Municipal wastewater treatment technology innovation

水和废水行业b面临的挑战包括基础设施老化、土地限制、能源需求和资金限制。此外，从废水污染物中回收资源和能源是一种强有力的范式转变。只有开发强化处理工艺才能克服上述挑战，强化处理工艺可实现预期的处理目标(例如，去除悬浮固体、碳、氮、磷等)。减少了时间和/或空间和/或具有更少的能量需求。因此，这项研究的重点是城市污水处理的未来，降低能源消耗，回收能源和其他资源(水和营养物质)。技术往往是单独开发和测试的，没有整合到工艺系列中，因此，测试条件既没有反映城市污水在成分、成分负荷和流量方面的动态，也没有对工艺对下游工艺和其他工艺的影响进行充分评估。因此，该项目的主要目标之一是设计一个试点规模的最先进的废水处理厂，位于伦敦的格林威研究设施，具有足够的灵活性，可以很容易地适应工艺修改、仪器仪表和控制，以及用于废水和生物固体处理的广泛的生物、物理化学和热能技术。这一设计的设施将是该地区独一无二的，使大学研究人员能够进入真实世界环境中的试验台，并使行业研究人员能够在工厂范围的环境中评估他们的新技术。尽管由于各种社会经济限制，在工厂范围内进行技术评估并不总是可行的，但建模和模拟是评估新兴技术的可行工具。商业上可用的建模软件在对生物和物理化学处理过程进行建模时不包含流体动力学。这项研究项目将把流体动力学融入到整个工厂的模型中，用于试验工厂。

The challenges facing the water and wastewater industry b include aging infrastructure, land constraints, energy demands, and financial limitations. Furthermore, there is a strong paradigm shift towards resource and energy recovery from wastewater contaminants. The aforementioned challenges could only be overcome by developing intensified treatment processes - processes that achieve the desired treatment objectives (e.g., removal of suspended solids, carbon, nitrogen, phosphorous, etc.) in reduced time and/or space and/or with less energy requirement. Thus, the focus of this research is on the future of municipal wastewater treatment where energy consumption is reduced and energy and other resources (water and nutrients) are recovered. Often technologies are developed and tested alone, without integration in process trains and accordingly, neither do the testing conditions reflect the dynamics of municipal wastewater in terms of composition, constituent loadings, and flows, nor are the impacts of the process on downstream processes and others fully assessed. Thus one of the main objectives of this project is to design a pilot scale state-of-the-art wastewater treatment plant to be situated at the Greenway Research Facility located in London, ON that is flexible enough to readily accommodate process modifications, instrumentation, and control, as well as a broad range of biological, physiochemical, and thermal technologies for both wastewater and biosolids treatment. This designed facility will be one of a kind for this region, enabling university researchers and giving them access to a test bed in a real-world environment and enabling industry researchers to evaluate their new technologies in a plant-wide setting.While technology evaluation in a plant-wide setting is not always feasible due to various socio-economic constraints, modelling and simulation is a viable tool for evaluation of emerging technologies. The commercially available modeling software do not incorporate fluid dynamics in modeling biological and physio-chemical treatment processes. This research project will incorporate fluid dynamics in plant-wide models for the pilot plant.
