[0012] Preferably, gas extraction pipes are uniformly and fixedly connected to the upper end of the conveying and purification box.

[0013] A method for using a multi-dimensional environmentally friendly filtration device for landfill leachate includes the following steps:

[0014] S1. During use, the permeate can be transported to the interior of the transport purification box through the transport connection pipe. When the permeate enters the interior of the transport purification box through the transport connection pipe, the permeate will first be intercepted and filtered by the filter interception frame that slides into the transport purification box. This can filter and intercept impurities and debris inside the permeate, so that the permeate can be filtered for the first time.

[0015] S2. The filtered permeate continues to be conveyed along the conveying purification box. At this time, the various baffles are alternately inserted into the interior of the conveying purification box by the first electric push rod to intercept the permeate, allowing it to be conveyed along the conveying purification box to each purification treatment box. Then, the neutralization and purification solution in each storage dosing tank is driven by the third electric push rod to slide the dosing piston along the storage dosing tank, allowing the solution inside the storage dosing tank to be conveyed to the purification treatment box. Then, the second electric valve is closed to close the front end of the storage dosing tank. Then, the motor is started to drive a rotating adjustment gear plate to rotate. Through the set synchronous rotating wheel and synchronous transmission belt, each rotating adjustment gear plate can rotate synchronously. The rotating adjustment gear plate can make the stirring and mixing purification impeller rotate inside the purification treatment box, so that the permeate flowing into the purification treatment box is fully mixed and reacted with the neutralization and purification solution. This allows the permeate to be fully purified after passing through the three purification treatment boxes for neutralization and reaction.

[0016] S3. After purification, open the first electric valve to allow the purified permeate to be discharged and transported through the discharge pipe.

[0017] The beneficial effects of this invention are:

[0018] 1. During the use of this invention, the permeate can be transported to the interior of the transport purification box through the transport connection pipe. When the permeate enters the interior of the transport purification box through the transport connection pipe, the permeate will first be intercepted and filtered by the filter interception frame that slides into the transport purification box. This can filter and intercept impurities and debris inside the permeate, allowing the permeate to undergo the first filtration treatment. The second electric push rod can control the lifting of the sealing protective cover, which allows the third electric push rod to lift the filter interception frame and clean away the intercepted impurities inside, making filtration and cleaning convenient and quick.

[0019] II. This invention uses a first electric push rod to alternately insert into the interior of the conveying purification tank for interception, allowing the permeate to be conveyed along the conveying purification tank to each purification treatment tank. At this time, the neutralizing and purifying solution in each storage dosing tank is driven by a third electric push rod to slide along the storage dosing tank, allowing the solution inside the storage dosing tank to be conveyed to the purification treatment tank. Then, the second electric valve closes to shut off the front end of the storage dosing tank. Then, the motor is started to drive a rotating adjusting gear plate to rotate. Through the set synchronous rotating wheel and synchronous transmission belt, each rotating adjusting gear plate can rotate synchronously. The rotating adjusting gear plate can cause the stirring and mixing purification impeller to rotate inside the purification treatment tank, so that the permeate flowing into the purification treatment tank is fully mixed and reacted with the neutralizing and purifying solution. This allows the permeate to be fully purified after passing through the three purification treatment tanks for neutralization and reaction. Attached Figure Description

The purification treatment box 23 is evenly arranged, and the stirring and mixing purification impeller 21 is symmetrically and rotatably installed inside the purification treatment box 23. The rotating adjusting gear disc 22 is rotatably engaged with the side end of the purification treatment box 23 and is fixedly connected to the middle of the end of the stirring and mixing purification impeller 21. The synchronous rotating wheel 20 is fixedly connected to the middle of the rotating adjusting gear disc 22.

A motor 18 is arranged on the outer side of the synchronous rotating wheel 20 in the middle, and the drive end of the motor 18 is fixedly connected to the middle of the rotating adjusting gear 22. The motor 18 is fixedly connected to the fixed mounting plate 19. When the motor 18 is started, it drives one rotating adjusting gear 22 to rotate. Through the synchronous rotating wheel 20 and the synchronous transmission belt 17, each rotating adjusting gear 22 can rotate synchronously. The rotating rotating adjusting gear 22 can make the stirring and mixing purification impeller 21 rotate inside the purification treatment box 23, so that the permeate flowing into the purification treatment box 23 can be fully mixed and reacted with the neutralized and purified medicine.

[0045] S1. During use, the permeate can be transported to the interior of the transport purification box 3 through the transport connection pipe 7. When the permeate enters the interior of the transport purification box 3 through the transport connection pipe 7, the permeate will first be intercepted and filtered by the filter interception frame 15 that is slidably inserted into the transport purification box 3. This can filter and intercept impurities and debris inside the permeate, so that the permeate can be filtered for the first time.

[0046] S2. The filtered permeate continues to be conveyed along the conveying purification tank 3. At this time, the various baffle plates 4 are alternately inserted into the interior of the conveying purification tank 3 by the first electric push rod 9 to intercept the permeate, allowing it to be conveyed along the conveying purification tank 3 to each purification treatment tank 23. Then, the neutralization and purification solution in each storage dosing tank 26 is driven by the third electric push rod 29 to slide the dosing piston 27 along the storage dosing tank 26, so that the solution inside the storage dosing tank 26 is conveyed to the purification treatment tank 23. Then, the second electric valve 24 is closed to allow the permeate to be conveyed to the purification treatment tank 23. The front end of the storage tank 26 is closed, and then the motor 18 is started to drive a rotating adjustment disc 22 to rotate.
