RESEARCH ON THE REGENERATION OF ACTIVATED CARBON USED FOR SEWAGE ADSORPTION BY FLUIDIZED BED

Liu Shou

Abstract

The powder activated carbon used for sewage adsorption was regenerated by fluidized bed system. The effect of temperature, composition of active gas, moisture, retention time and the rate of feeding stuff on the adsorption capacity and loss of regeneration of activated carbon were systematically studied. The optimal condition of fluidized bed regeneration of powder activated carbon was determined: temperature of combustion chamber 1?207?℃, temperature of fluidized bed 677?℃, fluidized rate 0.256?m/s, rate of feeding stuff 3.34?kg/h, oxygen percentage of active gas 0.69?%.
