Outline of Final Research Achievements

Treated municipal wastrwater by MBR was reused for the cultivation of microalgae. Microalgae can be use as the source of protein for theaquaculture. The results obtained in the research can be summarized as follows:
1) MBR: Buffled MBR can be operated by controlling the cycle time in bMBR and ORP in the inner part of buffles to maintain the optomum nitrogen oncentration for the microalgae cultivation. Operation nerg of bMBR was reduced to 0.2 kwh/m3 by using the long (3 m) and high density PTFE membrane module, 2)MIcroalgare:P. Ellipoidea was selected which has the optimum growth pH of 3.0. Protein content of about 18% was obtained, which is almost the same as a sardine.

Academic Significance and Societal Importance of the Research Achievements

本研究の成果により、「水・エネルギ-・食料」のNEXUSに、都市下水を膜分離活性汚泥法(MBR)で処理し、処理水により微細藻類を培養するシステムを導入できる可能性が示唆された。今後は、生産した微細藻類の価値とコストの検討が必要である。なまこ、牡蠣の養殖に使用できる可能性は確認できた。鮎が少ない河川では川底に付着藻類が繁茂して景観を損ねる問題が生じている。微細藻類により稚鮎を養殖し、河川放流すればこの問題も解決し、鮎資源の確保による経済効果も見込める。
