2. Short-range cycle and pollution control of used power batteries
The problems of low metal recovery and pollution can not be solved by treating the end of lithium battery waste recycling, we focused on electronic waste recycling, a new process for cleaning and recycling valuable metals based on selective lithium extraction was developed, and the key technology and core equipment of wastewater acid-base regeneration and medium circulation process enhancement have been exploited. It won the first prize of environmental protection science and technology in 2020.

3. Interfacial enhanced advanced oxidation removal of organic pollutants
The key technologies, such as free radical directed inhibition and in situ spectroscopic analysis have been developed and applied successfully in water pollution control. High efficiency catalyst was developed and large-scale production was realized, which effectively improved the production efficiency of reactive oxygen species. It won the first Prize of China Association for Analysis and Testing Award in 2020.
