Abstract：Based on the environmental protection, the waste acid recycling and the preparation and application of iron oxide powder after the acid washing of hot- rolled steel in the acid regeneration process in iron and steel enterprise are introduced. By optimizing and innovating the technology and constantly improving the product quality and usage, the customer requirements for different quality of iron oxide powder are satisfied by constantly, the acid regeneration and first- grade product rate of ferric oxide powder are effectively enhanced, and the environmental impact of by- products from iron and steel enterprises is reduced. In the modern enterprise production process, improving the efficiency of solid waste resource utilization, progressively realizing the resource utilization, reducing the environmental pollution, decreasing the operating costs, and forming the green recycling and sustainable development mechanism have become the theme of the times development as well as the social responsibility of the enterprise.
