Abstract The environment is an objective material and biological system that the mankind depends on for existence, and the iron and steel enterprises have already aroused the attention from different social fields as one of the important environmental pollution sources. This article introduces the iron and steel enterprise waste gas origin and the cleaning technology survey, including the mist and dust processing technology and desulphurization technology in the waste gas treatment. By comparing the domestic and international emission treatment technology, to it points out a specific direction for enterprises to introduce and promote the new environmental technology.
Key words steel industry, waste gas, cleaning technology
