People’s Daily Online, Shijiazhuang, January 29 (Zhao Mingyan) The city is getting farther and farther, and lush bushes begin to appear along the street, and the image wall of “Lucid waters and lush mountains are invaluable assets” comes into view. This is Delong Iron and Steel Group, located in Xindu District, Xingtai City, Hebei Province, next to the eastern foot of the Taihang Mountains, covering an area of 1,800 mu.
“National AAAA-level tourist attraction”, the first batch of “green factories”, the first environmental protection “A-level enterprise” of a domestic private steel enterprise… Now there is never a shortage of group photos in the factory area of Delong Iron and Steel Group. But in the past, the most common phrase that workers said was “turning your head up and looking ashy, and raising your feet full of dirt.”
“The issue of environmental protection has risen to the level of the life and death of an enterprise.” In 2014, Ding Liguo, chairman of Delong Iron and Steel Group, stood in the factory and looked around, silently making a major decision in his heart.
Then, in accordance with European standards, the environmental protection requirements were comprehensively raised, and the environmental protection management formulated monthly and quarterly assessments, and went to the enterprises that have done it to conduct benchmarking exchanges. Buildings, pipes, and facilities were painted, and waste sculptures were used to beautify… Long Iron and Steel Group began to embark on a unique road of transformation and development of steel enterprises.

In June 2017, a machining workshop was suddenly dismantled in the factory area, and the workers were talking, “This is to build a bigger one, buy more machine tools, and increase the production of parts.” What came to my mind was that, 4 months later, a comprehensive museum with multiple functions of display, popular science education and reception rose up on the ground, which contained many exhibits that witnessed the development of Delonghi.
“Why do you invest so much in environmental protection?” Ding Liguo has been asked many times this question.
“Green development has become an inevitable trend for the future development of iron and steel enterprises. Whoever takes the initiative will gain the initiative for sustainable development.” Ding Liguo said that Delong has gradually established a circular economy ecosystem, enabling circular economy and energy conservation and emission reduction. To become a new development mode, a new profit growth point and competitiveness, Delonghi should be built into a model of circular economy and energy saving and emission reduction.
As a result, Delong Iron and Steel Group has appeared in many “first” titles.
The first closed blast furnace casting yard in a domestic iron and steel enterprise; the first to use intelligent environmental protection fog piles, real-time monitoring of PM2.5, PM10, and automatic spray adjustment to improve air quality; the first to use a car washing machine… As long as it is compatible with environmental protection Delong will ignore the gains and losses and try boldly. This kind of daring spirit affects more and more “Delong people”.
It is understood that since 2014, Delong Steel Group has invested a total of 3.3 billion yuan in environmental protection funds, with an annual per capita environmental protection investment of 130,000 yuan, and the environmental protection operating cost per ton of steel has reached about 300 yuan. Through continuous in-depth environmental governance, Delong Steel Group achieved ultra-low emissions, with an average daily emissions of 1,232kg in 2021, 23% lower than 2020 and 62% lower than 2019. At present, the emission of particulate matter per ton of steel is 0.12kg, the emission of sulfur dioxide per ton of steel is 0.03kg, and the emission of nitrogen oxides per ton of steel is 0.15kg, reaching the international advanced level.

“On the basis of the original environmental protection system, a new bag filter, a new white ash digestion dust collector, a new SCR flue gas denitrification system, a new steel-making fully enclosed stock yard and a micro-powder workshop are newly built. Wait.” Huo Zenghe, Minister of Environmental Protection of Delong Iron and Steel Group, said firmly, “On the basis of fully helping Xingtai ‘return ten’, we have taken the initiative to add many projects. We are serious about environmental protection.”
Not only that, Delong Iron and Steel Group has innovated the management and control methods, and the environmental management has moved from “human sea tactics” to technological and lean. Establish an intelligent management and control platform for the environmental protection command center, which integrates organized discharge, unorganized discharge and on-site management and control to realize intelligent management and control of environmental protection; integrate all operating parameters of each pollution control facility, CEMS online monitoring data, and reflect production load and equipment. The main production process parameters of start and stop are connected to the platform for centralized management…

In 2020, it was rated as an ecological and environmental education base in Hebei Province; in 2021, it passed the evaluation of Hebei Province’s environmental self-discipline system and was included in the positive list of environmental law enforcement… Delong Iron and Steel Group continues to prove its choice with new achievements. “I can proudly say that Delong has reached the world’s first-class level of iron and steel enterprises in terms of environmental protection and has become a nationally recognized benchmark.” Huo Zenghe’s face burst into a smile.
From the desolate ruins to the verdant factory buildings, from the bleak social image to the prosperity of the scenic spot, from the management of a mess to the rising technical quality, Delong has never stopped its journey towards “green”. pace. Today, walking in the factory area along the cherry blossom avenue with unique Delonghi characteristics, you can feel the new vitality and vitality everywhere.
