在液态水中的等离子体产生或等离子体注入为人们提供了将高级氧化过程非热注入水中以用于净化或化学处理的机会。这种技术可能会彻底改变饮用水的处理，以及通过消除物理催化剂来改变目前的化学处理方法。本文概述了目前的水处理技术，其局限性和未来，其中可能包括基于等离子体的高级氧化技术。因此，这一领域代表了一个新兴和活跃的研究领域。等离子体驱动的水化学可以发挥的作用，在解决新出现的威胁，供水讨论使用案例研究的例子。传统等离子体注入方法的局限性包括有限的生产能力、电极侵蚀和减小的工艺体积。在密歇根大学，我们正在研究两种旨在规避此类问题的潜在方法。这些包括使用水下DBD等离子体射流的直接等离子体注入和通过脉冲电场在隔离的水下气泡中直接产生等离子体。这些方法在这里介绍，沿着的结果。
Plasma production or plasma injection in liquid water affords one the opportunity to nonthermally inject advanced oxidation processes into water for the purpose of purification or chemical processing. Such technology could potentially revolutionize the treatment of drinking water, as well as current methods of chemical processing through the elimination of physical catalysts. Presented here is an overview of current water treatment technology, its limitations, and the future, which may feature plasma-based advanced oxidation techniques. As such, this field represents an emerging and active area of research. The role that plasma-driven water chemistry can play in addressing emerging threats to the water supply is discussed using case study examples. Limitations of conventional plasma injection approaches include limited throughput capacity, electrode erosion, and reduced process volume. At the University of Michigan, we are investigating two potential approaches designed to circumvent such issues. These include direct plasma injection using an underwater DBD plasma jet and the direct production of plasmas in isolated underwater bubbles via a pulsed electric field. These approaches are presented here, along with the results.
