Nitrous Oxide Management in a Novel Biological Process

该研究将集中在减少水和废水处理过程中一氧化二氮的产生，这种温室气体的破坏性比二氧化碳大310倍。合适的博士候选人可能具有生物科学（包括生物化学和微生物学）化学，环境科学或化学工程的背景。本研究的目的是探讨一种新的膜充氧生物法处理污水的示范工厂选址在剑桥的一氧化二氮的形成机制。生物过程从电解槽接收氧气，电解槽从废水中产生氢气：这在下面的图表和https://waterinnovation.challenges.org/winners/triple-carbon-reduction/上的视频中进行了总结。微生物介导的途径在一氧化二氮的产生和衰减中至关重要，这取决于系统中的环境条件。将对示范工厂进行质量和能量平衡，以确定一氧化二氮排放量和缓解措施的效果。 克兰菲尔德大学是一所专注于技术和管理的研究生大学。水主题（www.cranfield.ac.uk/themes/water/about-us）是英国最大的专注于水和废水科学，工程和管理的学术中心。研究人员来自生物化学和物理科学，环境科学和管理，工程学科以及管理和社会科学的背景。博士将有机会获得全面的实验室资源和技术支持的环境分析设施（www.cranfield.ac.uk/facilities/environmental-analytical-facility）。研究结果将通过生产氢气结合高效的废水处理来降低温室气体排放，以保护环境，并为社会提供净零碳排放。该项目提供了一个独特的机会，作为350万英镑OFWAT（水务监管机构）创新基金项目的一部分，该公司开发了尖端的废水处理技术，即膜曝气生物反应器（MABR）的纯氧版本。除了克兰菲尔德的工作人员和同事外，您还将与Anglian Water领导的更广泛的项目团队进行互动，合作伙伴包括Oxyglow，Element Energy Ltd，Jacobs，东安格利亚大学，布鲁内尔大学，塞文特伦特，苏格兰水务，北方爱尔兰水务和联合公用事业。您将被要求在国际水协会（IWA）两年一次的大会等大型国际会议上至少发表一次演讲。作为WIRe CDT（https：//cdtwire.com/）的学生，您也将成为2022年队列的重要成员，其中包括来自纽卡斯尔和谢菲尔德大学的学生。在博士学位结束时，成功的候选人将在学术界，政府和行业中发挥作用。除了能够提供研究，你将获得沟通，数据分析，数字，项目管理和写作，这将是在企业，政府和大学的管理和领导职业无价的可转移技能。

The research will centre on reducing the production of nitrous oxide, the greenhouse gas 310 times more damaging than carbon dioxide on a weight for weight basis, during water and wastewater processing. Suitable candidates for the PhD may have a background in biological sciences (including biochemistry and microbiology) chemistry, environmental sciences or chemical engineering. The aim of the research is to investigate the mechanisms of nitrous oxide formation in a novel membrane oxygenated biological process for wastewater treatment from a demonstration plant sited in Cambridge. The biological process receives oxygen from an electrolyser that is producing hydrogen from wastewater effluent: this is summarised in the diagram below and the video at https://waterinnovation.challenges.org/winners/triple-carbon-reduction/. Microbially mediated pathways are critical in the production and attenuation of nitrous oxide depending on the environmental conditions in a system. Mass and energy balances will be conducted on the demonstration plant to establish nitrous oxide emissions and the effect of mitigation measures. Cranfield University is an exclusively postgraduate university focussed on technology and management. The Water Theme (www.cranfield.ac.uk/themes/water/about-us) is the largest dedicated academic centre focussed on water and wastewater science, engineering and management in the UK. Researchers come from backgrounds in biological chemical and physical sciences, environmental science and management, engineering disciplines as well as management and social sciences. The PhD will have access to the comprehensive laboratory resources and technician support in the Environmental Analytical Facility (www.cranfield.ac.uk/facilities/environmental-analytical-facility).Results of the research will enable lower greenhouse gas emissions through production of hydrogen combined with efficient wastewater treatment to protect the environment and deliver net zero carbon emissions for society.The project offers the unique opportunity to work on a cutting-edge wastewater treatment technology, a pure oxygen version of the Membrane Aerated Bioreactor (MABR), as part of a £3.5 million OFWAT (the water services regulator) Innovation Fund project. As well as staff and colleagues at Cranfield, you will be interacting with the wider project team led by Anglian Water with partners Oxymem, Element Energy Ltd, Jacobs, University of East Anglia, Brunel University, Severn Trent, Scottish Water, Northern Ireland Water and United Utilities. You will be expected to deliver at least one presentation at a major international conference such as the International Water Association (IWA) Biennial Congress. As a student within the WIRe CDT (https://cdtwire.com/) you will also be an essential member of the 2022 cohort that includes students from Newcastle and Sheffield Universities.At the end of the PhD, the successful candidate will have developed skills for roles in academia, government and industry. As well as being able to deliver research, you will have gained transferable skills in communication, data analytics, digital, project management and writing that will be invaluable for management and leadership careers in business, government and universities.
