摘要
用系统动力学方法研究了城市污水回用系统.首先分析了影响城市污水回用系统的诸多因素以及它们之间的相互关系,探讨了污水再生回用系统行为和结构的特点,确定了系统中因素之间的定量关系,建立了城市污水回用系统动力学(SD)模型,并介绍了模型的检验方法.同时给出了SD模型的具体应用实例,对西北地区的某一城市的污水回用进行了预测和分析,提出了符合该城市发展的污水回用方案.
The system of wastewater reclamation and reuse was discussed with the System Dynamics. The many factors effecting on water reuse, relationships of these factors and the characteristics of this system structure were analyzed. Thus, the SD model of wastewater reclamation and reuse was built in this paper. The sensitivity analysis of the SD model was presented. Meanwhile, the water reuse volume of the city in northwestern area were forecasted by means of the SD model, the better plan of the city wastewater reuse was put forward and the scientific decision was supplied for decision--maker.
