利用微纳米气泡技术开发了高速旋转流体运动将大量微小生物粉碎成微米级颗粒的技术及其水处理系统。研究结果如下：(1)高速旋转法转化产生的微气泡几乎全部收缩成微纳气泡。在此过程中，内部气体在收缩过程中从气泡中排出。(2)微泡的负电位随着气泡的收缩而增大。特别是，当气泡直径从40μm减小到10-30μm时，电势急剧增大。(3)微泡在从微泡向微纳气泡收缩的过程中自身产生发光。(4)微泡的供给对生物的生理特性起到了作用。通过气泡的作用，可以防止贝类的灭绝、动植物的生长和人类的延缓衰老。此外，通过控制微泡产生量来进行细菌的清洗和消毒。(5)通过开发微泡发生器，粉碎质量微小的生物，使其在发生器内高速旋转气液两相。(6)通过在废水曝气池中供应微泡，活性污泥中的细菌数量增加了一倍。

The technology of crushing mass minute creature to micro size pieces by high speed rotating fluid motion and its water treatment system were developed using micro-nano bubble-technology. The results of the study are as follows.(1) Almost all micro bubbles generated by high speed rotating method transform were contracted into micro-nano bubbles. In doing so, the internal gas was ejected from the bubbles in the process of the contraction.(2) Negative electric potential of micro bubbles increases with the contraction of the bubbles. In particular, the potential marked a sharp increase in the case of becoming reduced in the size of the bubble diameter from 40μm and the diameter of the bubbles having the peak potential was about 10-30μm.(3) The micro bubbles produced luminescence themselves in the process of the contraction from micro bubbles to micro-nano bubbles.(4) The action of physiological characteristic of biological beings by the supply of micro bubbles was found out. By the effect of the bubbles, the prevention of the extinction of shellfish, the growth of animals and plants and antiaging of human being were worked out. Further, The cleaning and disinfect of bacteria were carried out by the control of the generating amount of micro bubbles.(5) By the development of micro bubble generators, the mass minute creature were crushed to rotate air-liquid fluid in the generator at high-speed rotating.(6) By the supply of micro bubbles in a aeration tank of waste water, the number of bug in an activated sludge doubled.
