Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of water purification, and in particular relates to a high-load denitrification device composed of MCHS combined with basalt filler. Background Art
[0002] Denitrification microbial nests are an advanced wastewater treatment technology that utilizes microorganisms to reduce NO₃⁻ to N₂, removing nitrate nitrogen from wastewater. MCHS (Multi-directional Catalytic Bioreactors with High-Order Microorganisms) utilizes a high-order bacterial community, basalt fillers, and aerators. The MCHS seed strains are highly effective at degrading organic pollutants in wastewater. MCHS bioreactors or reaction tanks constructed using MCHS technology can remove 50%-90% of COD and 35%-40% of total nitrogen, eliminating microbial toxicity in wastewater and ensuring the stable operation of subsequent conventional activated sludge systems.
[0003] During the conversion of nitrogen in wastewater by MCHS combined with basalt filler, metabolic products of higher-order bacterial species may adhere to the surface of the basalt filler, forming a biofilm. While this biofilm may shed spontaneously over time, it generally does so slowly. Furthermore, due to its adsorption capacity, it can absorb suspended matter in the water. After absorbing suspended matter, this slowly shed biofilm may coat the MCHS combined with basalt filler, potentially hindering effective contact between nitrogen in the wastewater and the bacteria, preventing effective nitrogen removal and impacting treatment effectiveness.
[0004] The existing technology usually uses a special scraper or brush to manually or mechanically scrape off the biofilm that has not fallen off in time at regular intervals. When manually or mechanically scraping the biofilm, if the scraping force is too small, the biofilm cannot be removed. If the force is too large, the bacteria on the denitrification microbial nest may fall off, affecting the denitrification effect of the bacteria. The force is difficult to control, resulting in poor biofilm removal effect. In addition, since the denitrification microbial nest needs to be regularly removed when scraping the biofilm, a large investment of material and financial resources is required, which is not conducive to enterprise cost control.
[0005] Therefore, in response to the above technical problems, it is necessary to provide a high-load denitrification device composed of MCHS combined with basalt filler. Utility Model Content

Specific implementation
[0029] In order to make the person skilled in the art better understand the technical scheme in the utility model, the technical scheme in the embodiment of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiment of the utility model, obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor should belong to the protection scope of the utility model.
[0030] As Figures 1 to 5 shown, a high-load denitrification device combined with MCHS and basalt filler in an embodiment of the utility model, including denitrification tank 2, the operation window 201 is set up on denitrification tank 2, the inlet pipe 1 is fixedly connected on denitrification tank 2, the drain pipe 5 is communicated with on one side of denitrification tank 2, and the one-way valve is installed on the drain pipe 5. The sewage to be purified is sent into denitrification tank 2 by inlet pipe 1, and the high-order bacterial flora and bacterial species on the denitrification microbial nest 302 in denitrification tank 2 are used to carry out denitrification on the sewage, and the water after denitrification is discharged from the drain pipe 5 by opening the one-way valve.
[0031] As Figures 1 to 5As shown, since the bacteria will continue to produce biofilm during the denitrification process, an oscillating component 4 is fixedly connected to the denitrification box 2. The oscillating component 4 includes a motor 401, and a cam 402 is fixedly connected to the output end of the motor 401. A water purification component 3 that matches the oscillating component 4 is installed in the denitrification box 2. The water purification component 3 includes a support member 301, and a plurality of denitrifying microbial nests 302 are installed at the bottom of the support member 301. When the motor 401 is started, it drives the cam 402 to rotate and beat the water purification component 3. The support member 301 is repeatedly beaten by the oscillation component 4, so that the support member 301 is deformed. When the cam 402 is disconnected from the support member 301, the elastic support member 301 can be reset to drive the denitrification microbial nest 302 to vibrate, thereby shaking off the continuously produced biofilm, and avoiding as much as possible that the biofilm that fails to fall off in time absorbs suspended matter and affects the full contact between the bacteria on the denitrification microbial nest 302 and the nitrogen in the water, thereby affecting the wastewater treatment effect. The vibrated biofilm is fully in contact with and adsorbs the suspended matter in the water during the sedimentation process, which improves the adsorption effect to a certain extent. Compared with scraping the biofilm with a brush and a scraper, the bacteria on the denitrification microbial nest 302 are not scratched during the vibration process, and it is not easy to cause the bacteria to fall off, thereby having a negative impact on the denitrification of the incoming water. The water where denitrification is completed is discharged from the drain pipe 5.
[0032] Specifically, the motor 401 is electrically connected to an external power source, and the motor 401 is a waterproof motor, which is common knowledge to those skilled in the art and will not be described in detail.
[0033] like Figure 2 As shown, a drainage mechanism 6 is installed at the bottom of the denitrification tank 2. Initially, drainage mechanism 6 is positioned at the far left side of the denitrification tank 2. Drainage mechanism 6 mates with the oscillating component 4 and includes a pusher block 601 and an auxiliary mechanism for moving pusher block 601. By moving pusher block 601, the operator collects the biofilm removed by vibration, facilitating the removal of the biofilm from the water inlet pipe 1.
[0034] like Figures 2 to 7 As shown, the auxiliary mechanism includes a pair of chutes 604, on which are mounted a limit assembly for limiting the sliding path of a slider 602. The chutes 604 are provided on the inner wall of the denitrification box 2, and a slider 602 is slidably connected within the chutes 604. The sliders 602 are symmetrically fixedly connected to both sides of the dirt-pushing block 601. A movable rope 603 is fixedly connected to both sides of the dirt-pushing block 601. The movable rope 603 passes through the operating window 201 and is slidably connected to the inner wall of the denitrification box 2. The staff pulls the movable rope 603 through the operating window 201 to adjust the position of the dirt-pushing block 601. As the dirt-pushing block 601 moves to the right along the chutes 604, it pushes the biofilm fragments, concentrating the biofilm fragments at the bottom of the denitrification box 2, making it easier for the staff to centrally clear the biofilm out of the denitrification box 2.
[0035] Specifically, the slide 604 is a ring consisting of an upper and lower part. When the dirt pushing block 601 needs to be pulled back to the leftmost position to continue cleaning the biofilm, the dirt pushing block 601 slides in the upper part, which is farther away from the bottom of the denitrification box 2 than sliding in the lower part of the slide 604. This avoids the bottom of the dirt pushing block 601 from contacting the bottom of the denitrification box 2 during the return process as much as possible, pushing the continuously falling biofilm to a position away from the dirt collecting component 8, affecting the collection effect of the biofilm.
[0036] like Figure 2 、 Figure 4 、 Figure 7 As shown, the limiting assembly includes an auxiliary piece 6051, which is hinged in the denitrification box 2. A limiting groove 6052 is provided on one side of the auxiliary piece 6051 for limiting the swing of the auxiliary piece 6051. The limiting groove 6052 is provided on the denitrification box 2. When it is necessary to pull the dirt pushing block 601 back to the leftmost position, the limiting groove 6052 limits the position of the auxiliary piece 6051 so that the auxiliary piece 6051 cannot swing to the left. That is, the auxiliary piece 6051 tilted to the right supports the slider 602 so that the slider 602 returns to the leftmost position along the upper slide groove 604, thereby avoiding as much as possible the pushing of the biofilm fragments at the bottom of the denitrification box 2 during the leftward movement of the dirt pushing block 601, and concentrating the biofilm fragments to the left.
[0037] like Figure 1 As shown, a pollutant collection assembly 8 is connected to one side of the denitrification tank 2. This assembly collects the biofilm produced within the biofilm denitrification tank 2. The pollutant collection assembly 8 comprises a first pollutant collection tank 801, within which a second pollutant collection tank 804 is slidably connected, matching the pollutant discharge mechanism 6. A pollutant pusher 601 pushes scraped biofilm fragments into the second pollutant collection tank 804 for collection, somewhat reducing the workload of post-discharge filtration. A latching assembly is provided on the first pollutant collection tank 801 to control the opening and closing of the second pollutant collection tank 804.
[0038] like Figure 1 、 Figure 6 As shown, the locking assembly includes a pair of connecting slots 802 provided on the first waste collection box 801. A baffle 803 is rotatably connected within the connecting slots 802 and matches the second waste collection box 804. When biofilm fragments need to be processed, the baffle 803 is rotated to release the second waste collection box 804 from its restraint, and the second waste collection box 804 is pulled out to empty the biofilm fragments inside.
[0039] like Figure 6As shown, the bottom of the second sewage collecting tank 804 is provided with multiple groups of filter holes 805. The filter holes 805 allow the staff to filter out the water mixed with biofilm fragments in the second sewage collecting tank 804 when pulling out the second sewage collecting tank 804, thereby reducing waste and preventing nitrogen-containing sewage from dripping to the outside and affecting the environment as much as possible.
[0040] like Figure 2 、 Figure 6 As shown, the denitrification box 2 is equipped with a partition assembly 7 that matches the sewage discharge mechanism 6. The partition assembly 7 includes a partition plate 701 that matches the sewage pusher 601. The partition plate 701 is slidably connected to the denitrification box 2, and a connecting frame 702 is fixedly connected to the partition plate 701. The partition plate 701 can seal the denitrification box 2 to prevent the water in the denitrification box 2 from leaking from the partition plate 701 when the staff cleans the biofilm in the second sewage collection tank 804. The denitrification box 2 is equipped with a locking assembly that matches the connecting frame 702. The locking assembly includes a block 703, and a rotating connector is installed between the block 703 and the denitrification box 2. Rotate the blocking block 703 and move the partition plate 701 upwards through the connecting frame 702. When the dirt pushing block 601 is located closest to the partition plate 701, press the partition plate 701 downwards. The partition plate 701 slides along one side of the dirt pushing block 601 to scrape off the biofilm fragments and push the dirt pushing block 601 back into the denitrification box 2 at the same time, so that the staff can apply a pulling force in the opposite direction to the dirt pushing block 601 through the moving rope 603, and smoothly pull the dirt pushing block 601 back to its initial position.
[0041] Optionally, the push block 601 is provided with a plurality of filter holes to prevent the biofilm from flowing away from the sides and top of the push block 601 as much as possible during the process of pushing the biofilm toward the collection assembly 8, so that the biofilm cannot be better collected. In particular, the side of the partition plate 701 close to the denitrification tank 2 and the side of the first collection tank 801 close to the second collection tank 804 are both installed with rubber gaskets for sealing (not shown in the figure).
[0042] like Figure 2 As shown, the support member 301 is a mesh metal structure. The elasticity of the mesh metal structure allows the vibration of the support member 301 to be more consistent and continuous, which is conducive to timely exfoliation of the biofilm. This minimizes the negative impact of the biofilm on denitrification caused by the biofilm not being shed in time, which may cause the biofilm to thicken after absorbing suspended matter and affect the full contact between the denitrification microbial nest 302 and the nitrogen in the water.
[0043] During use, the motor 401 is started, and the motor 401 drives the cam 402 to rotate, and the wastewater to be denitrified and purified is sent to the denitrification box 2. The cam 402 rotates and repeatedly hits the support member 301, and the support member 301 drives the denitrification microbial nest 302 to vibrate and shake off the biofilm generated during the denitrification process of the denitrification microbial nest 302, so as to avoid as much as possible the biofilm that fails to fall off in time during the denitrification process, and after adsorbing suspended matter, affects the contact between the denitrification microbial nest 302 and nitrogen, thereby gradually affecting the wastewater treatment efficiency. When denitrification is completed and the biofilm fragments that have been shaken off need to be processed, the staff operates the auxiliary mechanism through the operation window 201 to drive the push block 601 to move and collect the biofilm fragments. When the push block 601 pushes the biofilm to the partition plate 701, the partition plate 701 is lifted up and the moving rope 603 is continued to be pulled until the push block 601 is located at the far right. The partition plate 701 is moved down and the partition plate 701 scrapes the biofilm accumulated on one side of the push block 601 into the second sewage collecting box 804. The partition plate 701 is then lowered and closed by rotating the block 703 to prevent water from flowing out of the partition plate 701. The biofilm fragments in the second sewage collecting box 804 can then be cleaned.
