The cultivation of comprehensive talents in the field of modern engineering requires interdisciplinary integration. Using interdisciplinary integration as the starting point, reform and practice of experimental teaching was conducted in the inorganic and analytical chemistry experiment course. Using the tap water and domestic sewage in the campus as the object of this study, the chemical oxygen demand was measured using the potassium permanganate method. The experimental aims were to improve the interdisciplinary thinking, data calculation, and practical problem-solving abilities of the students and to enhance their awareness of environmental protection, which is desirable for students majoring in chemistry, environmental engineering, and resource cycle science and engineering. The questionnaire revealed that students and teachers gave a high evaluation to the experimental content, and the experiment achieved good teaching practice results.
