Not long ago, Keqiao district's first national key R & D plan "research and demonstration of printing and dyeing wastewater near zero discharge and resource utilization technology" was launched and implemented in Zhejiang Yingfeng Technology Co., Ltd.
Under the background of stricter environmental protection policy, the green and low-carbon transformation of printing and dyeing industry is imminent. The project of "research and demonstration of printing and dyeing wastewater near zero discharge and resource utilization technology" can not only promote the green transformation of printing and dyeing industry, but also greatly reduce the pressure of sewage treatment, which has broad market application prospects.
Textile printing and dyeing industry is an important link in the whole textile industry chain. Through the implementation of the "near zero discharge" project, the region has established the key technology system of near zero discharge of printing and dyeing wastewater, accelerated the upgrading and transformation of printing and dyeing wastewater project, improved the reuse rate of salt and the economy of the whole treatment process, realized the front-end interception and resource reuse of printing and dyeing wastewater, reduced the treatment cost of the whole water body, and finally promoted the printing and dyeing industry to be green, economic and efficient development.
High pollution has always been a pain in the development of printing and dyeing industry, and its pollution is mainly concentrated in printing and dyeing wastewater. Therefore, it is urgent to explore a treatment method to achieve near zero discharge of printing and dyeing wastewater, solve the problems of large water consumption, high salt consumption and organic pollutants pollution in wastewater, and realize the dual reuse of water and salt in wastewater. To reduce wastewater discharge, the key is to separate the water and pollutants, overcome the shortcomings of the existing wastewater treatment process, such as complex, long process, large consumption, heavy secondary pollution, etc., and constantly improve the wastewater separation and quality separation and utilization technology, so as to realize the reduction, harmlessness and resource utilization of wastewater treatment.
Shaoxing provides personalized solutions according to the actual needs of printing and dyeing enterprises, so that more enterprises can share the technological dividend, and promote the nearly zero discharge of wastewater in the whole printing and dyeing industry. Around the development goal of "high-tech, intelligent and green" in the printing and dyeing industry, actively prepare for the establishment of digital economy industrial park, and cultivate a number of Internet service platforms and enterprises of textile printing and dyeing industry, such as "Yingfeng technology", "printing and dyeing brain". While actively promoting the intelligent transformation of printing and dyeing enterprises, it is also necessary to vigorously extend the upstream and downstream industrial chain of intelligent printing and dyeing such as equipment and logistics, so as to lay a solid foundation for building a national "intelligent manufacturing" highland.
On the 15th anniversary of the concept of "two mountains", Shaoxing expects that the technology of "near zero discharge" of printing and dyeing wastewater will become the scientific and technological support to promote the energy conservation and emission reduction of printing and dyeing enterprises, and promote the transformation and upgrading of the printing and dyeing industry, and present a "green answer sheet" for building an "important window", displaying "Shaoxing scenery" and promoting the construction of "waste free city".
