Treating system for land reclamation of refuse landfill site and treating method

Abstract

The invention discloses a treating system for land reclamation of a refuse landfill site and a treating method, wherein the treating method comprises the following steps: the whole landfill site is dug again, and all substances outside large objects are crushed; all the substances enter a first-group roller sieving machine for separation; the substances on the sieve are packaged by combustible materials sorted by a winnowing machine; bricks / tiles / stones are filled on site; the substances under the sieve enter a second-group roller sieving machine for separation; the substances under the sieve are magnetically separated and are prepared into humus soil for soil improvement; the substances on the sieve are transferred to the second-group windowing machine for separation; and harmless land is obtained. The treating system and the treating method disclosed by the invention have the beneficial effects that the devices are matched to remove large refuse materials, and refuse clearing is quickly finished in limited time by sectioned treatment of multi-stage sieving, so that the purpose of harmless reclamation is realized for the land in short period; a large amount of cleared and processed humus soil can be used for planting forest trees to absorb carbon dioxide and release oxygen, so that the conditions of atmospheric pollution and haze can be improved; and especially, the land resource can be reutilized, so that the treating system and the treating method has immeasurable strategic significance for guaranteeing the warning limit of arable land of China.

Description

technical field [0001] The invention relates to a treatment system and method for a garbage landfill, in particular to a treatment system and method for land reuse of a domestic garbage landfill. Background technique [0002] At present, the waste disposal methods widely used in China mainly include sanitary landfill, incineration, and composting. Since the late 1980s, my country began to establish standardized landfills. These landfills have been greatly improved compared with the original dumps (informal landfills). Corresponding control measures have been taken for the pollution of landfill gas and landfill gas; in terms of construction management, landfill in different areas, layered compaction, and regular soil covering have been implemented. Due to its large processing capacity, strong adaptability, one-time treatment, no residue, convenient management and reasonable operating costs, the sanitary landfill method has become the main means of urban solid waste treatment ...

AI Technical Summary

Problems solved by technology

[0010] However, there are two problems that cannot be ignored in the above-mentioned attempt: 1) so far, this processing mode is limited to small-scale, small-scale daily processing tonnage

This kind of long-term operation cannot solve the purpose of landfill reuse; 2) Due to the rapid development of urbanization, the urban construction and population of cities (especially first-tier cities) are rapidly expanding, and the existing landfill, or The closed landfills are all located in densely populated areas. If a landfill is reused in an area for up to 15 years, it will cause serious problems due to the long-term impact on the surrounding environment and long-term disturbance of residents due to the long-term operation process.
