Globally and in Canada, municipal and industrial wastewater treatment plants have evolved over decades around conventional design concepts, which emphasize the reduction of organic carbon, suspended solids, nutrients (nitrogen and phosphorus) and pathogens. As a result, these end of pipe processes only reduce environmental consequences of treated wastewater discharges to receiving waters, and are energy intensive and costly to operate and maintain. Dr. Yang Liu's research strives to develop future water services that are more economic, health-protective, and environmentally friendly, allowing ecosystems to restore and supporting the circular economy.A fundamental feature of this innovation comes from treating wastewater as a resource, as there is considerable value in recovered energy, nutrients as well as water for reuse that also provides greater resilience to climate and demographic changes. Key opportunities exist to dramatically improve wastewater resource recovery efficiency through improved understanding of how microbiomes adapt to their engineered environments and developing controllable links between microbial community metabolic profiles and resilience.Dr. Liu's research team is working to address these opportunities, focusing on addressing issues associated with the efficiency and scalability of existing resource-recovery based wastewater treatment technologies through a quantum step change in understanding how biological treatment microbiomes can be adapted for robust high performance. This program will adopt novel omics and machine learning tools, link functional microbial groups with engineering parameters, and develop resource-recovery based treatment from novel source-diverted blackwater and greywater systems, as well as municipal wastewater collected in conventional sewers.Key outcomes from Dr. Liu's research will include improving bioreactor design and operation to reduce overall footprint, enhancing process resilience, and better integrating knowledge to ultimately improve operations and controls, which will address current economic limitations for resource-recovery processes and strive for net-zero goals within both centralized and decentralized community systems. Significant advances for Canadian communities are expected by reducing carbon emissions, improving resource recovery efficiency and process stability, reducing microbial risks at critical control points, and protecting source water quality for future generations.

在全球和加拿大，市政和工业废水处理厂几十年来一直围绕传统的设计理念发展，强调减少有机碳、悬浮固体、营养物质（氮和磷）和病原体。结果，这些管道末端工艺仅减少了经处理的废水排放到接收沃茨的环境后果，并且是能量密集型的并且操作和维护成本高。Yang Liu博士的研究致力于开发更经济、更健康、更环保的未来水服务，使生态系统得以恢复并支持循环经济。这项创新的一个基本特征是将废水作为一种资源处理，因为回收的能源、营养物质和水具有相当大的价值，可重复使用，还能提高对气候和人口变化的适应能力。通过更好地了解微生物组如何适应其工程环境以及开发微生物群落代谢谱和弹性之间的可控联系，存在着大幅提高废水资源回收效率的关键机会。刘博士的研究团队正在努力解决这些机会，专注于解决与现有资源的效率和可扩展性相关的问题，通过了解生物处理微生物组如何适应强大的高性能的量子阶跃变化，基于回收的废水处理技术。该项目将采用新的组学和机器学习工具，将功能微生物组与工程参数联系起来，并开发基于资源回收的新型源头转移黑水和灰水系统处理，以及传统下水道收集的城市污水处理。刘博士的主要研究成果将包括改进生物反应器设计和操作，以减少整体足迹，增强过程弹性，更好地整合知识，最终改善业务和控制，这将解决资源回收过程目前的经济限制，并在集中和分散的社区系统内努力实现净零目标。预计加拿大社区将通过减少碳排放、提高资源回收效率和工艺稳定性、减少关键控制点的微生物风险以及为子孙后代保护水源水质来取得重大进展。
