This study was performed to evaluate the application of $TiO_2$ on the photocatalytic treatment of swine wastewater. $TiO_2$ sol was prepared by hydrothermal method with the agent ratio($(C_2H_5)_2NH_2\;mol/Ti(OC_3H_7)_4\;mol)=1$ and R ratio ($H_2O\;mol/Ti(OC_3H_7)_4\;mol)=42$. The effect of parameter on the removal efficiency of swine wastewater in a batch type immobilized photocatalyst system such as initial pH, intensity of UV, dosage of $TiO_2$, air flow rate, and concentration of $H_2O_2$ was examined. Wastewater was effectively eliminated in the presence of both UV light illumination and $TiO_2$. Photocatalytic activity was higher in acidic condition compared to neutral and alkaline conditions. In addition, photocatalytic activity increased with increasing UV light intensity, dosage of $TiO_2$, the flow rate of air and the amount of $H_2O_2$ added as an oxidant, but the excess amount of $H_2O_2$ dosage decreased the removal efficiency.
