15、高浓度溶解氧有什么益处？
答：这一点在就地生物修复过程中是最典型的。生物修复过程受到溶解氧量的制约，得到的溶解氧越多，生物清除速度越快。
Q. What is the benefit of high dissolved oxygen?
A. In situ bioremediation is typically limited by the amount of available oxygen. The more oxygen available, the faster the cleanup.
16、为什么高的溶解氧浓度比空气喷射或ORC 更好？
答：除了向含水层提供更多的氧量外，Super-Ox生产的高浓度溶解氧能够在水中停留的有效时间越长，微生物作用时间越长。
Q. Why are high dissolved oxygen levels better than air sparging or ORC?
A. In addition to the higher mass of oxygen delivered to the aquifer, the high dissolved oxygen concentrations produced by the Super-Ox™ result in significantly longer travel times in an aquifer.
17、为什么用氧气注射水中溶解氧达不到40ppm？
答：因为注射过程是无法控制的，氧的溶解还取决于水的性能。因此，将氧气注射到水中，本质上是效率很低的，很难达到40ppm的氧的饱和浓度。而且将氧输入地下水的量是很少的。
Q. Why can’t I achieve 40 ppm D.O. using oxygen sparging?
A. The sparging process is uncontrolled and is dependent on the aquifer characteristics, making it inherently inefficient. Therefore, it is difficult to achieve oxygen saturation of 40 ppm, and the mass of oxygen transferred into the groundwater (flux) is very low.
18、什么是超级溶解氧设备（Super-Ox）？
答：超级溶解氧设备Super-Ox，是一种生物产品和溶解氧供给的自动系统。超级溶解氧设备简化了完成生物修复的工艺，向生物修复设计者提供简便的规范和安装。
Q. What is the Super-Ox™?
A. Super-Ox™ is an automated biological product application and oxygen delivery system. The Super-Ox™ equipment simplifies the process of implementing in situ bioremediation and provides for easy specification and installation by the remediation system designer.
19、Super-Ox™超级溶解氧设备能产生多高的溶解氧浓度？
答：Super-Ox™设备能产生40ppm以上溶解氧浓度，是空气注入式溶解氧的4倍以上。
Q. How much oxygen does Super-Ox™ equipment generate?
A. The Super-Ox™ equipment generates dissolved oxygen concentrations greater than 40 parts per million, which is more than 4 times the D.O. level achieved by air injection.
