Technological development of crushing mass minute creature to micro size pieces by high speed rotating fluid motion and its water treatment system using micro-nano-technology

利用微纳气泡技术，开发了高速旋转流体运动将大量微小生物破碎成微小颗粒的技术及其水处理系统。研究结果如下。(1)高速旋转法产生的微气泡几乎全部收缩为微纳气泡。在这样做的过程中，内部气体在收缩过程中从气泡中喷出。(2)微气泡的负电位随气泡的收缩而增大。特别地，在气泡直径的尺寸从40μm开始减小的情况下，电位显著地急剧增加，并且具有峰值电位的气泡的直径为约10-30μm。(3)微泡在由微泡向微纳泡收缩的过程中自身发光。(4)发现微气泡的供给对生物生理特性的作用。利用气泡的作用，可以防止贝类的灭绝，促进动植物的生长，延缓人体衰老。此外，通过控制微气泡的产生量来进行细菌的清洁和消毒。(5)通过研制微型气泡发生器，使大量微小生物在发生器中高速旋转，产生气液两相流。(6)通过在废水的曝气池中供应微气泡，活性污泥中的细菌数量加倍。

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.
