After it adsorbs a lot of impurities, it can be desorbed. That is, after removing the impurities adsorbed on the surface and pores of the activated carbon, the adsorption capacity of the activated carbon can be restored so that it can be reused. To extend the service life, the current activated carbon desorption methods include thermal desorption, solvent desorption, steam desorption, gas desorption and photodesorption, among which thermal desorption refers to the desorption of substances adsorbed on the granular activated carbon due to thermodynamic action by increasing the temperature.
