The water purification in natural waters including the bottom sludge and the revival of the water environment for the water student creature by using the micro-bubble technology ware investigated. The main results are as follows.First, air micro-bubbles and pure oxygen micro-bubbles were supplied to the lower layer made oxygen-less waters in the comparatively shallow dam lake, and the water quality was improved. A change in the water quality due to the diffusion of the micro-bubble was observed around the device establishment point in the range of about an up-down flow way 100 m.Second, micro-bubble technology was applied to scallop culture at Hunka Bay in Hokkaido, and shortening of the culture period, the improvement of the culture working environment and the taste were realized. And the effect on scallop blood flow promotion by the micro-bubble was made clear.Third, micro-bubble technology was applied to the pearl culture in Ago Bay, and the growth promotion of pearl shells and prevention of the death of the shells were realized.On the base of these results, the physical and chemical characteristics of micro-nano bubbles were investigated and the physiological activity of two sheet shells to provide the bubbles was found.

研究了利用微泡技术对包括底泥在内的自然沃茨水体的净化以及水生生物水环境的恢复。主要研究结果如下：第一，空气微泡和纯氧微泡在较浅的堰塞湖中向下层缺氧沃茨提供氧气，改善水质。由于微气泡的扩散，在水质的变化，观察到周围的装置建立点的范围内约100米的上下流动的方式。第二，微气泡技术应用于扇贝养殖在北海道的洪加湾，并缩短了养殖周期，提高了养殖工作环境和口味。第三，将微气泡技术应用于阿戈湾珍珠养殖中，实现了对珍珠贝壳的促生长和防止贝壳死亡，在此基础上，研究了微气泡技术在珍珠养殖中的应用效果。微生物的理化特性研究了纳米气泡，并发现了提供气泡的两个片壳的生理活性。
