Abstract

The invention discloses an on-site ectopic enhanced aerobic stabilization method for a household garbage landfill, and belongs to environmental engineering. According to the method, the staged stepwise excavation is adopted, and the operation can be performed synchronously or in stages, so that the operation progress is guaranteed and the operation efficiency is improved; the material sorting is performed on excavated stale garbage, so that the resource utilization and the safe treatment of the garbage can be realized; and therefore, the landfill amount of the stale garbage is reduced, the space utilization efficiency of the household garbage landfill is improved, the oxidation rate of sorted muck is improved in a natural drying or forced ventilation mode, and the muck stabilization time is shortened. The sorted muck is subjected to backward stepwise backfill, so that the stability of the landfill is improved, the stabilization rate of the stale garbage is accelerated, the sanitary environment of the landfill is improved, and the requirement on special equipment is low; and the method is applicable to fast stabilization and restoration engineering for the simple household garbage landfill.

Description

technical field [0001] The invention discloses an aerobic stabilization method for in-situ in-situ intensification of domestic garbage landfills, which belongs to the category of environmental engineering. Background technique [0002] According to statistics, there are currently more than 3,519 simple landfills in my country, accounting for 29% of the total number of domestic waste landfills in the country, which urgently need to be repaired. Moreover, as of 2010, 34% of the 935 municipal solid waste landfills across the country were not impermeable, and 26% were not checked for environmental protection. In the same year, more than 10 simple landfill pollution incidents occurred in Xi'an, Shenzhen and other places. A large number of simple landfills seriously threaten the safety of the surrounding environment and need to be repaired urgently. [0003] The construction cost of modern domestic waste landfill is high, and the site selection is harsh, which has seriously rest...
