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

这个小企业创新研究（SBIR）第二阶段项目将建立在第一阶段取得的成功成果。第一阶段的研究表明，氯水溶液可用作高级氧化工艺（AOP）的替代化学源，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在发展一个坚实的理解，如何水性氯为基础的高级氧化工艺可以整合到整个水处理工艺，比较效力的水性氯和过氧化氢为基础的高级氧化工艺，并证明太阳紫外线可以用来驱动这一进程。更广泛的影响，这项研究中心的能力，提供一个更绿色，更有效的AOP，可用于更经济地生产高质量的水。第二阶段的研究将提高对氯基AOP技术的理解，从而能够开发出具有增强能力的产品，以去除水中的痕量有机污染物。 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，该研究还可以通过矿化永久性地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，由于这一过程可以利用太阳能驱动，因此所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.
