Description

Technical Field

[0001] This utility model relates to the field of landfill leachate treatment technology, specifically a novel device for treating new pollutants in landfill leachate. Background Technology

[0002] Landfill leachate, also known as leachate, leachate solution, or leaching liquid, refers to secondary pollutants generated during the storage and disposal of waste due to rainwater rinsing and scouring, as well as soaking by surface water and groundwater. These pollutants are produced through extraction, hydrolysis, and fermentation. The main sources are the water contained within the waste itself, water produced by the biochemical reactions of waste, and atmospheric precipitation. It mainly includes landfill leachate, waste incineration plant leachate, integrated waste treatment plant leachate, and waste transfer station leachate.

[0003] Landfill leachate is characterized by high pollutant concentrations and significant ecological risks. In particular, leachate from older landfills can contain levels of conventional pollutants such as biochemical oxygen demand (BOD) and chemical oxygen demand (COD) that are up to 10 times higher than those found in urban sewage. Furthermore, it contains various persistent new pollutants, including heavy metals, endocrine disruptors, pesticides, plasticizers, chlorinated and halogenated organic compounds. These persistent new pollutants have carcinogenic, teratogenic, and mutagenic effects, posing serious threats to microorganisms, wildlife, and humans.

[0004] Because biological treatment processes are inexpensive and can degrade COD and BOD in landfill leachate to some extent, while also removing nitrogen and phosphorus, they remain the dominant technology in wastewater treatment equipment. Examples include membrane bioreactors (MBR), upflow anaerobic sludge blanket (UASB), and sequential batch activated sludge processes (SBR). However, the effluent from these technologies still struggles to meet relevant national emission standards, and their insufficient oxidation capacity makes them ineffective at degrading new pollutants.

[0005] The present invention aims to solve the technical problems existing in the prior art. To this end, a new type of treatment device for landfill leachate pollutants is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a novel device for treating new pollutants in landfill leachate, in order to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A novel treatment device for new pollutants in landfill leachate includes a degradation tank, an oxygenator fixedly connected to one side of the degradation tank, a hose fixedly connected to one end of the oxygenator, and a stirring device fixedly connected to the other end of the hose.

[0009] A drive mechanism is fixedly connected to one side of the degradation tank. The drive mechanism meshes with the stirring device. A communication device is fixedly connected to the degradation tank. The communication device cooperates with the stirring device.

[0010] As a further embodiment of this utility model: the connecting device includes a connecting pipe, which is located in the degradation tank and fixedly connected to the degradation tank. A connecting hole is opened on the cylindrical surface of the connecting pipe, and an extrusion block is fixedly connected to one side of the connecting pipe. The extrusion block cooperates with the stirring device.

[0011] As a further embodiment of this utility model: the stirring device includes a rotating cylinder, which is sleeved on the cylindrical surface of the connecting pipe and slides in contact with the connecting pipe. A guide groove is provided on the inner surface of the rotating cylinder, and the extrusion block is located in the guide groove and slides in contact with the guide groove. Several stirring rods are fixedly connected to the cylindrical surface of the rotating cylinder, and a lifting block is fixedly connected to the cylindrical surface of the rotating cylinder. The lifting block meshes with the driving mechanism.

[0012] As a further embodiment of this utility model: the driving mechanism includes a driving motor and a transmission shaft. The driving motor is fixedly connected to the degradation tank. One end of the driving motor is fixedly connected to the driving shaft, which extends into the degradation tank. A first gear is fixedly connected to the cylindrical surface of the driving shaft, and a belt is connected to the cylindrical surface of the driving shaft.

[0013] As a further embodiment of this utility model: the transmission shaft is located in the degradation tank and is rotatably connected to the degradation tank, the transmission shaft is connected to the drive shaft, and a second gear is fixedly connected to the cylindrical surface of the transmission shaft.

[0014] As a further embodiment of this utility model: both the second gear and the first gear are semi-circular in shape, the second gear and the first gear are in the same direction, the lifting block is cylindrical in shape, and the cylindrical surface of the lifting block is horizontally provided with several meshing grooves, which mesh with the second gear and the first gear.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: When the device is in use, the oxygen supply unit delivers oxygen to the rotating drum through a hose. The oxygen then enters the leachate through a connecting pipe and a connecting hole. Then, the drive motor starts, and the drive motor controls the drive shaft to rotate. The drive shaft drives the first gear to rotate, and at the same time, the drive shaft drives the transmission shaft to rotate through a belt. The transmission shaft drives the second gear to rotate. Since the first gear and the second gear are engaged with the lifting block, when the first gear rotates from 0 to 180 degrees, the first gear drives the lifting block to rise. When the first gear rotates from 180 to 360 degrees, the first gear disengages from the lifting block, and the second gear engages with the lifting block to drive the lifting block to descend. This forms a vertical reciprocating motion of the lifting block, which drives the rotating drum to move. The rotating drum drives the guide groove to move. Since the squeezing block is located in the guide groove and slides in contact with the rotating drum, and the guide groove is inclined, the rotating drum rotates due to the squeezing of the squeezing block during the descent of the guide groove. The rotating drum then drives the stirring rod to rotate and stir, improving the mixing efficiency of oxygen and leachate and enhancing the degradation effect of pollutants in the leachate.

A communication device is fixedly connected to the degradation tank 1. The communication device cooperates with the stirring device. This device can improve the mixing efficiency of oxygen and leachate and enhance the degradation effect of pollutants in leachate.

[0025] Please see Figure 1 and Figure 3 The connecting device includes a connecting pipe 5, which is located in the degradation tank 1 and fixedly connected to the degradation tank 1. A connecting hole 16 is opened on the cylindrical surface of the connecting pipe 5. An extrusion block 4 is fixedly connected to one side of the connecting pipe 5, and the extrusion block 4 cooperates with the stirring device.

[0026] Please see Figure 1 , Figure 2 and Figure 4 The stirring device includes a rotating drum 2, which is sleeved on the cylindrical surface of the connecting pipe 5 and slides in contact with the connecting pipe 5. A guide groove 6 is provided on the inner surface of the rotating drum 2, and the extrusion block 4 is located in the guide groove 6 and slides in contact with the guide groove 6. Several stirring rods 3 are fixedly connected to the cylindrical surface of the rotating drum 2, and a lifting block 13 is fixedly connected to the cylindrical surface of the rotating drum 2. The lifting block 13 is engaged with the driving mechanism.

[0027] Please see Figure 1-2 The driving mechanism includes a drive motor 14 and a transmission shaft 11. The drive motor 14 is fixedly connected to the degradation tank 1. One end of the drive motor 14 is fixedly connected to a drive shaft 7. The drive shaft 7 extends into the degradation tank 1. A first gear 8 is fixedly connected to the cylindrical surface of the drive shaft 7. A belt 15 is connected to the cylindrical surface of the drive shaft 7.

[0028] Please see Figure 2 The drive shaft 11 is located in the degradation tank 1 and is rotatably connected to the degradation tank 1. The drive shaft 11 is connected to the drive shaft 7, and a second gear 12 is fixedly connected to the cylindrical surface of the drive shaft 11.

[0029] Please see Figure 1-2 The second gear 12 and the first gear 8 are both semi-circular in shape, and the second gear 12 and the first gear 8 are in the same direction. The lifting block 13 is cylindrical in shape, and the cylindrical surface of the lifting block 13 is horizontally provided with several meshing grooves, which mesh with the second gear 12 and the first gear 8.

[0030] The working principle of this utility model is as follows: When the device is in use, the oxygen supply unit 9 delivers oxygen to the rotating drum 2 through the hose 10. The oxygen then enters the leachate through the connecting pipe 5 and the connecting hole 16. Then, the drive motor 14 starts, and the drive motor 14 controls the drive shaft 7 to rotate. The drive shaft 7 drives the first gear 8 to rotate. At the same time, the drive shaft 7 drives the transmission shaft 11 to rotate through the belt 15. The transmission shaft 11 drives the second gear 12 to rotate. Since the first gear 8 and the second gear 12 are engaged with the lifting block 13, when the first gear 8 rotates from 0 to 180 degrees, the first gear 8 drives the lifting block 13 to rise. When the rotation is 180 degrees and then 360 degrees, the first gear 8 disengages from the lifting block 13, and the second gear 12 engages with the lifting block 13, causing the lifting block 13 to descend. This forms a vertical reciprocating motion of the lifting block 13. The lifting block 13 drives the rotating drum 2 to move, and the rotating drum 2 drives the guide groove 6 to move. Since the squeezing block 4 is located in the guide groove 6 and slides in contact with the rotating drum 2, and the guide groove 6 is inclined, the rotating drum 2 rotates due to the squeezing of the squeezing block 4 during the descent of the guide groove 6. The rotating drum 2 then drives the stirring rod 3 to rotate and stir, thereby improving the mixing efficiency of oxygen and leachate and enhancing the degradation effect of pollutants in the leachate.
