Description

Technical Field

[0001] This application relates to the field of landfill leachate treatment, specifically a leachate tower treatment device. Background Technology

[0002] Landfill leachate mainly refers to a high-concentration organic wastewater formed from the moisture contained in the landfill itself, rainwater and snowmelt entering the landfill, and other moisture, after deducting the saturated water holding capacity of the landfill and the cover soil layer, and passing through the landfill and cover soil layers. To facilitate timely and convenient treatment of landfill leachate, especially the treatment of heavy metal pollution contained in the leachate, some miniaturized leachate treatment devices have emerged. Patent document CN105540749A discloses a rural landfill leachate tower treatment device, which consists of a buffer tank, a water lifting device, a water distributor, a reaction tower, an electrochemical catalyst material, a vent, a water collection tank, a drain pipe, a support frame, and an intelligent control system. The water lifting device transports the wastewater from the buffer tank to the water distributor located at the top of the reaction tower. The water distributor distributes the wastewater to the top of the reaction tower, and the wastewater flows down the reaction tower, reacting completely with the electrochemical catalyst material, turning into clear water, and then entering the water collection tank at the bottom of the reaction tower, finally being discharged from the drain pipe. Simultaneously, air enters the reaction tower from the bottom up through the vent, providing oxygen for the reaction. This landfill leachate tower treatment device has a large capacity for treating wastewater, high volumetric load, small footprint, low operating cost, and wide applicability. However, because its buffer tank (leachate tank) is located directly below the support frame and its top is very close to the top of the support frame, it is inconvenient to send leachate into the buffer tank, and it is also inconvenient to observe and pre-treat the leachate in the buffer tank. Utility Model Content

[0003] The main objective of this application is to provide a leachate tower-type treatment device that allows the buffer tank to move freely in and out of the bottom of the support structure. To this end, this application adopts the following technical solution:

[0004] A leachate tower treatment device includes a reaction tower filled with electrochemical catalyst material, a water collection tank at the bottom of the reaction tower, a drain pipe connected to the water collection tank, a support frame at the bottom of the water collection tank, a buffer pool at the bottom of the support frame, and a water pump connected between the buffer pool and the reaction tower. The improvement lies in that: a guide rail is provided below the buffer pool, extending directly below the support frame; wheels are provided at the bottom of the buffer pool, allowing movement along the guide rail; a pipe is provided at the front end of the pipe at the water pump inlet, and a water outlet is provided on the side wall of the buffer pool, with the pipe inserted into the outlet.

[0005] The leachate tower treatment device provided in this application can achieve at least the following beneficial effects: By adding wheels to the buffer tank and installing guide rails below the buffer tank, the buffer tank can be moved; at the same time, a pipe is added to the front end of the water pump inlet pipe to connect to the side wall of the buffer tank in a plug-in manner to ensure that the leachate can be pumped. Thus, the leachate in the buffer tank can be easily observed and pretreated as needed, and the buffer tank can be cleaned and repaired. Attached Figure Description

[0013] like Figures 1-3As shown, the leachate tower treatment device of this embodiment includes a reaction tower 1 filled with electrochemical catalyst material, a water collection tank 2 located at the bottom of the reaction tower 1, a drain pipe 3 connected to the water collection tank 2, a support 4 supported at the bottom of the water collection tank 2, a buffer tank 5 located at the bottom of the support 4, and a water pump 11 connected between the buffer tank 5 and the reaction tower 1. The specific structure of the above components and the wastewater treatment method within the reaction tower 1 can be found in the references mentioned in the background section. The main difference between this embodiment and the prior art is that: a guide rail 6 is provided below the buffer tank 5, extending directly below the support 4; wheels 7 are provided at the bottom of the buffer tank 5, allowing the wheels 7 to move along the guide rail 6; an insertion pipe 8 is provided at the front end of the pipe at the inlet of the water pump 11, and a water outlet 9 is provided on the side wall of the buffer tank 5, with the insertion pipe 8 inserted into the water outlet 9.

[0014] The outlet 9 is located on the upper part of the side wall of the buffer tank 5. A water inlet pipe 10 is installed inside the buffer tank 5. One end of the water inlet pipe 10 is connected to the outlet 9, and the other end is located at the bottom of the buffer tank 5. A buffer sleeve 12 made of flexible material is fitted inside the outlet 9. The insertion tube 8 is a conical shape with a smaller front end and a larger rear end. The buffer sleeve 12 is made of rubber. The buffer sleeve 12 can be designed to be detachable for easy replacement. This structure of the buffer tank 5 prevents leachate wastewater from being discharged from the outlet 9 after the insertion tube 8 detaches; it also ensures that the insertion tube 8 is tightly inserted into the outlet 9, improving the watertightness of the connection point.

[0015] A base plate 13 is fixed to the bottom of the water pump 11. A support rod 14 is fixedly supported between the insertion pipe 8 and the base plate 13. Several slotted holes 15 are opened on both sides of the water pump 11 on the base plate 13. A support platform 16 is provided below the water pump 11. Bolts 17 connect the support platform 16 and the slotted holes 15. The slotted holes 15 and bolts 17 allow for fine adjustment of the position of the water pump 11 and the insertion pipe 8 to ensure that the insertion pipe 8 is aligned with the outlet 9.

[0016] A drive motor 18 is located next to the end of the guide rail 6. The output shaft of the drive motor 18 is connected to a lead screw drive device 19. The lead screw of the lead screw drive device 19 is parallel to the guide rail 6, and the nut of the lead screw drive device 19 is fixed to the bottom of the buffer pool 5. Lead screw drive is a conventional transmission method in this field. It can provide power for the movement of the buffer pool 5, saving manpower.

[0017] Brake switches 20 are provided at both ends of the guide rail 6, and the brake switches 20 are electrically connected to the drive motor 18. When the wheel 7 moves slowly and touches the brake switch 20, it can trigger the drive motor 18 to stop, thereby stopping the movement of the buffer tank 5. Of course, the components included in the leachate tower treatment device provided in this application are not limited to the components mentioned above. For example, it may also include a start switch to control the start of the drive motor 18, a pipeline connected to the drain pipe 3, etc.

[0018] It should be understood that all the above embodiments are exemplary and not restrictive. Various modifications or variations made by those skilled in the art to the specific embodiments described above under the concept of this application should be within the protection scope of this application.
