| 提出了水夹点分析和数学规划法相结合的废水处理网络最优设计法．基于对过程用水的理解，通过水夹点分析得出废水处理网络设计的基本规则．在此基础上建立了废水混合、合并、处理和排放各种可能匹配方案的废水处理网络超结构及其NLP模型．既避免了用水夹点综合设计废水处理网络存在回路，又在一定程度上防止了超结构规模过大、NLP维数太高、求解困难．采用通用代数建模系统 GAMS 得到废水处理网络最优设计方案．文献中的应用实例表明，所提方法可充分发挥水夹点分析处理结构的简洁实用性和超结构NLP寻求最佳方案的优点． |
| 英文摘要: |
| An approach of optimal wastewater treatment networks design by the combination of water pinch analysis and mathematical programming is presented. Water pinch analysis is used to determine the elementary rules for wastewater treatment networks design based on the understanding for wastewater treatment process. Then, a superstructure of wastewater treatment networks and an improved nonlinear programming (NLP) model are built which involves only feasible and better retrofit options considering mixing, treatment and discharge of wastewater. The approach overcomes the defect that water pinch analysis designs the wastewater treatment network with loop and prevents the case that the superstructure is so large that it is difficult to solve it. At last, the general algebraic modeling system (GAMS) is adopted to attain the optimal scheme of wastewater treatment networks. Case study illustrates that the combined method can determine the treatment structure concisely and practically by water pinch analysis and reach the global optimum of wastewater treatment networks by superstructure NLP. |
