Report 068


All in all, the object of this research is to keep the balance of aquatic ecological environment, and manage the quantity and quality of aquatic ecological environment through water reuse. Therefore, based on establishing methods of detection analysis and risk evaluation, this research will study the fate of highly risky trace chemical substance and pathogens as the preferential control pollutant in reclaimed water and aquatic environment, and evaluate the eco-toxicity and ecological effect of water reused for ecological environment. And the research will mainly focus on the principle of enhanced integrated removal technologies in order to find way to reduce the risk of reuse water. This project will be conducted through cooperative research between Kyoto University and Tsinghua University.
This project, whose mission is to reduce environmental risk and establish methods for water quality monitoring as well as risk assessment, will be based on the comparison of the existence level and risk assessment of trace chemical substances and pathogens in the aquatic environment of both countries. It is convinced that the research will also provide scientific evidences and technical supports for the safety of wastewater reclamation and harmony in the ecological environment.
We have already held similar symposia within three years, and this symposium is the third one. We have this symposium to the same effect and make the research summation.


Professor Hiroshi TSUNO, the research leader of this project made the opening speech and explained the project summary. Four presentations were made by Japanese and Chinese sides in the morning. Vigorous free discussion was made after presentations. Poster session was held after lunch time and 22 research presentations were conducted. Four presentations made by both Japanese and Chinese sides were followed. Panel discussion was presented with Prof. Xia HUANG, Prof. Sadahiko ITOH, Dr. Naoyuki YAMASHITA by Prof. Hiroshi TSUNO, the chair of the session. Active discussion was performed with participants.
The development of the treatment technology and the effect against the risks were shown though the symposium, and appropriate countermeasures were presented. Monitoring technology developed in this research with the environmental data accumulated by the investigation and its evaluation were also performed. Many graduate students took part in this symposium and some of them made their research. This symposium was also effective for students from the points of education for young researchers.
