementations, such as Figure 2 As shown, a plurality of first lugs 615 are provided on the bottom shell 61, and each of the first lugs 615 is arranged sequentially at intervals along the circumference of the bottom shell 61. A plurality of second lugs 622 are provided around the edge of the top cover 62. Each of the first lugs 615 and the corresponding second lug 622 are connected by a connector. The connector may include a bolt and a nut. The bolt passes through the first lug 615 and the second lug 622, and the nut is threaded onto the bolt. The caps at the ends of the nut and the bolt are respectively positioned on the first lug 615 and the second lug 622, thereby fastening the bottom shell 61 and the top cover 62.

[0036] In some possible implementations, such as Figure 1 As shown, the inner wall of the tank 1 is provided with an inner flange 12, and the periphery of the diversion box 6 is supported by the inner flange 12. All the inner flanges 12 are located in the same plane, so that the diversion box 6 can be horizontally supported on each inner flange 12, which is beneficial to the uniform water distribution of the diversion box 6.

[0037] In some possible implementations, the perforated grooves are arranged in multiple rows and columns to form a large area of ​​perforated space, which facilitates the extension of plant roots on the planting layer 2 to the filter layer 3, thereby achieving the effect of root-assisted water purification.

[0038] In some possible implementations, such as Figure 1 and Figure 3 As shown, the vertical water guide pipe 7 includes a first pipe body 71 and a second pipe body 72. The first pipe body 71 is fixedly connected to the diversion box 6. The first pipe body 71 has an external thread 711, and the second pipe body 72 has an internal thread 721, which is threadedly connected to the first pipe body 71. Under the action of external force, the second pipe body 72 can rotate around the first pipe body 71 to adjust the length of the vertical water guide pipe 7. The length of the water guide pipe is adjustable. The second pipe body 72 can be screwed on according to the thickness of the filter layer 3 to adjust the length of the water guide pipe to match the thickness of the filter layer 3.

[0039] In some possible implementations, the planting layer 2 includes multiple planting units 21, each of which is located at the top of a corresponding perforated groove. The cross-section of the perforated groove can be larger than the cross-section of the planting unit 21 to minimize obstruction to root growth and facilitate greater root contact with wastewater.

[0040] In some possible implementations, the MRS water purification device includes a support body 22, with gaps formed between each of the planting units 21, and the support body 22 is embedded within the gaps. The support body 22 serves to support each planting unit 21 and prevent the planting units 21 from spreading out. The support body 22 can be a structure such as soil, sand, concrete, bricks, or plastic sheets. This application does not limit the specific structure of the support body 22. The support body 22 can be formed by assembling multiple small structural blocks, which can enclose multiple areas, with each planting unit 21 placed within a corresponding area.

[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
