| 研究実績の概要 |
During Year 2019, the following works were completed. (1)Algal-bacterial aerobic granular sludge (AGS) system has been confirmed to effectively remove organics and nutrients under no air bubbling condition. (2)Algal-bacterial AGS system can be operated in continuous-flow mode, achieving stable and high-efficacy performance with much less energy consumption. (3)Algal-bacterial AGS biomass can also be used for biodiesel production due to its high lipid accumulation under appropriate operation condition. (4)New algal-bacterial AGS system can be quickly established (<18 days) when inoculation of small amount of mature algal-bacterial AGS into bacterial AGS system is applied. (5)Two isolated microalgae species were identified to contribute to granulation process and nutrients removal.

| 今後の研究の推進方策 |
(1)Comparison will be further conducted between the bacterial aerobic granular sludge (AGS) and algal-bacterial AGS systems, especially on CO2 sequestration, nutrients accumulation and energy consumption.
(2)Major differences between the naturally growing algae- and functional algae-based AGS systems will be investigated, so as to make clear the advantages of algae cultivation and harvesting between algal-bacterial AGS and the commonly used suspension culture/flotation systems.
(3)The potential of algal-bacterial AGS will be explored on heavy metal removal and recovery from wastewater, targeting the establishment of a side-stream dynamic adsorption/desorption unit to the whole algal-bacterial AGS system.
