城市雨水利用模型研究

The Utilization Model Research of Urban Rainwater

随着经济的快速发展,城市水资源的供需矛盾日益突出,雨水作为一种洁净、新型、储量丰富的资源越来越得到人们的重视和使用。详尽而系统地阐述了雨水资源的多元化应用,结果表明:屋面雨水经过初期弃流收集以后可以作为城市的杂水使用;绿地雨水主要通过设置下凹式绿地和设置径流小沟、渗水管和集水井等使雨水就地入渗补给地下水;非机动车道和人行道的雨水主要通过透水面进行充分下渗回归地下水;城市多余雨水也可以用于农业灌溉。通过研究可以使雨水利用更加系统化和多样化,为不同区域的城市雨水利用提供依据。

With the rapid development of economy,the contradiction between supply and demand of urban water resources is increasingly prominent. Rainwater as a kind of clean,new and abundant resource was more and more get people＇s attention and application. This paper expounds the diversity of rainwater resources detailedly. The results showed that roof runoff after early abandon flow can be used as the miscellaneous water; green space water can be used to local infiltration recharge and supply the groundwater by setting the recessed groove,the runoff water penetration tube and the collecting well; water in non-motor vehicle lanes and sidewalks mainly collected through the surface to fully back infiltration of groundwater; city rainwater surplus can also be used for agricultural irrigation. This study can be used to study the rainwater more systematic and diversified and provide the basis for rainwater utilization of different parts of urban.
