In order to further promote the construction of the second phase project of the School of Petrochemical Engineering (Quangang Campus) of Fuzhou University, Chen Quancheng and his team of five from the School of Petrochemical Engineering of Fuzhou University visited our company on the morning of March 26, 2019 to investigate and understand the sewage treatment technology, determine the size and structure of the waste liquid pool in the experimental building, and the requirements of the factory building. After our technical personnel introduced the relevant technology, the technical route was preliminarily determined and detailed technical solutions will be provided to the school, laying a good foundation for future cooperation.
