The Total Control Is Closely Related To The Printing And Dyeing Industry &Nbsp;

Planning for printing and dyeing industry during the "12th Five-Year" period: acceleration in the eastern region

During the "11th Five-Year" period, the state implemented the total control of energy saving and emission reduction, and achieved a good effect on the total sulfur dioxide emission plan of the electric power industry.

In 12th Five-Year, emission reduction work became more sophisticated, and it was clearly proposed in some key industries.

The "energy saving and emission reduction comprehensive work plan" issued in 12th Five-Year (hereinafter referred to as the "plan") clearly stated that the state will focus on promoting energy saving and emission reduction in 11 industries, including the printing and dyeing industry, with clear objectives and tasks, strengthening industry guidance, and promoting technological progress.

This means that the printing and dyeing industry is not enough to meet the standards according to the current standards. In 12th Five-Year, we should focus on solving the existing problems in the industry, and further expand the space for energy saving and emission reduction.

Why will the printing and dyeing industry be included in the total control area? What are the problems existing in the industry? What measures will the industry take in the face of the pressure of "emission reduction in 12th Five-Year"?

The total volume is not the biggest. Why is it named? The high concentration of printing and dyeing enterprises causes great environmental pressure.

The printing and dyeing industry was quite surprised when it learned that it was included in the key control industry of 12th Five-Year emission reduction.

Although the plan proposes that the chemical oxygen demand and ammonia nitrogen in the paper and printing industry account for about 40% of the industrial emissions, compared with the papermaking industry, the volume of printing and dyeing is not so large.

According to Chen Zhihua, Secretary General of China printing and dyeing industry association, the chemical oxygen demand in printing and dyeing industry accounts for 7% of industrial emissions and ammonia nitrogen accounts for only 5%.

In an interview with our reporter, Chen Zhihua said that in China, the textile printing and dyeing industry has a large capacity and has entered the market earlier.

Objectively speaking, the overall operation level of China's textile and dyeing industry is in the middle class.

Over the past twenty or thirty years, with the shrinking of foreign textile and dyeing industry and the progress of domestic technology and management, China's textile and dyeing industry has become increasingly competitive internationally.

Why does such an industry that occupies an important position in the national economy be included in the total control area?

Wu Yueying, director of the total control room and senior engineer of the water environment planning department of the China Environmental Planning Institute, told reporters earlier that there were more structural problems in the printing and dyeing industry.

In addition, the degree of enterprise concentration is high. With the above scale enterprises (20 million yuan and above) statistics, the capacity of 5 provinces in Guangdong, Fujian, Zhejiang, Jiangsu and Shandong accounts for 90% of the whole country, while the capacity of Zhejiang alone accounts for more than 50%.

The structural problems of the industry and the high concentration of enterprises have caused tremendous pressure on the environment, so that the total control is closely related to the printing and dyeing industry.

Despite the "11th Five-Year" period, the Ministry of industry and the Ministry of printing and dyeing industry has been integrated, 2009~2011 plan to eliminate production capacity of 7 billion 500 million meters, and shut down many small workshops, small businesses, but the printing and dyeing industry's structural problems are still outstanding, but also need further adjustment.

In addition, in printing and dyeing process, the main characteristics are high water consumption, large displacement, high pollutant concentration and deep color in the effluent.

According to the report on prevention and control of industrial pollution in key industries in 2008, the average content of pollutants in China's printing and dyeing wastewater is 2~3 times that of abroad, and the water consumption is as high as 3~4 times.

Printing and dyeing wastewater is not only the main pollutant in the industry, but also has some problems in the treatment of sludge produced by printing and dyeing wastewater.

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 process technology needs advanced production equipment and corresponding environmental protection facilities, and requires higher operating costs.

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.

How to control the total amount in 12th Five-Year?

"Management in technology and technology in management" will be one of the main measures.

At the beginning of "12th Five-Year", the total amount of major pollutants discharged from the printing and dyeing industry was clearly stated in the plan.

This is a great test for the printing and dyeing industry.

At present, the discharge standard of pollutants used in printing and dyeing industry is still formulated in 1992, that is, the discharge standard for pollutants in textile dyeing and finishing industry (GB4287-1992).

Facing the "12th Five-Year" emission reduction pressure and emission reduction targets, the Ministry of environmental protection will speed up the introduction of new industry standards and have consulted the industry associations.

The new standard will increase the emission limits of pollutants, which indicates that the pressure of energy saving and emission reduction is greater and the cost of pollution control should be further increased.

During the "12th Five-Year" period, the trade associations will continue to introduce advanced and practical technologies to promote energy conservation and emission reduction, and will pay more attention to management and emission reduction.

Chen Zhihua said, "we will continue to promote technology, but management will also be strengthened to achieve equal emphasis on technology and management."

In terms of managing emission reduction, industry associations will help enterprises to establish energy saving and emission reduction management systems, such as the simplest reward and punishment system and assessment system.

A three level metering system should be set up to accurately measure water meters and meters to every machine platform, so that we can know where the energy consumption is high and where the energy consumption is low.

In order to carry out energy saving and emission reduction work according to specific procedures, we must put the measurement system in place.

The development of advanced digital management is also very critical. Using digital system to conduct on-line monitoring and system control of the whole process is not only more precise and more timely than manual control, but also makes energy saving and emission reduction more refined.

"Management in technology and technology in management" will be one of the major measures for energy saving and emission reduction in the printing and dyeing industry in 12th Five-Year.

In Shaoxing, the output value of printing and dyeing industry accounts for 53% of the total output of Zhejiang and 30% of the whole country, the management of emission reduction has begun to be implemented.

Not only has more than 100 printing and dyeing enterprises gathered in industrial parks, but also online monitoring has been launched.

From March to October this year, the Shaoxing city installed 43 meters for measuring sewage discharge in the urban area and installed IC cards on the flowmeter.

The IC card records the total amount of pollutant discharge in the enterprise. Once approaching the hyper line, the electronic valve will give an alarm to the enterprise and the environmental protection department. After the total amount is exhausted, the monitoring device will automatically close the valve and control the discharge of the sewage.

In addition, faced with the question of how to control the new capacity of the industry in 12th Five-Year, Chen Zhihua said that during the 12th Five-Year period, the capacity of the industry will grow at a low speed, and its annual growth rate will be around 3%.

Compared with the growth rate of capacity growth of more than 10% during the "11th Five-Year" period, 3% of the capacity growth rate is very slow, the industry can basically maintain the balance of existing capacity, and the amount of pollutant emissions will not be large.

Is it necessary to carry out large-scale industrial pfer?

Industrial upgrading in the East and moderate undertaking in the central part of the country do not advocate pferring to the West.

In view of the high degree of agglomeration in the printing and dyeing industry, and in order to alleviate the heavy pollution of heavy pollution, the plan points out that it is necessary to adhere to the new pformation and expansion project to carry out p regional adjustment, and from the super environmental capacity area to the area with surplus environmental capacity.

Chen Zhihua also recognizes that the printing and dyeing industry in the eastern coastal areas has achieved rapid development over the years, but the structural contradictions and problems that have accumulated over the years have become increasingly prominent, which has created a great pressure on the local environmental capacity.

For areas with high environmental pressure caused by high concentration of industries, should large-scale industrial pfer be carried out?

For printing and dyeing industry, industrial pfer is not necessarily the best choice.

Chen Zhihua said that when it comes to industrial pfer and environmental capacity rich areas, people often first think of the central and western regions, and in the past other industries, the pfer to the central and western regions has always been a trend.

But controlling pollution is not simply pferring the industry to the areas with abundant environmental capacity such as the central and western regions. The development of the central and western regions can not take the mode of "pollution first and post governance".

The plan for the printing and dyeing industry during the "12th Five-Year" period is: the eastern region accelerates the pace of industrial upgrading, the central region improves the manufacturing system of textile industry, and the western region focuses on the development of special industries.

The eastern region should rely on scientific and technological progress, eliminate backward production capacity, raise the level of energy conservation and emission reduction, and achieve industrial upgrading.

Because the relatively mature industry in the eastern region and the large-scale development of enterprises provide the economic foundation for industrial upgrading, we should take the road of industrial upgrading.

At the same time, we should control the development mode and appropriately reduce the production capacity on the basis of not expanding production capacity, so as to achieve the goal of reducing environmental pressure.

The central region can undertake a moderate portion of the enterprises that pferred the past, such as Hunan, Hubei, Jiangxi, Anhui and other water rich areas.

The water consumption of printing and dyeing industry is large, and the water resources in these areas are relatively abundant, which has the foundation of industrial development.

Moderate pfer of industries to the central region can alleviate the environmental pressure in the East, and there is also a trend of pfer.

"For the western region, we should focus on the development of special industries."

Chen Zhihua said.

Most of the western regions are short of water, and the demand for water consumption in printing and dyeing industry is not satisfied, and there is no foundation for development.

It can be seen that the printing and dyeing industry has taken full account of the expansion and pfer of the industry. Due to the characteristics of the large volume of water in the production industry, the industry still focuses on the upgrading of industries and other industries.

"This reflects that the printing and dyeing industry has formulated a suitable development path according to the characteristics of the industry in the face of the great pressure of" energy saving and emission reduction in 12th Five-Year ".

Chen Zhihua said.

What is the basis for deepening emission reduction?

From source control to terminal management, advanced and practical technologies need to be introduced.

Reporter Cui Yuchen reported that after the nationwide implementation of energy saving and emission reduction, the printing and dyeing industry, like other industries, has been unable to meet the requirements only by terminal governance.

Since 11th Five-Year, the industry has promoted cleaner production in every process of the whole production process, including energy saving, water saving and so on. It has been implemented through various measures such as process improvement, equipment modification and rational use of chemicals.

Trade associations also played a positive role in this period. According to statistics, 2007~2010 has launched 4 batch of 119 advanced technologies for energy saving and emission reduction to help enterprises carry out cleaner production and deepen energy conservation and emission reduction.

Chen Zhihua said that the introduction of advanced technology will continue, and the printing and dyeing industry will be included in the total control area. During the "12th Five-Year" period, they will introduce more advanced and practical technologies.

In November 3rd this year, in the fifth national printing and dyeing industry energy conservation and environmental protection annual meeting, the association also introduced fifth batch of advanced technologies, including 25 energy saving and emission reduction technologies.

"These energy-saving and emission reduction technologies cover the whole process from source control to terminal governance, and many advanced and practical technologies have been well promoted in the industry."

Chen Zhihua said.

They paid more attention to the promotion of practical technology, and even the old technologies that had been used and practiced before the reform and opening up were also promoted.

For example, the drying process of printing and dyeing plants will produce condensed water. In the era of state-owned enterprises, condensed water had been reused.

But after the reform and opening up, private enterprises abandoned this technology in order to catch production.

Now, with the increasing pressure of pollution control, in order to reduce production costs, the Trade Association launched the condensate water reuse technology at the first annual environmental protection annual meeting in 2006.

This technology has been widely applied in the two or three years since it began to popularize. Now, over 80% of the condensate recycling industry has been used in the industry.

Through the promotion of technology and the importance of environmental protection, during the "11th Five-Year" period, the average consumption of standard coal per 100 meter cloth fell to 15% kg from 50 kg, down 15% from the 59 kilogram, water consumption decreased from 4 tons to 2.5 tons, water consumption decreased by 37.5%, and the average water reuse ratio of enterprises increased from 7% to 15%.

Reporters learned that, in the annual printing and dyeing industry energy conservation and environmental protection annual meeting, industry and enterprises will not only exchange new technology, but also consult with experts about the use of existing technology or new technology.

This year's annual meeting also specially set up a discussion group on environmental protection and cleaner production technology, which mainly discussed energy saving, emission reduction, cleaner production, wastewater reuse and process technology, and answered the problems encountered by enterprises in terms of technology usage, providing ideas for more enterprises to further deepen energy conservation and emission reduction.

After the scientific assessment of dumping and dyeing sludge in Foshan, the treatment plan will be put forward.

Since April this year, black objects have been pported to an industrial area in Gaoming District, Foshan City, Guangdong province. Until October, the environmental protection department of Gaoming District was informed and investigated the source and composition of these black objects.

After preliminary judgement, the black object is printing and dyeing sludge, with an area of about 12~15 mu, and the depth is about 1~3.5 meters. The volume is about more than 20000 cubic meters, about twenty thousand tons.

Due to the large amount of sludge dumping, the incident became the largest dumping case in the history of Gaoming.

Printing and dyeing sludge contains a large number of toxic and harmful substances. It has been collected in Guangdong province strictly control waste list, from collection, storage to processing, disposal has a strict procedure, so the outdoor dumping is absolutely not allowed.

If it contains untreated heavy metals or other harmful substances exceeding the standard, it will pose a major threat to the surrounding environment and even human health.

Relevant departments were immediately informed of the establishment of the ad hoc group, the Gaoming District Transportation Bureau staff said, preliminary testing results showed that the sludge was not found to exceed the standard of pollutants.

Due to the large amount of sludge and huge volume, whether it contains harmful substances, it is necessary to make scientific sampling analysis. As a result of the long dumping time, sludge sewage has been showing signs of infiltration.

At present, Gaoming District has invited experts from Guangdong provincial environmental research department to formulate evaluation plans.

Through the assessment, it is found that only more than 20000 cubic meters of sludge can be scientifically tested and cost 960 thousand yuan.

Gaoming District Transportation Bureau official said that after the comprehensive inspection of science, the dumping of sludge pollutants is not exceeding the standard, otherwise the cost of treatment may reach 100 million yuan.

The cost of cleaning up this sludge is calculated at least two million yuan, according to the minimum standard of one ton of 100 yuan.
