Description

Technical Field

[0001] This utility model relates to the field of landfill leachate treatment, and in particular to a landfill leachate treatment device and evaluation equipment. Background Technology

[0002] Municipal solid waste leachate, as wastewater generated during the landfilling and stockpiling of municipal solid waste, is closely related to atmospheric precipitation, the moisture content of the waste itself, and the decomposition of organic matter. This type of wastewater is characterized by high pollution load and complex composition. If it is discharged directly without effective treatment, it can easily cause serious pollution to soil, surface water, and groundwater, posing a potential threat to the ecological environment and human health. Therefore, proper treatment of leachate is crucial, and its core objective is to reduce pollutants such as organic matter, ammonia nitrogen, and inorganic metal salts in the leachate.

[0003] In existing treatment technologies, a relatively mature process has been widely used. First, the leachate is transported to a horizontal flow grit chamber, where gravity causes larger particles of sand and other impurities to settle. Next, the treated leachate is sent to a coagulation sedimentation tank, where coagulants and flocculants are added to cause colloids and fine suspended solids in the water to coagulate into flocs and be removed by sedimentation. Then, the leachate is filtered through a rotary drum filter to further remove suspended solids and colloidal substances. Afterward, the leachate is transported to a sand filter tank, where the filtration effect of filter media such as quartz sand further purifies the water. Following these treatments, the leachate enters a regulating tank to adjust the water quality and quantity, creating stable conditions for subsequent biological treatment and ensuring that the biological treatment can proceed efficiently and stably, thereby achieving effective purification of municipal solid waste leachate.

[0004] As provided in the prior art, a municipal solid waste leachate treatment device includes a sedimentation chamber and a filter assembly at the bottom of a dewatering cylinder. The filter assembly includes a membrane treatment chamber connected to the sedimentation chamber at its bottom via a connecting conduit. One end of the membrane treatment chamber has an outlet at its bottom. An mounting ring is located on the opposite side of the connecting conduit within the membrane treatment chamber, and the mounting ring slides within the membrane treatment chamber. A drive ring is located inside the membrane treatment chamber within the mounting ring, and the drive ring rotates within the mounting ring. A filter membrane roller is horizontally mounted on the end face of the drive ring, and the end of the filter membrane roller has an opening that rotates within the connecting conduit. The mounting ring is located on one side outside the membrane treatment chamber. Equipped with a filter motor, the output end of which is coaxially connected to the drive ring. Pull rings are located on both sides of the filter motor on the end face of the mounting ring. This design solves the problem that traditional filtration-based solid-liquid separation methods cannot effectively separate viscous, gel-like wastewater mixtures or those containing small particles of soil and debris during leachate treatment. This results in smaller particles in the filtered leachate, reducing the likelihood of clogging in subsequent treatment processes and making subsequent treatment more convenient. Furthermore, the filter membrane roller's design allows for easy and quick disassembly and installation while filtering the leachate, making cleaning the filter membrane roller easier and faster.

[0005] However, the existing device has obvious limitations. When the filter membrane roller needs to be cleaned, the staff must disassemble the entire filter membrane roller to carry out the cleaning operation. This process not only consumes a lot of time and manpower and increases maintenance costs, but frequent disassembly may also damage the filter membrane roller, affecting its service life and filtration effect.

[0006] Therefore, it is necessary to provide a municipal solid waste leachate treatment device to solve the above-mentioned technical problems. Utility Model Content

[0041] A rinsing assembly 5 is provided on the outer side of the filter assembly 2. The rinsing assembly 5 includes a moving ring 51 and a nozzle 52.

A water pump 12 is installed on one side of the moving ring 51 through a pipe. The water pump 12 is fixedly installed on the side of the outer casing 1. A scraping assembly 6 is provided inside the filter assembly 2. The scraping assembly 6 includes a moving frame 61, a mounting plate 62, a connecting rod 63, a support frame 64, a scraper 65, and an abutment plate 66. One end of 61 is fixedly installed at both ends of one side of the movable ring 51, the mounting plate 62 is fixedly installed at the other end of the movable frame 61, the connecting rod 63 is fixedly installed at one side of the mounting plate 62, the support frame 64 is fixedly installed at one end of the connecting rod 63, the scraper 65 is fixedly installed at one side of the support frame 64, the abutment plate 66 is rotatably connected to the outer side of the connecting rod 63, and a moving component 4 is provided inside the outer shell 1. The moving component 4 is used to drive the rinsing component 5 to move left and right on the outer side of the filter component 2.

[0042] The filter assembly 2 includes a filter cylinder 21 and two support rings 22. The two support rings 22 are fixedly installed at both ends of the filter cylinder 21. One support ring 22 is rotatably connected to the inside of the other end of the outer shell 1, and one end of the support ring 22 abuts against the side of the abutment plate 66. The inside of one end of the other support ring 22 is rotatably connected to a water inlet pipe 23. The drive assembly 3 includes a first drive member 31, a drive gear 32, and a driven gear 33. The first drive member 31 is fixedly installed on the inner side of the outer shell 1. The drive gear 32 is fixedly installed on the output end of the first drive member 31. The driven gear 33 meshes with the side of the drive gear 32. The driven gear 33 is fixedly installed on the outer side of the other support ring 22.

[0043] The moving component 4 includes a second driving member 41, a threaded rod 42, and a connecting frame 43. The second driving member 41 is fixedly installed at one end of the housing 1. The threaded rod 42 is fixedly installed at the output end of the second driving member 41. The connecting frame 43 is threadedly connected to the outer side of the threaded rod 42. One end of the connecting frame 43 is fixedly installed to the moving ring 51. A baffle plate 13 is provided on one side of the threaded rod 42. The baffle plate 13 is fixedly installed on the inner side of the housing 1.

[0044] The sedimentation assembly 7 includes a sedimentation tank 71, a drain hole 72, a baffle plate 73, and a filter screen 74. The sedimentation tank 71 is fixedly installed on the top of the outer shell 1. The drain hole 72 is opened at the bottom of the sedimentation tank 71, and the bottom of the drain hole 72 penetrates the top of the water inlet pipe 23. The baffle plate 73 is fixedly installed on the inner side of the sedimentation tank 71, and the filter screen 74 is fixedly installed inside the baffle plate 73.

[0045] The first driving component 31 is a motor; there are two support rings 22, one for rotating connection with the outer casing 1, and the other for blocking and installing the driven gear 33. In this way, when in use, the leachate thrown out from inside the filter cartridge 21 will not be directly thrown onto the first driving component 31.

[0046] The second driving component 41 is also a motor. When in use, the rotation of the motor drives the threaded rod 42 to rotate, thereby connecting the threaded rod 42 and the connecting frame 43 by threads. The baffle plate 13 set on the side of the threaded rod 42 can block the leachate and prevent the leachate from being directly thrown onto the threaded rod 42.

[0047] When the rinsing assembly 5 and the scraping assembly 6 move, the moving ring 51 moves to the front end of the scraper 65, so that the filter cartridge 21 is rinsed first and then scraped.

[0048] Furthermore, during normal use, the scraper 65 is positioned on the right side of the water outlet of the inlet pipe 23, thereby preventing impurities from entering the right side of the scraper 65 and increasing the subsequent effect of scraping off impurities inside the filter cartridge 21.

[0049] The filter cartridge 21 is a filter membrane roller, used to filter finer substances in the leachate;

[0050] When the water pump 12 is in use, it can extract the leachate on the inner side of the outer casing 1 and then transport it through the pipeline to the inner side of the moving ring 51. Since the moving ring 51 is hollow, it can divert the water into the interior of multiple nozzles 52 and then spray it out.

[0051] When using sedimentation tank 71, leachate squeezed out from domestic waste is transported to the bottom of sedimentation tank 71 through pipeline. The leachate flows from bottom to top. With the combined action of baffle plate 73 and filter screen 74, larger particles of impurities settle to the bottom of the tank due to gravity; floating objects are intercepted by filter screen 74; and the leachate after preliminary filtration passes through filter screen 74 and enters the subsequent treatment process through drain hole 72.

[0052] The water pump 12, filter assembly 2, drive assembly 3, moving assembly 4, flushing assembly 5, and scraping assembly 6 work together. During use, the moving assembly 4 drives the moving ring 51 and nozzle 52 to move, flushing the filter cylinder 21 from the outside in. At the same time, the scraping assembly 6 moves synchronously with the moving ring 51, and the scraper 65 can scrape off the impurities attached to the inner wall of the filter cylinder 21, allowing the impurities to be discharged smoothly. This saves manpower and time costs for cleaning the filter cylinder 21, reduces the risk of damage to the filter cylinder 21 caused by frequent disassembly, effectively extends the service life of the filter cylinder 21, ensures the filtration effect, and improves the overall operating efficiency and stability of the municipal solid waste leachate treatment device.

[0053] The working principle of the municipal solid waste leachate treatment device provided by this utility model is as follows:

[0054] To prevent impurities in the leachate from affecting subsequent chemical treatment, pretreatment operations of sedimentation and filtration are required. First, the domestic waste is dehydrated by a dewatering device to achieve preliminary solid-liquid separation. Then, the leachate is transported through a pipeline to the bottom of the inner side of the sedimentation tank 71, where larger particles settle on the inner side of the sedimentation tank 71. Excess wastewater is filtered through the filter screen 74 and discharged, thus performing preliminary filtration of the leachate to remove larger particles of impurities and floating matter. The larger particles settle at the bottom of the tank, while the floating matter is blocked on the filter screen 74. The pre-filtered leachate enters the inlet pipe 23 through the drain hole 72.

[0055] The leachate enters the filter cylinder 21 through the inlet pipe 23, and the first drive component 31 is activated. The first drive component 31 drives the drive gear 32 to rotate. The drive gear 32 meshes with the driven gear 33, thereby driving the driven gear 33 to rotate. This causes the support ring 22, which is fixedly connected to the driven gear 33, to drive the filter cylinder 21 to rotate. During the rotation of the filter cylinder 21, solid impurities in the leachate are trapped on the inner wall of the filter cylinder 21, while the liquid permeates through the filter membrane, completing the secondary solid-liquid separation.

[0056] When the filter cartridge 21 needs to be cleaned, the second drive unit 41 is activated, which drives the threaded rod 42 to rotate. The connecting frame 43 is threadedly connected to the threaded rod 42, so the connecting frame 43 will move left and right on the threaded rod 42 as the threaded rod 42 rotates. Since the connecting frame 43 is fixedly installed with the moving ring 51, the moving ring 51 will drive the nozzle 52 to move to one end on the outer side of the filter cartridge 21. At the same time, the water pump 12 is activated, and the water pump 12 delivers water to the nozzle 52 through the pipeline. The nozzle 52 sprays water to rinse the outer side of the filter cartridge 21.

[0057] During the rinsing process, the movement of the moving ring 51 will drive the moving frame 61 to move synchronously. The moving frame 61 will drive the mounting plate 62, connecting rod 63, support frame 64 and scraper 65 to move. During the movement, the scraper 65 will scrape off the impurities attached to the inner wall of the filter cylinder 21. The scraped impurities and the impurities washed off will move with the scraper 65 to one end of the support ring 22 with an opening, and then be discharged through the opening of the support ring 22.

[0058] Then, the filtered leachate located at the bottom of the inner side of the outer shell 1 is transported to the chemical treatment stage through valve 11. Chemical agents are then added to the leachate so that the chemical agents can react precisely with the harmful substances in the leachate, thereby improving the efficiency and effectiveness of subsequent chemical reactions.

[0059] Compared with related technologies, the municipal solid waste leachate treatment device provided by this utility model has the following beneficial effects:

[0060] The structure, consisting of the outer shell 1, filter assembly 2, drive assembly 3, and sedimentation assembly 7, works together to perform preliminary filtration of the leachate during use, removing larger particulate impurities. The filter assembly 2 achieves secondary solid-liquid separation through the rotating filter cylinder 21, trapping solid impurities and allowing liquid to permeate through the filter membrane, effectively improving the purification level of the leachate, providing higher-quality water samples for subsequent chemical treatment, and improving the efficiency and effectiveness of chemical reactions.

[0061] Second Embodiment

[0062] Please refer to the following: Figure 8 , Figure 9 and Figure 10 Based on the first embodiment of this application providing a municipal solid waste leachate treatment device, the second embodiment of this application proposes another municipal solid waste leachate treatment device. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0063] Specifically, the difference in the second embodiment of this application regarding the treatment device for municipal solid waste leachate is that the device further includes an adsorption component 8. The adsorption component 8 is disposed on the inner side of the sedimentation tank 71. The adsorption component 8 includes a support frame 81, a leakage channel 82, a handle 83, and activated carbon 84. The support frame 81 is disposed at the top of the drain hole 72, the leakage channel 82 is opened at the bottom of the support frame 81, the handle 83 is fixedly installed at both ends of the top of the support frame 81, the activated carbon 84 is disposed on the inner side of the support frame 81, and a guide plate 85 is disposed at the top of the support frame 81. One side of the guide plate 85 is fixedly installed with the baffle plate 73.

[0064] The guide plate 85 at the top of the support frame 81 can guide the leachate smoothly into the adsorption area, and the drain trough 82 at the bottom facilitates the discharge of the purified leachate. At the same time, the support frame 81 can be easily disassembled and the activated carbon 84 can be replaced through the handle 83. The operation is simple and convenient, which improves the flexibility of the device and the convenience of maintenance.

[0065] The working principle of the municipal solid waste leachate treatment device provided by this utility model is as follows:

[0066] During operation, the settled leachate enters the inner side of the support frame 81 through the filter screen 74 and the guide plate 85. Due to the abundant pore structure and large specific surface area of ​​the activated carbon 84, it has a strong adsorption capacity for organic matter, some heavy metal ions, and residual microparticle impurities in the leachate. The leachate comes into full contact with the activated carbon 84 within the support frame 81, and the harmful substances are adsorbed and retained by the activated carbon 84, thereby further purifying the leachate. Afterward, the adsorption-purified leachate is discharged from the bottom of the support frame 81 through the drain trough 82, and then enters the inlet pipe 23 through the drain hole 72 to continue the subsequent treatment process.

[0067] Compared with related technologies, the municipal solid waste leachate treatment device provided by this utility model has the following beneficial effects:

[0068] By setting up the adsorption component 8, the treatment effect of municipal solid waste leachate is further improved during use. Activated carbon 84 adsorbs harmful substances such as residual organic matter and heavy metal ions in the leachate, making up for the shortcomings of simple sedimentation and filtration. This makes the treated leachate cleaner, reduces the pressure on subsequent treatment processes, and reduces the potential pollution risk to the environment.

[0069] A device for assessing leachate from municipal solid waste.

[0070] Please see Figure 11 and Figure 12 The equipment for assessing municipal solid waste leachate is used to detect and evaluate the treatment status of municipal solid waste leachate after it has been treated by a municipal solid waste leachate treatment device.

[0071] The equipment for assessing leachate from municipal solid waste includes: a protective frame 91, a door 91 rotatably connected to the front of the protective frame 91, a connecting block 92 fixedly installed at the bottom of the protective frame 91, connecting pipes 93 fixedly installed on both sides of the connecting block 92, an installation pipe 94 fixedly installed inside the bottom of the protective frame 91, a detection probe 96 threadedly connected inside the installation pipe 94, a detector 95 mounted on the top of the detection probe 96, a snap-fit ​​frame 90 fixedly installed on the top of the detector 95, a snap-fit ​​strip 99 slidably connected to the inner side of the snap-fit ​​frame 90, the snap-fit ​​strip 99 fixedly installed on the top of the inner side of the protective frame 91, a collar 97 sleeved on the outer side of the installation pipe 94, and a sealing cap 98 fixedly installed on one side of the collar 97.

[0072] When in use, connect one end of the connecting pipe 93 to the output end of the valve 11. When it is necessary to test the discharged leachate, the operator can first close the valve 11, then snap the snap-fit ​​frame 90 onto the outer side of the snap-fit ​​strip 99 to install the detector 95. After that, remove the sealing cover 98 from the outer side of the mounting pipe 94, then thread the detection probe 96 onto the inner side of the mounting pipe 94. Then open the valve 11 to allow the leachate to flow through the connecting pipe 93 and the connecting block 92 and the detection probe 96, so that the detection probe 96 can test the leachate.

[0073] The detector 95 is an online TOC analyzer. It converts organic carbon in water samples into carbon dioxide through high-temperature catalytic oxidation or wet oxidation. Then, it uses non-dispersive infrared absorption and conductivity methods to detect the carbon dioxide content, thereby obtaining the total organic carbon content of the water sample. When the adsorption capacity of activated carbon 84 decreases, the organic matter in the treated wastewater increases, and the TOC value will rise. At this time, the staff needs to replace the activated carbon 84 in a timely manner. In this way, the detector 95 can be used to detect the wastewater and evaluate the adsorption capacity of activated carbon 84.

[0074] Since both the detector 95 and the detector probe 96 are detachable, the staff can disassemble the detector 95 and the detector probe 96 after the test is completed.

[0075] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
