In order to evaluate the independent and incorporative use of pre-treatment on solubilization efficiency and applicability as an external carbon source for denitrification, various pre-treatments methods were studied. Among the various pre-treatments, alkali-ozone pre-treatment showed the highest SDNRs and RBD COD fraction in this study. As compare with control, the concentration of SCOD was increased by approximately 77, 98 and 115 times and the SDNRs by SCOD generated from alkali-ozone pre-treatment were 4.5, 5.4 and 6.0 mg NO3-N/g MLVSS hr. Consequently, the incorporative use of pre-treatments was much more effective than other independent use of pre-treatment to both solubilization and the use of external carbon source for denitrification. |
