Embodiment 1

[0068] 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:

[0069] Table 1: Composition of MSW

[0070]

[0071] 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 heavy metal ion adsorbent. The adsorbent is prepared by modifying a carbon material obtained through pyrolysis carbonization of municipal solid wastes, and the heavy metal ion adsorbent has a higher adsorption capacity and better regeneration stability.

Description

technical field [0001] The invention belongs to the technical field of adsorbents, in particular to a heavy metal ion adsorbent. Background technique [0002] Heavy metal ions are the most serious environmental pollution and most harmful substances to human beings. Most metal ions and their compounds are easily absorbed by suspended particles in the water and precipitated in the sediment layer at the bottom of the water, polluting the water body for a long time. Certain heavy metals and their compounds can accumulate and accumulate in fish and other aquatic organisms and crop tissues, and participate in the biosphere cycle. After drinking, the toxicity is amplified and combined with other toxins in the water to form more toxic organic substances. [0003] 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 ad...
