地球上的资源是有限的,随着人类消耗资源数量的增加,资源的缺乏日趋严重。因此节能降耗,资源综合利用已是世界范围各国共同的课题。人类生存的地球环境需要保护也已被世界各国政府公认。资源短缺和环境污染是制约钢铁工业发展的重要因素之一,为了发展循环经济,实现钢铁工业可持续发展,必须大力节约一次资源,合理开发利用二次资源,优化生产流程,减少污染物的发生量和排放量并开发应用高新技术。
The resources on Earth are limited. As the amount of human resources consumed increases, the lack of resources becomes more and more serious. Therefore, energy saving, comprehensive utilization of resources has been a common issue in all countries in the world. The global environment in which human beings need protection has also been recognized by governments around the world. The shortage of resources and environmental pollution are one of the important factors that restrict the development of the steel industry. In order to develop a recycling economy and achieve the sustainable development of the steel industry, we must save resources once, develop and utilize secondary resources reasonably, optimize the production process and reduce the occurrence of pollutants Volume and emissions and the development and application of high technology.
