“Short-flow clean water process with immersion ultrafiltration membrane technology as the core” passed the high-end identificati

At the beginning of the new year, Li Guibai, academician of the Chinese Academy of Engineering, and Song Renyuan and Shen Danian, consultants of China Urban Water Supply and Drainage Association, and other seven famous experts in the water supply and drainage industry, Pacific Water Treatment Engineering Co., Ltd., Nantong Water Supply Company, Suzhou Lisheng Water Purification Technology Co., Ltd. and Jinzhou Environment The “Small Process Water Purification Process with Immersion Ultrafiltration Membrane Technology as the Core”, which was jointly researched by the Technology Center of the Group Co., Ltd., was identified.

 

The result proposes a short process technology with immersion ultrafiltration membrane technology as the core, integrating flocculation, ultrafiltration and sludge concentration; this technology highlights the concept of low transmembrane pressure difference and low flux, making full use of the water plant The original work head saves energy; the membrane unit operation mode is adopted to reduce membrane pollution, the system runs stably, the effluent turbidity is less than 0.02 NTU, and the biosafety is greatly improved; the process saves land and saves investment for old water The plant renovation and new water plant have provided a new technical route, which is in line with the development direction of resource-saving industrialization and has broad market application prospects.

 

This achievement combines the conventional treatment process of water plant, the characteristics of process structure and the needs of process modification, and aims to improve water quality. The short-flow water purification process with immersion ultrafiltration membrane technology as the core is studied, and on this basis, The “Reed Water Plant Process Renovation Plan” is practical and feasible, and has a demonstration significance after implementation.

 

After discussion by experts, it was agreed that the project results were innovative and reached the international advanced level.

 

After more than one year of research, Pacific Water Treatment Engineering Co., Ltd., Nantong Water Supply Company, Suzhou Lisheng Water Purification Technology Co., Ltd. and Jinzhou Environmental Group Co., Ltd. Technology Center have overcome various technical and experimental difficulties and obtained A large number of quantitative data and parameters, the current results of small test and pilot test performance, stable performance, outstanding advantages, with industrial conditions. The high-standard identification of the results was successful, and experts agreed that it has reached the international advanced level, providing a new process route for China's water supply industry, and is also very suitable for the transformation of old water plants, which is a breakthrough in China's water supply technology research. It has a very positive impact on the development of the entire water supply and drainage industry.
