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.
The existing problems in the calculation of rainwater utilization in buildings and plots are pointed out. The issues of runoff coefficient, water balance analysis, reservoir volume determination and benefit calculation are studied. The daily capacity of rainwater reservoirs is calculated according to the daily water balance method. Rainwater utilization, rainwater harvesting intensity and sinking area on the basis of the intensity of rainfall design flow calculation.According to the continuous 8-year rainfall data in Hefei City, the use of daily water balance method, a secondary school in Hefei and a The calculation and analysis of rainwater utilization in residential area is carried out, and suggestions are put forward for the determination of rainwater utilization mode and storage tank volume in urban buildings and communities, which provides a scientific basis for the utilization of urban rainwater.
