关于多污染因子用水网络的建模与优化方法

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%。

The modeling and optimization of water-using network design with multiple contaminants

Up to now,the researches on water-using network synthesis,and the researches on large-scale water-using network synthesis with multiple contaminants have not gone far.So the designing of the networks are always not practicable.To solve this problem,model of water reusing network was set up by contaminant mass-exchange model of water using process.The minimization of fresh water requirement was resolved by the method of matching using-water network design.The water currents were assorted into fresh,low-conta...
