Paper Title:
Preparation of Activated Carbon Supported Nano-TiO2 Photocatalyst Material and its Application in Papermaking Midcourse Wastewater
  Abstract

Activated carbon supported nano-TiO2 photocatalyst material was prepared with activated carbon as the carrier and carboxyl methyl cellulose (CMC) as the binder. The results indicated that the optimal TiO2 loading percentage could reach 11.46% when the mass concentration of binder in the dipping solution was 15 g/L. Meanwhile, the optimal experimental results showed that the removal percentage of CODCr from papermaking midcourse wastewater could reach 71.43% under the conditions of 10 W of radiation intensity, 240 minutes of radiation time, 15 g/L of photocatalyst dosage, 4.0 of wastewater pH and 3 mL/L of H2O2 dosage. And the effluent was able to reach China national discharge standard Ⅰ. Furthermore, after three times of repeated use, the activated carbon supported nano-TiO2 photocatalyst material still had a relatively high catalytic activity and stability, and the recycle percentage of the photocatalyst could reach 92.80%.
