项目负责人：Kartik chandran提案编号：cbet -1066860机构：哥伦比亚大学标题：目标：现场规模厌氧氨氧化反应器的设计、启动和控制策略厌氧氨氧化是一种新型的、具有成本效益的工程生物脱氮（BNR）策略，它涉及使用亚硝酸盐作为终端电子受体将氨生物氧化为氮气。尽管anammox比传统的BNR有很多优势（更低的运行成本和能源需求，更低的二氧化碳足迹），但在美国，第一个全面安装的anammox尚未开始。在NSF GOALI项目中，PI建议制定基于实验和建模的策略，通过学术研究实验室和工业界的协同努力，促进美国厌氧氨氧化反应器的快速启动和长期稳定运行。本研究提出的关键研究和应用问题是？什么是厌氧氨氧化菌群落的最佳功能和结构组成，最终通过厌氧氨氧化系统实现稳定的脱氮？参与该项目的学术团队来自哥伦比亚大学和丹麦技术大学。行业合作伙伴是纽约市环境保护部和CH2M Hill。这个NSF GOALI项目代表了美国第一次全面系统尝试和第二次中试规模厌氧氨氧化的实施。利用新的分子技术，如群落分析和基因表达，“黑盒”厌氧氨氧化将被打开。分析和建模工作将导致对特定机制的更好理解，从而使“工程”成为可能。稳定的多物种厌氧氨氧化群落。最终，该项目的结果可以帮助促进厌氧氨氧化对BNR的广泛适应，基于对介导这些途径的微生物的机制理解。这个NSF GOALI项目致力于以环境可持续的方式减少含氮污染，这是美国国家工程院定义的重大工程挑战之一，预计将对纽约市的氮去除计划和美国其他采用厌氧氨氧化的公用事业做出重大贡献。因此，该NSF GOALI项目有望对BNR厌氧氨氧化实践的发展产生强大而广泛的影响。此外，这个国家科学基金项目将支持两种基于社区的学生和教师外展模式。首先，PI将通过现有的CTICE K-12项目，将他的研究融入纽约哈莱姆区一所面向少数族裔的学校FDA的高中教育中。将这种新颖的维度添加到现有的教育模式中，有望通过改善中学教育来补充哈莱姆正在进行的社会和经济复兴。第二，参加国家科学基金会STEP教师培训计划的高中科学教师，旨在使科学教育的课程得到加强，将在PI？在美国的实验室工作。

PI: Kartik ChandranProposal Number: CBET-1066860Institution: Columbia UniversityTitle: GOALI: Strategies for Design, Startup and Control of Field-Scale Anammox Reactors Anammox is a novel and cost effective strategy for engineered biological nitrogen removal (BNR), which involves the biological oxidation of ammonia to nitrogen gas using nitrite as the terminal electron acceptor. Despite the well documented advantages of anammox over conventional BNR (lower operating cost and energy requirements, lower CO2 footprint), the first full-scale installation of anammox in the United States has yet to start. In this NSF GOALI project, the PI proposes to develop experimental and modeling based strategies to promote rapid startup and long-term stable operation of anammox reactors in the United States through a concerted collaborative effort between academic research labs and industry. The critical research and application question posed by this study is ?what is the optimal functional and structural composition of anammox communities that ultimately results in stable N-removal via anammox systems?? The academic teams involved in this project are from Columbia University and the Technical University of Denmark. Industry partners are the New York City Department of Environmental Protection and CH2M Hill.This NSF GOALI project represents one of the first systematic attempts at full-scale and the second pilot-scale implementation of anammox in the United States. Using novel molecular techniques such as community profiling and gene expression, the ?black-box? of anammox will be opened. The analytical and modeling effort will lead to a better understanding of the specific mechanisms by which to ?engineer? stable multi-species anammox communities. Ultimately, the results of this project can help to promote widespread adaptation of anammox for BNR, based on a mechanistic understanding of the microbes that mediate these pathways.This NSF GOALI project addresses reducing nitrogenous pollution in an environmentally sustainable fashion", one of the grand engineering challenges defined by the NationalAcademy of Engineering and is expected to contribute significantly to the nitrogen removal program of New York City and additional utilities in the United States that adopt anammox. Therefore, this NSF GOALI project is expected to have a strong and wide impact on developing the practice of anammox for BNR. In addition, this NSF project will support two modes of community based outreach to students and teachers. First, the PI will integrate his research into high school education in FDA, a minority oriented school in Harlem, NY through the existing CTICE K-12 program. Adding such novel dimensions to existing educational models is expected to complement the ongoing social and economic rejuvenation of Harlem by improvements to secondary education. Second, high-school science teacher participants in the NSF STEP Teacher Training Program, aimed at enabling curricular enhancements in science education will be hosted in the PI?s laboratory during the summer.
