PI：Kartik Chandran建议编号：CBET-1066860机构：哥伦比亚大学标题：GALI：现场ANAMMOX反应器的设计、启动和控制策略Anammox是一种新型且经济高效的工程生物脱氮(BNR)策略，该策略涉及使用亚硝酸盐作为终端电子受体将氨氧化为氮气。尽管Anammox与传统BNR相比具有明显的优势(更低的运行成本和能源需求，更低的二氧化碳排放量)，但美国第一个全面安装Anammox的项目尚未开始。在NSF的这个目标项目中，PI建议开发基于实验和模型的策略，通过学术研究实验室和行业之间的协同努力，促进美国Anammox反应器的快速启动和长期稳定运行。这项研究提出的关键研究和应用问题是：厌氧氨氧化群落的最佳功能和结构组成是什么，最终通过厌氧氨氧化系统实现稳定的氮去除？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保局和CH2M Hill.这个NSF Goali项目是美国首次系统地全面实施Anammox的尝试之一，也是第二次试点实施Anammox。利用新的分子技术，如群落特征和基因表达，黑匣子？Anammox将会被打开。分析和建模工作将导致更好地理解工程设计的具体机制。稳定的多物种厌氧氨氧化群落。最终，这个项目的成果可以帮助促进Anammox广泛适应BNR，基于对中介这些途径的微生物的机械理解。这个NSF目标项目致力于以环境可持续的方式减少氮污染“，这是美国国家工程院定义的重大工程挑战之一，预计将为纽约市的脱氮计划和美国更多采用Anammox的公用事业公司做出重大贡献。因此，NSF的这一目标项目有望对发展BNR的厌氧氨氧化实践产生强大而广泛的影响。此外，该NSF项目将支持两种以社区为基础的面向学生和教师的外展模式。首先，PI将通过现有的CTICE K-12计划将他的研究整合到纽约州哈莱姆区一所面向少数族裔的学校FDA的高中教育中。在现有教育模式中增加这些新的方面，预计将通过改进中学教育来补充哈莱姆区正在进行的社会和经济复兴。其次，国家科学基金会STEP教师培训计划的高中科学教师参与者将于夏季在皮耶斯？S实验室主持，该计划旨在促进科学教育的课程改进。

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.
