The original high-dissolved oxygen water was dissolved by oxygen for a long time (15-20 hours), which increased the oxygen content in drinking water, and made high-dissolved oxygen water to achieve the purpose of supplementing oxygen through drinking.

Traditional methods such as bubbling, spraying, and mechanical stirring and mixing can no longer meet the demand, which greatly limits the preparation of high dissolved oxygen water. At this stage, with the continuous improvement of technology, the oxygen content of high dissolved oxygen water continues to increase, but the oxygen content is still limited. At the same time, many companies have added an electrodialysis process to the water treatment process to make water into pure water. Studies have shown that the water contains a large number of elements and trace elements necessary for human metabolism. However, due to the effect of electrodialysis, these elements are all Being filtered has an indispensable impact on the normal metabolism of the human body.

结果分析Result analysis
由实施例1～5以及对比例1制得的高溶氧水对比可知，实施例1～5的高溶氧水含氧量高于对比例1制得的高溶氧水，这是因为，本发明对水源还进行了磁化处理，使得水分子微细化，同时，在水源与氧气混合时还采用了强力磁场进行搅拌，使得氧气分子能更加充分且紧密的植入水分子之间。特别地，本发明在水源与氧气混合时还控制了水源温度、罐体真空度、水源通入速度以及搅拌速度。当水源温度、罐体真空度、水源通入速度以及搅拌速度不同时，各高溶氧水的含氧量也会不同。其中，在合理的范围内，水体温度越低、罐体真空度越低、水源通入速度越慢，搅拌速度越快，溶氧量越高。From the comparison of the high dissolved oxygen water prepared in Examples 1 to 5 and Comparative Example 1, the oxygen content of the high dissolved oxygen water in Examples 1 to 5 is higher than that of the high dissolved oxygen water prepared in Comparative Example 1. This is because, In the present invention, the water source is magnetized to make the water molecules finer. At the same time, a strong magnetic field is used for stirring when the water source is mixed with oxygen, so that the oxygen molecules can be more fully and tightly implanted between the water molecules. In particular, the present invention also controls the temperature of the water source, the vacuum degree of the tank, the inlet speed of the water source and the stirring speed when the water source is mixed with oxygen. When the temperature of the water source, the vacuum of the tank, the speed of the water source and the stirring speed are different, the oxygen content of each high dissolved oxygen water will also be different. Among them, within a reasonable range, the lower the water temperature, the lower the vacuum degree of the tank, the slower the water inlet speed, the faster the stirring speed, and the higher the dissolved oxygen content.
根据上述说明书的揭示和教导，本发明所属领域的技术人员还能够对上述实施方式进行变更和修改。因此，本发明并不局限于上述的具体实施方式，凡是本领域技术人员在本发明的基础上所作出的任何显而易见的改进、替换或变型均属于本发明的保护范围。此外，尽管本说明书中使用了一些特定的术语，但这些术语只是为了方便说明，并不对本发明构成任何限制。Based on the disclosure and teaching of the foregoing specification, those skilled in the art to which the present invention belongs can also make changes and modifications to the foregoing embodiments. Therefore, the present invention is not limited to the above-mentioned specific embodiments. Any obvious improvement, replacement or modification made by those skilled in the art on the basis of the present invention shall fall within the protection scope of the present invention.
