Water Pollutant Emission Standards Will Be Further Standardized And Stricter.

At present, Chinese textile and garment enterprises are facing a great change: the water pollutants discharge standards are further standardized and stricter.

According to the first financial reporter, the national environmental protection standard "textile industry water pollutants emission standards" (Draft) is being consulted inside and outside the industry. The consultation unit involves up to 87 government departments, industry organizations and key enterprises.

Most index limits are stricter than those of developed countries.

The preparation group of "water pollutants discharge standards for textile industry" introduced that since 2015, experts from the establishment group began to investigate and research, covering various types of manufacturing enterprises in the textile industry. After that, it lasted for more than 4 years after the discussion, technical review, and research and discussion.

"Some of the current standard limits and industry benchmark drainage are too loose, which is not conducive to guiding technological progress. The risk of toxic and harmful pollutants and biological toxicity has not been noticed. " Introduction to the establishment group.

The textile industry is a traditional pillar industry and an important livelihood industry of our national economy. It is also an industry with obvious international competitive advantages. It plays an important role in prospering the market, expanding exports, absorbing employment, increasing farmers' income and promoting regional economic development.

China's textile industry has a complete industrial chain, with cotton, wool, hemp, silk, chemical fiber, textile weaving, dyeing and finishing, knitting, home textiles and industrial textiles and other raw materials and products of the comprehensive development of the industry.

The introduction of dyeing and finishing industry is the main source of pollution in the textile industry. Dyeing and finishing industry has a large volume, including desizing, scouring, bleaching, mercerizing, dyeing, printing, finishing and other processes. The sewage produced has the characteristics of large volume, high concentration, most of them are alkaline and deep color. It is a kind of sewage which is difficult to deal with in industrial sewage, which poses a serious threat to the safety of environment and water resources. Shandong, Jiangsu, Zhejiang, Inner Mongolia, Hebei and other wool textile enterprises and wool textile enterprises accounted for 70% of the total sewage and pollutant emissions.

The notice issued by the State Council on the plan of action for the prevention and control of water pollution puts forward a number of requirements for the textile dyeing and finishing industry, including all the production projects that seriously pollute the water environment which do not conform to the state's industrial policies, such as small dyeing and finishing, dyestuffs, and so on. Dyeing and finishing industry to transform low water dyeing and finishing process. Along the main stream of the seven major river basins, environmental risks such as chemical fiber manufacturing, textile dyeing and finishing are strictly controlled, and production facilities and storage facilities for dangerous chemicals are rationally arranged. We should promote the orderly relocation of polluting enterprises and close them according to law.

The draft proposed that the discharge limits, monitoring and supervision requirements of water pollutants produced by textile enterprises and textile production facilities are stipulated. In order to reduce the emissions of toxic and harmful pollutants, two indexes of acute toxicity and luminous bacteria acute toxicity of Daphnia magna were increased.

"Generally speaking, most of the criteria specified in this standard are stricter than those of similar industry standards in developed countries." The establishment group said. For example, the limit of chemical oxygen demand (COD), the draft is "80 mg / L", while the Japanese uniform standard is 12080 mg / L, and the German textile manufacturing and fabric finishing standard is 16080 mg / L.

The introduction of the new standard is applicable to the discharge management of water pollutants in the existing textile enterprises and textile production facilities, as well as the environmental impact assessment of the construction projects of the textile industry, the design of environmental protection facilities, the acceptance of environmental protection for completion, the management of pollutant discharge permits and the discharge of water pollutants after commissioning.

Will affect many textile and related industries

According to the 2017/2018 China textile industry development report issued by China Federation of textile industry, at present, the number of Enterprises above Designated Size in China's textile industry is about 20187 (including fiber synthetic manufacturing and textile machinery manufacturing enterprises), among which the most enterprises engaged in cotton textile and dyeing finishing are 51% of the total number of textile enterprises.

In April this year, Cao Jiachang, President of the China Textiles Import and Export Chamber of Commerce, said at the "2019 China Asia Textile International Forum" that the problem of labor shortage and rising cost of textile and garment enterprises still exists.

Cao Jiachang believes that the leap from OEM (OEM) to ODM (independent design and R & D) and OBM (private brand export) is the fundamental basis for China's textile and garment to maintain export competitiveness. Intelligent manufacturing and transformation and upgrading are inevitable choices for Chinese textile and garment enterprises to maintain export competitive advantage.

The above research group introduces that the development of China's textile industry is relatively mature at present. However, the improvement of economic level and the decline of the proportion of working age population make it difficult to recruit workers in recent years, labor costs continue to rise, and the cost of industrial land is rising.

Due to the advantages of labor costs, Southeast Asian countries have begun to undertake some low-end manufacturing capacity in other countries. Textile manufacturing and export trade have increased rapidly, and textile manufacturing centers have shifted to Southeast Asian countries. Vietnam and other Southeast Asian countries enjoy superior international trade environment, and preferential tariffs have been developed in developed countries such as Europe and the United States, which have developed rapidly in recent years.

The textile and garment industry is Vietnam's third largest export industry. In 2016, its exports amounted to US $28 billion. In the first 6 months of 2017, Vietnam's exports of garments, textiles, fibers and yarns rose sharply. 48.3% The growth rate is very fast. Vietnam's textile and clothing products are exported to 40 countries and regions in the world, and larger markets such as the United States, Japan, Korea, China, the European Union and so on, have a certain relationship with the export of China's textile industry. Competitive relationship.

According to the first financial reporter, the strict discharge standards of water pollutants will affect many related industries.

Judging from the output of cotton textile products above Designated Size, cotton yarn production is mainly in provinces such as Shandong, Henan, Hubei and Hebei. Cotton production is mainly concentrated in Shandong, Jiangsu, Zhejiang, Hubei and Hebei provinces.

Judging from the output of wool textile products above Designated Size, the production of wool (wool) is mainly in provinces such as Jiangsu, Hebei, Shandong and Henan, and the production of wool fabric (woolen) is mainly concentrated in Jiangsu, Shandong and other provinces.

Judging from the output of silk textile products above Designated Size, the provinces with the largest production of silk are Guangxi, Sichuan, Jiangsu and Zhejiang. The spun silk production is mainly concentrated in Zhejiang and Guangxi, and the provinces with the highest output of silk woven fabrics and interwoven products are Zhejiang and Sichuan provinces. Shengze, Changxin, Xiuzhou, Longhu, Siyang, Ping Wang and Keqiao seven chemical fiber filament fabrics have the largest capacity.

As of September 30, 2018, the national sewage permit management information platform open system, dyeing and finishing industry issued a total of 3846 emission permits, including five eastern coastal enterprises accounted for 84.97% 。

However, according to the establishment group, the implementation of the new standard has obvious benefits in reducing emissions. The analysis of the environmental (emission reduction) benefits of the linen textile industry shows that the direct emission limit of the textile industry is increased from 100 mg / liter to 80 mg / liter, and the direct discharge of COD in the textile industry can reduce 270 tons / year, and the ammonia nitrogen reduction can reach 54 tons; dyeing and finishing process is the largest part of the textile industry's drainage volume, with an annual drainage capacity of about 15 million tons. After the implementation of the new standard, the adjustment of pollutants such as base displacement and ammonia nitrogen will lead to a significant reduction in sewage and ammonia emissions.
