|Outline of Final Research Achievements
Energy-saving and low-cost DHS reactor has an attractive potential to highly retain even poorly-culturable bacteria. This study evaluated the performances of long and continuously operated DHS reactors applied for the following six novel environmental technologies. (1) minor metals recovery by Mn oxidizing bacteria, (2) dissolved methane recovery from anaerobic wastewater treatment effluent, (3) nitrification at low pH, (4) simultaneous decomposition of nitrous oxide and methane of global warming gases, (5) phosphorus recovery from eutrophied pond and river, (6) nitrogen removal by simultaneous nitritation and anammox reaction. The result shows that the treatments and the recoveries are possible.
