Fujian promptly developed a powerful tool for epidemic prevention during the Winter Olympics.

Only 5 seconds of irradiation is needed to complete disinfection and sterilization, which is expected to cut the hidden cold chain transmission chain of COVID-19!

On January 23, the three pre opening villages of the Beijing Winter Olympic Games Winter Olympic Village, the disinfection and sterilization equipment located in the logistics warehouse of the Beijing Winter Olympic Village, started disinfection and sterilization the luggage, sports equipment, etc. entering the Winter Olympic Village, firmly holding the first barrier of epidemic prevention and control for the Winter Olympic Games. This is the first cold chain virus UV photocatalysis compound killing machine in China, and the only large-scale surface disinfection and sterilization equipment approved for use in the Beijing Winter Olympics in China, marking that this equipment has the ability to guarantee the highest level sports events in the world today.

Previously, the spread of cold chain logistics COVID-19 was highly concerned at home and abroad. At the beginning of January 2021, Yin Li, the newly appointed secretary of Fujian Provincial Party Committee, proposed to research and develop equipment for disinfection and sterilization COVID-19 by physical means such as light source when conducting research in the Science and Technology Department of Fujian Province.

As is well known, there is a huge "gap" between scientific research achievements and the market. How did this product achieve a "thrilling leap" and transform from research and development to market in just over six months?

On January 26, Chen Qiuli, Director of the Science and Technology Department of Fujian Province, told the Science and Technology Daily reporter: "Fujian Provincial Party Committee and Government gathered a team of academicians Fu Xianzhi from Fuzhou University and Dr. Chen Jian from Fuxia Science and Technology, and quickly overcame key core technologies such as UV photocatalysis. At the same time, the main leaders of the Provincial Party Committee and the Provincial Government personally coordinated and promoted, and all departments worked together to get through the key links of achievement transformation such as the disinfection and sterilization evaluation, on-site verification, product filing, and application promotion of the 'UV photocatalysis killing machine' P3 experiment, creating a rare 'Fujian science and technology speed' in the country, and creating a 'sharp tool' for science and technology to serve the Winter Olympics at the first time. ”

Becoming the 'only one in the country' to guard the first checkpoint of epidemic prevention

Winter is the key season for the spread of the epidemic. During the Beijing Winter Olympic Games, foreign competitors and team members were heavily imported, and there was a risk of COVID-19 transmission in their luggage and articles. How to achieve the goal of "preventing people, materials, and environment together" and fulfill the application commitment on schedule? This is a must answer question for China to prepare for the Winter Olympics under the epidemic.

"This disinfection and sterilization machine has been reviewed by the Technology Department of the Beijing Winter Olympics Organizing Committee as a product for epidemic prevention and scientific research, and a total of 9 machines are used in the main venues of the Beijing Winter Olympics." According to Chen Jian, photocatalysis is known as "the most ideal purification technology in the world today". Experiments have proved that the removal rate of all indicator bacteria by this machine at minus 18 ℃ can reach 99.99% in 5 seconds, providing a convenient, fast, harmless and power saving technical means for cold chain logistics and disinfection and sterilization of bulk commodities.

Previously, 20 sets of this killing machine have been promoted and applied in the cold chain supervision centralized warehouse in Fuzhou, Ningde and Zhangzhou, as well as in important scenes such as Fuzhou Post, Fuzhou University, Union Hospital and fruit wholesale market. Since the on-site verification in Fuzhou cold chain supervision centralized warehouse began in mid July 2021, 5500 cases of imported cold chain food were sampled, 55 positive samples were found, and all nucleic acid tests turned negative after being disinfection and sterilization.

New mechanism creates rare 'Fujian technology speed'

"One month for prototype, three months for virus evaluation, three months for test certificate, and put into use as soon as possible". Under the coordination of the main leaders of the Fujian Provincial Party Committee and the Fujian Provincial Government, the province launched a scientific research emergency mechanism, and all departments worked together to promote the UV photocatalysis compound disinfection and sterilization equipment project, creating a rare "Fujian science and technology speed" in the country. The Provincial Department of Science and Technology issued relevant opinions on strengthening the scientific research work of COVID-19 prevention and control, planned from the aspects of project establishment, research and development, platform layout, industry cultivation, etc., led the establishment of a cold chain disinfection and sterilization scientific research team, mobilized superior scientific research forces, and fully promoted emergency research; More than 20 coordination meetings were held to coordinate the Provincial Health Commission, the Department of Industry and Information Technology, the Market Supervision Bureau, the Department of Environmental Protection, the Provincial Center for Disease Control and Prevention, Fuzhou City, etc., to promote the completion of key links such as P3 experiment disinfection and sterilization evaluation, on-site verification, and product filing, so that the product could be launched in the shortest time, and passed the demonstration of national experts composed of academicians Hou Li'an, Zou Zhigang, etc.

At the same time, leaders of the Science and Technology Department of Fujian Province have led teams to report to leaders of the Ministry of Science and Technology, the National Health Commission and the National Bureau of Disease Control for many times. Relevant leaders of the Ministry of Science and Technology have led teams to Fujian for research and guidance, and held special coordination meetings with the Winter Olympic Organizing Committee to coordinate and promote UV photocatalytic disinfection machines into the Winter Olympic Games; The National Health Commission and the National Bureau for Disease Control and Prevention entrusted the Environmental Institute of the National Center for Disease Control and Prevention to organize a seminar on disinfection technology, actively promoting physical disinfection and sterilization technologies such as light sources to be included in the guidelines for the prevention and control of novel coronavirus pneumonia. In addition, we jointly held the promotion meeting of scientific research achievements in epidemic prevention and control with Fuzhou City, and the activities of the torch scientific and technological achievements through train (Fujian Station) of the Ministry of Science and Technology. At the Hainan International Health Industry Expo, we focused on introducing UV photocatalytic disinfection machines to all provinces (cities, districts) in China to help products enter the national market.

"It is not only necessary to show Fujian's scientific research achievements in international sports events, but also to comprehensively summarize Fujian's experience in project establishment, R&D, promotion and application of scientific research achievements in epidemic prevention, organize R&D and launch more new technologies and new products, and contribute to Fujian's programs and capacity-building for national epidemic prevention and control." Chen Qiuli said that Fujian will continue to strengthen the cultivation of COVID-19 disinfection and sterilization industries such as UV catalytic disinfectors, focus on supporting a group of leading enterprises, and strive to make disinfection and sterilization industry bigger and stronger.

In Fujian, the first set of "industrial electron beam cold chain virus disinfection and sterilization equipment" in China, the first "ultra high power deep ultraviolet LED portable disinfection instrument" and a number of "hard core technology" anti epidemic achievements have been launched successively, providing strong scientific and technological support for normal epidemic prevention and control and ensuring people's life and health.
