Description
Technical Field
The invention relates to the technical field of garbage treatment, in particular to a garbage recycling treatment process.
Background
Along with the rapid development of the socioeconomic rapid progress of China and the rapid improvement of the living standard of people, the garbage generated in the urban production and living process is rapidly increased, and the domestic garbage occupies land, pollutes the environment and has more obvious influence on the health of people. Specifically, the waste has caused a great hazard: organic matters are rotten, compounds are decomposed, ammonia, hydrogen sulfide, odor and other toxic and harmful gases are emitted, and the atmosphere is polluted; viruses, flora, ova and the like are propagated, bred and spread; pollutants permeate into the stratum along with sewage and flow into a river channel to pollute the land and an underground water system; the metals and their compounds are resolved or ionized, and pollute water and land. The garbage is classified into industrial waste garbage, mining waste garbage, municipal waste garbage, agricultural waste garbage, radioactive waste garbage and the like according to the source. Wherein the municipal solid waste is also called municipal refuse; the production amount of organic solid waste garbage such as organic components, fruit and vegetable garbage, livestock and poultry manure, straw and the like in urban garbage of urban residents is continuously increased, the proportion of the garbage in the household garbage is high, and huge pressure is brought to the collection, transportation and treatment of the current urban household garbage.
The great increase of garbage makes the garbage treatment more and more difficult, and the problems of environmental pollution and the like caused by the increase of garbage gradually attract the wide attention of all social circles. In China, to realize the industrialization, resource utilization, reduction and harmlessness of garbage, mixed collection, low content and heat value of recyclable materials, and high water content and biodegradable organic content of the garbage must be faced. In response to these problems, various techniques are also applied.
The first is incineration, the traditional garbage treatment generally adopts incineration or crushing recycling, the incineration method directly carries out unified incineration treatment on the garbage, the incineration has the advantages that the generated heat energy can generate electricity and heat, the treatment speed is high, the defects are that a plurality of toxic and harmful substances can be generated, such as rubber plastics or waste oil and other high molecular organic compounds can generate a large amount of toxic gases in the incineration process, such as toluene, fluorocarbon derivatives, dioxin, sulfur dioxide and the like, and the pollution is caused to the atmosphere, water, soil and plants.
The second is deep burying, and the advantage of deep burying is convenient economy, can compress the rubbish shaping, buries underground at a certain degree of depth, and although the foundation ditch has taken waterproof impervious isolation measure, many high molecular polymer degradation need very long time, still can wrap up and hold many bacterial virus in the deep burying process.
The third is to make compost, but may cause the transfer and diffusion of pollutants, especially heavy metal pollutants, to directly pollute farmlands and plants.
If the garbage can be recycled, the garbage disposal problem can be solved on one hand, and on the other hand, resources can be fully utilized.

In conclusion, the invention can treat garbage harmlessly by the operation, and the prepared granular substance can replace sand, wood dust and foam, can be stirred with cement, can be used as building materials, and can also be used for producing living products, such as glass fiber reinforced plastics, partition boards and heat insulation materials. According to the invention, the surface area of the garbage is increased by crushing the garbage, so that the garbage can be conveniently reacted with the additive in the subsequent process, and the garbage can be decomposed and treated better; the disodium ethylene diamine tetraacetate and tetrasodium ethylene diamine tetraacetate can perform a displacement reaction with heavy metal ions to generate a complex, so that a heavy metal trapping agent can conveniently react with the complex to generate a precipitate; the heavy metal trapping agent is added to react with heavy metal ions in the garbage and form a flocculation state in a short time, so that heavy metal substances are trapped and separated; by adding the dithiocarbamate derivative, the garbage reaction can be promoted, the heavy metal capture time is shortened, and the reaction process is accelerated; the degradation accelerator is added to promote the garbage degradation reaction and accelerate the garbage recovery treatment process; the bactericide is added, so that bacteria can be killed, and the quality of the treated garbage is ensured; by adding the diglycol, resin and grease in the garbage can be dissolved, plastics can be degraded, and heavy metals can be complexed to play a role in fixing the heavy metals; in addition, the treatment at high temperature can accelerate the plastic reaction, thereby accelerating the garbage recovery treatment speed.
The embodiments described above are some, but not all embodiments of the invention. The detailed description of the embodiments of the present invention is not intended to limit the scope of the invention as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
