The "membrane filtration-draining integrated technology and its application", jointly developed by the Institute of Process Engineering of the Chinese Academy of Sciences and Guangdong Zhongkebao Biotechnology Co., Ltd., passed the identification of scientific and technological achievements organized by the Chinese Academy of Sciences on December 28, 2011 in Zhanjiang, Guangdong. . The appraisal committee consisted of 9 academicians including Gao Congchang, Academician Hou Li'an, and Professor Wang Shichang from the Hangzhou Water Treatment Technology Research and Development Center of the State Oceanic Administration, the Second Artillery Engineering Design and Research Institute, Tianjin University, Guangzhou Branch of the Chinese Academy of Sciences, and Shanghai Institute of Applied Physics , Guangzhou Institute of Biomedicine and Health, Institute of Chemistry, China Ion Exchange Resin Industry Committee, Beijing University of Chemical Technology. Academician Gao Congjun served as the director of the appraisal committee. After examining the equipment operation in detail, the experts of the appraisal committee carefully listened to the project host Wan Yinhua ’s research and development technology summary report, the project team member ’s use report and the scientific and technological innovation report, reviewed the relevant information, and conducted a full discussion. With inquiries. The expert group unanimously believes that the project innovatively proposes a new membrane separation technology that uses concentration polarization to achieve efficient solute concentration-membrane filtration-sucking integration technology, which simultaneously converts the concentration in the concentration polarization layer online in real time during membrane filtration Concentrated solution is exported to achieve multiple purposes such as membrane fouling control, high concentration, improving biological product activity recovery rate and reducing process energy consumption; this technology is a transformation of traditional membrane concentration principles and implementation methods, and has significant originality and independence There is no similar report on intellectual property rights at home and abroad. The appraisal committee unanimously agreed that the "membrane filtration-absorption integrated technology and its application" passed the appraisal, believed that the invented "membrane filtration-absorption integrated technology" was at the international leading level, and recommended to accelerate the promotion and application of the technology. Concentration polarization is an inherent phenomenon in the process of membrane separation, and is one of the key factors that affect membrane flux and cause membrane fouling. All along, both academia and industry have invested a lot of manpower and material resources in an attempt to eliminate or reduce the effects of concentration polarization to the greatest extent. Researcher Wan Yinhua and members of the research group innovatively proposed a new membrane filtration-draining integration technology using concentration polarization phenomenon through reverse thinking, and successively with the support of the National Natural Science Foundation of China and major scientific research equipment development projects of the Chinese Academy of Sciences, Developed "Ultrafiltration-Draining Integrated Technology and Equipment for Biomacromolecule Concentration" and "Reverse Osmosis-Draining Integrated Technology and Equipment for Seawater Desalination", which provides bio-product concentration, sea water utilization and other related industries A new technical approach has a significant application prospect. The appraisal meeting was chaired by Cao Ning, deputy director of the Bureau of Planning and Finance of the Chinese Academy of Sciences. He fully affirmed the achievements of the "membrane filtration-absorption integrated technology and its application" project, hoping to accelerate the industrialization of the project. Changjiang Ming, deputy research institute of process engineering, hopes that the project will be promoted and applied as soon as possible to provide scientific and technological support for social and economic development.
