Outline of Final Research Achievements

The present study aimed to develop a technology to treat sewage inside sewer pipe based on a principle named intermittent contact oxidation process (ICOP), and to clarify the effect of the condition on microorganisms. When sewage flow is low, water level decreases, and microbial media installed exposed to air. In ICOP, oxygen is supply to microorganisms when microbial media is exposed to air, and the process does not consume electrical power. In the present study, the performance of ICOP was clarified. Areal oxygen supply capacity was estimated to be around 30g/m2/d though it depends on conditions. On the other hand, effects of ICOP conditions on microorganisms remained to be studied in the future.

Academic Significance and Societal Importance of the Research Achievements

近代下水道は下水の収集システムとしての下水道と処理装置としての処理場に明確に区別されている。本研究は、下水道管路の水質浄化機能をたかめ、処理機能の一部を担わせることが可能であることを実験レベルで示した。さらに、本研究の用いる技術は電力を消費しない省エネルギー型技術である。人口密度の高い大都市には向かないが、大都市周辺や人工減少地域に適用できる可能性がある。
