With an increasing shortage of water resources

more rigid regulations regarding waste water discharge

water saving and discharge reduction have become more and more valued by industries. However

the traditional water utilization networks only regard impurity concentration as the restricting factor for controlling material reuse and overlook the effect of stream's characteristic or function on its reuse

thus unable to reflect the actual industrial production requirement. Therefore

it is of great significance to look into the multiple-property integration of water utilization networks. In this paper

a method is proposed where the super structure model of multiple-property water utilization considering the environment problems is presented as a basis

on which a process is added to reuse part of streams in the treated water stream characteristic process for the sinks. This method takes the minimum annual cost as the target function and builds the mixed integer non-linear programming mathematical model with the consideration of environment

the direct reuse of stream in the process and reuse of stream from treated water. The model is then evaluated

whose result reveals that this method reduces not only the annual total cost but also the use of fresh water and waste water discharge

validating the efficacy and superiority of the proposed method.
