Problems solved by technology

[0003] Due to the lack of scientific and practical sanitary landfill technology in the rainy season, domestic landfills are divided randomly. Especially in the rainy season, the roads in the landfill area are soft, vehicles are difficult to drive, and they are easy to break down; it is difficult to unload garbage; leachate and Rainwater cannot be diverted, resulting in a large amount of leachate and high operating costs; the leachate stagnant on the surface of the landfill area will also produce foul odors and breeding of mosquitoes and flies, causing environmental hygiene problems; a large number of permanent covering materials, such as loess, etc., reduce Landfill storage capacity

Embodiment Construction

[0011] In summer, waste is flattened and compacted in sanitary landfills mainly by BMW compactors, and the average density of the surface layer above 50cm reaches 0.9-1.1T / M 3 In the rainy season, the garbage is flattened and compacted mainly by the 220 bulldozer, and the average compaction density reaches 0.7-0.9T / M 3 . A landfill site averages 600,000 tons of waste per year, and about 250,000 tons of waste in summer, requiring a storage capacity of 313,000 M 3 ; 350,000 tons of garbage in the dry season, requiring a storage capacity of 350,000 M 3 .

[0012] Plan several parallel garbage dams in the landfill area according to the annual garbage volume. One or more garbage dams can be built according to the annual amount of garbage and the current situation of the site. The first garbage dam can be enclosed with the side embankment of the landfill area, and the formed reservoir area can be used as a landfill partition. The garbage dams built in the previous year are enclo...

Abstract

The invention relates to a summer garbage landfill process, which is characterized in that according to the amount of garbage entering the site throughout the year and the amount of garbage in the rainy season and dry season, the storage capacity required for the garbage landfill in the rainy season is calculated, and the garbage embankment dam is built by using the non-rainy season garbage with a small water content , to enclose the landfill area in the rainy season; covering the garbage with HDPE film can reduce its exposed area and realize the diversion of rainwater and leachate in the operation area; ensure that the garbage in the dry season and the garbage in the rainy season are clearly separated and minimize the road subsidence caused by garbage settlement. And reduce the occupation of storage capacity.

Description

technical field [0001] The invention relates to a summer landfill process method for municipal domestic garbage. Background technique [0002] At present, the treatment of municipal solid waste mainly includes landfill, incineration, composting and other treatment methods; according to the construction method and topography of the landfill, it can be divided into valley type landfill and flat land type landfill; and flat landfill type It can be divided into above-ground type, underground type, and semi-above and semi-underground type. [0003] Due to the lack of scientific and practical sanitary landfill technology in the rainy season, domestic landfills are divided randomly. Especially in the rainy season, the roads in the landfill area are soft, vehicles are difficult to drive, and they are easy to break down; it is difficult to unload garbage; leachate and Rainwater cannot be diverted, resulting in a large amount of leachate and high operating costs; the leachate stagnan...
