Preparation of photocatalyst TiO2 from Ti-salt flocculated sludge in wastewater treatment and its application |
| 초록 |
Titanium tetrachloride (TiCl4) has recently been investigated as alternative coagulant for the removal of pollutants from wastewater. The removal ratio of organic compounds in wastewater was comparable to the commonly used Al- and Fe-salt coagulants while the settling of sludge was faster, which made the subsequent separation process easier. Flocculation efficiency of the Ti-salt was superior to those of Al- and Fe-salts with an additional benefit that TiO2 could be produced by calcinating the settled floc. The produced titania showed high photocatalytic activity for the removal of volatile organic compounds. A pilot scale plant study was conducted to demonstrate the feasibility of the novel process using TiCl4 flocculation with dye wastewater. A commercially available full-scale plant has been successfully operated with dye wastewater in a dyeing industrial center. |
