合肥市建筑与小区雨水利用

Study of rain water utilization in Hefei buildings and communities

指出了目前建筑与小区雨水利用计算中存在的问题,对雨水利用径流系数、水量平衡分析、储水池容积确定、效益计算等问题进行了研究,提出按逐日水量平衡法确定雨水储水池容积、计算雨水利用量,根据产流期间雨水收集强度和汇水面积上的损失强度计算雨水设计流量.以合肥市连续8年日降雨量资料为基础,运用逐日水量平衡法,对合肥市某中学和某小区雨水利用进行了实例计算分析.对城市建筑与小区雨水利用方式和储水池容积的确定提出了建议,为城市雨水利用提供了科学依据.

Some problems existed in the calculation for rain water utilization in buildings and communities are pointed out; the calculation of discharge runoff coefficient, rain water balance analysis, determination of storage basin capacity, and benefits analysis are researched; and then the storage basin capacity and rain water utilization can be determined by daily water balance method; and the design flow of rain water can be calculated according to rain water collection intensity and loss intensity on catchment area during runoff producing. Based on the eight years rainfall information, rain water utilization of some school and community in Hefei are studied. Finally, some suggestions for rain water utilization in city are put forward.
