Embodiment 1

[0027] Embodiment 1: a kind of processing technology of municipal refuse, comprises the following steps successively

[0028] 1. Garbage sorting: Screen and separate the recyclable parts (plastic, glass, metal, etc.), reusable parts (concrete blocks, clay and other inorganic substances) and organic waste in the municipal waste, and the organic waste is used for standby.

[0029] 2. Backfilling of the organic part:

[0030] ① Backfill the organic waste into the lower part of the landfill pit. The landfill pit is an anti-leakage structure formed by adding an anti-leakage film, and the backfill depth of the organic waste is 3 meters. Can include several for recycling.

[0031] ② Compaction: compact the organic waste;

[0032] ③Covering of agricultural and forestry organic waste: covering the organic waste with agricultural and garden organic waste, including plant stems, branches and leaves, straw, roots, etc., with a layer thickness of 30 cm;

[0033] ④Recharge: Evenly spray ...

Embodiment 2

[0038] Embodiment 2: a kind of processing technology of municipal refuse, comprises the following steps successively

[0039] One, garbage sorting: with embodiment 1;

Abstract

The invention relates to the technology field of garbage disposal, in particular to the processing technology of municipal garbage. The prior art of garbage landfill has problems in high cost, unfavorable disposal effect and a second pollution. The invention provides the processing technology for the municipal garbage, which is characterized in that the processing technology has the following procedures: 1, garbage separation: the recoverable and returnable municipal garbage and organic garbage are screened and separated and the organic garbage is for store; 2, the backfill of the organic garbage: (1) the organic garbage is backfilled into the landfill pit with leakage-preventing structure; (2) densification; (3) the agricultural organic waste is covered; (4) recharging; (5) unpolluted land is covered; and 3, recycling: (1) landfill gas is withdrawn; (2) percolate is reused. The invention has the advantages of low cost, good disposal effect, good and economic utility and the waste of land resource is avoided.

Description

Technical field: [0001] The invention relates to the technical field of garbage treatment techniques, in particular to a treatment technique for municipal garbage. Background technique: [0002] With the rapid development of economy and society and the acceleration of urbanization, the amount of municipal waste generated in China is constantly increasing. In order to solve this social problem, the existing technologies mainly use the following methods to deal with domestic waste, but there are deficiencies: 1. Sanitary landfill technology for municipal waste: single-cavity landfill is usually used for landfill, and the service life is usually 20-25 years. Production and discharge. This cycle can generally be 20-30 years or longer, depending on the local climate - mainly determined by temperature and rainfall. Therefore, in this cycle, there is always the risk of fire and explosion. In addition, due to organic The ground subsidence caused by the biodegradation of the garbage...
