| 摘 要： | 工业节水及废水减排已成为过程工业持续发展的前提之一。运用目标导向的夹点分析技术对过程用水网络系统进行系统地分析，可确定过程用水、再生水用量和废水排放量的最小目标。以固定再生出口浓度为基准，提出基于累积流量-累积污染质量负荷组合曲线图的夹点分析方法来确定用水网络的最小再生水流量，并给出了详细计算步骤和案例验证。

| Abstract: | Freshwater saving and wastewater reduction plays an important role in industrial sustainable development.To reach such a goal,target-oriented pinch analysis is required to determine the targets of minimum water usage,minimum regeneration water flowrate and wastewater discharge of water-using networks.The aim of this paper is to present a water pinch analysis approach which can help process analysts to target the minimum regeneration water flowrate at a fixed outlet concentration.Based on the diagrams of cum... |
