| Outline of Final Research Achievements |
This study focused on small-scale wastewater treatment plants with the iron electrolysis for phosphorus removal. On-site survey and laboratory scale experiment were carried out to clarify the phosphorus removal mechanism and to establish the control methods for stable phosphorus removal. The phosphorus removal performance was increased by the Ca addition even when the phosphorus removal was insufficient from the surveys and the experiments. It was suggested that increase of the amount of insolubilized sludge by the Ca addition enhanced the phosphorus removal performance from the results of synchrotron radiation technique. Therefore, analysis of chemical iron state using the synchrotron radiation technology would be effective to evaluate the phosphorus removal performance. In this study, valuable findings were obtained on the improvement and the mechanism of the phosphorus removal by the Ca addition in the iron electrolysis process.
