Municipal wastewater treatment technology innovation

水和废水处理行业B面临的挑战包括基础设施老化、土地限制、能源需求和财务限制。 此外，从废水污染物中回收资源和能源的模式也发生了重大转变。 上述挑战只能通过开发强化处理工艺来克服，强化处理工艺是实现所需处理目标的工艺（例如，去除悬浮固体、碳、氮、磷等）以减少的时间和/或空间和/或较少的能量需求。因此，本研究的重点是城市污水处理的未来，其中能源消耗减少，能源和其他资源（水和营养物质）的回收。 技术往往是单独开发和测试的，没有集成到工艺流程中，因此，测试条件既不能反映城市废水在成分、成分负荷和流量方面的动态，也不能充分评估工艺对下游工艺和其他工艺的影响。因此，本项目的主要目标之一是设计一个位于伦敦的绿道研究机构的中试规模的最先进的废水处理厂，该废水处理厂足够灵活，可以随时适应工艺修改、仪器仪表和控制，以及广泛的生物、物理化学和热技术，用于废水和生物固体处理。该设计的设施将是该地区独一无二的，使大学研究人员能够在真实环境中使用测试台，并使行业研究人员能够在工厂范围内评估其新技术。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。 商业上可获得的建模软件在建模生物和物理化学处理过程中不包括流体动力学。 该研究项目将把流体动力学纳入试验工厂的全厂模型中。********

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. ********
