With the rapid development of artificial intelligence technology, its application in the field of education is becoming increasingly widespread. This paper introduces the functional features of the Kimi Intelligent Assistant and elaborates on its application in the teaching of Water Pollution Control Engineering course from aspects such as assisting in lesson plan design, creating mind maps, answering questions, process design, exercise compilation, and extracurricular extended learning. Challenges and countermeasures of introducing Kimi Intelligent Assistant into the course teaching are analyzed from the perspectives of technology integration, teacher training, student acceptance, data security and privacy, cost, and curriculum content updates. The paper also provides a prospect for the further application of the Kimi Intelligent Assistant, suggesting that it is expected to become an important tool in promoting the technological development of future environmental engineering education.
