Abstract

The invention belongs to the technical field of garbage landfill, particularly relates to a landfill gas horizontal collection well and application thereof, and aims at solving the problems that an existing landfill gas collection well is low in gas collection efficiency on landfill gas, and pipelines are prone to being blocked. The landfill gas horizontal collection well is obliquely placed in a groove formed in a garbage heap, the groove is filled with gravel, and penetrating fluid in the garbage heap enters solid pipes through perforated pipes via gravel filtering and then flows out of the garbage heap through a third pipeline. A first pipeline assembly and a second pipeline assembly are laid approximately horizontally. Landfill gas is extracted at the high end of the third pipeline and / or the high end of the second perforated pipe through the gas collection device. The landfill gas horizontal collection well is flexible to use and good in drainage effect; pipelines are not prone to being blocked; later maintenance work is low; the situation that gas extraction cannot be achieved when an existing single-pipe horizontal well is blocked is avoided; and the gas collection efficiency on the landfill gas is improved.

Description

technical field [0001] The invention belongs to the technical field of garbage landfill, in particular to a horizontal collection well for landfill gas and its application. Background technique [0002] Landfill gas refers to the gas generated by anaerobic digestion and degradation of a large amount of organic matter contained in the accumulated or landfilled municipal solid waste in the landfill site. The main components of landfill gas are methane and carbon dioxide. Methane is a flammable and explosive gas with potential explosion hazards. The greenhouse effect produced by methane will have a great impact on the global environment. In addition, landfill gas contains a small amount of toxic gases, such as hydrogen sulfide and ammonia mercaptan, which are harmful to humans, animals and plants. Landfill gas can also affect the quality of groundwater. The dissolved carbon dioxide in the water increases the hardness and mineral content of groundwater. It can be seen that la...
