Background
The construction waste refers to the general name of dregs, waste concrete, waste bricks and stones and other wastes produced by people in the production activities of the construction industry such as demolition, construction, decoration and repair. The construction waste can be classified into engineering residue soil, decoration waste, demolition waste, engineering slurry and the like according to the production source; the construction waste can be classified according to composition, and can be divided into slag, concrete blocks, broken stone blocks, broken brick and tile blocks, waste mortar, slurry, asphalt blocks, waste plastics, waste metals, waste bamboo and wood, and the like, wherein the quantity of the construction waste in China accounts for 30-40% of the total quantity of the urban waste. Reckoning with the standard of 500-600 tons per ten thousand square meters. In 2020, the building garbage is about 300 hundred million square meters, and the newly generated building garbage is a shocking number. However, most of the construction wastes are not treated, and are transported to the suburbs or villages by construction units, and are piled or buried in the open air, so that a large amount of construction expenses such as land acquisition expenses and garbage clearing and transporting expenses are consumed, and meanwhile, the problems of scattering, dust, sand flying and the like in the clearing and piling processes cause serious environmental pollution.
In order to solve the technical problems, the invention designs a recycling treatment process for building garbage and decoration garbage, which can classify the building garbage and the decoration garbage by a crusher, a magnetic separator, a heavy-load bouncing sieve and a vibrating sieve according to the garbage types with more complex components in China at present, and finally divide the building garbage and the decoration garbage into four major products, namely recycled aggregate, mixed combustible, scrap iron and manual sorting; the recycled aggregate can be used for manufacturing recycled garden bricks and can also be used for road cushion layers, the mixed combustible can be conveyed to a burning power plant for burning, power generation and utilization, the scrap iron can be transported out for sale, and the manual sorted materials can be sold in a classified manner; in a word, the resource disposal process for the construction waste and the decoration waste is simple and reasonable in process design, easy to operate, capable of recycling the construction waste and the decoration waste in a classified manner, and capable of effectively protecting the environment.
