Environmental Protection, Energy Saving, Or Domestic Textile And Garment Industry Needs To Be Strengthened.

According to the 2012 environmental statistics, in the 41 industries surveyed and counted,

Wastewater discharge amounts to 23.7 billion tons, ranking third, chemical oxygen demand emissions 277 thousand tons, ranking fourth, ammonia nitrogen emissions 19 thousand tons, ranking fourth.

In the 972 national control sections monitored by the ten major river systems, the ratios of water quality to grade I, III, IV, V and bad V were 63.1%, 25.3% and 11.6%, respectively.

The main pollution indicators were chemical oxygen demand (COD), five day biochemical oxygen demand (CBOD) and total phosphorus (tbod) and Liaohe River, Huaihe River and Haihe River system. The total number of IV-V and bad V sections exceeded 50%.

Especially in the eastern region where economic development is relatively fast, pollution is the heaviest.

Strengthening environmental governance has reached an urgent level.

"Now the state's access policy for printing and dyeing is becoming stricter and stricter. The indirect discharge standard of wastewater has been raised to CODCr200mg/L, and the sensitive area has even reached CODCr60mg/L. The state does not include the printing and dyeing sludge in the list of hazardous wastes. However, in the process of environmental management, the printing and dyeing sludge is treated as a hazardous waste; exhaust gas, sludge and elimination are everywhere.

A printing and dyeing enterprise owner in Shaoxing said that nearly more than 90 printing and dyeing enterprises in Shaoxing area have borrowed 1 billion 660 million yuan from the bank to raise funds for environmental protection this year.

From "national hazardous waste list", "textile and dyeing and finishing industry water pollutant discharge standards" to "environmental law guide of printing and dyeing enterprises", the pressure of environment has pushed the industry pformation and upgrading step by step, and the printing and dyeing industry shuffling is intensifying.

"In fact, the level of energy conservation and emission reduction and environmental protection in China is not low in the world at present, and the emission standards are higher than those in Europe and the United States. Why is the impact on the environment still relatively large? The main reason is that our industrial agglomeration is very high, and a large number of enterprises are concentrated in a very small area. Because of the cumulative effect, the impact on the environment is relatively large."

Chen Zhihua, President of the China dyeing and Printing Association, said that because the textile dyeing and finishing industry is a large water user, it is also a large household of sewage discharge.

In order to promote advanced environmental technology and experience, accelerate the pace of energy conservation and environmental protection in China, China

Since 2006, the association has started the "national printing and dyeing industry energy conservation and environmental protection annual meeting".

"Every environmental annual meeting is aimed at communicating and pushing factories in the key technologies of energy saving and emission reduction and upgrading and upgrading in the process of production."

Chen Zhihua said that in recent years, the technical level and product level of the entire printing and dyeing industry have been greatly improved. The proportion of advanced equipment in the industry has been continuously improved, and energy conservation, emission reduction, cleaner production and ecological safety have been steadily advancing.

Sheng Fa in Zhejiang

A special military fabric is placed in a prominent position in the product exhibition room of the limited company, attracting the attention of the visitors. This is the "nano functional military fabric".

"Compared with ordinary fabrics, the fabric has the characteristics of high strength, strong corrosion resistance and good permeability. It is widely used in military clothing and equipment manufacturing."

Yang Wenlong, chairman of Sheng Fa textile, said that only this fabric can bring 100 million yuan output value to Sheng Fa textile in one year, accounting for 1/4 of the company's annual output value.

In order to make innovations, Sheng Fa textile is willing to invest, invest 150 million yuan to introduce advanced equipment and technical personnel, develop new fabrics and printing and dyeing technology, and look for experts in three ways to establish cooperation between Donghua University and Xi'an Polytechnic University, such as Shanghai, Xi'an Polytechnic University and other universities and research institutes.

And set up an expert workstation which is comparable to the national standard laboratory, Zhejiang Sheng Fa textile printing and dyeing Co., Ltd., which has injected vitality into the technological innovation of enterprises.

"For enterprises, the establishment of academician workstations is a forced pformation and upgrading."

In Yang Wenlong's view, "innovation is the solution to today's problems; creation is for tomorrow's goal."

Like Yang Wenlong, many printing and dyeing enterprises have been actively involved in this "green war".

Because they firmly believe that only the power of technology can change the future of enterprises and save the development of the industry.

"The textile industry is now at an extremely difficult developing moment, not only squeezed by the original textile giants, but also facing the competition of the developing countries in the economic development.

With the continuous tightening of the national environmental policy, the printing and dyeing enterprises must rely on industry university research cooperation to get out of the new way of technological innovation.

Yao Mu, academician of the Chinese Academy of engineering, pointed out that the sustainable development of the printing and dyeing industry must adhere to the twenty character policy of "innovation driven, quality first, green development, structural optimization, and integration of two technologies".

Please face the printing and dyeing.

Quite a lot of people will have a vivid view of all the printing and dyeing factories and waterloom factories in Wujiang this year.

As the local environmental protection authorities detected excessive antimony in the drinking water source of the Tai Pu River at the junction of Jiang, Zhe and Shanghai, then the "decisive" behavior was followed, causing the whole industry to panic.

To this end, Professor Xi Dali Li, a professor at Donghua University, pointed out that the source of antimony in textile dyeing and printing industry was mainly made of polyester (polyester raw material) in the publication of "countermeasures and thinking of antimony pollution in printing and dyeing industry". When 300~500ppm and three were oxidized, two antimony, antimony acetate or ethylene glycol antimony were used as catalysts for the synthesis of terephthalic acid and ethylene glycol. The flame retardants in dyeing and finishing were basically used without antimony compounds 3 years ago.

At the same time, Xi Dan Li also announced that the printing and dyeing enterprises measured: Antimony 100~500 g/L, which is more than 1000 g/L, and the water jet loom factory is about 30~100 g/L (1/4 enterprises have such a situation), entering the centralized sewage treatment plant 210 g/L, effluent 80 UG g/L.

"We hope that the relevant departments and organizations will find out the truth in time and give a fair answer to the printing and dyeing.

This is the case of nonylphenol, which is now contaminated by antimony. What happens after it is polluted? "

Although there is still a certain gap between China's printing and dyeing industry and the existing best technology and equipment consumption and energy consumption in the world, we can not deny the achievements made by the printing and dyeing industry in recent years.

Sun Ruizhe, vice chairman of the China Textile Industry Federation, introduced the "mid-term evaluation report" of China's textile industry in 12th Five-Year. It pointed out that in 2012, the comprehensive energy consumption of textile enterprises above designated size was 61 million 740 thousand tons of standard coal, which was 4.2% lower than that in 2010. The energy consumption per unit added value and the intensity of carbon dioxide emission decreased by 25% compared with that in 2010. The goal of the plan has been completed. Some indicators of emission reduction can not be continuously adjusted by statistical adjustment. It is estimated that the value added of the textile industrial unit in 2011 has dropped by 29.8% compared with that in 2010, and the target of "planning" has been basically completed.

In fact, the printing and dyeing industry still has many potentials to be explored in terms of technology, equipment and management, especially in accelerating the adjustment of industrial structure and product mix.

If we increase the proportion of knitted products, it will help reduce the overall energy consumption.

According to rough estimates, the energy saving per unit product will increase by 8%~12%, and the overall energy saving rate will be increased by 2%~6% when mixed with all products.

And the gradual improvement and popularization of new technologies and technologies, such as the promotion of cold rolling technology can save energy by 30%. "

Xi Dan Li said that if the investment in 2011 ~2015 pformation was calculated at 42 billion 520 million yuan a year, the investment in 2016 ~2020 will be calculated at 35 billion 640 million yuan per year, of which 30 billion yuan will be invested annually because of the increase in output and profits. The textile industry itself will be difficult to digest, and the state needs to give considerable encouragement policies, especially the reduction of a certain proportion of income tax, business tax and financial support for technological pformation.

Today, whether printing and dyeing enterprises, or printing and dyeing cluster, Shaoxing, Shishi and so on have increased the intensity and speed of environmental protection, making green printing and dyeing become a common practice.

The problem of environmental protection is not solved and realized by an enterprise or an industry. Therefore, we must combine various resources, integrate resources and integrate force so as to achieve a sustainable and healthy development of the industry.
