Disposal Methods of Domestic Waste
The disposal methods of domestic waste include landfill, incineration and composting.
- Incineration treatment: The incineration method is a method of placing garbage in a high-temperature furnace to fully oxidize the combustible components in it, and the generated heat is used for power generation and heating.
2. Composting treatment: pile the domestic garbage into piles, keep the temperature at 55~70℃ for storage and fermentation, and decompose the organic matter into inorganic nutrients with the help of the ability of microorganisms in the garbage to decompose. After composting, household waste is turned into hygienic, odorless humus.
The domestic garbage sorting machine is actually equivalent to a garbage processing assembly line. There are different machines on this assembly line responsible for sorting and recycling different garbage. After the domestic garbage is sent to the assembly line, each machine processes the garbage, and finally Garbage is classified according to different categories such as plastic, organic matter, paper shell, glass, metal, inorganic matter, etc. to realize the utilization of garbage resources
The domestic waste needs to go through the harmless treatment process of the system. Usually, the plate feeder and the transfer belt conveyor feed the domestic waste into the coarse crushing hopper of the waste sorting and pretreatment system. When the bag is broken, the particle size of the material is crushed to Below 250mm, the domestic garbage crushed by the primary crusher is transported to the drum screen by the transfer belt conveyor, and the iron remover is set on the transfer belt conveyor. Magnetic separation working state is closed. The trommel screen sorts the domestic waste into two kinds of materials larger than 80mm (overscreen) and underscreen.
The material on the trommel screen is transported to the air separator, which is separated by the air separator to screen out light and heavy substances. Heavy substances (stone, glass, concrete, etc.) are transported to designated locations for landfill; light substances (paper, plastic combustibles) enter the secondary crusher, and iron (magnetic substances) substances are sorted out by the iron remover, and the remaining materials are made into into waste-derived fuel RDF fuel.
