In the company's exhibition hall, the teachers and students of the study tour group first watched the corporate promotional film, and then gained a comprehensive understanding of Tonghuan Environmental Protection Group's development history, industrial layout, and corporate culture from the development timeline and partner wall. From the profound accumulation in the early days of its founding to its current deep cultivation in the environmental protection field, a clear development blueprint unfolded before the students. 

Immediately afterward, the staff gave a detailed introduction to the company's important honorary qualifications and core patented technological achievements over the years. Each weighty honor and patent not only witnessed Tonghuan Environmental Protection Group's solid strength in environmental protection equipment manufacturing and technological innovation, but also deeply impressed the young students present with the innovative vitality and sense of responsibility of an environmental protection enterprise.

What is learned from books is superficial; true knowledge requires practice. 

Subsequently, under the guidance and safety instructions of the staff, the study tour group went deep into the production workshop for on-site observation. At the workshop site, the staff focused on providing detailed explanations of the company's three core process equipment: intelligent modular integrated technology, municipal malodorous waste gas treatment technology, and low-temperature sludge drying technology. From the design and structure of the equipment and processing techniques to the operating principles in practical applications, teachers and students listened and observed while engaging in lively discussions on technical details from time to time. Theoretical knowledge from textbooks collided with physical equipment in the workshop, and the workshop was filled with a strong atmosphere of academic and practical discussion.
