چکیده:

Bioreactors for air pollution control are expected to encounter fluctuating conditions or periods without pollutant supply. In the present study, we compare the performance of a two phase partitioning bioreactor(TPPB) and an ordinary bioreactor (OB) after being exposed to hexane starvation period. In OB, after 3 of days starvation period the removal efficiency was reduced by 99%, and about 6 days were needed to recover the initial removal efficiency when the hexane feeding resumed. In contrast, in the TPPB the hexane removal efficiency was not changed significantly andrecovered to its initial removal efficiency within 10 hours. The results of this study show that the TPPB system can effectively sustain the biological treatment of waste gas during starvation periods of hydrophobic pollutants.
