摘要
Facing the pressure of excessive water consumption, high pollution load and rainstorm waterlogging,linear and centralized urban water system, system 2.0, as well as traditional governance measures gradually exposed characters of water-sensitivity, vulnerability and unsustainability, subsequently resulting in a full-blown crisis of water shortage, water pollution and waterlogging. To systematically relieve such crisis, we established urban water system 3.0, in which decentralized sewerage systems, sponge infrastructures and ecological rivers play critical roles. Through unconventional water resource recycling, whole process control of pollutions and ecological restoration, system 3.0 with integrated management measures, is expected to fit for multiple purposes which involve environmental,ecological, economic and social benefits. With advantages of flexibility, resilience and sustainability, water system 3.0 will show an increasingly powerful vitality in the near future.

Professor Nanqi Ren, a member of the Chinese Academy of Engineering （CAE）, is the vice president of Harbin Institute of Technology and the director of State Key Laboratory of Urban Water Resource and Environment. He received his Ph.D in Harbin University of Civil Engineering and Architecture, and accomplished his postdoctoral training at the Institute of Engineering Mechanics, National Seismological Bureau. He mainly works on the disciplinary fields of environmental biotechnology, environmental ecology, molecular biology and organic wastewater treatment. Professor Ren has obtained remarkable achievements in the areas of bio-hydrogen production and industrial wastewater treatment. He proposed the bio-hydrogen production technology through organic wastewater fermentation by using anaerobic activated sludge as the strain in 1990, and led development of bio- hydrogen production theory. He also established the first demonstra- tion project of bio-hydrogen production. Prof. Ren has become an academic leader of environmental engineering discipline in Harbin Institute of Technology and the leader of Innovative Research Groups of China ＂Urban water quality transformation role and safeguard technology＂. Professor Ren is currently the member of State Council Academic Degrees Committee Discipline Review Group, and serves as the member of the International Water Quality Association （IAWQ） and other international academic groups. He is also the editorial member for a few core joumals in China. Professor Ren is the recipient of dozens of merit awards, including National Technological Innovation Award, National Prize for Progress in Science and Technology as well as the Provincial and Ministerial Level Scientific and Technological Award. Prof. Ren has published over 300 papers in intemational and Chinese core journals, and made many other important contributions in area of expertise including 9 monographs and works, 19 invention patents and 5 utility model patents.Corresponding author E-mail： xiuheng@hit.edu.cn
