    摘要: In this study, the energy consumption and the operation cost of using the H2O2/UV process
    to treat wastewater from the color filter (CF) fabrication were evaluated by the electrical
    energy per order (EEO). The results showed that both decolorization and mineralization followed
    the pseudo-first-order reaction. For the UV power of 13 W, as the H2O2 dose
    increased from 50 to 150 mg/L, EEO reduced from 26.5 to 12.8 kW h m−3 order−1 for total
    organic carbon (TOC) and from 11.3 to 5.7 kW h m−3 order−1 for color. That is, by increasing
    the amount of H2O2, the electrical energy efficiency became better due to faster reaction as
    shown by the larger reaction constant k. Moreover, the electrical energy efficiency was better
    for the removal of color than for the removal of TOC as EEO,TOC > EEO,color. Moreover,
    irrespective of TOC and color removals, the EEO values for both UV intensities of 13 and
    9 W were close to each other, implying that a higher intensity could be applied by saving
    the operation time. Through the obtained EEO, the achievable optimum costs to treat CF
    wastewater for reuse were 0.713 US$/m3 for decolorization and 1.214 US$/m3 for
    mineralization.
