Japan-China Collaborative Research Projects

Project Title Japanese
Position and Institution Abstract of Research Project
1 “Innovative wastewater treatment technology coupling with efficient energy recovery based on integrated membrane system” Katsuki KIMURA Associate Professor, Division of Environmental Engineering, Hokkaido University Anaerobic membrane bioreactor (AnMBR) is a promising technology that may enable us to recover a huge amount of energy from municipal wastewater. In this joint project, by addressing the problems associated with membrane fouling in AnMBRs, an innovative municipal wastewater treatment system will collaboratively be developed. Novel anti-fouling membranes and innovative operational strategies will be investigated based on detailed information on foulant characteristics (analyzed by the Japanese laboratory) and microbial population in AnMBRs (analyzed by the Chinese laboratory).

3 “High throughput identification technologies of toxic chemicals for protecting the safety of drinking water” Tsuyoshi NAKANISHI Associate Professor, Department of Pharmaceutical, Gifu Pharmaceutical University This study aims at protecting drinking water quality in major cities in Japan and China. Chinese team will broadly extract water samples in China and Japan, and develop non-target screen technologies based on chemical derivatization combined with high-resolution mass spectrometry. The Japanese team will develop in vivo toxicity evaluation methods with imaging technologies, which will help toxicity assessment for the identified active toxicants. Eventually, the both technologies will be integrated and the both team will try to evaluate the safety of drinking water in Japan and China using the new integrated technologies.

4 “Research demonstration on clean treatment of urban food wastes for biogas production using advanced fermentation and new upgrading technology” Yu-You LI Professor, Department of Civil and Environmental Engineering, Tohoku University The objective of this research is to develop a new system for biogas production from urban food waste by combining advanced fermentation technology and advanced biogas purification technology. Japan side will develop a temperature-phased two-stage fermentation system by design and control of the microbial community. China side will develop an efficient and cheap amine-based composite absorbent to remove CO2 from biogas and upgrade biogas as transport gas fuel, which will have a 10% lower regeneration energy consumption than the traditional ethanolamine adsorbent. The performance of the new integrated system will be evaluated by the construction and operation of a demonstration plant in China.
