| Research Abstract |
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.
