报告人简介：
Prof. Angela Yu-Chen Lin is a Full Professor in the Graduate Institute of Environmental Engineering at National Taiwan University (NTU), Taiwan. She received her B.S. degree from California Institute of Technology (Caltech) in 1999, and M.S. and Ph.D. degrees in Environmental Engineering from Stanford University in 2005. She worked at Kennedy/Jenks Consultants in USA for a year before joining NTU faculty in 2006. She is an environmental chemist focusing on the fate and transformation of trace organic compounds in both natural and engineered systems. Her research and teaching interests are in the area of environmental photochemistry, advanced analytical chemistry, innovative water/wastewater treatment technology, natural attenuation, transport and toxicity of contaminants in aqueous systems, water recycling and reuse. Professor Lin has more than eighteen years of research experience on emerging contaminants such as pharmaceuticals and hormones, perfluorinated chemicals, sunscreen/UV filters, emerging disinfection byproducts and microplastics. She has published more than hundred highly cited peer-reviewed professional papers on the above topics. She was the winner of 2014 Elsevier Scopus Young Researcher Award in Environmental Science Field. Following that, she was awarded UPS Visiting Professorship at Stanford University from 2014-2015. The research by Professor Lin and her students has received numerous engineer and scientist recognitions including Ta-You Wu Memorial Award (2013) and Outstanding Research Award (2018), the two most prestigious awards from Minister of Science and Technology of Taiwan.
报告内容简介:
Water scarcity has long been an issue, forcing us to rely increasingly on degraded water sources such as recycled wastewaters for drinking water. Water resources are prone to pollution through natural and anthropogenic contaminations, resulting in death and disease worldwide. A major source of water pollution is the treated, undertreated and untreated wastewaters released from wastewater treatment plants. In Taiwan, sewage treatment plants also release their effluents into neighboring waterways. Therefore, all pollutants not completely removed during the treatment process are released and enter the receiving water bodies. Among these are Emerging Contaminants that have raised significant concerns in the twenty-first century.
Emerging contaminants are groups of newly recognized and not yet fully regulated water contaminants; including compounds such as pharmaceuticals and personal products, hormones, perfluorinated chemicals, drinking water and swimming pool disinfection byproducts, pesticide transformation products as well as nanomaterials, etc. They were prevalent in drinking waters, wastewaters and recycled waters. Photodegradation may be one of the most important elimination process for emerging contaminants in surface water, and it determines the fate of many recalcitrant trace organics. The photochemistry in the water, solid and suspended phases will be discussed as well as the various photosensitization processes. Enhanced photolysis in the presence of free chlorine and in combination with other oxidation processes in the built environments will also be evaluated along with their associated change of toxicity.
