摘要
引入“资源效率”的概念 ,分别定义了钢铁工业水的循环率μ和水的资源效率γ,并以长江流域 2 2个钢铁企业的用水指标为例讨论了γ和μ之间的关系。根据水资源效率和工艺用水量两个指标 ,将钢铁企业划分成了 A、B、C和 D四类 ,在此基础上 ,分别讨论了这四类企业节水工作的重点和应该采取的路线。
The concept of resource efficiency is introduced.The water recycling rate μ and water resource efficiency γ for steel industry are defined,respectively.Taking 22 steel companies along the Yangtze River as examples,the relation between γ and μ is discussed.With this two indexes,i.e. water resource efficiency and process water consumption,the steel companies are assorted into A,B,C and D categories.Based on that,the major tasks and methods of water-saving for the above mentioned four types companies are discussed.
