Abstract: The experimental teaching link is an important guarantee for the cultivation of high-quality innovative talents. In this paper,taking the Guangdong University of Petrochemical Technology as an example,it discusses the reform of environmental engineering experimental teaching in the context of applied technology transformation in local Universities. Strengthening the experiment of professional "engineering" by optimizing the connotation of the main experimental course project. Actively explore the "project-based" innovative experimental model. Make full use of simulation experimental techniques and other measures to ensure that the experimental teaching links play an important role in the application of innovative environmental protection talents.
