In 2013, China's < a href= "http://www.91se91.com/news/index_c.asp" > dyestuff industry < /a > the situation faced by P is still grim and its internal and external environment is very complicated. On the one hand, there is no fundamental change in the international market environment. The global structural adjustment still needs a long period of time. Especially in the case of global profit reduction in the dyestuff industry, the export of most dyestuff products in China is blocked because of the reduced purchasing power of foreign demand customers, and it is more difficult to achieve the expected growth target. 
 green spanformation of dye industry is essentially to reduce energy consumption and reduce pollutants and greenhouse gas emissions in its production process. At present, in the production of dyestuff, there are many raw materials consumed, and the consumption per ton can reach several tons to tens of tons. At the same time, in its production process, it often needs one or more times of washing, and the water demand is very large, resulting in a large number of by-products or wastes, especially the amount of waste liquid generated is very large. Reactive dyes, such as reactive dyes, are the most popular dyes for cellulose fibers. Their annual output accounts for about 20% of the total dye and ranks the first in terms of dyestuffs. However, the utilization rate of reactive dyes is not high at present. Generally speaking, 60~65% is widely used in the dyeing process. The processing time after dyeing is relatively long, including washing, neutralization, soaping and fixing. It takes up 1/3 of all dyeing time. It not only takes a long time, but also has high energy consumption and water consumption, and produces a lot of difficult to deal with coloured salty sewage. Coupled with dye and dye intermediate waste water is the dye or dye intermediates produced in the process of wastewater treatment process, COD concentration is high. The basic raw materials for dye production are benzene, naphthalene, anthraquinones, aniline, nitrobenzene, phenols and so on. The loss of dye causes high COD concentration in water. For example, the effluent COD from a workshop of a dye factory in Inner Mongolia is as high as 170 thousand mg/L. 
 for the chemical industry of dye and dye intermediates, its water consumption and sewage discharge are the most important factors restricting its development. Therefore, dyestuff enterprises not only wear high energy consumption and high pollution "a href=" http://www.91se91.com/ "target=" _blank "hat" /a "for a long time, but also the focus of the local government's energy conservation and emission reduction work. In this regard, the pressure of dyestuff enterprises has been relatively large. If we do not do well in this area, we may be eliminated, which will directly affect the survival and development of enterprises. In particular, the dyestuff industry is facing enormous pressure. 
Therefore, green spanformation has become a prerequisite for the development of dyestuff industry. P Only with green spanformation can we achieve sustainable development. Of course, the key to green spanformation is how to do well in energy conservation and emission reduction, and step over the threshold of energy conservation and environmental protection. 
 the industry has entered a period of spanformation, and objectively requires enterprises to spanform to clean and green spanformation. In the future, enterprises that can survive in the market must be enterprises that do well in clean production and energy conservation and emission reduction. Cleaner production is to use environment-friendly production process in the dye production process, not only the energy consumption in the production process is reduced, but also the "three wastes" emissions will also decline. The benefits of industrial green spanformation are enormous. On the one hand, it is direct income. Direct income refers to the energy cost reduced by energy saving. Indirect benefits include avoiding technology locking, improving the trade environment and terms of trade, promoting the development of energy saving and environmental protection industries, and producing health benefits. 
In the long run, what are the direct economic benefits of industrial spanformation? In the long run, whether the cost is higher or the efficiency is greater? A general manager of a dyestuff enterprise in Shandong said that in recent two years, enterprises have been carrying out production management according to the requirements of cleaner production technology. P "Before the production of 1 tons of dye, about 30 tons of wastewater will be discharged. Now, through the implementation of clean production and technological innovation, we have been able to compress the waste water to less than 10 tons. In the past, a large number of waste alkali and waste acid were produced in the production process. On the one hand, the waste acid and base produced in the production process were reduced by using cleaner production technology, and on the other hand, the waste acid and alkali produced from the production process could be reused and reused. By improving the technology and implementing cleaner production, the production efficiency has been raised, the cost has been reduced correspondingly, and the discharge of pollutants has been significantly reduced, so that the pressure of energy saving and emission reduction has been reduced. " "Practice has proved that cleaner production has reduced our cost and raised gross margin. It not only improves the utilization rate of resources, improves production efficiency and economic benefits, but also substantially reduces waste, thus greatly reducing environmental pollution and influence. These advantages are enough to enable us to have the right to speak in the market competition. The boss said so. Therefore, the spanformation to green economy is the basis of "a href=" http://www.91se91.com/news/index_s.asp "dye > /a > industrial sustainable development.
