英文摘要： Coagulation (flocculation) is one of the widely used techniques in water and wastewater treatment, and is important research direction in the field of environmental engineering. In view of the complex and volatile water pollution status, rapid development of science and technology and increasingly rigorous water quality standards, traditional coagulation technology and old water plant processes are facing tough challenges. Therefore, there is an urgent need to strengthen the improvement of coagulation technique and development of new process principles. . The presence of micro-pollutants including disinfection byproducts in drinking water poses a great threat to safe water supply. Focused on the forefront hot issues of complex and dynamic reaction in multi-media and multi-interface systems, the proposed project is aimed at one of the highlighting problems in water quality and safety control, that is, enhanced removal of organic micro-pollutants. The main content of this project includes dynamic real-time monitoring of multiple water quality parameters, efficient multi-functional coagulant species design and coagulation mechanism investigation, and studies on the floc formation and structure regulation at different stages and reaction process strengthening and optimization of dynamic and complex water quality processes. Through in-depth study of interactions occurred within the system consisting with aqua-particles, micro-pollutants, and multi-functional coagulant and water solution, to understand the collaborative optimization of coagulation with other water treatment processes, in order to promote the new enhanced micro-polluted organic flocculation technology process and technical principle establishment as well as the development of the discipline.
