Tsinghua University Water Pollution Warning Tracing Source Wins Gold Medal at Geneva International Invention Exhibition

[China Instrument Network Instrument R&D] On April 2nd, the five-day 45th Geneva International Invention Fair was concluded at the Palexpo Convention and Exhibition Center in Geneva, Switzerland. The water pollution early warning tracer developed by Tsinghua University attracted extensive attention during the exhibition and was unanimously endorsed by the panel of experts and visitors. It was awarded the gold medal for the jury of the International Fair.


The water pollution warning tracer was jointly developed by the Wu Jing team of the School of Environmental Studies and the Liu Yongjin team of the Department of Computer Science and Technology. In response to major national needs for early detection of pollution and rapid identification of pollution sources in important environmental regulatory businesses such as drinking water safety, pollution source supervision, and water pollution accident response, the research team has accumulated 14 years of experience in the development of classic fingerprint comparison techniques. Water pollution early warning tracer with independent intellectual property rights.

The instrument has the functions of real-time pollution alarming, quick traceability of pollution emission sources, and contamination retention. It has high recognition accuracy, complete automation of sampling, measurement, cleaning, early warning and traceability, and it takes only 21 minutes to complete an early warning trace. The instrument can promote the long-term improvement of the water environment, and can also promote the control of the source of pollution, so that the environmental input can do more with less. At present, the instrument has been industrialized and used for drinking water safety protection, cross-boundary section pollution warning, pollution source supervision, urban water safety and pollution treatment diagnosis. The instrument was listed in the National Special Instruments Guide for 2017.

The annual Swiss International Exhibition of Inventions in Geneva was founded in 1973. It is a large-scale international exhibition organized by the Swiss Federal Government, the Government of Geneva, the City of Geneva and the World Intellectual Property Organization. It is also the world’s longest-running, largest-scale, international The most influential invention exhibition. The awards of the Expo were in turn divided into the jury's special recognition gold medal, gold medal, silver medal and bronze medal.
