Outline of Final Research Achievements

Characteristics of biological transformation under high temperature condition with bioreactor for wastewater treatment were investigated. High temperature condition compared with that used in conventional process can promote biological transformation. For example, methane fermentation, lactic acid fermentation are prioritized under the higher temperature condition. Anammox reaction was promoted around 35°C condition. It is confirmed by molecular biological technique that some microbial flora which can make the biological reaction was formed in each desirable condition. Energy and resource recovery can be conducted as results. On the other hand, some higher temperature condition can provoke undesirable adverse reaction such as N2O production. Enhancement the efficiency of desirable condition avoiding undesirable adverse reaction is required, and the fundamental information was collected and organized as the useful knowledge in this study.
