在过去的几年里，紫外线(UV)辐射已成为最好的净水替代方案之一。紫外光发光二极管(UV-LED)是一种新技术，最近经历了快速的改进和新的可能的应用。这些进展为基于LED的新型净水器的开发创造了机会。事实上，通过取代传统的UV汞灯，UV-LED可能会给水处理系统带来革命性的变化。*在拟议的研究计划中，我们计划探索如何利用UV-LED的某些独特功能来显著改善水的净化。我们将研究用于水处理的UV-LED的基本原理及其在开发新型UV-LED反应器中的应用。我们将进一步研究UV-LED的几个独特特性的影响，这些特性可能会导致更有效的水净化方法。此外，我们将模拟、优化和设计原始的UV-LED反应器，提供对流体和光学环境的精确控制，以实现卓越的反应器性能。最后，我们将制造和操作UV-LED反应器原型，以确定这项新兴水净化技术的能力和局限性，以及它在以前从未使用过UV反应器的应用中的潜力。*首席研究员在工业和学术界开发用于水处理的UV反应器方面拥有超过15年的经验。他在UBC发起并建立了一个强大的研究计划，专注于与工业合作伙伴合作开发用于净水的UV反应器。*我们预计这项研究将导致开发出具有高效率和特殊功能的下一代UV反应器，这些特性是目前紫外灯反应器和其他现有技术所不具备的。在该项目期间培训的学生将具备领导加拿大水和环境行业世界级研究和开发活动的高度资格。加拿大在开发紫外线净水反应堆方面处于世界领先地位，加拿大公司在销售基于紫外线的水处理系统方面发挥着重要作用。因此，我们处于极好的地位，可以开发这项技术并从中受益，并从该领域高素质研究人员的培训中受益。*这项研究计划将新兴技术机会应用于一个重要的社会问题。许多偏远和小型社区对水传播疾病的日益关注推动了对新的水处理系统的需求，以满足他们的特殊需要。拟议的研究计划计划通过开发高效和紧凑的UV-LED反应器来推进基于UV的水净化领域，以满足这一需求。这些反应器将在低功率下运行，并且几乎无需维护。**

Ultraviolet (UV) irradiation has emerged in the past few years as one of the best water purification alternatives. The ultraviolet light emitting diode (UV-LED) is a new technology that has recently experienced rapid improvements and new possible applications. These advances create the opportunity for the development of novel LED-based water purifiers. In fact, UV-LEDs could potentially revolutionize water treatment systems by replacing traditional UV mercury lamps.***In the proposed research program, we plan to discover how certain unique features of UV-LEDs can be utilized to significantly improve water purification. We will study the fundamentals of UV-LEDs for water treatment and their application in the development of novel UV-LED reactors. We will further investigate the impact of several unique characteristics of UV-LEDs, which are likely to result in much more efficient methods of water purification. Furthermore, we will simulate, optimize, and design original UV-LED reactors that offer the precise control of both the fluidic and optical environments to achieve superior reactor performance. Finally, we will fabricate and operate UV-LED reactor prototypes to identify the capabilities and limitations of this emerging technology for water purification as well as its potential for applications where UV reactors have never before been used.***The principal investigator has over fifteen years of experience in the development of UV reactors for water treatment in both the industry and in academia. He has initiated and established a strong research program at UBC that focuses on the development of UV reactors for water purification in collaboration with industrial partners.***We expect this research to result in the development of the next generation of UV reactors with high efficiency and special features that are currently unavailable in UV-lamp reactors and other incumbent technologies. The students trained during this program will be highly qualified to lead world-class research and development activities in the Canadian water and environmental industries. Canada is a world leader in the development of UV water purification reactors, and Canadian companies play a significant role in marketing UV-based water treatment systems. As a result, we are in an excellent position to exploit and benefit from this technology and from the training of highly qualified researchers in this field.***This research program applies an emerging technological opportunity to an important social issue. Growing concern over the waterborne diseases in numerous remote and small communities has driven demand for new water treatment systems to meet their special needs. The proposed research program plans to address this demand by advancing the field of UV-based water purification through the development of efficient and compact UV-LED reactors, which will operate at low power and are practically maintenance-free.**
