钢铁企业生态效率分析

从工业生态学的角度定义了“产品”的概念,给出了分析钢铁企业生态效率的三个指标资源效率、能源效率和环境效率.以某钢铁企业为例,采用工业代谢分析方法,建立了企业物料结算平衡表,理清了输入、输出企业的资源、能源、产品、废品和污染物的种类及数量,并对该企业生态效率的现状进行了分析比较.在此基础上,讨论了企业间相互利用废品和污染物的共生关系对企业资源效率、能源效率和环境效率的影响.结果表明,在企业间形成相互利用废品和污染物的共生关系,是解决企业资源、能源和环境问题的重要方法和途径.

Analysis of Eco-Efficiency of Steel Industry

Defining the "product" from the angle of industrial ecology,the three indices of eco-efficiency are given,i.e.,resources efficiency,energy efficiency and environment efficiency,to analyze the eco-efficiency of steel industry.Taking the data of a steel enterprise as example,an input/output balance sheet was worked out by way of industrial metabolism to make sure of the sorts and amounts of resources,energy,products,wastes and pollutants and analyze the eco-efficiency of the steel enterprise.Discusses the influence of symbiotic relationship among the wastes/pollutants utilized mutually by different enterprises on the three efficiencies mentioned above.It was found that the formation of such a symbiotic relationship is an important way to solve the increasingly serious problems of resources,energy and environment in China's steel industry.
