摘　　要：研究了存在回用、再生回用和再生循环的多杂质水网络,修正了水网络同步设计的超结构模型。该模型可以合理表征有效物质回收、杂质间存在反应以及废物处理等多种技术。采用通用代数建模系统(GAMS)编程,求解了多杂质水网络混合整数非线性规划(MINLP)问题。同步设计的脱硫实例优化方案与文献值相比,年度总费用可降低8%以上。求解石油化工中常见的含碳稀氨水回收例题,优化设计结果可以满足各组分单独回收要求,避免杂质间反应,提高了水的重复利用率。The multi-contaminant integrated water network containing water reuse, regeneration reuse and regeneration recycling was studied, and the superstructure model for the synchronous design of the water network was improved. This model can reasonably characterize the valuable material recovery, the reactions between multi-contaminants and the waste treatment. The optimization problem is formulated as a mixed integer non-linear programming （MINLP） problem and solved using synchronous design program supported by general algebraic modeling system （GAMS）. Compared with the data in literature, the total annualized cost of a desulphurization case optimized by the synchronous design can be reduced by over 8%. When this method is used to solve the problem of ammonia recycle, CO2 concentrating and water recycle from dilute ammonia water, which is familiar in petrochemical industry, the optimized design can meet the requirements of separated recovering each component, preventing the reactions between contaminants, and increasing water reuse rate.
