Guide: The iron and steel enterprises cannot be satisfied with the original achievements. The basic mission of the iron and steel industry is to supply the society with high quality and quantity of high-performance steel products with low resource and energy consumption, low environmental and ecological loads, and high conversion power and labor productivity. The implementation of ultra-low emission transformation is an important strategic approach to green development of iron and steel industry.

The iron and steel industry is arranged according to the resolution plan of the CPC Central Committee and the State Council. Under the leadership of the ministerial joint meeting, the VOCs online monitoring system has made serious breakthroughs and achievements in the supply side structural reforms such as capacity reduction, screening of backwardness and banning of "ground bar steel". At the same time, in response to the resolution, the VOCs online monitoring system has made a firm decision to fight the pollution prevention battle, win the blue sky defense battle, and comprehensively manage air pollution in autumn and winter, The level of environmental protection and energy conservation of the iron and steel industry has been continuously improved, and the environmental management skills have been upgraded. A large number of clean and environment-friendly enterprises have emerged.

The statement at the 19th National Congress of the Communist Party of China has advanced the construction of ecological civilization and environmental protection to a new height, and proposed that environmental protection is an important livelihood and social issue. In the new era, the ecological environment has become one of the weak points in building a moderately prosperous society in an all-round way. Against this background, the environmental capacity and carrying capacity of important steel production areas such as Beijing Tianjin Hebei and its surrounding areas, the Yangtze River Delta, and the Fenwei Plain are increasingly constrained, and the people's demand for further improvement of environmental quality is extremely urgent, The Ministry of Ecology and Environment and other departments issued the Work Plan for the Transformation of the Iron and Steel Profession with Ultra Low Emission, which is the implementation and guarantee of strengthening pollution prevention and ecological construction and vigorously promoting green development proposed in the government's work statement, and will strongly promote the transformation and upgrading of the iron and steel industry and complete the high-quality development of the iron and steel industry.

1、 Persist in fulfilling the ultra-low emission of steel profession with high quality

（1） Fulfilling the ultra-low emission of steel profession is a powerful guarantee for winning the battle of blue sky defense.

The blue sky defense war is a serious resolution made at the 19th National Congress of the Communist Party of China. It is about meeting the people's growing needs for a better life, building a moderately prosperous society in all respects, high-quality economic development and building a beautiful country. The Ministry of Ecology and Environment, in the process of formulating the resolution plan of the Work Plan for Ultra Low Emission Transformation of Iron and Steel Enterprises, carefully conducted field research, listened to opinions from all sides, and based on a large number of online monitoring data, made several drafts, which was rigorous, scientific and pragmatic. In the process of implementation, the iron and steel industry should have more responsibilities and responsibilities. In order to complete the new policy proposed in the ultra-low emission transformation work plan of iron and steel enterprises, complete the whole process and whole process environmental management, effectively improve the development quality and environmental performance of the iron and steel industry, significantly reduce the emission of major air pollutants, promote the continuous improvement of environmental air quality, and complete the promotion of the green development level of professional enterprises, Provide favorable support for winning the blue sky defense war and continue to make contributions.

（2） The implementation of ultra-low emission of steel is a powerful means to improve the steel professional image and achieve harmony with the city and society.

The iron and steel enterprises can not meet the original achievements. The Work Plan for the Ultra Low Emission Transformation of Iron and Steel Enterprises not only puts forward clear requirements for the ultra-low emission policy after the end management, but also strengthens the requirements for the whole process, the whole system and the whole industrial chain, which is beneficial to better play the role of the iron and steel enterprises in energy transformation and social resource consumption, create a green industrial chain, complete the virtuous cycle of green production, and complete the iron and steel industry and the city Social harmony and integration.

As a major raw material industry, the iron and steel industry has a very basic mission, which is to supply the society with high quality and quantity of high-performance steel products with low resource and energy consumption, low environment and ultra-low CEMS system ecological load, high conversion power and labor productivity, and meet the needs of social development, national security and people's life.

（3） The implementation of ultra-low emission transformation is an important strategic approach to green development of iron and steel industry.

Low carbon green development is the core content and key point of the transformation and promotion strategy of the iron and steel industry, as well as the strategic policy of strengthening the iron and steel industry. As for the steel industry, environmental protection has also become the top priority for enterprises' livelihood and development. At present, the steel profession urgently needs to meet the challenge of ultra-low emission transformation. Promoting the implementation of ultra-low emission of steel industry is an important measure to promote low-carbon and green development of the industry and complete high-quality development. On the one hand, with the release of the national policy of resolving overcapacity and cracking down on "ground bar steel", the benefits of iron and steel enterprises have improved, the profitability of enterprises has been ensured, the conditions have become more favorable, and the transformation and promotion of environmental protection equipment and processes have certain financial guarantees. On the other hand, various management skills have also made a serious breakthrough. Therefore, the current stage is a favorable opportunity for iron and steel enterprises to implement ultra-low emission transformation and solve outstanding ecological and environmental problems; It is an effective way to further build a fair competition environment and ensure the high-quality development of the steel industry.

2、 Down to earth, honesty oriented to promote ultra-low emissions of steel industry

（1） The key to promoting ultra-low emissions is to know.

To implement the ultra-low emission of iron and steel industry, we must fully understand the subject of responsibility. There should be responsibility differentiation, performance and comments, and a certain organizational guarantee mechanism to ensure the completion of the transformation mission on schedule. We should increase capital investment, strictly control project quality, strengthen operation management, and attach importance to the use and improvement of new skills and processes. In order to meet the requirements of ultra-low emissions, we must make practical progress in rigid investment, use good skills, use ultra-low emission dust meters properly equipped, and avoid selecting "bean curd dregs" environmental management projects to reduce investment costs, which will affect the management effect. In the process of promoting ultra-low emissions, iron and steel enterprises and technical innovation and progress engineering skill source units should pay attention to integrity, not superficial, down-to-earth, honesty based.

（2） Systematically diagnose and optimize, formulate a scientific and reasonable ultra-low emission project transformation plan, and truly complete the systematic reduction of total pollutant emissions.

The whole profession should promote the layout adjustment and process structure adjustment according to the requirements of the ultra-low emission transformation work plan, and optimize the total output of the region; In combination with the development trend of environmental protection, formulate environmental protection strategies, carry out systematic diagnosis and optimization of the whole production process, and formulate a scientific and reasonable ultra-low emission project transformation scheme in combination with the actual situation and level of the enterprise, further reduce the unit consumption and emission intensity, and achieve a substantial reduction in the total emission of pollutants on the existing basis.

3、 The ultra-low emission transformation should make progress while maintaining stability and stand up to previous tests

We should focus on the needs of improving ambient air quality, follow the overall requirements of promoting the implementation of ultra-low emissions in iron and steel industry, grasp the rhythm and strength, make progress while maintaining stability, and orderly promote the ultra-low emissions transformation of iron and steel enterprises. It is hoped that in the process of implementing the Work Plan for Ultra Low Emission Transformation of Iron and Steel Enterprises, local governments should not rush for success. Regardless of the basic conditions of the enterprise, they should not only make clear the policy expectations for the enterprise in advance, but also give the enterprise a reasonable transformation period, a necessary buffer period and a habit period to ensure the production and operation of responsible enterprises and the supply of important raw and auxiliary materials in a stable and orderly manner. We should know that ultra-low emissions are encouragement oriented and leading to the advanced, while qualified emissions are legal responsibilities. There are differences between the two. For steel enterprises that have completed ultra-low emissions transformation, we should increase policy support to encourage advanced construction of a fair competition, healthy and orderly development environment.

The iron and steel profession should select mature and applicable environmental protection transformation skills according to the plant conditions, select reasonable transformation skill routes, and try to select units with performance experience in key emission reduction skill projects such as efficient dust removal, hierarchical desulfurization, activated carbon desulfurization and denitrification, SCR denitrification, etc., and also hope that the country can give enterprises in the transformation process sufficient time to constantly improve when they can safely meet the ultra-low emission requirements. It is suggested that the Ministry of Ecology and Environment of the People's Republic of China should work with the Ministry of Science and Technology, the National Development and Reform Commission and the Ministry of Industry and Information Technology to jointly establish a special project to develop ultra-low emission skills, support steel enterprises to further strengthen cooperation with universities, scientific research institutions, environmental protection engineering skills companies, etc., to develop ultra-low emission skills of sulfur dioxide and nitrogen oxides in flue gas such as hot blast furnaces and heating furnaces, and to develop skills in the treatment and utilization of waste liquid and ash from fine desulfurization and denitrification of blast furnace gas, High efficiency electrostatic bag dedusting and bag disposal of filter materials and other technical weaknesses were tackled.

Iron and steel enterprises should also be bold to use them creatively, increase investment, speed up the cracking of environmental protection problems in development with higher standards, make relevant ultra-low emission methods and requirements have solid pollution control and management skills to ensure stability and qualification, become ultra-low emission skills that can withstand previous tests, and ensure the high-quality development of the iron and steel industry.
