Since the beginning of the 21st century, global resource crises and environmental pollution have seriously threatened the survival, safety and healthy and sustainable development of human society. In the face of the severe decline of natural resources and the deteriorating ecological situation, international organizations and countries are all trying their best to actively respond.

　　On the one hand, it supervises resource conservation, improves resource utilization, and develops and utilizes new energy. On the other hand, it formulates various environmental protection regulations and technical standards for product ecological quality. All this aims to standardize and strengthen the rational use of resources by human society, treat nature well, and protect the natural environment on which mankind depends for survival.

　　The Chinese government attaches great importance to this aspect of work. It has formulated relevant laws and regulations very early, and put forward the binding indicators on environmental protection is a serious matter that cannot be changed and must be implemented unswervingly.

　　Cleaner production is a brand-new concept, but also a systematic project. Its core content is to further improve resource and energy utilization, reduce pollutant emissions, and reduce harm to humans and the environment through continuous improvement of management and technology.

　　The dye industry is not only a resource consuming consumer, but also the industry that produces the most pollutants. Therefore, it is imperative to fully implement and implement cleaner production in the dye industry. It is a top priority and the strategic direction of the development of my country's textile industry. The dye industry generates the largest number of pollutants. It is sewage and waste water. Printing and dyeing wastewater is an important source of water environmental pollution. my country is a major textile printing and dyeing country, and the water environment it faces is quite severe.

　　Symptoms need to be cured. The prevention and control of pollution is to start from the source. It is a consensus to reduce the amount of chemicals used in textile production and processing, improve the ecological quality standards of chemicals, prevent textile pollutants from spreading to water media, and reduce water The degree of pollution, reduce the discharge of wastewater, improve the recycling rate of resources and reduce the pollution to the water environment.
