Graduate SchoolGraduate School of Integrated Arts and SciencesKazuki Tanaka, a second-year student in the Department of Agricultural Sciences, delivered a presentation titled “Annual Variability in Biological Phosphorus Removal in a Full-Scale, High-Load, Two-Point DO-Controlled OD Process” during the oral presentation session at the 48th Sewerage Research Conference and received the Excellence Award.
The Sewerage Research Conference, held annually since Showa 39, is the largest research conference in the sewerage field. Of the 301 oral presentations this year, only eight were selected for the Grand Prize and Excellence Awards.
Among the eight selected presentations—five of which were presented by working professionals—it is a tremendous honor that Kazuki Tanaka, a student at our university Graduate School, was selected for the Excellence Award.
(Presentation Content)
As part of demonstration tests for the “High-Load Two-Point DO-Controlled OD Method”—an energy-efficient wastewater treatment technology developed through a joint industry-government-academia research project involving Kochi University, Kochi Prefecture, Konan City, Maezawa Industries, and the Japan Sewage Works Agency—we investigated the annual variation in biological phosphorus removal performance at the Noichi Wastewater Treatment Center in Konan City.
The results demonstrated that the newly developed technology exhibits stable and high phosphorus removal performance throughout the year, and showed that the activity of microorganisms involved in phosphorus removal declines during the summer and recovers from fall through winter. Furthermore, the factors contributing to this phenomenon were examined from the perspectives of microbial competition and inflow load.
