영문 초록

This work experimentally determined the effect of microaerobic condition on anaerobic digestion of thickened waste activated sludge in semi-continuous mesophilic digesters at hydraulic retention time of 20 days. The concentration of hydrogen sulfide was 7±2 ppm at the microaerobic condition and 14±2 ppm at the anaerobic condition. Removal efficiency of volatile solid was not significantly different between microaerobic (40±8%) and anaerobic (38±8%) conditions. There was no important difference between microaerobic (1,352±98 ml/d) and anaerobic (1,362±104 ml/d) conditions in the biogas production, either. Therefore, it could be concluded that the application of the microaerobic condition was an efficient method of the hydrogen sulfide removal from the biogas.
