Problems solved by technology

At present, most of the non-recyclable garbage disposal methods are in the traditional way of stacking and landfilling, occupying tens of thousands of acres of land; moreover, insects and flies fly around, sewage overflows, and the smell is smoky, seriously polluting the environment

Embodiment 1

[0025] (1) Metal recovery:

[0026] Put the non-recyclable garbage into the crusher for processing, process it into a particle size of 5-10cm, and then pass through the belt with magnets to recycle the metal in it. The recovery rate is 5%. The crushed garbage is soaked in water and squeezed out. machine, with a water content of 40%, squeezed dry for later use.

[0027] (2) Separation of organic matter and inorganic matter:

[0028] The crushed material obtained in step (1) is transported to the flotation device, the device is filled with water in advance, and H is added in proportion to the mass of the water 2 o 2 and NaOH to obtain a NaOH concentration of 0.05%, H 2 o 2 The concentration is 1%. After stirring and standing still, the floating matter in the upper layer is organic matter, and the lower layer is inorganic matter. The organic matter and inorganic matter are separated and dried.

Abstract

The invention provides a method for manufacturing a hollow brick by using non-recyclable waste. The method comprises the following steps: firstly, crushing the non-recyclable waste and then passing through a belt with a magnet to recover metals; separating and drying organic matters and inorganic matters in the crushed non-recyclable waste in a flotation device; finally crushing the obtained inorganic matters and organic matters, mixing the inorganic matters, the organic matters and cement, adding water and stirring into slurry; putting into a mold, and carrying out vibration molding or pressure molding; and carrying out natural curing to form a hollow brick product. Compared with a traditional hollow brick, the hollow brick produced by the method has the advantages that all performance indices are improved at different extents; meanwhile, the hollow brick is simple in preparation process and high in practicability; a traditional treatment method for stacking and filling the non-recyclable waste is changed; consumption of soil resources and emission of toxic and harmful substances are reduced; and cyclic utilization of resources is achieved on the bases of environment protection and energy conservation.

Description

technical field [0001] The invention belongs to the technical field of resource recycling and comprehensive utilization, and relates to a method for manufacturing hollow bricks by using non-recyclable garbage. Background technique [0002] With the rapid development of my country's social economy, the acceleration of urbanization and the rapid improvement of people's living standards, the garbage generated in the process of urban production and life has also increased rapidly. Domestic garbage occupies land, pollutes the environment, and affects people. Health effects are also becoming more apparent. The massive increase of municipal solid waste has made it more and more difficult to dispose of waste, and the resulting environmental pollution and other issues have gradually aroused widespread concern from all walks of life. The treatment of domestic waste technology selection often becomes a difficult problem in municipal solid waste treatment. [0003] Garbage sorting and ...
