Abstract:

As a collection of multiple/various production enterprises, an industrial park is able to produce more opportunities for the cooperative utilization of resources. In this context, specific resource allocation strategies are desired for parks because of their characteristics that different from a single plant. To solve the water allocation problem of parks and also consider the practical production requirements, this study presents a synthesis method considering intra-plant pre-treatment operation in individual plant, which means the inter-plant and intra-plant regenerators are both set and selected during synthesis. The superstructure and the mathematical model are thus established and formulated with the target of minimum fresh water consumption. Finally, an example is illustrated to demonstrate the capability of the method.

Key words: water network, industrial park, indirect reuse, pre-treatment, regeneration, optimization, integration

摘要：

工业园区是集合多个/多种类生产企业的综合体,建立工业园区使资源在企业间的协同利用成为可能。然而由于园区存在诸多区别于单厂/单个企业的特点,所以需要提出有针对性的方法以实现资源在园区内的合理分配。针对工业园区的用水问题,同时结合实际生产需要,提出了一种考虑厂内预处理操作的园区水网络综合方法。该方法在设置厂际间中央再生器的同时,为满足其操作浓度约束,重点考察了各厂内预处理器的设置和选择问题。通过建立用水网络超结构和数学模型,最终以新鲜水用量最小为目标,实现了再生器的选择、再生负荷的优化和园区总网络的设计。
