基于能值理论分析方法的工业供水效益研究

Based-on Emergy Theory Analysis for the Benefit of Industrial Water Supply

应用能值理论及其统一的衡量标准,将决定工业供水效益的主要指标——供水投入与工业生产系统产出转化为同一的量纲,克服了传统方法计算工业供水效益时无法衡量自然环境对工业生产过程影响的缺陷,定义工业供水总能值和生产投入总能值的比值为工业供水效益分摊系数,建立并分析研究影响工业供水效益的各项指标,为工业供水效益的提高提出建议。

This article applies energy theory and its uniform criterion and translates the main index determining the benefit of industrial water supply-input water and industrial output to same dimension.It overcomes the defect in traditional method employed to compute benefit of industrial water supply which is unable to judge the impact of nature environment on industrial production.Benefit sharing coefficient is defined as the ratio of industrial water supply emergy to production input emergy.All indexes affecting benefit of industrial water supply are analyzed to provide specific methods to enhance benefit of water supply.
