【摘要】：为了快速有效地进行具有中间水道的用水网络设计,提出了基于水夹点分析的用水网络设计方法。水夹点分析基于对用水过程中使用新鲜水或回用水的指导,获得初始中间水道浓度估计值并给出中间水道中水分配的基本规则。首先根据水夹点浓度确定中间水道杂质浓度,并对用水单元进行分组,安排用水单元在用水网络中的位置,然后优化中间水道水流量,确定最优用水网络结构。水夹点分析提供具有中间水道初始用水网络结构,降低数学优化求解的规模和难度,所提夹点设计方法简捷易行。2个实例的计算结果表明,所提出的方法比简单的夹点分析和节水因子方法可分别节水2.56%和7.58%。
[Abstract]:In order to design water network with intermediate waterway quickly and effectively, a water network design method based on water pinch analysis is put forward. Water pinch analysis is based on the guidance of using fresh water or reusing water in the process of water use. The initial intermediate watercourse concentration estimation is obtained and the basic rules for water distribution in the intermediate watercourse are given. Firstly, the impurity concentration of the intermediate watercourse is determined according to the water pinch concentration, and the water unit is grouped to arrange the location of the water unit in the water use network. Then the water flow of the intermediate channel is optimized and the optimal water network structure is determined. The water pinch analysis provides the initial water network structure of the intermediate watercourse, which reduces the scale and difficulty of the mathematical optimization solution. The calculation results of two examples show that the proposed method can save water 2.56% and 7.58, respectively, compared with the simple pinch analysis and water-saving factor method.
