Embodiment 1

[0061] Municipal solid waste from Wuluju garbage compression and transfer station in Haidian District, Beijing was selected, and the composition of the garbage was tested as shown in Table 1 below:

[0062] Table 1: Composition of MSW

[0063]

[0064] Carry out high-temperature distillation and carbonization of the above-mentioned garbage through the following steps: After removing the dregs, glass, stones, ceramics and metals in the garbage through a garbage sorting machine such as a specific gravity sorting machine, put the garbage into the garbage transport device, and then put the garbage Pulverize; pass the garbage transport device through the high-temperature distillation carbonization device; take out the gas stream from the upper part of the high-temperature distillation carbonization device; pass the gas stream through the catalyst bed in gaseous form; condense and separate the effluent from the catalyst bed to obtain a liquid combustible material and water; carbo...

Abstract

The invention provides a reutilization method for pyrolytic carbides of municipal domestic wastes. A carbon material obtained through carrying out pyrolytic carbonization on the municipal domestic waste is modified and then is used for adsorbing heavy-metal ions. The adsorbent prepared by the method provided by the invention is low in cost and good in adsorption effect.

Description

technical field [0001] The invention belongs to the technical field of recycling of waste resources, and in particular relates to a method for reusing charcoal pyrolysis of urban domestic waste, and more particularly to a method for preparing an adsorbent by modifying the charcoal, that is, a carbon material. Background technique [0002] Activated carbon is a kind of porous carbon-containing substance, which has a highly developed pore structure and a high specific surface area, and is an excellent adsorbent. The adsorption is achieved through physical adsorption and chemical adsorption. In addition to carbon elements, its constituent substances still contain a small amount of hydrogen, nitrogen, oxygen and ash, and its structure is formed by the accumulation of hexacyclic compounds formed by carbon. Due to the irregular arrangement of six-ring carbon, activated carbon has the characteristics of multi-microporous volume and high surface area. [0003] Municipal solid wast...
