[0019] The first embodiment of this application is:

[0020] See also Figure 1-Figure 3 ,in Figure 1 It is a schematic diagram of the overall structure of the first embodiment of the utility model; Figure 2 This is a schematic structural diagram of the observation assembly of the first embodiment of the present utility model; Figure 3 It is a structural schematic diagram of the guide assembly of the first embodiment of the present utility model.

[0021] The utility model provides a landfill leachate treatment device, which includes a waterproof landfill pool 101, two filter racks 102, an integrated treatment box 103 and a selection mechanism. The selection mechanism includes a partition 104, two leachate buckets 105, two observation components and two diversion components. The observation component includes an observation tube 106, a sealing cover 107 and a scale 108. The diversion component includes a mounting frame 109, an infusion tube 110, a liquid pump 111, an infusion port 112, an infusion valve 113 and a flange 114. The above-mentioned solution solves the problem that the above existing technology cannot landfill and treat leachate of different types of garbage, and a new landfill needs to be built to treat hazardous waste and the leachate generated, which has a high treatment cost.

[0022] According to this specific embodiment, the waterproof landfill pool 101 is provided with two filter ports, the two filter mesh frames 102 are respectively fixedly connected to the two filter ports, and are each provided with a plurality of filter mesh plates, filtrate permeation membranes and filter membranes. The integrated treatment box 103 is arranged on one side of the waterproof landfill pool 101, the partition 104 is fixedly connected to the waterproof landfill pool 101 and is located between the two filter ports, the two leachate buckets 105 are fixedly connected to the waterproof landfill pool 101 and are respectively located below the two filter ports, the two observation components are respectively arranged on one side of the two leachate buckets 105, and the two diversion components are respectively located between the two leachate buckets 105 and the integrated treatment box 103. When the garbage is processed , pour domestic garbage and other garbage into the two sides of the partition 104 in the waterproof landfill pool 101 respectively, fill them with soil respectively, and cover them with geotextile to prevent excessive rainwater from increasing the leachate. The two observation components respectively observe the liquid level of the leachate in the two leachate buckets 105. As needed, start one of the diversion components to draw the leachate in one leachate bucket 105 into the integrated treatment box 103 for treatment until the extracted leachate is completely treated and discharged from the integrated treatment box 103. Start another diversion component to treat the leachate in the other leachate bucket 105, and stagger the treatment to prevent harmful leachate produced by other garbage from mixing with the leachate produced by domestic garbage, causing unknown reactions.

[0023] Among them, the observation tube 106 is fixedly connected to the waterproof landfill pool 101 and one side of the leachate hopper 105, and is communicated with the interior of the leachate hopper 105. The sealing cover 107 is hinged on the top of the observation tube 106, and the scale 108 is fixedly connected to the inside of the observation tube 106. When observing the liquid level of the leachate in the leachate hopper 105, the sealing cover 107 is opened and the size of the scale 108 submerged in water is observed to judge the liquid level of the leachate, so as to decide whether to treat the leachate.

[0024] Secondly, the mounting bracket 109 is fixedly connected to one side of the integrated processing box 103, the infusion tube 110 is slidingly connected to the mounting bracket 109 and fixedly connected to one side of the leachate bucket 105, and the liquid pump 111 is fixedly connected to the leachate bucket 105 and communicated with the interior of the infusion tube 110. When extracting the leachate, the infusion tube 110 is placed in the mounting bracket 109, which can reduce the tension at the connection of the infusion tube 110 and make the connection more stable. The liquid pump 111 is used to draw the leachate in the leachate bucket 105 into the integrated processing box 103 along the infusion tube 110.

The infusion valve 113 is arranged on the infusion port 112, and the flange 114 is arranged at the connection between the infusion port 112 and the infusion tube 110. When the leachate needs to be input into the integrated processing box 103, the infusion valve 113 is opened and the liquid pump 111 is started. The leachate enters the integrated processing box 103 along the infusion tube 110 and the infusion port 112 for treatment.

[0026] When treating garbage, domestic garbage and other garbage are poured into the two sides of the partition 104 in the waterproof landfill pool 101 respectively, and are filled with soil and covered with geotextiles to prevent excessive rainwater from increasing the amount of leachate. The garbage leachate is filtered with the help of the components on the two filter racks 102 and flows into the two leachate buckets 105 respectively. The sealing cover 107 is opened and the size of the scale 108 submerged in water is observed to determine the liquid level of the leachate, so as to decide whether to treat the leachate. As needed, the corresponding liquid pump 111 is started to pump the leachate in the leachate bucket 105 along the liquid infusion pipe 110. The leachate is drawn into the integrated treatment box 103 for treatment until the extracted leachate is completely treated and discharged from the integrated treatment box 103, and another diversion component is started to treat the leachate in the other leachate bucket 105. Peak-shifting treatment is carried out to prevent harmful leachate produced by other garbage from mixing with leachate produced by domestic garbage, causing unknown reactions. This avoids the problem that the existing technology cannot landfill and treat leachate of different types of garbage, and a new landfill needs to be built to treat hazardous waste and the leachate produced by it, which results in high treatment costs. The effect of using one device to treat leachate produced by domestic garbage and other garbage is achieved, thereby reducing treatment costs.

[0027] The second embodiment of this application is:

[0028] See also Figure 4 , Figure 4 It is a schematic diagram of the overall structure of the second embodiment of the present utility model.

[0029] On the basis of the first embodiment, the landfill leachate treatment device of this embodiment further includes an auxiliary mechanism, which includes an observation window 201 and an isolation box 202 .

[0030] Among them, the observation window 201 is embedded above the integrated treatment box 103, and the isolation box 202 is fixedly connected to the top of the waterproof landfill pool 101. When treating two types of leachates respectively, the situation in the integrated treatment box 103 can be observed through the observation window 201 so as to treat the other leachate; when landfilling other garbage, the other garbage is piled up in the isolation box 202, and soil landfill and geomembrane covering are carried out, and the edge of the isolation box 202 is always higher than the soil. If the leachate generated by other garbage is toxic, the isolation box 202 can effectively isolate the toxic substances and prevent other soils from being contaminated, thereby achieving the effect of improving the functionality of the device.
