Helping the purification of printing and dyeing wastewater "Zhejiang Jin Membrane" won the honor

Recently, the scientific and technological achievements of "Key Technologies and Applications of Printing and Dyeing Wastewater Resource Utilization and Internet Online Monitoring" jointly developed by Zhejiang Jinme Environmental Technology Co., Ltd. and Tianjin University of Technology have passed a series of professional reviews by the appraisal committee led by well-known academicians. , and finally agreed that the technology of the achievement has reached the international advanced level, and won the scientific and technological achievement appraisal certificate issued by the Tianjin Science and Technology Evaluation Center.

After identification, the achievement contains many innovative points. Including the development of a high-strength submerged membrane filtration process technology (HMF) suitable for advanced treatment of printing and dyeing wastewater, compared with the traditional MBR process, the operating energy consumption is greatly reduced, and the cost of printing and dyeing wastewater treatment is more economical; research and development for advanced treatment of printing and dyeing wastewater and Resource utilization of new nanofiltration membrane materials and new preparation technology, the retention rate of magnesium sulfate reaches 99%, the retention rate of sodium chloride reaches 92%, the membrane flux is ≥ 25L (m2 h), and the reuse rate of purified water is greatly improved .

Through strategic cooperation with Tianjin University of Technology, "Zhejiang Jinmo" integrates resources based on their respective advantages and helps the project to tackle key problems smoothly. This achievement is technically difficult and innovative, and is suitable for the recycling of wastewater and salt reuse in printing and dyeing enterprises.

It is reported that this achievement has been applied and promoted in more than 40 printing and dyeing enterprises including Zhejiang Yingfeng Technology Co., Ltd., Zhejiang Yuejia Printing and Dyeing Co., Ltd., and Shaoxing Haitong Printing and Dyeing Co., Ltd., and the response has been good. "Next, we will stand at a new starting point, continue to increase investment in scientific research, transform major innovations into productivity, and help companies in the traditional printing and dyeing industry to bail out." The person in charge of the company said.
