节水减排的水系统集成优化研究进展

Research progress on water system integration

水系统集成是节水减排的最有效方法。在过去的二十多年里,水系统集成优化的理论和实践取得了长足的发展。水系统集成的方法分为图示法和数学规划法。本文简单回顾了近年来国内外在这两种方法的研究进展。主要针对废水再生循环和再生回用系统,介绍了采用图示法确定系统目标的方法,以及数学规划法超结构和数学模型的建立。并通过一个实例,说明了方法的应用并比较了废水直接回用/废水再生循环和废水再生回用系统的优化结果。

Water system integration is an efficient way to save freshwater consumption and reduce wastewater discharge. In latest 20 years, both academic research and industrial application of water system integration had been acquired obvious progress. The methods on water system integration include graphical methods and mathematical programming and in this paper, the recent research progress on water system integration for both graphical methods and mathematical programming was briefly reviewed. Focus of the paper was regenerated recycling and regenerated re-use systems using graphical methods, and the superstructures and mathematical models. A case study was used to mark out the application of these methods and compared the results of re-used, regeneration re-used and regeneration recycling of waste water.
