Abstract ▼ AI-Helper

In this study, TFS was manufactured using sewage sludge generated by applying TiCl4 to a total phosphorus treatment facility. Physical and chemical characteristics of TFS were analyzed to determine whether the manufactured TFS was successfully manufactured as TiO2 photocatalyst. As a result of operating, the total phosphorus treatment facility by applying TiCl4 as a flocculent, the total phosphorus concentration in the sewage was reduced from 0.3 mg/l to 0.03 mg/l, recording a over 90% total phosphorus reduction efficiency. In the physical analysis, the crystal structure of the TFS observed an anatase crystal structure. The element composition ratio of TFS is 84.05%, so it is determined that TFS can be used in place of TiO2. The average particle size of TFS is 12.5 ㎛ and the BET is 40.8 m2/g, which is not significantly different from the existing TiO2, P-25. In the NO reduction experiment, which is the cause of fine dust, conducted to determine TFS photocatalytic ability, there is no significant difference in NO reduction efficiency from the existing widely used TiO2, P-25. Therefore, TFS can reduce the amount of carbon dioxide generated by making sludge generated in total phosphorus treatment facilities eco-friendly resources, which can contribute to realizing carbon neutrality. In addition, TFS is considered an eco-friendly material that is excellent economically and environmentally because it can efficiently reduce NO, which is the cause of fine dust.
