Description
Technical Field
The invention relates to the technical field of construction waste regeneration treatment devices, in particular to a mobile crushing and screening integrated machine.
Background
Construction waste is solid waste generated during the process of building construction, reconstruction, extension or demolition. According to different generation sources of the construction waste, the construction waste and the demolished construction waste can be divided. The construction waste is solid waste generated in new construction, reconstruction or extension projects, and the demolition construction waste is construction waste generated in demolition and demolition of buildings.
The construction waste has a wide erosion effect on our living environment, and if the construction waste is subjected to a long-term regardless attitude, the construction waste has adverse effects on urban environmental sanitation, living conditions, land quality assessment and the like. Firstly, after a large amount of construction waste is stacked in the land, the quality of the soil can be reduced, and the production capacity of the soil can be reduced; the construction waste is stacked in the air, so that the air quality is influenced, and some dust particles can be suspended in the air and are harmful to the health of human bodies; in the stacking process of the construction waste, the long-term stacking means that harmful substances of the construction waste permeate into underground water areas to pollute water environment; if the construction waste is piled up in the city, the urban environment and the attractiveness are not favorable; the building rubbish stacking may have some potential safety hazards, and some accidents may happen at any time.
The site selection of most urban building garbage stacking places is random to a great extent, and a great number of potential safety hazards are left. The construction site is often a temporary storage site for construction wastes, and due to the fact that construction is convenient and due protective measures are lacked, the construction wastes are collapsed under the influence of external factors, and the phenomenon that roads are blocked and even other buildings are rushed is caused. In suburbs, pits, ponds and ditches are the first-choice stacking places for building garbage, so that the storage capacity of water bodies is reduced, and the ground drainage and flood discharge capacity is reduced.
Leachate or leachate, which is the sewage from the soaking of the groundwater, can cause serious pollution of the surrounding surface water and groundwater. The pollution ways of the garbage piling site to the surface water body mainly comprise: the garbage is scattered in a pond and a ditch near a stacking field in the process of carrying; overflowing leachate of the garbage storage yard on the ground surface and flowing into a ground surface water body; leachate in the landfill can seep into nearby surface water in the soil layer. The influence of the garbage dump on the underground water is mainly that garbage pollution permeates into the aquifer along with leachate, and then deep pollution is caused by the permeation of the garbage polluted rivers, lakes, pits into the aquifer for supplying. The landfill leachate contains a large amount of organic pollutants, metal and nonmetal pollutants, and the water quality components are complex. Once drinking such contaminated water, it will cause great harm to human body.
Most of the construction wastes in China are treated in a landfill mode, however, in the stacking process of the construction wastes, under the action of temperature, moisture and the like, some organic substances are decomposed to generate harmful gases, for example, the waste gypsum of the construction wastes contains a large amount of sulfate ions, the sulfate ions can be converted into hydrogen sulfide with smelly eggs under the anaerobic condition, the waste paper boards and the waste wood can dissolve out lignin and tannic acid under the anaerobic condition and decompose to generate volatile organic acid, and the harmful gases can pollute the atmosphere when being discharged into the air; bacteria and dust in the garbage drift with wind to cause air pollution; a small amount of combustible building waste can generate toxic carcinogenic substances in the burning process, so that secondary pollution to air is caused.
The phenomenon that garbage and people compete for land is a serious step, most suburban garbage dumps are mainly piled in the open air, after long-term exposure to the sun and rain, harmful substances in the garbage (including polycyclic aromatic hydrocarbon structuring substances released by paint, coating, asphalt and the like in urban building garbage) permeate into soil through garbage leachate, so that a series of physical, chemical and biological reactions occur, such as filtration, adsorption and precipitation, or are absorbed by plant roots or are synthesized and absorbed by microorganisms, so that the suburban soil is polluted, and the soil quality is reduced.
In addition, under the action of various external forces, small broken stones of the urban building garbage piled in the open air can also enter the nearby soil, so that the material composition of the soil is changed, the structure of the soil is damaged, and the productivity of the soil is reduced. In addition, the content of heavy metals in the urban building waste is high, and the urban building waste can generate chemical reaction under the action of various factors, so that the content of the heavy metals in the soil is increased, and the content of the heavy metals in crops can be increased. Polluted soil generally has no natural self-cleaning capability, and the pollution degree is difficult to reduce by a dilution and diffusion method, so that a method for modifying the soil with huge cost must be adopted to solve the problem.
The crusher and the sieving machine are widely applied to various departments such as mines, smelting, highways, railways, water conservancy and the like. Most of mobile crushing equipment and screening are used in water conservancy aspects such as mines and buildings, but at the present stage, the treatment of the construction waste needs to be carried to a construction waste treatment plant for recovery and treatment, and the current technical means is that the construction waste is crushed and then carried to a recovery place for treatment, however, reinforcing steel bars and the like doped in the construction waste cannot be directly separated after being crushed, so that the recovery cost of the construction waste is increased.
