| Outline of Final Research Achievements |
Excess discharge of untreated- organic matter causes a huge accumulation of sediment in water bodies, deteriorating both water quality and ecosystem. To solve these issues, alkaline granular-having fly ash, steel making slag, and bamboo power as main components was developed. In the development, activated conditions of lactobacillus, dissolution of ash components, changes in bacteria activation after supplying ash, and structure of silicic acids that are useful for diatom were elucidated. Furthermore, methods for promoting dissolution of alkaline granular were also proposed. It was observed that benthos inhabitation was improved (uninhabitable to seasonal inhabitable) after the scattering alkaline granular on bottom sediment.
