雨水资源利用的设计构想

水资源短缺是全世界面临的问题，各国都采取相应的措施，如提倡节约用水、立法立规、提高水资源利用率等。文章在现有研究成果基础上，设计了适用于中国南方地区民宅的雨水收集利用系统方案。该系统采取屋顶集水和土地渗透集水两种方法收集雨水，利用雨水自重与水泵相结合的方式提供动力，将储存的雨水用于灌溉、洗车、冲厕等，并通过与集水装置相结合的屋顶绿化对住宅局部气温和空气湿度进行调节，提高住房环境的舒适度。

Exploration of Technologies on Using Rainfall Resources

Water shortage is a worldwide problem. Therefore,a series of appropriate actions have been come up with by many countries,such as water saving,making laws and regulations,and increasing water efficiency. In this paper,it suggested a design of using rainfall resource based on the previous studies, which is suitable for the rainwater harvesting and utilization of southern region in China. In this design, rainwater is harvested mainly via roof and land permeable catchment. Additionally,gravity and water pumps are utilized to provide motion for rainwater utilization system,such as irrigation,washing,flushing. Moreover,the way of combination between roof catchment device and roof residential greening can adjust and optimize local temperature and humidity of buildings so as to enhance the comfort of residences.
