China Fanca News News At present, new pollutants such as antibiotics and environmental hormone drugs have generally existed in various types of water environments around the world and threatened human health and ecological environment.In May 2022, the “Notice of the General Office of the State Council on Printing and Distributing New Pollutant Governance Action Plan” pointed out that it is necessary to strengthen the governance of new pollutants and effectively protect the safety of ecological environment and people’s health.
Film separation technology with ceramic membranes as the core is currently mainly used in two major areas of process separation and special water treatment.At present, the separation of ceramic membrane separation technology for new pollutants is facing challenges such as low activation efficiency of hydrogen peroxide and other oxidants, serious consumption of hydrogen peroxide, and difficulty in practical application.sex.In order to solve the problems of traditional ceramic film technology, it is urgent to develop new nano -catalytic ceramic membrane technology.
Recently, Tsinghua University Shenzhen International Graduate SchoolProfessor Zhang XihuiOn the basis of the development of nano -catalysts and catalytic ceramic membranes, the synthesis of high -efficiency catalysts such as manganese iron titanium system is carried out.The team first uses a simple step to regulate the α-Mno with the abundance of different oxygen empty levels.2Nano fiber material, realize H2O2Direct activation1O2, Lile the advanced nano theory support for the control of new pollutants in the water.
On the other hand, the team further screens high energy TI-MN3O4/Fe3O4The ternary catalyst limited domain in the ceramic film nano channel, successfully developedNew type of quantum inspiration state ceramic film, Can promote the inspirational state of electrons in the ceramic membrane hole, stimulate the density of electronic clouds, so that molecules such as dissolving oxygen and hydrogen peroxide in the water enter the excitation state, and quickly degrade new antibiotics and environmental hormones.%.
In addition, Zhang Xi’s team has built a new pollutant research base in Zhuhai, further promoting and applied to new quantum inspirational ceramic membranes, which is of great significance for domestic wastewater and pharmaceutical factory wastewater and pharmaceutical factories.The team will discuss the follow -up promotion of ceramic film with Zhuhai’s industry -university -research team.
