At the invitation of the Nanjing Academy of Water Resources Sciences, Zhang Yafei, the chief scientist of the company, and Zhang Xiwu, the chairman of the company arrived in Nanjing on the morning of November 13, 2018. The two sides had in-depth exchanges on the technology and operation mode of the collaborative super-purification equipment (compound living water upgrading equipment). The symposium was held in Nanjing Water Resources Science Research Institute. The academy held.            

    Tang Yunqing, general manager of Ruidi Company of Nanjing Water Conservancy Research Institute, first delivered a speech, introducing the situation of Nanjing Water Conservancy Research Institute and its head office.            

     Starting from April 2018, the two sides have carried out mutually beneficial and mutually beneficial cooperation in many projects, such as Tiexinqiao in Nanjing, Daqing River in Xiongan New District, Shanghai Import Expo, Dianchi in Yunnan, Fengxian Xiangyang River in Shanghai, Shenzhen and so on. The cooperative projects have strong pertinence, including black and odorous water body/rich water body. Nutritional cyanobacteria enrich different types of water body/urban inland river/heavily polluted water body, and the effect of all cooperative projects is remarkable. The water body indexes of treatment projects are all upgraded from inferior class V water body to class IV or even class III water body.            

    At the same time, the two sides discussed the optimization of equipment operation parameters under different working conditions, the cooperation content of several specific projects, and the promotion cooperation mode of the two sides in the future.            

    The Symposium paved the way for the wide-scale promotion of water and soil co-management projects in large watersheds. It also laid a solid foundation for the further upgrading of co-ordinated super-purified water and soil co-management equipment. We look forward to greater achievements in cooperation between the two sides.
