SBIR Phase II: Investigation of the Use of Chlorine Based Oxidants for Removal of Natural Organic Matter Using Advanced Oxidation Processes

这个小型企业创新研究(SBIR)第二阶段项目将建立在第一阶段取得的成功成果的基础上。第一阶段研究表明，氯水可用作高级氧化工艺(AOPS)的替代化学来源，并且在紫外光照射下能够产生羟基和其他高活性自由基。这些自由基被用来破坏和矿化小有机分子，并影响地表水中天然有机物的结构。第二阶段的研究将集中于扎实地了解基于氯水的AOPS如何整合到整个水处理过程中，比较基于氯水的AOPS和基于过氧化氢的AOPS的效率，并证明可以使用太阳紫外光来驱动这一过程。这项研究的更广泛影响集中在提供更绿色、更高效的AOP的能力，可以用来更经济地生产高质量的水。第二阶段的研究将提高对基于氯的AOP技术的理解，使产品的开发具有更强的去除水中痕量有机污染物的能力。这项研究的成功完成将对饮用水和包装饮料的质量产生积极影响。此外，这项研究还可以通过矿化永久去除环境中的污染物，防止市政和工业废水处理厂的意外排放。最后，由于这一进程可以使用太阳能来推动，由此产生的技术将以负担得起的成本在世界农村和发展中地区部署。

This Small Business Innovation Research (SBIR) Phase II project will build on the successful results obtained during Phase I. Phase I research indicated that aqueous chlorine can be used as an alternative chemical source for Advanced Oxidation Processes (AOPs), and was capable of producing hydroxyl and other highly reactive radicals when illuminated with ultraviolet light. These radicals were harnessed to destroy and mineralize small organic molecules and impact the structure of natural organic matter found in surface water. Phase II research will focus on developing a solid understanding of how aqueous chlorine based AOPs can be integrated into overall water treatment processes, compare the efficacies of aqueous chlorine and hydrogen peroxide based AOPs, and demonstrate that solar ultraviolet light can be used to drive this process.The broader impacts of this research center around the ability to provide a greener, more efficient AOP which can be used to more economically produce high quality water. Phase II research will deliver an increased understanding of chlorine-based AOP technology, enabling the development of products with enhanced capabilities towards the removal of trace organic contaminants from water. Successful completion of this research will positively impact the quality of both drinking water and packaged beverages. In addition, the research could permanently remove contaminants from the environment through mineralization, preventing unintended release from municipal and industrial wastewater plants. Finally, since this process can be driven using solar energy, the resulting technology will be deployable in rural and developing regions of the world at an affordable cost.
