Abstract

The invention relates to a cooperative treatment method and device for garden solid waste and building solid waste. The treatment method comprises the following steps: S1, sorting the garden solid waste at first to obtain leaves and branches; squeezing the leaves to obtain squeezed liquid and squeezed residues; S2, sorting the building solid waste to obtain wood components and inorganic components; S3, mixing and breaking the branches and the wood components, and then carrying out pyrolysis carbonization treatment to obtain biochar; mixing the biochar with the squeezed liquid, and heating to obtain loaded modified biochar; and S4, breaking the inorganic components, screening residual materials subjected to magnetic separation to obtain fine lime soil with the size of less than 1mm, and mixing the fine lime soil with the loaded modified biochar to obtain mixed modified nutrient soil. According to the invention, the high-quality modified nutrient soil is produced through cooperative treatment for the garden waste and the building waste, the problems that garden branches are rapidly reduced, tree leaf compost is difficult to decompose, the fine lime soil of buildings is difficult to use and the like are solved, the concepts of circular economy and clean production are fully embodied, and good economic benefits and environmental benefits are achieved.

Description

technical field [0001] The invention belongs to the technical field of garden solid waste and building solid waste treatment, and in particular relates to a method and device for collaborative treatment of garden solid waste and building solid waste. Background technique [0002] With the rapid development of economy and society, people have higher and higher requirements for living standards and quality. my country's urbanization process is accelerating rapidly, and the scale of urban housing construction is expanding day by day. A large amount of construction waste is continuously produced, causing a lot of inconvenience to people's lives. During the process of urbanization and urban renewal, a large amount of abandoned construction sludge and solid waste will be generated. These construction wastes are the main components of urban waste, accounting for about 30%-40% of the total urban waste. The stacking and landfilling of construction waste not only encroach on a large ...
