Description
Technical Field
The invention relates to the technical field of environmental protection, in particular to a household garbage drying and screening device.
Background
With the continuous deepening of the urbanization process, the production amount of the household garbage reaches astronomical numbers. The components of the household garbage are complex, and the generated stink and leachate cause great harm to soil, atmosphere and water sources. At present, the domestic garbage treatment mainly depends on landfill and incineration. Landfill not only occupies a large amount of land, but also leachate treatment and later soil remediation, as well as damage to the surrounding environment, bring about a series of environmental problems. Incineration is a treatment method advocated by the nation at present, but because the classification of domestic garbage is not thorough and the water content is very high, a large amount of heat energy is consumed in the combustion process, and simultaneously, the generation of dioxin causes more harm to the atmosphere.
As the household garbage inevitably has part of kitchen garbage mixed into dry garbage, the garbage is putrefactive due to the existence of moisture and organic matters in the stacking and transferring processes to generate stink and the sewage flows transversely. And the sewage can contaminate the dry waste resulting in all waste being smelly. The continuous decay of organic matters can generate more permeable organic matters such as mercaptan and the like, so that garbage transfer stations and treatment plants are all full of pungent and difficult-to-clean garbage smell. All the sources of the organic matters are that organic matters in the garbage are not timely and effectively controlled, stored and digested.
In recent years, comprehensive treatment methods for domestic garbage are proposed and practiced, and the items are that mixed garbage transported from a municipal area by a compression garbage truck is classified and sorted by large-scale sorting pretreatment equipment near a garbage landfill, and part of plastics and metals are sorted out. But the garbage is extruded and crushed during the transportation process and is mutually contaminated. The sorted plastics have very low value for recycling. The cost and the income of the method are greatly different, and the method is mainly maintained by mass subsidies of the government and is difficult to popularize and popularize.
