Abstract: At present, the environmental issues of our country are very complicated. The technology of most environmental equipment made in China cannot keep up with the current demand. The advanced environmental equipment from abroad does not adapt to the situation of our country. Therefore, training students with abilities of making advanced environmental equipment is pressing. Taking experimental device made by students’ own as an important part, this paper discussed how to improve the practical teaching system of the major of environmental engineering and analyzed how to develop the students’ practice skills and their innovative consciousness. Meanwhile, this paper described the effect of developing the students’ innovative thinking and practice abilities through the cases of experimental device designed by students’ own.
