The green development of the iron and steel industry must rely on the renewal of environmental protection technologies, in accordance with the basic principles of circular economy, and on a clean production basis, with a focus on the efficient use of resources and energy conservation and emission reduction, and the full realization of low-cost, high-quality steel product manufacturing, energy efficient conversion And timely recycling, large-scale waste disposal - absorption and re-recycling 3 functions, can achieve ecological links with other industries and neighboring society, thus building a green development model. All this prerequisite is the innovation and development of environmental technology.

When it comes to the future development and innovation of environmental protection technologies, the steel industry should focus on strengthening the following aspects:

The flue gas desulfurization and denitrification technology needs to be further optimized and then fully promoted. At present, the flue gas desulphurization and denitrification technology has become an urgent problem for iron and steel enterprises. In particular, due to the urgent need to upgrade the standards for low-sulfur and low-nitrogen emissions in some localities, the upgrading of desulfurization and denitrification has become an unavoidable issue.

Improve the effective combination of environmental protection and energy conservation and optimize the matching level. In recent years, environmental protection standards have become increasingly stringent, and the load on some processes and equipment used by steel enterprises has increased. Therefore, companies must play an important role in the optimization and dynamic coordination of energy conservation and environmental protection systems in the corporate energy control center.

The whole industry should further implement the green transformation and upgrade, implement the shed and warehouse of raw material plants, coordinate the treatment of multiple pollutants in flue gas, treat the steel slag efficiently and in-depth and comprehensively use, and promote the integrated regeneration and reuse technology of urban waste water and steel industry waste water. To realize the three major functions of steel manufacturing, energy conversion, and waste absorption, and actively explore and successfully implement a harmonious development road with the city.
