Abstract: Currently, the practical teaching cannot meet the goal of talent training because students lack the opportunity to operate the equipment and observe the details of the project in the field trip of sewage treatment plant. To solve this problem, a complete set of VR-based teaching software for sewage treatment plant was developed by means of the UE4 and C4D. This software contains one virtual experiment center and 13 cases of sewage treatment structures. Students are able to experience the complete process of sewage treatment, as well as master the principle of sewage treatment, the structure construction and the equipment layout. What’s more, students can operate engineering equipment, and control the main process parameters in the software. Through the online and classroom teaching, VR practical teaching and assessment feedback, students can understand the sewage treatment plant comprehensively. The teaching software of sewage treatment plant based on virtual reality is complementary to traditional teaching, which provides a solution to the problem of the poor practical teaching of environmental engineering. As survey results show, the VR teaching software achieves the goal of environmental engineering practical teaching.
