The distilleries industry is among the most water-intensive and polluting industries in the world. The resulting distillery wastewater has an extremely high concentration of organic contaminants and solids. Discharge of insufficiently treated distillery wastewater into the environment has a negative impact on ecosystems and aquatic species. Currently, there is no single distillery wastewater treatment process that is cost-effective and energy-efficient, due to the complex nature of contaminants in distillery wastewater. This study aims to develop cost-effective treatment strategies for distillery wastewater. Specifically, the research team will develop robust integrated treatment using granular sludge-based bioreactors to achieve energy recovery, nutrients reduction, and water reuse from distillery wastewater. The biochemical and molecular tools developed in Dr. Liu's laboratories will be applied to advance the knowledge of the physicochemical and biological properties and activities of the microorganisms in granular sludge under various operation conditions. These activities will enable us to evaluate biodegradation mechanisms and provide guidance for future full-scale, cost-effective implementation.

酿酒业是世界上耗水量最大、污染最严重的行业之一。产生的酿酒废水含有极高浓度的有机污染物和固体。未经充分处理的酿酒废水排放到环境中会对生态系统和水生物种产生负面影响。由于酿酒废水中污染物的复杂性，目前还没有一种既经济又节能的酿酒废水处理工艺。本研究旨在制定具有成本效益的酿酒废水处理策略。具体来说，研究团队将使用基于颗粒污泥的生物反应器开发强大的综合处理技术，以实现酿酒废水的能量回收、营养物减少和水回用。刘博士实验室开发的生化和分子工具将用于增进对各种操作条件下颗粒污泥中微生物的理化和生物特性以及活性的了解。这些活动将使我们能够评估生物降解机制，并为未来全面、具有成本效益的实施提供指导。
