The State Will Formulate Standards To Cure Tanning Industry Pollution.

At present, the tannery industry in China is implementing the "comprehensive discharge standard for sewage (leather industry)", which is difficult to meet the needs of water environmental protection. According to the characteristics of tannery wastewater, according to the principle of combining environmental benefits and economic benefits, the "water pollution discharge standards for leather industry" should be formulated as soon as possible.

The two is to formulate the national tannery industry structure adjustment plan.

At present, many tannery factories in China are seriously polluted by excessive and excessive emissions, which is not conducive to the long-term healthy development of the industry. We should resolutely ban the leather enterprises below the scale and encourage the development of leather enterprises with low resource consumption, less environmental pollution, high technology content and good economic returns.

The three is to implement centralized pollution control.

We should give full play to the advantages of centralized development of the existing leather manufacturing and processing bases, and focus on tannery sewage treatment through expert design, special treatment and professional management, so as to ensure discharge of standards.

Four, we should continue to promote cleaner production.

We should vigorously promote the existing clean production technology, and increase scientific research investment in the end technology of chrome recovery and sludge treatment and clean production technology development in the whole process, and take the road of ecological leather making.

The five is to organize and carry out investigation and evaluation of leather industry.

On the basis of the investigation of the present situation of the industry, the guiding opinions and technical guidelines for water pollution control in the tannery industry are put forward, and the "11th Five-Year" plan for water pollution control in the tannery industry is set up.

Over the past 5 years, three enterprises in the tanning industry have accounted for 41% of the total number of enterprises. China is becoming the recipient of pollution in leather industry.

Two, small scale tannery enterprises wastewater discharge is difficult to meet the standards.

Because small and medium-sized tanneries are difficult to obtain economic and environmental benefits through large-scale production and centralized pollution control, they often cause large quantities of waste water to be discharged into the water body without treatment or after simple treatment.

Three, the "green barrier" has become the "bottleneck" that restricts the export of leather and its products.

According to statistics, in 2004 1~5, the leather garments and clothing exported to Guangdong by the European Union decreased by 69.1% and 61.2% respectively compared with the same period in 2003. The export of leather products to Zhejiang in Jinhua in 2004 decreased by 14.2% compared with the same period in 2003.

China's leather, fur and its products export value ranked first in light industry for 3 consecutive years.

In 2003, the leather industry above Designated Size Enterprises (annual sales volume of more than 5 million yuan) achieved 210 billion 300 million yuan of industrial output value, an increase of 20.9% over the previous year, and the total value of foreign trade import and export reached 26 billion 400 million US dollars in the whole year, of which 23 billion 200 million US dollars were exported, accounting for 5.3% of the total export volume of the country, accounting for 20.5% of the total export volume of light industry.

China's leather industry has obvious comparative advantages in terms of industrial resources and labor-intensive features. It has initially formed a special economic region with relatively concentrated layout in Wenzhou shoes making industry in Zhejiang, Zhejiang Haining leather clothing and Hebei Xinji sheepskin garments.

The data show that at present, China's tanning industry has annual wastewater discharge of about 1 billion tons, which is second only to papermaking and food brewing industry in light industry, especially in some concentration areas of leather making enterprises.

In terms of its characteristics, tannery sewage not only produces a large amount of wastewater, but also is a complex and high concentration organic wastewater. It contains a lot of harmful substances such as lime, dyestuff, protein, salt, grease, ammonia nitrogen, sulphide, chromate, and fur and pomace.

At the same time, because of the difference of raw materials (cowhide, sheepskin, pig skin), processing technology and finished leather (shoe upper leather, garment leather, sofa leather, luggage leather, etc.), the water quality of tannery wastewater is very different, and the difficulty of governance is increased.
