The present study aimed to develop novel sewage treatment technologies with improved energy efficiencies by utilizing microbial ecology. Based on the finding 1) activated sludge can remove organic pollutants with less oxygen consumption under overloaded condition, and 2) temporal carbon storage materials accumulated inside microbial cells are stable during sludge thickening but are readily be degraded to methane in anaerobic digester, a new modified activated sludge was proposed. In addition, a new operational strategy to contribute to peak-cut of electrical power demand was proposed. As the basic aspect on activated sludge microbial ecosystems, the release timing of bacteriophages was studied, an attempt to get a clue on the lysed host species was made, and microbial interactions mediated by chemicals was conducted.

本研究旨在利用微生物生态学开发提高能源效率的新型污水处理技术。 基于这一发现：1）活性污泥在超负荷条件下可以以较少的耗氧量去除有机污染物，2）微生物细胞内积累的临时碳储存材料在污泥浓缩过程中是稳定的，但在厌氧消化池（一种新型改良的厌氧消化池）中很容易被降解为甲烷。提出了活性污泥法。 此外，还提出了有助于电力需求调峰的新运营策略。 作为活性污泥微生物生态系统的基本方面，研究了噬菌体的释放时间，试图了解裂解的宿主物种，并进行了化学物质介导的微生物相互作用。
