Problems solved by technology

However, most of the landfill sites are remote, and the construction area of ​​the new screening project is limited by external factors such as topography and surrounding railways.
Backfilling the fine soil and rejects to the landfill in the traditional sieving project not only has safety hazards but also wastes resources, and due to the...

Embodiment Construction

[0015] Combine below Figure 1 to Figure 2 The present invention is further described.

[0016] The present invention relates to an in-situ sorting method for stock garbage in a landfill. The process is as follows: stabilizing the garbage pile, excavating and transporting the garbage, crushing bulky garbage, vibrating to disperse the garbage, and using a first-stage drum sieve 11 and a disc Type separator 12 sieves fine soil garbage, utilizes wind force separator 13 to sieve aggregate garbage, utilizes secondary drum sieve 14 to sieve reject object garbage, packs combustibles.

[0017] Stabilization treatment is the process of rapidly stabilizing the garbage dump through technical measures such as air injection ventilation and air extraction. Drive the air injection pipe and air extraction pipe into the garbage dump. The penetration depth should be 0.5-1m greater than the mining depth. The air injection pipe and the air extraction pipe are connected to the fan through flexibl...

Abstract

The invention discloses an in-situ screening method for landfill stock garbage. The method comprises the following specific steps of stably treating garbage heaps, excavating and transporting garbage,crushing large garbage, vibrating and scattering the garbage, screening fine soil garbage by using a primary drum screen and a disc separator, screening aggregate garbage by using a wind separator, screening rejected garbage by using a secondary drum screen, and packing combustible materials. Stock garbage is screened into four substances including fine soil, aggregate, rejected materials and combustible materials, the four substances are recycled and treated separately, the garbage is prevented from being accumulated in a landfill, and the harmless, recycling and reduction renovation purposeis achieved. The method can be widely applied to the technical field of garbage treatment.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to an in-situ sorting method for existing garbage in a landfill. Background technique [0002] Due to the short period of time for the harmless treatment of domestic waste to be generally implemented in my country, there are stockpiles of informal domestic waste dumps, non-standard domestic waste treatment facilities, and landfills with saturated storage capacity due to historical reasons and insufficient waste disposal facilities. There are relatively many waste treatment projects, so the stock treatment market in my country is huge at present. At present, most landfills that are preparing to carry out sieving work are facing the dilemma that the landfill is close to full capacity and the domestic waste has nowhere to go. Therefore, the efficiency of the sieving project is high. However, most landfills are located in remote locations, and the construction area of ​​new sc...
