The New Standard Of Textile Printing And Dyeing Industry Is More And More Strict.

　　 Spin What are the hot issues facing the industry? In addition to the headaches of cotton prices, the other is the issue of energy conservation and emission reduction. China held in April 2013 textile industry At the third session of the third session of the board of directors of the Federation, Wang Tiankai, President of the China Federation of textile industry, stressed the current situation of energy conservation and environmental protection facing the textile industry: the quantitative tasks and new emission standards required by the state and local governments in energy saving and environmental protection, as well as the pressure from public opinion and environmental organizations at home and abroad, which not only made the textile enterprises faced with problems such as arduous task of transformation and upgrading, increased investment and tight funds, but also appeared in the printing and dyeing industry.

Challenges come from new standards.

"The pressure of environmental protection is really great, and the new standard is getting stricter and stricter!" Hua Wei Limited by Share Ltd and chief engineer Luo Wei Xin joined many textile enterprises in this Council.

The new rule Luo Weixin mentioned is from January 1st this year. Textile dyeing and finishing Discharge standard for industrial water pollutants. The new revised standard tightened the emission limits of COD (chemical oxygen demand), five day biochemical oxygen demand, suspended solids and ammonia nitrogen to a greater extent than the original standards. At the same time, more stringent water pollutant emission limits were set for environmentally sensitive areas, and indirect emission limits were set up to strengthen supervision and management of wastewater discharged from public sewage treatment systems.

"The latest national standards clearly stipulate that the direct and indirect emissions of chemical oxygen demand (COD) from existing enterprises are 100mg/L and 200mg/L since January 1, 2013, which gives most textiles Printing and dyeing enterprise It has brought a lot of pressure. When local governments implement these policies, they can not leave much buffer time for enterprises. The pressure of printing and dyeing enterprises is very great. " Deputy Secretary General of China Textile Industry Federation, China textile industry Sun Huaibin, deputy director of the Federation's environmental protection and resource conservation promotion committee, told reporters.

Fu Jishu, chief engineer of Zhejiang Yi Zhuang printing and dyeing Co., Ltd., said: "most of the emission limits of this standard have been improved compared with the standard of 92, and we have expressed our approval and support." But he also expressed his doubts: there are some problems in the new standard, such as the partial displacement of some unit products, the partial limit of the unit product's reference displacement, and the inconsistent trend with other relevant national standard limits. He suggested that leaders and experts should seriously study these problems and make updated versions as early as possible.

Shortly after the introduction of the new standard, the Ministry of industry and information technology released the first batch of enterprises that conformed to the "printing and dyeing industry access conditions", involving 97 printing and dyeing enterprises such as Baoding deer King Wool Textile Co., Ltd. and Gaoyang County Yikang dyeing and Weaving Co., Ltd. The first batch of printing and dyeing enterprises approved by the public is to set up learning benchmarks for printing and dyeing enterprises so as to promote the overall transformation and upgrading of the printing and dyeing industry.

The "12th Five-Year" development plan of the printing and dyeing industry shows that by 2015, the energy consumption per unit of industrial added value has decreased by 20% compared with that in 2010, and the discharge of industrial added value water has decreased by 30% compared with that in 2010. The discharge of major pollutants has dropped by 10% compared with that in 2010. "These data are difficult indicators for printing and dyeing industry, but at the same time, these are inherent requirements for transformation and upgrading of the printing and dyeing industry." Li Jinbao, President of China printing and dyeing industry association, said.

Song of fire and ice

In fact, the printing and dyeing industry under the pressure of standard has created a song of fire and ice on energy conservation and emission reduction.

　 Printing and dyeing industry The total energy consumption has been controlled and the energy consumption per unit product has decreased. Public information shows that in 2005~2010, the amount of fresh water taken from printing and dyeing fabrics dropped from 4 tons / 100 meters to 2.5 tons / 100 meters, down 37.5%; the water reuse rate of printing and dyeing production increased from 7% to 15%, and increased by 8 percentage points; the comprehensive energy consumption of printing and dyeing production decreased from 59 kilograms of standard coal / 100 meters to 50 kilograms of standard coal / 100 meters, decreasing by 15%.

The management of water consumption, energy consumption and pollutant discharge in textile and dyeing enterprises has been strengthened step by step. According to Fu Jishu, the cleaner production of China's printing and dyeing enterprises has been for many years. Most of the printing and dyeing factories have passed the first round of cleaner production audit. Some enterprises have tasted sweetness after the first round of audit, and have conducted second audits. Most textile and dyeing enterprises have set up energy and water management institutions, and some textile and dyeing enterprises have achieved three levels of metering management for water consumption and energy consumption. At the same time, a complete regulation of water and energy management has been worked out.

"Although China's textile industry Printing and dyeing enterprise We have achieved certain results in energy conservation and emission reduction, but we must also recognize the problems encountered by China's textile and dyeing enterprises in energy conservation and emission reduction. Sun Huaibin told reporters that the COD emission of textile and dyeing industry ranks third among the fourth industries in the country and ammonia nitrogen emissions. The pressure of emission reduction is enormous.

He said: "at present, due to the large differences in economic development between different regions in China, and the support and supervision of different regions for energy conservation and emission reduction, there are obvious imbalance between clusters and enterprises, some do very well, but some areas are doing rather slowly, and there are no practical methods and measures."

China's textile and dyeing industry is a large energy consumption, high water consumption and high pollution. Public information shows that compared with foreign textile and dyeing enterprises, water consumption and energy consumption per unit product of China's textile and dyeing enterprises are about 2~3 times higher than that of developed countries. Printing and dyeing wastewater is characterized by large amount of water, deep color, high content of organic pollutants and large alkalinity. It belongs to the more difficult industrial wastewater. With the rapid development of textile and dyeing industry, the discharge and pollution level of printing and dyeing wastewater show a significant upward trend.

In addition, analysis of printing and dyeing industry production technology and printing and dyeing wastewater treatment technology at home and abroad, from the technology itself, China is not far from advanced countries. Many large printing and dyeing enterprises in China also attach great importance to energy conservation and emission reduction, and actively develop and apply advanced technology. However, advanced technology needs advanced production. equipment It is matched with the corresponding environmental protection facilities and requires a higher operating cost. China's printing and dyeing industry is a small profit industry, many small and medium-sized enterprises in the energy saving and environmental protection fund investment is quite insufficient, advanced technology in the industry has not been widely used.
