▶Educational experience

•In 1975, he received a bachelor's degree from Department of water supply, drainage and HVAC engineering, Tongji University

•In 1981, he received a master's degree from the Department of environmental engineering, Tsinghua University

•In 1988, he received a doctorate in civil engineering from Texas State University at Austin

▶work experience

•Elected academician of Chinese Academy of Engineering in 2011

•In October 2013, he was appointed as professor of Tongji University and served as director of the Institute of cleaner production of Tongji University

▶ Academic contribution and part time job

     China's first large-scale cleaner production project in line with international standards was introduced, and China's first unit specialized in cleaner production research was established, which influenced and promoted China's cleaner production process in terms of cognition, technology and method. The first quantitative research project of pollution production coefficient in China was carried out, and a relatively systematic and complete basic data research method of industrial pollution sources in China was constructed. Foam plate tank and high-pressure water gun are respectively the landmark equipment of electrolytic zinc and electrolytic manganese industries since their birth, and they are also the largest source of heavy metal wastewater pollution. The large-scale clean production complete equipment with intelligent manufacturing, automatic control and multi-functional robot technology as the core developed by academician Duan led the team has reduced the production of electrolytic zinc plate washing wastewater by more than 80% and electricity consumption in demonstration enterprises More than 85% of the heavy metal wastewater is produced, and the bubble plate tank and high-pressure water gun which have existed in electrolytic zinc industry for more than 100 years and electrolytic manganese industry for more than 70 years have been successfully cancelled.

•He was vice president of the Chinese Academy of Environmental Sciences

•director of heavy metal cleaner production engineering technology center, Chinese Academy of Environmental Sciences

•Vice chairman of industrial ecological economy and Technology Committee of China Society of Ecological Economics

•Vice president of China industrial energy conservation and Cleaner Production Association
