Abstract：In the production process of iron and steel enterprises，a large amount of dust and sludge with iron element as the main component is produced. Iron and steel dust sludge is an important part of solid waste in iron and steel industry. It contains valuable elements such as iron，carbon，zinc，potassium，sodium and so on. If it is stacked or discharged directly，it will inevitably cause environmental pollution. And the valuable elements in the Iron and steel dust sludge are not used effectively. Iron and steel enterprises should choose appropriate methods and equipment based on understanding the composition characteristics of different types of dust sludge，defining the final purpose and effect of the recycling and utilization of dust sludge. The utilization technology and method of iron and steel dust sludge are analyzed，and the main direction of dust sludge treatment in the future is put forward，which is the combination of fire and wet process.
