1. Introduction to Engineering Laboratory
National Engineering Laboratory of Circular Economy was accredited by the China Circular Economy Association in 2022. The laboratory focuses on conducting application research and engineering technology studies in the field of safe disposal and resource utilization of saline wastewater, with a specific emphasis on the characteristics of radioactive saline wastewater's safe disposal and resource utilization, development of functional membrane materials and anti-pollution technology, waste salt purification, recycling and resource technology, as well as control technology for organic pollutants in high-saline wastewater. In order to address major key challenges and common technical issues related to the safe disposal and resource utilization of salt-containing wastewater, our aim is to develop a series of essential common technologies, products, equipment, and relevant standards within this field. This will expedite the establishment of a national strategic scientific and technological force while providing robust support for innovation hubs' construction and self-reliance in advanced science and technology.
