Abstract: Based on the concept of waste resource utilization and the frontier subject and research foundation in environmental engineering, the undergraduate teaching experiment of “modified red mud-perovskite catalytic degradation of pharmaceutical wastewater” was designed. The whole process of the experiment can be divided into six parts of previous literature research, experimental scheme design, material preparation and characterization, material performance and mechanism investigation, experimental results analysis and display, and experimental expansion. Students are familiar with the use of large characterization instruments through the design of multiple links of catalyst preparation, structure characterization and performance evaluation. This experiment introduces scientific frontier content into undergraduate experimental teaching, with the advantages of easy operation, clear phenomenon and good repeatability. It not only cultivates students' practical skills and innovative thoughts, but also strengthens their teamwork ability and environmental awareness.
