A new method is putforward and four basic rules are provided. The key point of themethod is that global optimality is obtained by guaranteeing theoptimality of each step taken in the design. Costs per unit mass ofremoved contaminant are used as a scale to choose the nextcombination of an effluent stream and a treatment process. Theremaining problem is updated after each choice. As for multiplecontaminants, a two-stage method is adopted.展开更多
