Printing And Dyeing Industry To Step Up The "Threshold"

In 2011, the central economic work conference put forward that in 2012, energy conservation and emission reduction will continue to be strengthened, and energy conservation and emission reduction will be established.

The sequential batch activated sludge process (SBR process) is used to make emission reduction work a step further.

On the eve of the new year, the sewage treatment workshop of the two branch of Anhui Huamao textile Limited by Share Ltd is very busy.

With the relocation of the two branch plant, the daily sewage treatment capacity of the company gradually decreased.

However, the weaving workshop needs to do a lot of work to meet the requirements of the national comprehensive wastewater discharge standard.

It is understood that the industrial waste water produced by Huamao company in Anhui mainly includes washing waste water from the air conditioning room, boiler water film dedusting wastewater, boiler ash disposal wastewater, sizing wastewater, mercerized water and caustic water.

Now the actual daily handling capacity of the two branch plant is 150 tons per day, which is far from meeting the production needs.

Therefore, the company is going to adopt some new technologies, such as sequencing batch reactor (SBR) process.

Compared with continuous flow activated sludge process, the new process has the characteristics of simple composition, good sludge settling property, low SVI value and easy maintenance and management.

Lu Ji, director of the company's technical quality department, told reporters that in 2012, the company will continue to increase energy conservation and emission reduction efforts, pform some key equipment, and make emission reduction work to a higher level.

Another 3 million yuan will be invested to meet the three grade standard of comprehensive discharge standard for sewage.

Recently, the dyeing factory of Zhejiang Bai Shui printing and dyeing Co., Ltd. has racked its brains to make the sewage treatment meet the requirements of Shaoxing.

Zhejiang Shaoxing Environmental Protection Bureau stipulates that from July 1, 2012 onwards, all industrial waste water in the urban area which is incorporated into Shaoxing water treatment development Co., Ltd. will carry out the three level standard of the comprehensive discharge standard of sewage, that is, the concentration of chemical oxygen demand (COD) should be controlled below 500 milligrams per litre.

"In 2012, our company has to invest another 3 million yuan in sewage treatment," Xu Li, general manager of the dyeing and finishing enterprise division, told reporters: "in recent years, enterprises have invested about 20000000 yuan in sewage disposal.

Last year we invested another 7 million yuan for equipment upgrading.

At present, the company's COD emissions control is about 600 milligrams per litre. "

At present, there are more than 300 printing and dyeing enterprises in Shaoxing, and the "restriction order" of the Environmental Protection Bureau will undoubtedly increase the survival burden of some small and medium-sized printing and dyeing enterprises.

It is understood that the general printing and dyeing enterprise processing 1 tons of grey cloth cost is about 4 yuan, and the enterprise can only charge 2.5 yuan / ton ~3 yuan / ton processing fee, the cost pressure is highlighted.

If pollution control is further upgraded, it will lead to large losses.

Faced with increasingly stringent emission standards, many printing and dyeing enterprises will face pformation and upgrading.

"The threshold has been raised, and a large number of printing and dyeing enterprises must be killed."

A printing and dyeing enterprise Mister said without worry.

Exergy

Adopt energy saving and environmental friendly cold pfer printing technology.

In recent years, Shanghai Changsheng textile products Co., Ltd. has a better life, thanks to the cold pfer printing technology developed by them.

This technology is energy saving and environmental protection, representing the development direction of printing and dyeing industry.

Cold pfer printing technology can be widely used in home decoration, bedding, high-end children's clothing and women's clothing fabrics, leisure products and other textile products, and laid a solid foundation for the company's sustainable development.

In 2012, the company will further develop new product lines and expand exports.

Chen Guiwu, vice chairman of the company, is full of confidence in the new technology: "we will build a production base for computer color separation, digital printing, high efficiency printing and printing, and one-stop service pfer printing."

Trade Organization

The "four new exchange conference" will be held in April, focusing on the practice of printing and dyeing industry upgrading.

The China printing and dyeing industry association will hold the "four new exchange meeting" in April 2012, focusing on how to innovate the printing and dyeing industry through technological innovation, production equipment, chemicals utilization, product research and development, enterprise management and other aspects, so as to enhance the operation level of enterprises and achieve industrial upgrading.

How many years of printing and dyeing technology has been called, such as printing and dyeing high-efficiency short flow pre-treatment technology, anhydrous, less water printing and dyeing technology, low temperature, low salt, low alkali printing and dyeing technology and high value-added finishing technology, etc., if it can be widely promoted in the industry, on the one hand, it can improve the printing and dyeing enterprises' survival condition, on the other hand, it will also enhance the overall technical level of the industry.
