Embodiment

[0052] figure 1 It shows a schematic diagram of deconstruction of the concentrated liquid reinjection well used for the landfill closure project according to this embodiment; figure 2 show figure 1 Sectional view of A-A; image 3 show figure 1 Sectional view of B-B.

[0053] Such as Figure 1 to Figure 3 , the concentrated liquid reinjection well used for the landfill closure project, including:

[0054] The horizontal recharge blind ditch is set inside the garbage dump body 8 and connected to the concentrated liquid delivery pipe 10. The inspection well 6 extends from the covering layer 9 on the top of the garbage dump body 8 to the horizontal refill blind ditch. The extension direction of the horizontal recharge blind ditch is arranged at intervals. The distance between the top of the horizontal recharge blind ditch and the bottom of the covering layer 9 is 1000 mm, the distance between the bottom of the vertical recharge blind ditch and the bottom of the horizontal r...

Abstract

The invention discloses a concentrated solution recharge well for a refuse landfill closure project. The concentrated solution recharge well comprises an inspection well, a transverse recharge blind ditch and a plurality of vertical recharge blind ditches which communicate with one another; the transverse recharge blind ditch is arranged in a garbage heap body and is connected to a concentrated solution conveying pipe; the inspection well extends to the transverse recharge blind ditch from a covering layer at the top of the garbage heap body; the plurality of vertical recharge blind ditches are arranged at intervals in the extending direction of the transverse recharge blind ditch. A full-underground recharge structure is adopted, the recharge efficiency of the concentrated solution is effectively improved, the influence of the concentrated solution on the environment in the recharge process is reduced, meanwhile, the recharge condition of the concentrated solution can be mastered at any time by arranging the inspection well, and the recharge speed and time of the concentrated solution can be reasonably controlled.

Description

technical field [0001] The invention belongs to the field of waste landfill closure technology, and more particularly relates to a concentrated liquid reinjection well used for a waste landfill closure project. Background technique [0002] When the landfill site is operated to the design elevation or the garbage dump site no longer accepts garbage and ceases to be used, it needs to be closed. The landfill closure project includes surface water runoff control, drainage, anti-seepage, leachate collection and treatment, landfill gas collection and treatment, pile stabilization, vegetation type selection and coverage, etc. After domestic waste enters the landfill, a large amount of leachate will be produced through anaerobic fermentation. After the leachate is collected and treated, the water that meets the standard will be discharged directly to the outside. However, due to technological reasons, the remaining part of the concentrated liquid needs to be recharged. Pour into t...
