Problems solved by technology

[0004] The technical problem mainly solved by the present invention: In view of the problem that the decomposition time of various landfill wastes is relatively long and the waste of land resources is relatively large in the process of decomposition, a method of recycling waste discharges to accelerate landfill waste is provided. Decomposition device, which heats the garbage permeate at high temperature and then sprays it in the landfill in a circular manner. The methane generated in the landfill is introduced into the free radical oxidation box, and under the action of ultraviolet light, it undergoes photochemical reaction with nitrogen oxides. The reaction, the strong oxidizing free radicals produced are introduced into the landfill through the jet pipeline, and the landfill waste is accelerated to oxidize and decompose. The gas can be recycled and will not cause secondary pollution to the environment

Abstract

The invention relates to a device for cyclically using garbage emission to accelerate landfilled garbage decomposition, and belongs to the field of garbage processing. The device is characterized in that landfill leachate is heated at high temperature and is then cyclically sprayed into a garbage landfill field; methane generated in the garbage landfill field is introduced into a free radical oxidation box; under the effect of ultraviolet light, chemical reaction is taken with nitrogen oxides; the generated strong-oxidizing-property free radicals are guided into the garbage landfill field through a gas spraying pipeline; the oxidation decomposition of the landfilled garbage is accelerated. The method has the advantages that the operation is simple, so that the garbage decomposition time is greatly shortened; the land resource waste is reduced; the generated harmful gas is cyclically used; secondary pollution cannot be caused on environment. Practical instances prove that the landfilled garbage can be decomposed after at most three years, and the decomposition speed is accelerated by more than 99.7 percent.

Description

technical field [0001] The invention discloses a device for recycling garbage discharges to accelerate the decomposition of landfill garbage, which belongs to the field of garbage treatment. Background technique [0002] With the rapid development of my country's social economy, the acceleration of urbanization and the rapid improvement of people's living standards, the garbage and waste generated in the process of urban production and life have also increased rapidly. Health effects are also becoming more apparent. The massive increase of municipal solid waste has made it more and more difficult to dispose of waste, and the resulting environmental pollution and other issues have gradually aroused widespread concern from all walks of life. The country attaches great importance to environmental protection issues, and has made great progress in the prevention and control of domestic waste and sewage. However, while the output of urban waste in my country continues to increase,...
