碩士 / 嘉南藥理大學 / 環境工程與科學系 / 106 / In the water treatment plant treatment process, because the raw water containing algae has problems such as shortening the filter process and causing the filter to block the water purification process, in order to improve the problem, the study used iron powder (Fe) ferric oxide (Fe2O3). The algae adsorption and calcination are modified with three commercially available iron oxides such as triiron tetroxide (Fe3O4) to compare the algae removal efficiency before and after the modification.
In this study, the absorbance and turbidity were used as the quantification of algae, the coagulation procedure was carried out with different amounts of iron oxide, and the preferred iron oxide was adsorbed and precipitated by algae by the value of the turbidity meter and the spectrophotometer. After comparison, M-Fe3O4 and iron powder were selected in the experiment, among which M-Fe3O4 has 59% algae removal efficiency and Fe algae removal efficiency is 75%. Ultrasonic wave-breaking recovery separates algae from iron oxide. Compared with the algae removal efficiency of fresh iron oxide, it was found that the recovery of Fe in ultrasonic recovery and its turbidity decreased from 61.8% to 49%, and the absorption value from 78% to 48% was lower than that of fresh iron oxide. There is a slight downward trend, but M-Fe3O4 has not been affected by recycling and reuse, but the algae removal efficiency has increased from 59% to 68%.
