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
The invention discloses the device that a kind of recycling garbage emission accelerates landfill waste decomposition, belong to field of garbage disposal.
Background technology
Along with the rapid raising of the fast development of Chinese society economy, the quickening of urbanization process and living standards of the people, city produces and also increases sharply with the junk that produces in life process thereupon, the situation of house refuse land occupation, contaminated environment and also all the more obvious on the impact of health of people.Rolling up of domestic waste, make garbage disposal more and more difficult, the problems such as resultant environmental pollution cause the extensive concern of various circles of society gradually.Country pays much attention to environmental protection problem; tremendous development is obtained in house refuse and sewage preventing and controlling; but; China's municipal refuse output is ever-increasing while; the classification of house refuse; to reclaim and disposal ability and levels relatively lag behind; namely China's Prediction for Solid Waste Treatment Technology is very weak; therefore the applicability of the technology of domestic rubbish disposal becomes the very important problem solving house refuse, and the process of the house refuse choice of technology often becomes a difficult problem for a urban garbage disposal.
The mode of the main disposal of refuse of current China has two kinds, is respectively sanitary landfills and high temperature incineration.First sanitary landfills is the effective ways of municipal refuse of dissolving in a large number, also be the final processing method of all garbage treating process residues, China generally adopts direct landfill method, so-called direct landfill method is inserted by rubbish in ready hole to cover compacting, make it that biology occur, physics, chemical change, decomposing organic matter, reach minimizing and innoxious object, but this method causes garbage disposal overlong time, general landfill just can renovate a rubbish for up to 50 years, and the method also exists the permanent shortcoming taking a large amount of soil, when a soot uses a period of time just to open up new refuse landfill again, if things go on like this, refuse landfill constantly increases, cause the significant wastage of land resource.Secondly high temperature high temperature incineration method is that rubbish is placed in high temperature furnace, make a kind of method that wherein combustible component is fully oxidized, the heat produced is used for generating and heating, thermal energy can be steam by the high temperature on incinerator surface simultaneously, may be used for the fermentation such as heating installation, air-conditioning equipment and steam turbine power production.But the method contains some metal due to rubbish, burn and there is very high toxicity, the carcinogens such as easy generation dioxin and to environment produce secondary harm, and the calorific value of rubbish is large especially when process, otherwise must add combustion adjuvant, operating cost is increased to the unaffordable stage in general city.
Summary of the invention
