Water Recycling Reuse Of Simulation And Prediction Of SD Model

Today in the severe shortage of water resources, water reuse the solution to urban water shortage and water pollution, an important and effective way to much attention. Hohhot in northern arid and semi arid areas, rainfall is very uneven spatial and temporal distribution, and water resources is a serious contradiction between supply and demand. As the groundwater over-exploitation and serious pollution, water shortage problem is serious. Face this problem, water reuse is imperative.The paper on the actual situation of Inner Mongolia Agricultural University, analysis of water collected over the years a variety of school situations, using system dynamics software, the school situation of water reuse in recent prediction analysis, to achieve the purpose of saving water. This article from the following areas:1. Detailed analysis and comparison of the decentralized water reuse and centralized water reuse advantages and disadvantages, to determine the selection of today's distributed back to the city with water as the main form of reuse. History on the development of water made a detailed presentation on the selection of water sources, treatment process selection and so on have done a detailed analysis, given the typical water treatment process in the water cost of water system models and economies of scale model.2. Colleges and universities in the water reuse feasibility analysis of the college water reuse advantages. The selection of the university according to the actual source of water and water treatment process. Surveys in Inner Mongolia Agricultural use of water by the school for many years to understand the school's expansion and future planning to change the situation, analyze the various factors affecting the school water, the establishment of system dynamics model. Repeated on the first test and improve the model to make it more perfect.3. SD using established school predicted the use of water the next two decades. First of all, the last time through the prediction and the actual quantity of water, compared the proposed model is correct. And through sensitivity analysis, sensitivity analysis to determine the impact on the school water sensitive element. By forecasting analysis to determine the construction in Inner Mongolia Agricultural University, water reuse project time to the schools for effective water reuse strategies, create a campus, thus saving water and improving water environment as a contribution.
