提出并建立园区层面全局用水网络的超结构模型,运用数学规划法,以用水成本最小化为目标,确定新鲜水用量及其对应的全局用水网络结构。以新鲜水价格变化为驱动力,提出新鲜水价格区间与其对应的用水网络综合的关系。以某园区为实例,当水价分别在0～0.7、0.7～2.58和大于2.58美元/10~3gal区间时,对应的新鲜用量分别为1829×10~3gal/d、529×10~3gal/d和0 gal/d。随着新鲜水价格的增加,新鲜水的用量会逐渐减少,相应的再生水处理单元数会逐渐增加。
The superstructure model of the global water network at the park level is proposed and established. Using the mathematical programming method, the minimum water cost is taken as the goal, and the fresh water consumption and its corresponding global water network structure are determined. Driven by the change of the price of fresh water, the relationship between the price range of fresh water and the corresponding water network is proposed. Taking a park as an example, the corresponding fresh water consumption was 1829 × 10 ~ 3 gal / d and 529 × 10 ~ 3 gal / d when the price of water was 0 ~ 0.7, 0.7 ~ 2.58 and greater than 2.58 ~ 10 ~ 3gal respectively 0 gal / d. As the price of fresh water increases, the amount of fresh water will gradually decrease, and the corresponding number of reclaimed water treatment units will gradually increase.
