With the continuous development of urbanization, a large amount of construction garbage and domestic garbage are randomly stacked, not only occupying land, but also polluting the environment, and directly or indirectly affecting air quality. At present, most of the construction waste and domestic waste in China are disposed of in landfills. However, during the storage of construction waste and domestic waste, under the action of temperature and moisture, certain organic substances are decomposed to generate harmful gases, such as construction waste. Gypsum contains a large number of sulfate ions. Under anaerobic conditions, sulfate ions will be converted into hydrogen sulfide with a smell of rotten eggs. Waste cardboard and waste wood can dissolve lignin and tannin under anaerobic conditions and decompose to generate volatilization. Organic acids, this harmful gas will pollute the atmosphere when it is released into the air; bacteria and dust in the garbage will drift with the wind, causing pollution to the air; a small amount of combustible construction waste and domestic waste will produce toxic carcinogens during the incineration process Substances, causing secondary pollution to the air. Board and waste wood can dissolve lignin and tannic acid under anaerobic conditions and decompose to generate volatile organic acids. This harmful gas will pollute the atmosphere when it is released into the air; bacteria and dust in the garbage will drift with the wind, causing Air pollution; a small amount of combustible construction waste and domestic waste will generate toxic carcinogens during incineration, causing secondary pollution to the air. China's current construction waste and domestic waste recycling has a certain technical basis, both in laboratory research and market applications have achieved certain results. For example, after sorting, removing or crushing many wastes in construction waste, most of them can be reused as renewable resources, such as waste steel bars, waste iron wires, waste wires, and various scrap steel parts. They are sorted, concentrated, and returned to the furnace. After that, it can be processed into various specifications of steel; waste bamboo wood can be used to make artificial wood; brick, stone, concrete and other waste can be crushed to replace sand for masonry mortar, plastering mortar, Concrete cushion, etc. can also be used to make building materials such as blocks, paving bricks, and grate bricks. To sum up: construction waste is a misplaced resource. The treatment and reuse of construction waste and domestic waste is already the top priority of our country in the study of solid waste treatment, and it will push the Construction Waste crusher to a healthy development path to achieve Urban construction waste reduction, recycling and harmless treatment, turning waste into treasure.
