Rainwater Utilization Technology Integration Packages In Olympic Areas

With the increase in the level of urbanization and rapid economic development,in particular,because of modern society and urbanization have brought about shortage of water resources and ecological aspects of environmental degradation.Rainwater utilization technology had gradually be taken seriously and had impro-ved a lot.Urban rainwater utilization in China is still at an early stage,rainwater harvesting in cities with a saving of water resources,flood mitigation,groundwater recharge,control of runoff pollution and improving the urban ecological environment and so on.Beijing area's water resources mainly come from natural precipitation,and the annual rainfall concentrated in the 6?9 month,taking into account the completion of the Olympic central area will form a larger surface hardening,The Olympic Games being held again in concentrated rainfall in the rainy season,So,for the actual situation of the Olympic field region,established a rainwater utilization system,rainwater utilization of existing technology and components of rainwater utilization of new R&D integratied of application,rainwater utilization of resources to fully reflect the concept of complete sets of technology integration,order to reduce the rain outside the emissions,conserving local water sources.The subject of theoretical method is the main line,to guide the practice for the purpose,use of experimental research,theoretical analysis and demonstration projects for construction of a combination of methods,central area of the Olympic Park for the amount of rainwater resources were calculated by analysis and techno-economic analysis,and an analysis of rainwater utilization system for rainwater water quality.Concluded that:technical Is feasible and economically reasonable,not only has significant water-saving benefits also has significant social and environmental benefits,to alleviate water shortages in northern cities in China,improving the urban ecological environment of great significance and good promotion prospects.
