项目摘要

Novel wastewater treatment technologies are needed to address the weaknesses of current techniques, and ensure the sustainability of wastewater treatment in the future. In the context of circular economy, conventional wastewater treatment technologies are no longer adequate because of high energy demand, large sludge production, green-house gas (GHG) emissions, inability to remove emerging pollutants (such as microplastics and antibiotics), and poor cold-temperature performance. On the other hand, wastewater can be a valuable resource if technologies were available to cost-effectively extract the water resources, nutrients, and energy contained in it. In recognition of the challenges and opportunities in wastewater, the City of Regina has been seeking future-ready wastewater management strategies that can bring co-benefits. In this project, we will develop a novel granular sludge-dynamic membrane bioreactor (GS-DMBR) system for wastewater treatment in the Canadian Prairies climate. The removal of representative emerging pollutants (such as microplastics) will be optimized; resource recovery (such as clean water resources) will also be explored. Insights in the governing mechanisms will be established by using numerical and statistical tools. The system configuration and operating scheme will be improved based on the wastewater quality and seasonality variations. We think the novel GS-DMBR technology will consume less energy, produce less sludge, emit less GHGs, and remove emerging pollutants more effectively in the Canadian context. The outcomes will not only benefit the partners, the City of Regina and QuantWave Technologies Inc., but also shed light onto sustainable wastewater management in Canada and internationally.
需要新的废水处理技术来解决现有技术的弱点,并确保未来废水处理的可持续性。在循环经济的背景下,传统的废水处理技术不再适用,因为能源需求高,污泥产量大,温室气体(GHG)排放量大,无法去除新兴污染物(如微塑料和抗生素),以及低温性能差。另一方面,如果能够利用技术以经济高效的方式提取其中所含的水资源、营养物质和能量,废水也可以成为一种宝贵的资源。里贾纳市认识到废水中的挑战和机遇,一直在寻求能够带来共同利益的面向未来的废水管理战略。在这个项目中,我们将开发一种新的颗粒污泥动态膜生物反应器(GS-DMBR)系统的污水处理在加拿大草原气候。将优化具有代表性的新兴污染物(如微塑料)的去除;还将探索资源回收(如清洁水资源)。将通过使用数字和统计工具来深入了解管理机制。根据污水水质和季节性变化,对系统配置和运行方案进行改进。我们认为新的GS-DMBR技术将消耗更少的能源,产生更少的污泥,排放更少的温室气体,并在加拿大的背景下更有效地消除新出现的污染物。结果不仅有利于合作伙伴,里贾纳市和QuantWave技术公司,也为加拿大和国际上的可持续废水管理提供了启示。
