Solve the worldwide problem of recycling and utilization of paper and pulping wastewater

Institute of Membrane Science and Technology, Nanjing University of Technology

Membrane is a special thin layer of material with selective transmission function, which can make one or several substances in the fluid pass through, and other substances do not pass through, so as to play the role of concentration, separation and purification. Separation membrane technology can achieve separation under the condition of maintaining the original biological system environment, and can efficiently concentrate and enrich products, effectively remove impurities, while convenient operation, compact structure, low energy consumption, simplified process, no secondary pollution, and no need to add chemicals. It has been widely used in the production process of biomedicine, food and beverage, chemical and petrochemical industries, environmental protection water treatment, gas purification, water purification and other industries.

With national research platforms such as the State Key Laboratory of Materials Chemical Engineering and the National Special Separation Membrane Engineering Technology Research Center, focusing on the major needs in the fields of water resources, energy, environment, and upgrading of traditional industries, It is engaged in the development of high-performance membrane materials such as inorganic ceramic membrane, pervaporation membrane, gas separation membrane, organic membrane, organic inorganic composite membrane, and the development of membrane integration technology and complete sets of equipment such as membrane reactor, wastewater recycling, tail gas purification, etc., which belongs to the strategic emerging industry supported by the State.

The Institute has always adhered to the market orientation of technological innovation, adhering to the development concept of "close to science and engineering", and built a five-part innovation system of "talent training, scientific research, service to society, base construction and industry cultivation", carrying out original basic research, developing disruptive technologies, and creating major engineering applications. Create a film industry technology innovation center through "science to technology, technology to product". The Institute implements the innovation model of "one institution, two systems, unified management", relies on the engineering center of the university mechanism, sets up PI academic team, bases on basic original research, and continuously produces high-level original achievements. Relying on the market mechanism of membrane materials institute and membrane application institute, set up a start-up team, engage in the "secondary development" of original achievements, set up a technology transfer team, and realize the transfer of technology appreciation.
