摘  要：
以小区单独建筑物屋面雨水为研究对象,分析了长沙降雨量变化特性和屋面年径流可利用潜力;设计了屋面雨水集雨系统,即初期雨水弃流装置以及蓄水池系统,后者包括雨水净化与有效容积确定;其中,设计混凝沉淀箱、过滤箱及储水箱,微纳米增氧系统增加水体溶解氧含量,可提高水体自净能力,达到雨水回灌地下水的标准。

摘  要：
The groundwater resources protection and restoration has been important for sponge urban construction, green building residential construction could be conducive to the water pollution control, so rainwater collection, as a basic technical requirement of green building, has been in large-scale promotion of its use. This study has discussed roofing rainwater collection of community separate buildings based on analyses of rainfall variation characteristics in Changsha and available potential of annual roof rain runoff, and designed roof rainwater collection systems composed of initial rainwater discarding device, and reservoir system with rainwater purification and effective volume determination, including coagulation-sedimentation tank, filter tank and storage tank with micro nano-aerobic system, which could increase the dissolved oxygen content in water to improve water self-purification ability up to the standard of rainwater for recharging groundwater. The study has provided certain reference for old village renovation construction of the green building community, and improvement of urban water environment.
