Science Island nano water purification technology fills the domestic gap

the "high fluorine water" with fluorine content exceeding 2-3 times the national standard enters a large "jar". Through the "baptism" of nano materials, it can be "transformed" into safe drinking water meeting the national standard in more than ten minutes. This technology from the Institute of intelligence, Hefei Institute of matter, Chinese Academy of Sciences has become a reality project in Mengcheng, and has also received frequent praise from Xie Sishen, chief scientist of the national nanoscience center and academician of the Chinese Academy of Sciences

Science Island nano water purification technology

high fluorine water with fluorine content more than 2.3 times the national standard enters a large jar. After baptism of nano materials, it can be transformed into safe drinking water meeting the national standard in more than ten minutes

this technology from the Institute of intelligence, Hefei Institute of matter, Chinese Academy of Sciences has become a reality in Mengcheng, and has also been frequently praised by Xie Sishen, chief scientist of the national nanoscience center and academician of the Chinese Academy of Sciences

five years ago, researcher Liu Jinhui introduced the blueprint of nano water purification to the Institute of intelligence, Hefei Institute of materials, Chinese Academy of Sciences. Five years later, when approaching this project again, it has changed from the idea of scientists to the water purifier of more than 40000 villagers in Yizhen, Mengcheng three according to different uses. It only takes more than ten minutes for groundwater to enter a specific instrument to be purified, and the cost of a ton of water treatment is less than one yuan

located in Sanyi Town, Mengcheng County, the country's first nano fluoride removal industrialization demonstration project has made Binzhou and Zouping the most competitive aluminum deep processing industry cluster in China. It began operation in July this year. It can treat 2400 tons of water per day. The fluorine content in the water before treatment is 2.0 to 3.3mg/l (the national standard is 1.0mg/l). The fluorine content in the water after treatment is as low as 0.55mg/l, which has solved the drinking water problem of about 50000 people in this town

the expert group headed by Xie Sishen, chief scientist of the national nanoscience center and academician of the Chinese Academy of Sciences, praised it, saying that it filled the domestic gap and was at the international leading level

Xuezengquan, a member of the expert group and professor of Peking University, said that the nano fluoride removal technology born in Science Island is better than the traditional adsorption method in effect. At the same time, the cost is much lower than the membrane separation method commonly used in developed countries. China's 50million people who drink high fluoride water for a long time are expected to benefit from it

Dr. Kong Lingtao, a researcher of Science Island and the technical director of Zhonglin Zhongke, said that unlike the traditional water purification device, the technology used in the demonstration project is to accurately grasp and spread the excess fluorine, so that other useful trace elements will not be filtered out together, and a part of fluorine can be retained in the water to meet the normal needs of the human body by controlling the contact time between water and nano materials

the nano water purification technology of science island also has the advantage of low price. The cost of treating a ton of water is less than one yuan, and the cost of the commonly used membrane separation method is about 5 yuan. Kong general can be introduced by Ling Tao more than 100000 times

when these nano materials are used and retired for 5 years, they can also be transformed into building materials

in the demonstration project of Mengcheng, the water purification device occupies a large room. In the future, the mini version of the water purification device is expected to appear and enter the family

next, the R & D personnel of Science Island will concentrate the nano water purification technology on small equipment, and the household nano water purification device can realize the deep purification of drinking water
