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.

造纸工业是世界上用水量最大、污染最严重的工业之一。由此产生的制药废水具有极高浓度的有机污染物和固体。未经充分处理的制药废水排入环境，对生态系统和水生物种产生不利影响。目前，由于制药废水中污染物的复杂性质，没有一种成本有效且节能的单一制药废水处理工艺。本研究旨在开发具有成本效益的制药废水处理策略。具体来说，研究小组将开发强大的综合处理，使用颗粒污泥为基础的生物反应器，以实现能源回收，减少营养物质，并从制药废水中水回用。刘博士的实验室开发的生物化学和分子工具将被应用于推进颗粒污泥中微生物在各种操作条件下的理化和生物学特性和活动的知识。这些活动将使我们能够评估生物降解机制，并为未来的全面，具有成本效益的实施提供指导。
