Abstract: Based on the concept of waste resource utilization and the foundational research in environmental engineering as a frontier subject, the undergraduate teaching experiment titled “Catalytic Degradation of Pharmaceutical Wastewater by Modified Red Mud-perovskite” is designed. The entire experimental process is divided into six parts: preliminary literature review, experimental design, material preparation and characterization, material performance and mechanism investigation, analysis and presentation of results, and experimental extension. Through a multi-stage design involving catalyst preparation, structural characterization, and performance evaluation, students have become familiar with the use of large-scale characterization instruments and deepened their understanding of the theoretical principles of catalytic oxidation. This experiment integrates cutting-edge scientific content into undergraduate experimental teaching, featuring advantages such as simple operation, clear phenomena, and excellent repeatability. It not only enhances students’ hands-on skills and innovative thinking, but also reinforces their teamwork capabilities and environmental awareness.
