Q: What is the background for the development of textile standards?
Answer:The textile industry has a long history of development in China and is a traditional advantageous industry supporting the national economy and people's livelihood. Textile production process chain is long, product categories are complicated, the total amount of sewage discharge is large, and the concentration of organic matter is high. Among them, dyeing and finishing sewage contains toxic and harmful pollutants, which is difficult to deal. Previously, our ministry has issued four industry-type national water pollutant discharge standards for textile dyeing and finishing, hemp spinning, wool spinning, and silk reeling for the textile industry. Generally speaking, the scope of application of the current standards has not achieved full coverage of the industry. At the same time, there are problems such as lack of comprehensive toxicity control for dyeing and finishing sewage with high environmental risks, indirect discharge control requirements that cannot meet actual needs, and extensive regulations on benchmark discharge per unit product. In order to further strengthen the control of water pollutant discharge in the textile industry, prevent and control environmental risks, promote the optimization of industrial scale and layout, strengthen the management of small scattered, and at the same time effectively promote the management of the park system and coordinated pollution reduction and carbon reduction, and guide the green transformation of the textile industry, the Ministry of Ecology and Environment Jointly issued the "Textile Standards" with the State Administration of Market Supervision and Administration.
Q: What are the main considerations for the development of textile standards?
Answer:First, according to the law of pollution control, differential control. The Textile Standard implements the relevant provisions of the Ecological Environment Code, comprehensively standardizes the water pollutant discharge control requirements of the textile industry, and at the same time determines the water pollutant control items and discharge limits respectively according to the production process and pollution production characteristics of various sub-sectors, and puts forward differential control requirements according to the different whereabouts of indirect sewage discharge. Second, we will pursue science-based pollution control and green development. On the premise of ensuring environmental benefits, pollutant discharge units and industrial sewage centralized treatment facility operation units are allowed to negotiate and agree on emission limits conditionally, which not only reduces the pollution control pressure of pollutant discharge units, but also promotes the park system management, coordinated pollution reduction and carbon reduction, and achieves a win-win situation of environmental and economic benefits. Third, we will pursue precise pollution control and prevent risks. Adjusted and refined the benchmark displacement per unit of product, pollution control is more accurate, the level of fine management of the industry is further improved, for dyeing and finishing sewage and textile industry sewage centralized treatment facilities, increased zebrafish egg acute toxicity as a comprehensive toxicity control project, strengthen water environment risk prevention and control.
Q: What are the main contents of the Textile Standard?
Answer:The "Textile Standard" focuses on the problems existing in the current standards and the current needs of environmental management, and stipulates the requirements for water pollutant discharge control, monitoring and supervision and management of corresponding industry enterprises, production facilities and centralized sewage treatment facilities, so as to improve the level of fine management, strengthen the protection of water ecology, and promote the coordination of pollution reduction and carbon reduction.
One is to expand the scope of application and control projects. "Textile standards" to achieve full coverage of the textile industry, while the textile industry sewage centralized treatment facilities into the scope of application. At the same time, in order to strengthen the prevention and control of water environment risk, the acute toxicity of zebrafish eggs is stipulated as a control project to characterize the comprehensive toxicity of sewage for centralized sewage treatment facilities in dyeing and finishing production and textile industry.
The second is to optimize indirect emission control requirements. Differentiated control requirements are specified based on the distinct discharge destinations of wastewater. It is stipulated that new dyeing and finishing sewage disposal units shall not be discharged into urban sewage centralized treatment facilities, and existing dyeing and finishing sewage disposal units and other textile industry sewage disposal units shall implement indirect discharge limits for urban sewage centralized treatment facilities in accordance with regulations, and strengthen source control. Under the premise of not causing pipe network corrosion and siltation blockage, and the inflow of sewage centralized treatment facilities to meet the treatment capacity, when sewage is discharged to textile industrial sewage centralized treatment facilities and comprehensive industrial sewage centralized treatment facilities, it is allowed to negotiate and agree on the discharge limits of some pollutant projects.
Third, refine the benchmark wastewater discharge requirements per unit of product. Combined with the water intake quota standard, clean production technical standard and the production technology level of the industry, the benchmark displacement of wool textile, hemp textile, silk textile, dyeing and finishing products has been refined, and the benchmark displacement of chemical fiber weaving and industrial textile products has been added, which can effectively prevent dilution discharge, provide a clear basis for the determination of permitted discharge, environmental law enforcement and supervision, and promote water conservation and pollution reduction in the industry.
Q: What are the benefits of standards implementation?
Answer:The "Textile Standard" comprehensively strengthens the water pollutant discharge control requirements of the textile industry, which is conducive to promoting the emission reduction of characteristic pollutants and promoting the green transformation of the industry. The comprehensive toxicity control requirements stipulated in the standard and the strict discharge requirements for the centralized treatment of urban sewage will significantly strengthen the environmental risk prevention and control of dyeing and finishing sewage and strengthen the protection of water ecology. The standard allows sewage units to negotiate with downstream industrial sewage centralized treatment facilities to determine indirect discharge limits, which will promote industrial sewage centralized treatment facilities to take advantage of scale treatment, improve treatment efficiency, and reduce overall sewage treatment while increasing pollution reduction efforts. Energy consumption, drug consumption and carbon emissions of the system. Therefore, the implementation of the standard has significant environmental, economic and social benefits.
Q: How to ensure the implementation of standards?
Answer:One is to do a good job of standard publicity. Increase publicity and training efforts, through a variety of ways to do a good job of standard interpretation, and actively respond to public opinion concerns. Carry out training for local ecological and environmental authorities and related industries and enterprises to solve problems in the implementation of standards in a timely manner. Second, strict supervision of law enforcement. The competent department of ecological environment shall, in accordance with the standards, strengthen law enforcement, investigate and deal with environmental violations in accordance with the law, and promote the green development of the textile industry. The third is to strengthen technical assistance. Guide local governments to promote the orderly upgrading of pollution control facilities by relevant enterprises, comprehensively improve the efficiency of pollution prevention and control, and ensure that emissions meet the standards; guide textile enterprises and parks to standardize and negotiate emissions, and promote the green development of the industry.
