Kitchen waste crushing treatment device
Technical Field
The invention relates to a kitchen waste crushing treatment device, and belongs to the field of solid waste treatment in environmental protection.
Background
In the past, the kitchen waste is mainly used as a feed for raising pigs in suburbs of cities, and due to the fact that the sources of the kitchen waste are complex and the kitchen waste is rich in organic matters, a good growing and breeding environment is provided for various pathogenic microorganisms and various flies carrying the pathogenic microorganisms, and disease transmission is possibly caused, and the kitchen waste is forbidden by government regulations. In daily life, residents usually mix the kitchen waste into the household waste and send the kitchen waste to a waste collection point through a plastic bag, so that the components and characteristics of the urban household waste are changed.
During the storage, collection, transportation and garbage landfill of the kitchen waste, the kitchen waste is extremely easy to rot and smell and breed mosquitoes, flies and the like in a short time due to high water content and organic matter content, and the surrounding environment is greatly polluted. In addition, the disposal method of the municipal refuse usually comprises incineration and landfill, if the municipal domestic refuse is incinerated, because the water content of the kitchen refuse is usually as high as about 90%, the calorific value is 2100-3100 KJ/Kg, and the kitchen refuse and other refuse are incinerated together, the requirement of the calorific value of the refuse incineration power generation cannot be met, but the incinerator can be caused to burn insufficiently to generate dioxin; if the household garbage is buried, the mixed kitchen garbage is also not suitable for treatment because of high moisture content. In addition, a large amount of organic matters are wasted in incineration and landfill, so that the kitchen waste needs to be treated separately.
