In recent years, Baoji City in Shaanxi Province has increased its efforts in environmental protection. At the end of 2021, the Baoji Ecological Environment Bureau issued the Baoji City's "14th Five Year Plan" for ecological environment protection. In terms of controlling the source of odor, efforts are also being made continuously. Therefore, Shaanxi Wangtong Construction Project has commissioned Yiqing Environmental Protection to provide a supporting exhaust gas treatment device for its sewage treatment plant to eliminate odor and pollution during the sewage treatment process.

The first phase renovation project of the petrochemical industrial park sewage treatment plant: The design scale of the existing plant area of the petrochemical industrial park sewage treatment plant is 5 × 10000m/d, and the renovation scale is 5 × 10000m3/d. Yiqing Environmental Protection has equipped its sewage treatment plant with exhaust gas treatment devices to eliminate odors and pollution during the sewage treatment process.

Heli Group focuses on green manufacturing and invests a lot of attention in environmental protection. It also continues to make efforts in ecological environment protection planning and odor source control. Yiqing Environmental Protection has equipped its laboratory VOCs with exhaust gas treatment devices to eliminate odors and pollution during laboratory testing, production and manufacturing processes. The main sources of laboratory exhaust gas come from testing rooms, inspection rooms, operation rooms, and chemical storage rooms.

The Shanghai Tesla Superfactory is located in the Lingang Development Zone of Shanghai, and is currently the world's largest electric vehicle manufacturing enterprise, covering an area of 860000 square meters. It is China's first foreign-owned vehicle manufacturing project and also Tesla's first overseas factory. The second phase battery production workshop has battery coating and baking processes, which will emit a large amount of VOC pollutants. This project conducts sealed collection of exhaust gas from various production process lines, and after collection, it is treated by the end of the line exhaust gas treatment equipment before meeting the emission standards.
