Improving water resource utilization efficiency in the textile industry: supercomputing empowers “ecological printing and dyeing”
Textile industry is a traditional pillar industry of my country’s national economy and the third largest source of industrial wastewater in my country. Therefore, how to improve water resource utilization efficiency in the textile industry is an important current research topic.
Today, through supercomputing empowerment, “ecological printing and dyeing” is no longer out of reach. The reporter learned today from the National Supercomputing Chengdu Center (hereinafter referred to as the Chengdu Supercomputing Center) that in order to accelerate the research and development of a new generation of textile industry wastewater treatment technology, optimize the design of the treatment process unit, clarify the working principle of the technology, and realize the full utilization of waste water resources, Chengdu Supercomputing Center and Chengdu Computing Dog jointly carried out computing work on the “Electroactive Membrane” project in conjunction with Shanghai Donghua University. Through the empowerment of computing power, scientific researchers can avoid taking “wrongful paths” on the road of scientific research and help build a green production and lifestyle.

With the help of “electroactive membrane” technology
Realize the “reduction, removal and resource recovery” of toxic pollutants
During the treatment of textile printing and dyeing wastewater, we often face difficulties in removing characteristic pollutants such as antimony and aniline. In view of its low concentration and high toxicity and other pollution characteristics, there is currently no mature and reliable treatment technology.
Facing the major demand for synergy and synergy of pollution reduction and carbon reduction in the textile industry, Professor Liu Yanbiao’s team at Donghua University has been committed to developing a new generation of electroactive separation membrane technology for advanced treatment of textile wastewater and resource recovery.
What is “electroactive membrane”? The reporter learned that electrochemical technology has application potential in chemical conversion, chlor-alkali disinfection and energy storage, while membrane separation has application potential in separation and purification. “Electroactive membrane” cleverly combines two technologies into an electroactive separation membrane. In today’s increasingly tense environment and energy issues, it is expected to solve water purification problems that are difficult to solve with traditional biological and chemical methods.
Computing power empowerment
Avoid taking the “wrongful path” on the road to scientific research
Professor Liu Yanbiao said that although the team has rich R&D experience and foundation in experimental research, and has achieved the removal of pollutants and recycling of resources within the range “visible to the naked eye”, it still knows very little about the underlying reaction mechanism. , the design of research topics is often carried out through “trial and error” methods, and many “wrong paths” are inevitably taken.
“We are also very interested in the binding sites of pollutant molecules on the surface interface of electroactive membranes, the interaction between reactive oxygen species and pollutant functional groups, and electron transfer pathways. However, the above process involves a large number of molecules and atoms Or the interaction mechanism between electrons is difficult to characterize through traditional experimental techniques.”
“With the help of the computing resources provided by the Chengdu Supercomputing Center, the team can accurately simulate the reaction process at the microscale, helping researchers to have a deeper understanding of the surface interface behavior and microscopic reaction mechanism at the microscale, and laying the foundation for the development of more efficient Electrode materials and electrocatalytic systems provide important guidance.” Talking about this cooperation, Professor Liu Yanbiao said.
On the other hand, in Professor Liu Yanbiao’s view, high-performance computing has greatly improved the team’s scientific research efficiency. In the initial design stage of electroactive membrane materials, the catalytic activity of different nanocomposite membrane materials was compared with the help of high-performance computing. and screening, which can effectively shorten the material development cycle and help the team carry out targeted scientific research work, which are beyond the reach of traditional research ideas.
The reporter learned that in the next stage, Professor Liu Yanbiao’s team will also make full use of computing resources to guide the later project design, promote the integration of the printing and dyeing processing industry chain with natural circulation, and realize “ecological printing and dyeing”.
