Abstract

The invention relates to the field of waste treatment and resource utilization, and discloses a waste activated carbon and waste organic solvent synergistic harmless resource utilization treatment method which comprises the following steps: mixing waste activated carbon and a waste organic solvent, grinding into activated carbon slurry of an organic solvent, mixing the activated carbon slurry of the organic solvent, coal and a coal water slurry additive, grinding into multi-source synthetic slurry, feeding the multi-source synthetic slurry and oxygen into a coal water slurry gasification furnace together, and reacting to generate liquid slag and synthetic gas mainly containing H2 and CO. According to the treatment method, harmful substances can be effectively prevented from escaping to theenvironment in the treatment process of the waste activated carbon and the waste organic solvent, secondary pollution can be prevented, and harmless treatment on the waste activated carbon and the waste organic solvent is achieved.

Description

technical field [0001] The invention relates to the fields of waste treatment and resource utilization, in particular to a method for synergistic and harmless resource utilization and disposal of waste activated carbon and waste organic solvents. Background technique [0002] Activated carbon is a material with a special structure and performance among carbonaceous materials. It has a large specific surface area, numerous pores, and abundant oxygen-containing functional groups on the surface. Thanks to this unique physical and chemical properties, it is usually used as an adsorbent in energy development, Manufacturing and "three wastes" treatment and other fields play an important role. After repeated regeneration, the activity of activated carbon is reduced, it is difficult to recycle, and it is listed as hazardous waste (HW49). Organic solvents (phenols, aldehydes, ketones, esters, alcohols, etc.) are widely used in the pharmaceutical, chemical and clothing industries due...
