Abstract
Description
Technical Field
[0001] This utility model relates to the field of landfill leachate treatment technology, and in particular to landfill leachate treatment equipment. Background Technology
[0002] Landfill leachate treatment equipment is a complete set of equipment specifically designed to treat leachate generated during the dumping, landfilling, or incineration of waste. Its core function is to remove pollutants from the leachate through a series of physical, chemical, and biological processes, ensuring that the treated water meets relevant discharge standards or reuse requirements, thereby preventing leachate from polluting soil, groundwater, and surface water.
[0003] In existing technologies, sludge generated at each stage, such as biological sludge, sedimented sludge, and concentrated liquid from membrane separation, is treated to avoid secondary pollution. However, one of the core functions of some biogas digesters is to collect biogas produced by the decomposition of organic matter, whose main components are methane and carbon dioxide. If not sealed, the generated biogas will leak directly into the atmosphere through gaps, making it impossible to collect and utilize effectively. Utility Model Content
[0004] The purpose of this invention is to isolate the outside air, especially oxygen, from entering the pool, thereby preventing oxygen from inhibiting the metabolic activities of anaerobic bacteria, ensuring the stable decomposition of organic matter, and thus increasing biogas production. This provides a landfill leachate treatment device that solves the problem of not only wasting recyclable energy, such as biogas which can be used for power generation and heating, but also increasing the energy consumption cost of the treatment system.
[0005] This utility model also provides a landfill leachate treatment device, including a base, a biogas digester fixedly connected to the top of the base, a plurality of racks fixedly connected inside the biogas digester, a first gear meshing inside the racks, a first drive rod fixedly connected inside the first gear, a first motor fixedly connected to the output end of the first drive rod, a connecting rod rotatably connected to the outside of the first drive rod, and a top cover rotatably connected to the outside of the connecting rod.
[0006] According to the landfill leachate treatment equipment of this utility model, a bracket is fixedly connected to the top of the base, and a fixing plate is fixedly connected inside the bracket.
[0007] According to the landfill leachate treatment equipment of this utility model, a tank is fixedly connected inside the fixed plate, a discharge pipe is fixedly connected outside the tank, and a vent pipe is fixedly connected outside the tank.
[0008] According to the landfill leachate treatment equipment of this utility model, an air pump is fixedly connected to the outside of the vent pipe, and one end of the vent pipe is fixedly connected to the outside of the biogas digester.
[0009] According to the landfill leachate treatment equipment of this utility model, an incubator is fixedly connected to the top of the tank, and a port is fixedly connected to the top of the incubator.
[0010] According to the landfill leachate treatment equipment of this utility model, a second motor is fixedly connected to the top of the incubator, a second drive rod is rotatably connected to the output end of the second motor, and a second gear is fixedly connected to the outside of the second drive rod.
[0011] According to the landfill leachate treatment equipment of this utility model, the second gear is externally meshed with a third gear, the third gear is internally fixedly connected with a rotating rod, and the second drive rod is externally fixedly connected with multiple stirring rods.
[0012] According to the landfill leachate treatment equipment of this utility model, a filter plate is fixedly connected inside the incubator, a limit plate is slidably connected inside the incubator, and an electric push rod is fixedly connected outside the limit plate.
[0013] Beneficial effects:
[0014] 1. In the leachate treatment equipment of this technical solution, the biogas generated after the garbage enters the tank is pumped into the biogas digester through the ventilation pipe by the gas extractor. Driven by the first motor and the first drive rod, the first gear on the outside rotates. The first gear moves under the action of the external rack, thereby the first drive rod drives the external connecting rod to move. The connecting rod drives the external top cover to move, sealing the biogas digester. This isolates the digester from outside air, especially oxygen, preventing oxygen from inhibiting the metabolic activity of anaerobic bacteria, ensuring the stable decomposition of organic matter, and thus increasing biogas production.
[0015] 2. The waste is poured into the incubator from the port. Driven by the second motor and the second drive rod, the external second gear rotates. The second gear drives the external third gear, which in turn drives the internal rotating rod. This rotating rod, along with the second drive rod, drives the external stirring rod to rotate, stirring the waste. The waste is then separated from the waste by a filter plate. After a period of settling, biochemical bacteria are generated. Subsequently, driven by an electric push rod, the limiting plate moves, allowing the biochemical bacteria to enter the tank through the holes. In this way, the self-made biochemical bacteria can be acclimatized to the harsh environment of the leachate, resulting in a stronger degradation ability for target pollutants compared to commercially available general-purpose bacteria.

[0025] Specifically, driven by the first motor 11, the first drive rod 10 drives the external first gear 9 to rotate. The first gear 9 moves under the action of the external rack 8, thereby driving the external connecting rod 12 to move, and the connecting rod 12 drives the external top cover 13 to move.
[0026] A bracket 2 is fixedly connected to the top of the base 1, and a fixing plate 3 is fixedly connected inside the bracket 2.
[0027] The tank 4 is fixedly connected inside the fixed plate 3, the discharge pipe 14 is fixedly connected outside the tank 4, and the vent pipe 5 is fixedly connected outside the tank 4.
[0028] Specifically, the biogas produced after the garbage enters the tank 4 is pumped into the biogas digester 7 through the ventilation pipe 5 by the exhaust fan 6.
[0029] An air pump 6 is fixedly connected to the outside of the ventilation pipe 5, and one end of the ventilation pipe 5 is fixedly connected to the outside of the biogas digester 7.
[0030] An incubator 15 is fixedly connected to the top of the tank 4, and a port 16 is fixedly connected to the top of the incubator 15.
[0031] A second motor 17 is fixedly connected to the top of the incubator 15. A second drive rod 18 is rotatably connected to the output end of the second motor 17. A second gear 20 is fixedly connected to the outside of the second drive rod 18.
[0032] Specifically, driven by the second motor 17, the second drive rod 18 drives the external second gear 20 to rotate, and the second gear 20 drives the external third gear 21 to rotate.
[0033] The second gear 20 is externally meshed with a third gear 21, and the third gear 21 is internally fixedly connected with a rotating rod 22. The second drive rod 18 is externally fixedly connected with multiple stirring rods 19.
[0034] Specifically, the third gear 21 drives the internal rotating rod 22 to rotate, which in turn drives the external stirring rod 19 to rotate together with the second drive rod 18.
[0035] A filter plate 23 is fixedly connected inside the incubator 15, a limiting plate 24 is slidably connected inside the incubator 15, and an electric push rod 25 is fixedly connected to the outside of the limiting plate 24.
[0036] Specifically, the wastewater in the garbage is separated by the filter plate 23, and then left to stand for a period of time to generate biochemical bacteria. Subsequently, the limit plate 24 is moved by the electric push rod 25 to allow the biochemical bacteria to enter the tank 4 through the hole.
[0037] Working principle: Waste is poured into the incubator 15 through port 16. Driven by the second motor 17 and the second drive rod 18, the external second gear 20 rotates. The second gear 20 drives the external third gear 21, which in turn drives the internal rotating rod 22. This, in turn, causes the rotating rod 22 and the second drive rod 18 to drive the external stirring rod 19, thus stirring the waste. The waste is then separated from the waste by the filter plate 23. After a period of settling, biochemical bacteria are generated. Subsequently, driven by the electric push rod 25, the limiting plate 24 moves, allowing the biochemical bacteria to enter the tank 4 through the holes. In this way, the self-made biochemical bacteria can be acclimatized to the environment, allowing the bacterial population to gradually adapt. Due to the harsh environment of leachate, compared with commercially available general-purpose bacteria, it has a stronger ability to degrade target pollutants. The biogas produced after the garbage enters the tank 4 is pumped into the biogas digester 7 through the ventilation pipe 5 by the air pump 6. Driven by the first motor 11, the first drive rod 10 drives the external first gear 9 to rotate. The first gear 9 moves under the action of the external rack 8, thereby driving the first drive rod 10 to move the external connecting rod 12. The connecting rod 12 moves the external top cover 13, sealing the biogas digester. This isolates the digester from outside air, especially oxygen, preventing oxygen from inhibiting the metabolic activity of anaerobic bacteria, ensuring the stable decomposition of organic matter, and thus increasing biogas production.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
