| Abstract |
Dye wastewater generally contains strong color and non-biodegradable materials. Therefore, the conventional wastewater treatment plant can hardly meet the regulation of wastewater effluent water. In this study, a pilot plant of the conventional process followed by advanced oxidation process (AOP), was set up to treat the dying wastewater. The treatment efficiencies on the various candidate processes, such as ozone alone, UV alone, ozone/UV, ozone/H₂O₂, H₂O₂/UV and ozone/UV/H₂O₂, were investigated in the various ozone and H₂O₂ doses. As the results, the ozone/H₂O₂ process, among the tested processes, showed the highest efficiency for removing color and COD_(Cr). For color removal, the ozone alone process was enough without combining UV or H₂O₂. No significantly enhanced efficiency for removing color and COD_(Cr) by UV irradiation was observed because of the very low transmittance of UV light in dye wastewater. |
