Abstract
This study aims at developing the practical technology in the treatment of box-mill wastewater using the aerobic co-metabolism principle. The conventional activated sludge method exhibited the removal efficiency of $TBOD_5$ and $TCOD_{Mn}$ as 30~50% and 40~50%, respectively. Color was rather increased by 30~130% because the conventional treatment under the aerobic condition did not induce the conversion of molecular structure of dyeing agents. Meanwhile, when the aerobic co-metabolism principle was applied to the same wastewater, the removal efficiency of $TBOD_5$ and $TCOD_{Mn}$ were obtained as 92~97% and 90~94%, respectively. In particular, color was significantly reduced down to 65~85%. The enhancement of treatment efficiency was ascribed to occur not only that the non-degradables were converted to the second substrates, but also that the enzyme activity was increased as MLVSS was kept 3000mg/l or more with the first substrates injected.
