The current regulator adjusts the output micro-current, which is then applied to the leachate through the cathode and anode plates. Meanwhile, the air pump draws in external air and injects it into the aeration pipe through the connection between the air inlet and the aeration head. This external air is then transported into the leachate to provide oxygen for the microorganisms and to ensure uniform mixing of the landfill leachate. Thus, the synergistic effect of the micro-current and aeration effectively enhances the biochemical activity of microorganisms in the landfill leachate.

[0023] 2.

At the same time as the aeration pipe rotates, the vertical rod installed at the top and the stirring blades simultaneously stir the leachate. This allows for a more uniform distribution of dissolved oxygen, nutrients, and microorganisms in the landfill leachate. During aeration, stirring can accelerate the mass transfer rate of oxygen from the gas phase to the liquid phase, allowing microorganisms to have more full contact with oxygen and nutrients, thus improving the metabolic activity of microorganisms and treatment efficiency.

[0033] Please see Figures 1-6 This utility model provides a technical solution: a microcurrent high biochemical activity activation device for landfill leachate, comprising:

[0034] The processing cylinder 1 includes a cylinder body 11, and a cylinder cover 12 is installed on the top of the cylinder body 11. A liquid inlet pipe 13 for liquid inlet is connected to one side of the top of the cylinder cover 12.

[0035] The activity enhancement mechanism 2 is installed through the inner and outer sides of the cylinder 11 to activate the biochemical activity of microorganisms in the filtrate, and includes a mounting frame 21 fixedly installed inside the cylinder 11, with a cathode plate 22 installed through one side inside the mounting frame 21 and an anode plate 23 installed through the other side inside the mounting frame 21.

[0036] Treatment components 24 are installed through both the inner and outer sides of the treatment cylinder 1 to activate the biochemical activity of microorganisms in the filtrate.

[0037] Reference Figure 2 , Figure 3 as well as Figure 4As shown, the processing assembly 24 includes a controller 241 mounted on the surface of the cylinder 11, and a battery 242 mounted on the top of one side of the cylinder 11. A current regulator 243 is mounted on one side of the cylinder 11 and at the bottom of the battery 242. The electrical output terminal of the current regulator 243 is connected to the electrical input terminals of the cathode plate 22 and the anode plate 23, respectively. The electrical output terminal of the battery 242 is connected to the electrical input terminal of the current regulator 243.

[0038] An aeration pipe 244 is provided at the bottom of the inner cavity of the cylinder 11, and several aeration heads 245 are connected to the top of the aeration pipe 244. A protective shell 246 is fixedly installed at the bottom of the inner cavity of the cylinder 11, and an air inlet shell 247 is fixedly installed at the bottom of the inner cavity of the protective shell 246. A vertical pipe 248 is connected to the bottom of the aeration pipe 244, and the bottom end of the vertical pipe 248 passes through the protective shell 246 and the air inlet shell 247 in sequence and extends into the interior of the air inlet shell 247. A connecting pipe 249 is connected to one side of the air inlet shell 247, and one end of the connecting pipe 249 passes through the protective shell 246 and the cylinder 11 in sequence and extends into the exterior of the cylinder 11. An air pump 2401 is connected to the bottom of one side of the cylinder 11, and the end of the connecting pipe 249 located outside the cylinder 11 is connected to the air outlet of the air pump 2401.

[0039] In this embodiment, leachate is introduced into the interior of the cylinder 11 through the inlet pipe 13. Simultaneously, the controller 241 activates the current regulator 243 to work synchronously with the air pump 2401. The current regulator 243 adjusts the output micro-current, which is then applied to the leachate through the cathode plate 22 and the anode plate 23. Meanwhile, the air pump 2401 draws in external air and injects it into the aeration pipe 244 through the connection pipe 249 and the air inlet shell 247. The air is then transported into the leachate through the aeration head 245, providing oxygen for the microorganisms and ensuring uniform mixing of the leachate. This synergistic effect of micro-current and aeration effectively enhances the biochemical activity of microorganisms in the leachate.

[0040] Reference Figure 4 , Figure 5 and Figure 6As shown, a crossbar 2402 is installed through one side of the protective shell 246, and a worm gear 2403 is installed on the surface of the crossbar 2402 inside the protective shell 246. A worm wheel 2404 is installed on the surface of the vertical pipe 248 inside the protective shell 246, and the worm wheel 2404 and the worm gear 2403 are meshed together. One end of the crossbar 2402 outside the protective shell 246 passes through the cylinder 11 and extends to the outside of the cylinder 11. A driven bevel gear 2405 is fixedly installed on the end of the crossbar 2402 outside the cylinder 11. A motor 2406 is installed at the bottom of the other side of the cylinder 11.

A vertical rod 2408 is fixedly installed on the top of the aeration pipe 244, and an stirring blade 2409 is installed on the surface of the vertical rod 2408 between the cathode plate 22 and the anode plate 23.

[0041] In this embodiment, the controller 241 turns on the motor 2406 to operate, and uses the meshing connection between the driving bevel gear 2407 and the driven bevel gear 2405 to drive the crossbar 2402 and the worm gear 2403 to rotate synchronously. Then, the meshing connection between the worm gear 2403 and the worm wheel 2404 drives the vertical pipe 248 and the aeration pipe 244 to rotate, thereby increasing the gas-liquid contact area. While the aeration pipe 244 rotates, the vertical rod 2408 installed at its top and the stirring blade 2409 simultaneously stir the leachate. This allows the dissolved oxygen, nutrients and microorganisms in the landfill leachate to be more evenly distributed. During the aeration process, stirring can accelerate the mass transfer rate of oxygen from the gas phase to the liquid phase, allowing microorganisms to have more full contact with oxygen and nutrients, thereby improving the metabolic activity of microorganisms and the treatment efficiency.

Among them, the protective housing 26 located on the surface of the air pump 2401 has an air inlet on one side, and a dustproof plate is fixedly installed inside the air inlet.

[0043] In this embodiment, protection can be provided for the air pump 2401, motor 2406, battery 242 and current regulator 243.

[0044] Reference Figure 6 As shown, bolts 25 are installed through both sides of the top of the cathode plate 22 and the anode plate 23, and the cathode plate 22, the anode plate 23 and the mounting bracket 21 are fixedly connected by bolts 25.

[0045] In this embodiment, it is easy to disassemble and maintain the cathode plate 22 and the anode plate 23 to avoid damage to the cathode plate 22 and the anode plate 23 after long-term use.

[0046] Reference Figure 1 as well as Figure 2 As shown, a drain pipe 14 is connected to the bottom of the front side of the cylinder 11, and a valve 15 is connected to one end of the drain pipe 14 via a flange.

[0047] In this embodiment, after the leachate treatment is completed, valve 15 can be opened to discharge the treated leachate inside the cylinder 11 through drain pipe 14.

[0048] Working principle: When treating landfill leachate, the leachate is introduced into the interior of the cylinder 11 through the inlet pipe 13. At the same time, the controller 241 turns on the current regulator 243 to work synchronously with the air pump 2401. The current regulator 243 adjusts the output micro current so that the micro current is applied to the leachate through the cathode plate 22 and the anode plate 23. Meanwhile, the air pump 2401 draws in external air and injects it into the interior of the aeration pipe 244 through the connection pipe 249 and the air inlet shell 247. The external air is then transported into the leachate through the aeration head 245 to provide oxygen for the microorganisms and to make the landfill leachate uniformly mixed.

[0049] Furthermore, while improving the biochemical activity of landfill leachate, the controller 241 turns on the motor 2406 to work, and uses the meshing connection of the driving bevel gear 2407 and the driven bevel gear 2405 to drive the crossbar 2402 and the worm gear 2403 to rotate synchronously. Then, the meshing connection of the worm gear 2403 and the worm wheel 2404 drives the vertical pipe 248 and the aeration pipe 244 to rotate, so as to increase the gas-liquid contact area. While the aeration pipe 244 rotates, the vertical rod 2408 installed on its top and the stirring blade 2409 simultaneously stir the leachate.
