Campus Residential Water Reuse Simulation And Prediction

In recent years, China’s continued to develop education, universities areconstantly increasing enrollment of students in everywhere, so the number of studentsincreases every year, the size of the university campus is constantly expanding, andwith the constant campus construction, expansion and construction changes, thedemand for water will grow, so the water reuse systems will used in the campuscommunity is very feasible. For the university campus, the main sewage includingtoilet flushing water, toilet water, laundry water, bath water, canteen wastewater. Itsdaily water use is relatively stable, and the place is relatively concentrated water,wastewater composition is simple, with organic-based, non-existent water fluctuations,and fluctuate with the seasons is not great. If the university campus communitywastewater can be effectively reused, not only can greatly reduce the emission ofpollutants, but also to alleviate the shortage of urban water pressure will producesignificant economic, environmental, educational and social benefits, for theimplementation of the national energy policy, the construction ofenvironment-friendly and resource-saving society has a good practical significance.According to the university campus with the drainage characteristics, XinjiangUniversity for the study has a theoretical basis for the system dynamics, use systemdynamics software Vensim PLE, mainly from the following aspects to carry outresearch:(1) Research methods for system dynamics modeling process, and thedevelopment of software classification system dynamics.(2) Quantitative analysis of the relationship between the water and theinfluencing factors of Xinjiang University among them, the use of system dynamicsfor system analysis, water reuse SD system dynamics model to predict the amount ofwater in the next18years the school water and its dynamics changes, analyze themain factors influencing water reuse. (3) According to the actual situation, by changing the values of the decisionvariables set up different scenarios for predictive analysis. Predict water reuse wateranalyzes to determine the direction of water reuse universities.(4) Based on the results of its predictive analysis of economic, environmental,educational and social benefits of water reuse system produces analyze and study thefeasibility of water reuse campus use.
