Printing and dyeing in his speech

As an important part of the textile industry chain and a key link between the preceding and the following, it has made important contributions to break through the bottleneck of the development of the textile industry. As the main link in the use of textile chemicals, energy consumption and precipitation, it is the bottleneck for the whole industry to break through the inadequate ecological environment and achieve the goal of energy saving and emission reduction.

Li Lingshen pointed out that, at present, green development is the inevitable requirement of building a high-quality modern economic system and the fundamental policy to solve the problem of environmental pollution.

Energy saving, low carbon, recycling, efficient and sustainable green development is the only way to cultivate new industries such as new industries, new formats and new models. It is the fundamental way for printing and dyeing industry to break through the constraints of resources and environment, solve the pressure of energy saving and environmental protection, and realize pformation and upgrading.

In this regard, he put forward several development directions; first, efforts should be made to cultivate new technologies for sustainable development of the industry and lay a solid foundation for tackling pollution control. Second, we must speed up the construction of the green manufacturing system in the industry and comprehensively coordinate the promotion of green development; third, we must conscientiously implement the industry environmental policies and regulations, regulate the path of pformation and upgrading of the industry; fourth, we should continuously strengthen the social responsibility of enterprises in environmental protection, and carry out the responsibility oriented green industry positioning.

Finally, he said that the industry needs to achieve innovation, leading, intensive, efficient and quality oriented green development. There is still a long and arduous road to go. We need the concerted efforts of all industry workers to jointly explore countermeasures for tackling the tough problems in environmental protection, and provide new development power and create new demands for the industry through the energy saving and environmental protection technology revolution.

In recent years, with the change of printing and dyeing process and product structure, the water quality of printing and dyeing wastewater has also changed, and the difficulty of processing has also increased. It is an effective way to realize the sustainable development of printing and dyeing industry by controlling the source of pollutants and controlling the source of printing and dyeing wastewater.

Mao Zhiping, Professor of the school of chemistry and chemical engineering, Donghua University, published a special report entitled "the development of printing and dyeing cleaner production technology from typical pollutants in printing and dyeing wastewater". He analyzed the research background of typical pollutants in printing and dyeing wastewater and the results of typical pollutants in printing and dyeing wastewater. In the 27 enterprises in the printing and dyeing wastewater treatment technology, the research enterprises were equipped with sewage treatment plants, all of which were indirectly discharged, and 20 of them adopted three stage treatment technology, accounting for 74%. The treatment technology was mainly biochemical and physicochemical. The advanced treatment mainly adopted membrane separation technology, and the water reuse rate of the 6 enterprises reached more than 50%, accounting for 22% of the total number of research enterprises.

Among the 28 enterprises involved in the investigation of enterprise control technology, the application of control technology is mainly concentrated in the coloring process, including 50% of dyeing and 16% of printing. The control technology for pre-processing is 19% of the total number of cases, and 1 of the control technologies for functional finishing are 3%.

From the monitoring results of printing and dyeing wastewater, the excessive standard of metal antimony in printing and dyeing wastewater is very serious (chemical fiber), and the subsequent attention to the problem of excessive nickel will increase the impact on the printing and dyeing industry. The excessive standard of trimethyl tin compounds should also be paid attention to, and the source of cadmium ions needs to be determined.

He believed that the development direction of printing and dyeing cleaner production technology was mainly ammonia nitrogen, key technologies of total nitrogen reduction, total salt reduction technology and printing nickel screen substitution technology.

At the meeting, Lin Lin, Secretary General of China printing and dyeing industry association, read the twelfth batch of national printing and dyeing.

Directory of advanced technologies for energy conservation and emission reduction.

At present, the application of intelligent technology of dyeing and printing equipment has been more and more extensive. The combination of intelligent technology and numerical control system of China Heng Tian Li Xin International Co., Ltd. has led the development of the domestic dyeing and printing equipment industry. Through reasonable equipment selection and matching, Heng Tian Li Xin's products can form an excellent high-end digital dyeing and finishing workshop and digital factory.

Li Xin dyeing and Finishing Machinery Co., Ltd. CEO assistant Huang Junhua published a report entitled "one stop intelligent dyeing and finishing equipment for sustainable development and innovation", introduced his high le knitting flat production line, Gao Le equipment highlights, Viewtex platform.

With the increasingly stringent regulation of industrial waste gas, energy saving and emission reduction and waste gas treatment technology have attracted great attention in the industry. Exhaust gas purification and waste heat recovery and utilization are imperative. In improving environment, it can bring certain economic benefits to enterprises.

Zheng Jiehao, regional sales manager of Fuji textile machinery (Zhongshan) Co., Ltd. published a report entitled "new dual equipment for air purification and heat recovery".

Hohai University Professor fuck home issued a report entitled "printing and dyeing wastewater separation and recycling technology".

He proposed that the printing and dyeing enterprises should use the principles of environmental friendliness and comprehensive utilization of resources, use ecological environmental protection and high technology equipment, adopt clean production technology, improve the utilization ratio of resources, and control the amount of pollutants from the source of production.

Yao Hongqian, general manager of Shandong double wheel group Weihai Shuang Xin energy saving and environmental protection equipment Co., Ltd. introduced the energy saving and emission reduction solutions based on the heat balance and water balance.

The company has developed an industrial cascade thermal power conversion unit, and developed a three stage filtration technology consisting of "primary filtration - polypropylene fiber staple industrial filter cloth". It classifying the high-temperature waste water. The "double isolation multistage heat pfer technology" combined with the two level plate heat exchanger and heat pump technology is used to recover the heat of printing and dyeing high temperature waste water. The temperature of the waste water is cooled from 70-80 to 20-25 degrees, and the new water is heated from room temperature to 65-75 degrees C for production and use, and the energy efficiency ratio of the unit is more than 15.

The overall technology has reached the international advanced level.

Huang Beiyang, general manager of deborg Machinery Equipment Co., Ltd., Shunde District, Foshan, introduced the uniform application system of the auxiliaries of the company's molding machines. The system can directly finish the finished products and ensure that the wet cloth is finished.

The quality stability of the left, right, and middle and rear parts is the same, reducing rework, reducing the overall capacity of the drying process by more than 30%, and reducing the COD pressure of the sewage treatment.

In the afternoon, Zhao Qizhi, general manager of Panyu textile and dyeing Co., Ltd., published the "technology and application of high efficiency air pollutants treatment in textile printing and dyeing industry".
