Abstract

The invention discloses an active carbon regeneration treatment method, and belongs to the field of environment protection. Some organic matters in rest sludge are mainly adsorbed from adsorption saturated active carbon; through enzymolysis, some active substances are extracted from the organic matters; useful resources can be recovered; the enzyme activity can be improved through the microbe decomposition; the generation of new active substances is stimulated, so that the organic matters in the rest sludge can be decomposed in an accelerated way; the regeneration speed of the active carbon isimproved. The active carbon regeneration treatment method solves the problems that the existing active carbon regeneration treatment time is long; the regeneration efficiency is low; the resource waste is caused by waste active carbon.

Description

technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to a treatment method for activated carbon regeneration. Background technique [0002] Activated carbon regeneration is the reactivation of fully adsorbed activated carbon after being treated under certain conditions. Activated carbon, also known as activated carbon black, is one of the commonly used adsorbents and is widely used in various industries. Activated carbon has strong physical adsorption and chemical adsorption functions. Its adsorption performance is largely determined by its pore structure characteristics. The pore distribution of activated carbon is three-dispersed, that is, macropores, mesopores and micropores all account for a certain proportion. At present, activated carbon is basically made of wood, coal, or petroleum semi-finished products, which consumes a lot of cost and the preparation process is complicated, which is not conducive to sus...
