当前对大规模多污染因子水网络的研究尚未深入,故用水网络设计多缺乏实际意义。今利用用水过程污染物传质模型构造水回用网络模型,以配合法求解多污染因子情况下最小新鲜水用量的实现方法,每1用水过程入水以新鲜水、低污染回用水和高污染回用水配合获得,使各过程关键污染因子为依据的进水流量比尽可能趋近1。各过程按出口极限浓度之积由低到高依次运算。该方法以过程为运算单元,避免软件求解,不受用水网络规模的限制,此方法在用水网络优化技术方面有所创新。最后通过实例说明该方法有效,以其指导某石化企业,节水效率达到17.81%。 At present, the research on large-scale and multi-factor water networks is not yet in-depth, so the design of water networks lacks practical significance. In this paper, the water reuse network model is constructed by using the mass transfer model of pollutants in water process to realize the minimum fresh water consumption in the case of multiple pollution factors. Each time the water is used, fresh water, low-pollution water and high pollution back Water with the acquisition, so that the process of key pollution factors based on the inflow ratio as close as possible 1. The process of export by the concentration of the ultimate concentration of low to high order operation. The method takes the process as the arithmetic unit, avoids software solving, and is not limited by the size of the water network. This method is innovative in the water network optimization technology. Finally, an example is given to show that the method is effective and guided by a petrochemical company, saving water efficiency of 17.81%.
