초록

This study was conducted to investigate the removal effect of malodorous substances of piggery wastes by air injection. With 7% of TS weight of artificial piggery wastes, this study focused on the changes of the concentration of VFAs, H2S during treatment period of 14 days. As a results of this study, air injection volume for removal of malodorants in this study was 150$m\ell$ / min$.$l$.$Under this condition, we found the concentrations of VFAs, H2S, NH3 have very high relationship with the pH, ORP, BOD, {{{{ { NH}`_{4 } ^{+ } }}-N. Especially, the concentration of Volatile Fatty Acids, one of most offensive odorants and one of BOD compounds were depended on ORP which can be controled by air injection in artificial piggery wastes.
