Since the "13th Five-Year Plan", our company has closely followed the pace of national green development work, established and practiced the concept that green water and green mountains are golden mountains and silver mountains, adhere to the basic national policy of saving resources and protecting the environment, and treat the ecological environment like life.

Implement environmental protection upgrades, and fully realize "ultra-low pollutant emissions"

Our company has successively invested 2.5 billion to implement more than 100 environmental protection facilities upgrades, and all processes have gradually achieved the goal of "ultra-low pollutant emissions". With coke oven flue gas desulfurization and denitrification, fully enclosed pre-iron raw material system, integrated treatment of sintering machine flue gas denitrification, boiler flue gas desulfurization and denitrification treatment, blast furnace slag flushing water and whitening, steel rolling heating furnace and blast furnace roof equal pressure release CO reduction The application of a large number of industry cutting-edge technologies and independent research engineering technologies, such as the transformation of waste gas discharge, has greatly reduced the discharge of pollutants in the production process. Especially in the iron and steel industry of Tangshan City, it is the first to implement the CO emission reduction transformation of steel rolling heating furnace and blast furnace top pressure release, and explore an effective way for Tangshan City's CO emission reduction work. Compared with the end of the “Twelfth Five-Year Plan” period, the emission reduction of pollutant smoke (dust) is 7038.40 tons, SO2 reduction is 6948.278 tons, NOx reduction is 11084.541 tons, and the transformation from "green manufacturing" to "green manufacturing" is truly realized.

Actively introduce green cutting-edge technologies and participate in national key research and development projects

Our company actively participates in the national key research and development plan of the "Special Research Project on Air Pollution Causes and Control Technology" established by the Ministry of Science and Technology. In the "Multi-process and multi-pollutant collaborative control technology project in the iron and steel industry", our company actively cooperated with the Institute of Process Engineering of the Chinese Academy of Sciences and China Metallurgical Coking (Dalian) Engineering Technology Co., Ltd. to make the "National Sintering Flue Gas Low-Temperature Oxidation Denitrification" "Technology and Demonstration Project", "Coke Oven Flue Gas Multi-pollutant Coordinated Control Technology and Demonstration Project", "Pellet Flue Gas Multi-pollutant Ultra-low Emission Technology and Demonstration Project", "Sulphur and Nitrogen Reduction Based on Optimization of Blast Furnace Charge Structure "Technology and Demonstration Projects" have been implemented successively, providing basic data and research directions for national atmospheric scientific research and exploration, assuming the social responsibilities of large enterprises, and leading the road to energy conservation and emission reduction in the steel industry.

Make full use of information technology to realize the whole process monitoring of pollutants

In 2017, the "Tangshan Iron and Steel Environmental Integrated Management Platform" independently developed by our company was put into use. Since then, the “Tangshan Iron and Steel Environmental Integrated Management Platform” has established an all-round real-time data network of particulate matter, sulfur dioxide, nitrogen oxides, COD, ammonia nitrogen, and CO emitted by fixed pollution sources, and has realized a 24-hour industrial-grade safe and stable integrated monitoring system. On-line monitoring at the end of the environment is converted to monitoring the entire environment.

Continuously strengthen the concept of energy cost and continue to reduce energy consumption

Our company has set up an energy management and control organization, strengthened consistent management, improved operation management and control of operating areas, changed traditional decentralized energy management into centralized and flat management, realized centralized management and control of energy throughout the process, and realized integration of wind, water, electricity, and gas energy Chemical control. In 2018, the comprehensive energy consumption was 532.91 kilograms of standard coal, the remaining energy recovery was 4.48 million tons of standard coal, the water recycling rate was as high as 98.5%, and the ton of steel consumed 2.43 tons of fresh water, which was the leading domestic level.

Innovative urban integration and development to achieve the harmonious coexistence of social enterprises

Our company makes full use of industrial waste heat resources such as blast furnace slag flushing water and equipment cooling water to provide heating and heating for urban residents in winter. In 2018, the heating area reached 5.7 million square meters, which not only reduced the impact of urban coal-fired boilers on the atmospheric environment, but also effectively solved the long-term problem of the shortage of urban heating resources and realized the harmonious coexistence of cities and enterprises.
