A study on the revival of water environment using raicro-nano bubble technology

研究了微气泡技术对海洋环境的水净化和海洋生物的复苏。实验结果如下：(1)研制了微气泡产生装置，测量了微气泡直径和上升速度。进一步探讨了微泡收缩的物理机制。(2)采用高速摄像机拍摄微气泡的生成过程。结果表明，微气泡是在大约400转/秒的转速下产生的。研究了微气泡的物理化学特性，并将其称为对微气泡尺寸的影响。(3)发现了微气泡对海洋生物和人体的生理活性特点。提供微气泡的生物皮肤表面的血流量比通常的流量提高了两倍。(4)系统讨论了微泡技术在牡蛎、扇贝和珍珠养殖中的应用效果。在此基础上，阐述了利用微气泡再生水环境技术的可能性。

Water purification of the ocean environment and the revival of the ocean creature by using micro bubble technology were investigated. The results of the experiments are as the following.(1)The generating devices of micro bubble were developed, and the diameter of the bubbles and rising velocity were measured. Further, it was examined about the physical mechanism of a micro-bubble to shrink.(2)The process of generation of micro bubble was taken by high-speed camera. It was cleared that micro bubbles generated at a rotating velocity of about a 400 rps. The physical and chemical characteristics of the micro bubble were examined and the characteristics was called the effect on size of the micro bubble.(3)The characteristic on physiological activity of micro bubble for ocean creature and human body was found. The blood flow on the surface of skin of the creature with providing micro bubbles was promoted two times higher than the usual flow.(4)The results of micro bubble technology for oyster culture, scallop culture and pearl culture were discussed systematically. Based on the above, the possibility of the water environment revival technology by using micro bubble was explained.
