Prior to coming to China, Josh worked for 10 years in drinking water purification at the Nepal Academy of Sciences, and also participated in water treatment projects and related education activities in rural areas. "Nepal is rich in water resources, but some plains have problems with arsenic (commonly known as arsenic). Water treatment technology is very important," she said.

A mysterious kidney disease has been latent in Sri Lanka since the 1990s, killing 20,000 people for more than 20 years. There are still more than 40,000 patients afflicted with the disease in the country, and about 1,000 die each year from the kidney disease.

"To solve the problem of people's livelihood, we need to provide solutions and technical ideas, and we need to work with different disciplines and enterprises to do these tasks." Wei Yuanxian said. In this regard, they newly summarized a new model of "talent cultivation + scientific and technological cooperation + enterprise follow-up". "The ultimate goal is twofold: to benefit the local people and to cultivate a group of high-level scientific and technological talents friendly to China; and at the same time to enable China's water technology to go global."

In the eyes of those familiar with Tista Joshi, the Nepalese female doctor worked "just like a lunatic" and soaked in the lab all day long. "Recently, I just came to Tongliao, Inner Mongolia to learn practical technologies for drinking water treatment, especially large-scale arsenic treatment. This technology was invented by my research team," Qiao Xi told the China Science Daily.

He believes that high-end talents are the driving force behind the in-depth exchanges between China and developing countries. "By setting up a high-level communication platform and providing training to trainees, we can also learn more about the basic situation of various developing countries and further cooperate."

"Sri Lanka's water treatment facilities are not complete enough, and experts and technicians are relatively lacking." Qure said that the Chinese government funding is now helping us to build some infrastructure, such as building a kidney disease in Polonnaruwa, where the kidney disease is most serious. Hospital, aided by China-Sri Lanka Water Technology Research and Demonstration Joint Center in Kangdi, the holy city. The Chinese Academy of Sciences and relevant departments in Sri Lanka also plan to establish related electrodialysis devices, nanofiltration devices and other technology demonstration projects in the country. "After returning to China, I hope to continue to cooperate with Chinese mentors and scientists to alleviate the kidney problems that have long plagued the people of the motherland," he added.

Harvest is not only academic

In fact, cooperation with Sri Lanka is just one case of cooperation. As part of the international scientific and technological cooperation along the “Belt and Road” of the Chinese Academy of Sciences, CEWE is one of the 5 centers of excellence established by the Chinese Academy of Sciences when it launches the “Development and Cooperation Project for Science and Education in Developing Countries” in 2019. The center is established on the basis of the Chinese Academy of Sciences' Ecological Environment Research Center (RCEES / CAS). Since its establishment three years ago, it has aimed at water and sanitation issues facing developing countries in common, and cultivated talents, technical training, and technical cooperation with dozens of developing countries. The state has launched exchanges and cooperation to improve the quality of life of residents in developing countries.

International student Titus Cooray is one of the high-level talents jointly trained by China and Sri Lanka. In 2019, he came to CEWE for a PhD. "My main research is nanofiltration technology, and China's research in this area is at the forefront." Qure recently introduced in an interview with "China Science News" that traditional reverse osmosis water treatment methods are more expensive, and nanofiltration Technology is more cost-effective and not only filters out all the salt in the water, it also retains some of its minerals.

In addition, the center also allows students to participate in international conferences to learn about the cutting-edge progress in their field, organize site inspections for relevant technologies, and allow students and visiting scholars to participate in bilateral cooperation projects. "This will allow the theoretical knowledge to be put into practice, and it will also help to promote China's water industry to go global." Wei Yuanxian said. Considering that the number of people visiting or studying in China is small and the impact is relatively limited, CEWE also sends overseas training for some countries in the “Belt and Road” strategy. The students cover the government, research institutes and industrial institutes. power.

Clean water nurtures friendship, walks into CAS-TWAS Center for Excellence in Water and Environment

She is currently doing research in the Key Laboratory of Drinking Water Science and Technology of the Chinese Academy of Sciences under the guidance of Academician Qu Jiuhui and Researcher Liu Ruiping, who is currently studying in Bosan. "My research direction is to remove organic arsenic in water by using iron-manganese adsorbent. I have made one result and two other papers are ready to be published." She said that Chinese friends are very cooperative and friendly, and she is honored Can learn in such a good atmosphere.

To this end, the center boldly innovates in the content and approach of personnel training. In terms of course setting, CEWE starts from the water industry chain, covering both the technology and management of the entire process from water source to water purification. At the same time, the lecturer team is not limited to the ecological center, but also includes experts and scholars invited from the Ministry of Housing and Urban-Rural Development, the Ministry of Environmental Protection, and the Chinese Academy of Sciences.

In 2019, a seminar was held in the TWAS China office, and she was deeply impressed by the one-week exchange. "There are many experts here who are studying technologies related to water quality and water treatment, and also have a good experimental environment, so I chose to obtain a doctorate degree here whenever I had the opportunity," she said.

"Double Material" Scientific Research Staff

Tista Joshi

For Qurei, in recent months, with the deepening of cooperation between China and Sri Lanka, he has become a "double source" scientific researcher who not only does scientific research, but also promotes communication and exchange in the cooperation between the two sides.
