Abstract:The increasingly serious haze weather makes the national environmental protection department pay more attention to the problem of air pollution, and the atmospheric pollutants that cause haze weather are becoming more and more known to us and classified. In China, sulfur dioxide and nitrogen oxides have entered the end stage of governance. And the governance of dioxins is still in its infancy. Dioxins are one of the most toxic compounds in unconscious by-products found in scientific research. The toxicity of dioxins to humans is mainly reflected in the irreversibility of damage. The formation mechanism and degradation methods of dioxins, as well as the current research status in this field are introduced. At the same time, combined with the production status of key processes such as sintering and electric furnace steelmaking in the iron and steel industry, the mechanism of dioxins produced in different processes was founded, and different treatment degradation methods for different mechanisms were proposed.
