Tanning Industry Emission Standards Issued Small Or Weak Enterprises Or Eliminated

< p > it is reported that the water pollutants discharge standard of tanning and fur processing industry (gb30486-2013) will be formally implemented in March 1, 2014.

The introduction of this standard will definitely play a positive role in promoting a href= "http://www.91se91.com/news/list.aspx ClassID=101112107102" > leather industry < /a > improving the level of environmental protection, and accelerate the pformation and upgrading of the industry by strictly controlling the standards.

< /p >

< p > to implement the laws and regulations of the People's Republic of China environmental protection law, the law of the People's Republic of China on the prevention and control of water pollution and the law of the People's Republic of China on marine environmental protection, protect the environment, prevent pollution, and promote the progress of production technology and pollution treatment technology of tanning and fur processing enterprises, the Ministry of environmental protection issued the "discharge standard for water pollutants in leather and fur processing industry" for the first time.

< /p >

Less than p ago, China issued the "discharge standard for water pollutants in leather and fur processing industry" and "discharge standard for pollutants in battery industry". These two new emission standards play an important role in enhancing emission control of heavy metal pollutants.

< /p >

< p > it is reported that the problems such as the large amount of sewage discharged from the tanning industry, the complexity of sewage components, the uneven level of pollution control and the low promotion of cleaner production in the industry are prominent problems.

At present, the industry produces 1.6 million tons of waste water annually, of which COD is about 404 thousand tons, ammonia nitrogen is 16 thousand tons, and total chromium is 1280 tons. The current comprehensive emission standards are relaxed, the threshold for entry is low, and the pertinence is not strong.

The emission standard for water pollutants in leather and fur processing industry has clearly defined the indicators of total nitrogen and chloride ions and other characteristic pollutants that should be mainly controlled in the tanning and fur processing industrial wastewater discharge, and tightened the emission limits and the basic drainage index according to the development of water pollutants treatment technology in the industry.

After the implementation of the new standard, it is estimated that the annual COD and ammonia emissions can be reduced to 11800 tons and 2380 tons respectively.

< /p >

< p > Shishi has the famous textile, chemical raw materials and chemical products manufacturing, metal surface treatment and heat treatment processing enterprises, such as Kuan Hing leather, Xingye leather, "a href=" http://www.91se91.com/news/list.aspx "ClassID=101112107107", "Fuhua weaving" /a "and so on. As the second pillar industries after the textile and garment industry and the Shishi leather shoes industry and its products with an annual output value of more than 5 billion yuan, the new standard is not only conducive to reducing the emission control of leather tanning pollutants, but also optimizing the industrial structure, prompting a number of enterprises that are backward in production equipment, low in technological level, and imperfect in environmental pollution control facilities, and small and weak enterprises are eliminated.

< /p >

< p > the new standard has increased the entry threshold for the industry. The implementation of the new standard will accelerate the elimination of backward production capacity, and urge a group of enterprises that are backward in production equipment, low in technological level, imperfect in environmental pollution control facilities, and small and weak in the market.

It is estimated that about 10% of the leading enterprises (above 200 thousand sheets of cattle hide or more) need to further strengthen environmental management and upgrade some of the links. About 45% of the medium enterprises (above 50 thousand mark sheets and cattle hide) need upgrading and upgrading. Some upgrading enterprises will face the pressure of elimination, and about 45% of the small enterprises will be eliminated.

< /p >

< p > this standard specifies the discharge limits, monitoring and monitoring requirements of water pollutants in tanning and fur processing enterprises, and specifies the special discharge limits for water pollutants in key areas.

The air pollutants (including odorous pollutants) and environmental noise emitted by tanning and fur processing enterprises shall be applicable to corresponding national pollutant discharge standards, and the identification, treatment and disposal of solid wastes shall be applicable to the national solid waste pollution control standards.

< /p >

< p > China has the largest scale of leather production in the world, and the problems such as large volume of sewage discharge, complex sewage components, uneven level of pollution control and low promotion of cleaner production in the industry are prominent problems.

At present, China's tanning industry produces 1.6 million tons of waste water annually, of which cod is about 404 thousand tons, ammonia nitrogen is 16 thousand tons, and total chromium is 1280 tons. The current comprehensive emission standards are relaxed, the threshold for entry is low, and the pertinence is not strong.

The water pollutants emission standard for tanning and fur processing industry (gb30486-2013) has clearly defined the indicators of total pollutants such as total nitrogen and chloride ions and so on, and has tightened the discharge limits and the benchmark discharge quota according to the development of water pollutants treatment technology in the industry.

< /p >

< < p > the new standard is fully implemented. It is estimated that the annual cod, < a href= "http://www.91se91.com/news/list.aspx ClassID=101112107105" and ammonia nitrogen emissions in China's leather industry can be reduced to 11800 tons and 2380 tons respectively, with a reduction rate of 57.2% and 67.4% respectively. At the same time, the industrial structure will be optimized, and a batch of enterprises with backward production equipment, low technology level, and imperfect environmental pollution control facilities and small and weak enterprises will be eliminated.
