Abstract:
The optimum conditions for the combined process of air stripping and photocatalysis were studied by using the activated carbon saturated with toluene as the experimental object. The influences of the series of photocatalytic device,mass ratio of catalyst-activated carbon,gas flow,the addition of activated carbon,regeneration time of activated carbon on the removal efficiency of toluene and the regeneration rate of activated carbon were investigated. The results showed that when the mass ratio of the catalyst and activated carbon was 0.4,the gas flow was 3.5 m3/h and the addition of activated carbon was 50 g,the regenerated efficiency of activated carbon saturated with toluene with light irradiation of 50 min was 82.06% and the removal rate of toluene reached 87.11%,respectively. It is also proved that the combined process of air stripping and photocatalysis can effectively regenerate the activated carbon with saturated adsorption of toluene.
