Abstract:

A new approach of water utilization networks design based on water quality analysis and mathematical programming was presented.According to those limiting operation data given in the literatures, the quality of different water samples was calculated respectively, and their priority was specified in sequence.The best quality water was preference as water provider, provided the quantity can meet the demand, the others were omitted from providing,and then the superstructure was simplified significantly.Finally, a NLP program in GAMS language was used to determine the minimum freshwater flow rate, the reuse water flow rate and wastewater flow rate.Applied in two examples, the present approach was proved to be feasible and desirable.

摘要：

在多杂质用水系统中，各操作出水水质会以不同杂质为主要因素，难以直接比较水质优劣，本文提出了水质分析与数学规划法相结合的用水网络最优化设计方法，对进出口水的极限数据进行分析得出水质状况并对它们按优劣进行排序，优先将排在前面的、节水效果好的操作作为供水源，在水量足够的情况下，对后面的操作不予考虑，以此来简化用水网络超结构模型，然后利用GAMS软件对经过简化后的超结构进行非线性规划并求解，通过两个例子的分析，证明了本方法的有效性。
