Description

Kitchen waste recovery equipment

Technical Field

Background

With the improvement of the living standard of residents and the rapid development of the catering industry, the discharge amount of kitchen waste is increased day by day. The kitchen waste refers to food waste and food residues in families, schools, public dining halls of institutions and catering industries, is a main component of municipal domestic waste, has four high characteristics of high oil content, water content, salt content and organic matter content compared with other waste, is extremely easy to decay and deteriorate, emit stink, and easily generate pathogenic microorganisms, and needs to be quickly and effectively treated, otherwise, the kitchen waste can cause serious pollution to the environment.

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. In the processes of storing, collecting, transporting and landfill of the kitchen waste, because the water content and the organic matter content are high, the kitchen waste is easy to rot and smell in a short time and breed mosquitoes, flies and the like, and the surrounding environment is greatly polluted.

In addition, the disposal method of the municipal refuse usually comprises incineration and landfill, and if the incineration mode is adopted for disposal, because the moisture content of the kitchen waste is very high, the incineration furnace can be caused to burn insufficiently to generate dioxin; if the treatment is carried out in a landfill mode, the mixed kitchen waste is also not suitable for treatment due to 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.

In conclusion, how to treat kitchen waste in a practical, efficient and green way is a problem to be solved urgently.
