中文摘要：
针对城市区域用水网络的节水优化问题，建立了半连续间歇用水网络的优化数学模型．以某大学校园的用水网络为实例，通过实验获得了模型中各用水过程的进出口浓度极限数据，并估算了各用水过程的污染物负荷．采用LINGO软件求解了该数学模型，获得了可节约新鲜水约12％的水回用网络．研究表明，所提出的半连续间歇用水网络模型反映了市政区域用水的主要特征，可用于优化城市区域的水回用网络．
英文摘要：
In respect of optimization on water conservation problem of water-using network in municipal area, a mathematic model of water-using network with half-continuous batch processes was proposed. A water-using network in a campus served as a ease study. The limit data of inlet and outlet concentrations of water-using processes were obtained through experiments. The mass loads of contaminants in the processes were estimated. An optimized water-using network that can save about 12% fresh water was obtained by solving the mathematical model problem by a commercial software LINGO. The results show that the proposed mathematic model reflects the primary features of the water-using in the municipal area, and can be utilized in the optimization of the water-using network in municipal area.
