Abstract: In the view of the lack of comprehensiveness,openness,and low degree of freedom,the teaching system of Comprehensive Experiment of Environmental Chemistry was studied,the existing course system structure was optimized,and a targeted new course system was established. The teaching system emphasizes the student-led teaching method,with great freedom and exploration,highlighting the cultivation of comprehensive abilities of students. The newly established teaching system is comprehensive,openness,as well as exploration,which can provide a reference for the teaching of Environmental Chemistry in higher education.
