Abstract: For a long time, the talent training system for science and engineering majors has the problem of valuing "professional skills" over "humanistic skills". As a typical science and engineering major, students of environmental engineering major shoulder the important task of environmental protection. In order to cultivate environmental engineering professionals with coordinated development of "knowledge, ability and quality", the education system of environmental engineering specialty needs to be improved urgently. Article expounds the knowledge, ability and value, to shape the connotation of "the trinity" collaborative education system, analyzes the "trinity" collaborative education system in environmental engineering specialty construction, the necessity of implementing, finally combining with the characteristics of environmental engineering, environmental engineering major is discussed practicing path of "the trinity" collaborative education system, in order to guide the cultivation of high-quality talents in the field of environmental engineering.

Key words: Environmental engineering, Trinity, Value shaping, Practice path
