【摘要】 中国是严重缺水的国家,水资源供需矛盾十分突出。雨水是地下水的最重要补给源,也是解决水资源供需矛盾的重要途径之一。本研究中,通过借鉴美国雨水涵养与初雨水净化的成熟经验,设计了中国雨水涵养利用与初雨水净化系统,对屋面、绿地、道路、硬覆盖的排水与雨水涵养以及涵养水的利用、初雨水的净化等进行了研究。该系统在涵养雨水的同时,解决了初雨水净化的问题,与非涵养的普通雨水排水系统相比,管道长度短,管径小,节省了系统造价,是中国雨水利用的创新体系。更多还原

【Abstract】 Storm water as special source is related to the national economy and the people’s livelihood.Rational use of water is one of important ways for resolving the contradiction between supply and demand of water.In this paper,storm water conservation and the crude storm water purification in the United States of America was introduced and a storm water conserving and using system was studied and developed.The flow change was analyzed after the water was conserved.更多还原
