Production practice is an indispensable part of training students’ practical skills and cultivating application-oriented talents. At present, the production practice teaching mode of environmental engineering major in local applied universities is difficult to meet the needs of industrial upgrading. Therefore, this paper explores the course teaching reform by integrating ideological and political elements into the practice, using virtual simulation technology and auxiliary on-site video, so as to ensure that application-oriented engineering talents meet the needs of national development and provide reference for subsequent engineering professional practice.
