摘要： 把钢铁企业的各用水环节和生产过程作为一个系统来研究,将物质流分析(substance flowanalysis,SFA)的跟踪模型借用到钢铁企业的用水网络优化研究中,构建钢铁企业的用水网络模型及其评价指标体系.以我国某大型钢铁集团为例,构建其用水网络模型,并识别出其用水系统存在的问题,依此对其优化和评价分析.结果显示:节水潜力大的环节主要体现在焦化、连铸和轧钢工序;评价指标中水环境效率提高潜力大,优化措施的节水成效显著.将物质流的跟踪模型理论和方法应用到钢铁企业用水网络的优化分析,可为其提供理论指导.

Abstract: Integrating all the water-consumption processes and the whole production process of an iron and steel complex into a water-consumption network system, then the model of the system was developed with its evaluation index system given via the following-observing model of SFA (substance flow analysis). An iron and steel complex in China was taken as an example to which a water-consumption network model was developed to find out the problems in water-consumption system, thus analyzing its optimization and evaluation. The results revealed that the system has even more water-saving potential in such processes as coking, continuous casting and rolling with a high potentiality of water-environment efficiency as an evaluation index and remarkable water-saving achievement due to optimization. All of these showed that the SFA following-observing model is available to theoretically optimize the water-consumption network in an iron and steel complex.
