A two-step process of low temperature carbonization and high temperature activation was used to treat typical medical waste salt,and inorganic salt and activated carbon materials were recovered successfully.The organic matter in the waste salt was converted into insoluble residual carbon slag in low temperature carbonization section,which could be separated from inorganic salts by simple dissolution and filtration.Activated carbon material could be obtained by activating residual carbon residue as carbon precursor.The components of waste salt were analyzed by atomic fluorescence spectrometry and gas chroma-tography mass spectrometry.The activation energy of waste salt incineration was calculated by Friedman method and Starink method.The carbonization conditions of waste salt at low temperature were optimized by pipe furnace simulation test.The carbon residues were KOH impregnation method to prepare activated carbon.The results showed that the removal rate of dissolved organic carbon in the waste salt reached 99.98% under the conditions of air atmosphere,350 ℃ and 60 min,and the obtained inorganic salt products met the requirements of GB/T 6009—2014“Industrial anhydrate Sodium Sulfate” class Ⅲ.The adsorption capacity of activated carbon for methylene blue reached 762.86 mg/g.
