Ecological engineering design of rainfall resource utilization and its application:a case study in Huairou Campus of Graduate School of Chinese Academy of Sciences
雨水回收利用生态工程及其应用——以中国科学院研究生院怀柔新校区为例

To save the water resource in Beijing and reduce the environmental pollution of urban rainfall, the water balance was calculated and the method that recycling the rainfall naturally and reusing it indirectly were advocated, based on the planning in Huairou Campus of Graduate University School of Chinese Academy of Sciences. Then, the flow chart for recycling and reusing rainfall was figured out. And different approaches to collecting rainfall were designed, according to rainfall qualities in different landscape, so as to treat the polluted rainfall uniformly. Ecological Engineering of recycling and reusing the rainfall benefits for saving water resource and supplying groundwater.It can also prevent flood and reduce environmental pollution.
