微細気泡による大深度への酸素供給模擬実験(G05-7 気泡・粒子・液滴等(1),G05 流体工学部門一般講演)

It is widely known that one of the reasons of pollution of lakes and dams is due to the oxygen shortage in deep part of them. It is very important to improve the quality of water. When we supplied oxygen by sending air bubbles, the effect was not so good by the conventional method such as sending compressed air to deep part of them through a diffuser. Now, we suggest supplying oxygen by sending microbubbles. In this study, we researched distribution of bubbles generated by a microbubble generator and dissolved oxygen changing at each depth.
