"Air Pollution Control Engineering (APCE)" is an important specialized course for majors in energy and power engineering.To further adapt to the highlights and features of the major curriculum design and to adapt to the new requirements for undergraduate students majoring in energy and power engineering, the writer conducted an exploration research on improving the teaching of APCE in terms of teaching content, teaching methods in particular engineering design and electronic practice, bilingual and/or English teaching.The results will provide a positive reference for the course of APCE closely-related majors.
