具有中间水道的多杂质用水网络简化设计方法

A simple design method for water network with multi-contaminant internal water mains

与常规水网络相比,具有中间水道的水网络更有利于运行和控制。浓度势是作者最近提出的解决多杂质用水网络设计的新概念。在浓度势概念基础上提出了一种具有中间水道的多杂质用水网络设计新方法。该方法采用浓度势方法设计出初始水网络,并在此基础上初步确定各中间水道的结构及水量,然后根据浓度势从小到大的顺序依次由中间水道满足各用水过程,而各级中间水道的最终水量以能满足各级水阱需求来确定。该方法只需简单计算即可完成具有两级中间水道的水网络设计。对文献实例求解结果表明,所得结果与由数学规划法得出的结果接近。

The water-using networks with internal water mains have the advantages of easy operation and control compared to the conventional ones.The concentration potential is a new concept proposed recently.In this paper,a design method for water-using networks with internal water mains is presented.The new method designs an initial water-using network by using the concentration potential method first.The structure and water quantity of the internal water mains are determined based on the initial network obtained.Each demand is satisfied by an internal water main according to the ascending order of the concentration potentials of the demands.The water quantities of the internal water mains are determined by satisfying the corresponding water demand.This method can design a water-using network with two internal water mains by simple calculation.The results obtained by using the method proposed for a few case studies in the literature are close to those obtained by the mathematical programming method.
