Abstract
This paper was studied about the characteristics of treatment by ionized gas for livestock wastewater, aiming at the effects of ionized gas on organic matter, hydrophobic and hydrophilic organic matter in livestock wastewater when the new process of advanced oxidation process was applied for meeting the improved the quality of effluent. The organic matter within treated livestock wastewater by ionized gas was partially mineralized according to the time increasement. The $TCOD_{Mn}$ in the livestock wastewater was decreased from 840mg/L to 340mg/L when treated by ionized gas by the enhancement of time. We occupied the equations of $TCOD_{Cr}$, $SCOD_{Cr}$, $TCOD_{Mn}$ and $SCOD_{Mn}$ as to ionized gas treated time. As $TCOD_{Mn}$ increasing ionized gas treated time, the concentration did not meet the water quality, $COD_{Mn}$ 4Omg/L. So, for removing of the remaining organic matter in the efflent after ionized gas, following process is necessary. After treating the livestock wastewater by ionized gas, coagulation was considerable for organic matter removal up to regulation water quality. From UV scans of the treated livestock wastewater by ionized gas, the wastewater has low aromaticity and good colour.
