Drinking water safety is an important factor that influences economic development, social stability and human health. It is a significant research field in the national intermediate and long term technology development plan. It is also a national and global challenge we are facing.  Division of Drinking Water Safety (DDWS) was set up to resolve the key technology problems in drinking water safety field and promote scientific research, technology improvement and implementation.

As a main investigator, DDWS has undertaken about 20 national key projects, including the National High-Tech Research and Development Program of China (863), the National Key Technologies Research and Development Program of China, the Key Specific Research Project, the National Natural Science Foundation of China, International Cooperation and Provincial Projects in recent years. It has achieved significant progress in the research of technologies for drinking water treatment, and contributed to the promulgation of relevant standards and protocols. It has published more than 200 peer-reviewed papers, edited more than 12 books and handbooks, applied 10 national invention patents and 1 software patent. DDWS also has obtained 8 National and Provincial Awards for research achievement, 1 National Teaching Achievement Gold Medal, 1 National Teaching Achievement Silver Medal, 3 Beijing Education and Teaching Achievement Gold Medal, 3 Beijing Excellent Teacher Awards, 1 National Construction Technology Improvement Award, 1 Tsinghua University ‘Good Teacher and Friend’ Award, 1 National Excellent PhD Award, 1 New Century Excellent Person Support Plan Award, etc.
