Problems solved by technology

[0004] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a comprehensive treatment and disposal process of solid waste building materials, through the recombination design of the treatment and disposal of urban sludge, river sludge and construction waste, the sludge in the sludge Toxic and harmful components are solidified and burned to completely reduce the possibility of secondary pollution of pollutants; three new methods of disposal of solid waste that can only be landfilled have been opened up, and the reduced amount of landfill can greatly reduce the impact on land resources. demand, turn the original useless waste into treasure, and realize the resource utilization of waste

Embodiment 1

[0022] Town sludge, river silt and construction waste are processed separately and then crushed and screened as raw materials → mixed → aged → billet making → stacking → kiln sintering → cooling and storage; the specific implementation steps are as follows:

[0023] Crushing and screening of raw materials: crushing and screening the sludge regeneration fuel, mud cake fine powder and ultrafine powder formed after urban sludge, river sludge and construction waste are processed, mud cake fine powder and construction waste The superfine powder constitutes the sintering material, and the sludge regeneration fuel is used as the fuel;

[0024] Mixing: Mix the crushed and screened mud cake fine powder, ultra-fine powder of construction waste and sludge regeneration fuel, and transport the mixed mixture to the aging warehouse;

[0025] Aging: The mixture is aged in the aging warehouse, so that various raw materials can be fully infiltrated and contacted, and the aging time is 36-40h; ...

Embodiment 2

[0031] The mud cake fine powder is: 35%-40%, the superfine powder of construction waste is: 35%-40%, the sludge regenerated fuel is: 21%-30%, and the weight of the above components is The sum is 100%.

Abstract

The invention relates to a solid waste building material comprehensive treatment and disposal process, which comprises the following process steps: respectively processing urban sludge, river sludge and construction waste, crushing and screening the raw materials, mixing, aging, making blanks, stacking the blanks, sintering in a kiln, cooling and warehousing; according to the invention, the treatment and disposal of the urban sludge, river sludge and construction waste are recombined and designed, toxic and harmful components in the sludge are solidified and subjected to combustion treatment,the possibility of secondary pollution of pollutants is completely reduced, and three new methods of solid waste treatment and disposal with only landfill are opened up. The reduced landfill volume can greatly reduce the demand for land resources, the original useless waste is changed into valuables, and the resource utilization of waste is realized. The process has the advantages of small equipment investment, large production capacity, low operation cost and high cost performance, and can realize centralized treatment of various solid wastes, realizes the integration of multiple wastes, multi-industry chain production, and finally realizes preparation of building materials from the solid wastes.

Description

technical field [0001] The invention relates to the field of urban waste treatment and disposal, in particular to a comprehensive treatment and disposal process of solid waste into building materials. Background technique [0002] As the country pays more and more attention to environmental protection, the country has successively issued a series of related environmental protection policies. Urban sludge, river silt, and construction waste are persistent diseases that have plagued urban environmental governance for a long time. At present, the main treatment method of urban sludge in my country is the landfill method. This method requires relatively little investment, but it needs to occupy land. At the same time, there are many harmful substances in the sludge that have not been eliminated for the time being. When it is directly buried, it needs to invest in waterproof and anti-seepage construction. Otherwise, it will cause secondary pollution to the environment and groundwa...
