The advantages of landfill waste: Because of its mature technology and low treatment costs, sanitary landfill is the main way of centralized disposal of urban waste in China, which can reduce pollution to the environment, and parks and stadiums can be built on the landfill site.
The disadvantages of landfill waste: slightly less investment, simple process, large processing capacity, and better achieve the harmless surface.
However, the green waste landfill is not harmless treatment, residual a large number of bacteria, viruses; There are also hidden dangers such as biogas heavy metal pollution; Its garbage leakage will also pollute groundwater resources for a long time, so this method has great potential harm and will bring endless future problems to future generations.
Not only does this approach fail to recycle the waste, but it also takes up a lot of land and leaves a dangerous source of pollution for future generations.
Many developed countries now ban landfills.
The competent departments at all levels of our government have gradually realized the problems existing in this processing technology and are bound to prohibit and eliminate such behavior.
landfill landfill dumps are processed in a sealed and dustproof room with reasonable design and compact structure. Conveyor, sorter, shredder, tower screen, dryer and other production line equipment landfill seamlessly connect to make the whole production line more orderly.
Domestic waste - automatic sorting of ferrous metals → inorganic sorting/mashing - Extraction of non-ferrous metals → secondary crushing/secondary removal of inorganic substances → U-type winching input/high-pressure air output → stirring/killing → Drying → pile drying → recycled particles (combustion rod)→ automatic metering and packaging → storage.
Fully enclosed, mechanized garbage sorting equipment, also known as garbage sorting equipment and garbage sorting and processing equipment, is mainly used for garbage sorting. The waste can be divided into six categories: first, inorganic substances (such as brick tiles, etc.), after being selected, building materials can be made; Second, non-recyclable fuels enter the pyrolytic gasification system to provide heat energy for the factory; Third, organic materials, sandy soil, natural fermentation after the production of nutrient soil or organic fertilizer; Four are plastics, wood-plastic panels or plastic particles, and five are ferromagnetic materials, mainly recycled. The above 6 types of materials enter the corresponding treatment system respectively to achieve the comprehensive treatment of municipal solid waste.
landfill consists of garbage storage bin and lifting loading, crushing, screening, wind separation, specific gravity separation, magnetic separation and transfer. Landfill sorts all kinds of garbage into inorganic, organic, combustible, plastic, ferromagnetic and other recycled materials and sends them into the next system for harmless comprehensive treatment and resource cross-reuse.
