随着工业化进程的加快,自然资源的不合理利用和污染排放问题日益突出,大气污染、全球气候变暖、森林锐减、土地沙化、水体污染,人们赖以生存的生态环境遭到严重的破坏。而在这些破坏生态环境的污染物中有70%来源于制造业,钢铁行业又属制造业中的高排放、高污染大户,因此,钢铁工业要保持持续的发展,就必须大力发展循环经济,用循环经济的理
With the acceleration of the process of industrialization, the problems of unreasonable utilization of natural resources and pollution discharge have become increasingly prominent. Air pollution, global warming, sharp decline in forests, desertification of land and water pollution have caused serious damage to the ecological environment upon which people depend . 70% of these pollutants that damage the ecological environment come from the manufacturing industry, and the steel industry belongs to the high-emission and high-polluting industries in the manufacturing industry. Therefore, in order to maintain the sustainable development, the steel industry must vigorously develop the circular economy, With the principle of circular economy
