As the socio-economic development , more and more urban water consumption , but along with the surface water pollution , groundwater overexploitation , urban water supply is less and less , and most cities are facing water shortage predicament . Lower water quality requirements for reclaimed water , can be widely used in life , municipal , industrial, environmental and urban sewage after regeneration treatment . Reclaimed water becoming the city's second water source . However, China's urban regeneration water slowly back to back with the career development rate is very low . The reason , of course , the technical aspects of the problem , that there is no more used as a systematic study of reclaimed water reuse . Therefore , how to improve the reclaimed water reuse rate for reclaimed water reuse with the development of the cause of the actual value . This article is based on the above background, the city reclaimed water reuse system dynamics model was constructed based on at home and abroad for reclaimed water reuse system research . This article First expounded the recycled water reuse system constitutes , mainly from recycled water , renewable water demand subsystem , renewable water supply subsystem and government behavior four part composition , and then analyze the impact of renewable water demand subsystems of the relevant factors , including renewable water reuse form users of reclaimed water reuse and qualitative analysis of the relationship between these factors ; analysis of the impact of relevant factors, including renewable water supply subsystem from the collection of sewage treatment to the entire process of conveying to the regeneration and qualitative analysis of these factors relations , in order to build a reclaimed water reuse system dynamics model provides the basis and premise . Then , on the basis of the above analysis , system dynamics model of reclaimed water reuse and reclaimed water to Beijing to reuse simulation predicted for the case , and put forward policy recommendations . Finally, the content of this research and future research directions , made ??a summary and outlook .
