摘要
通过分析调蓄池在合流制排水系统中的工作原理得出,调蓄池的主要作用是增大系统的截流倍数。以滇池流域为例,对昆明主城的降雨资料进行分析,得出昆明地区降雨量与降雨强度的关系,并以此推导出合流制系统的截流倍数与溢流外排量之间的关系,进而得到合流制排水系统调蓄池容积的计算公式。
Through analyzing the working principle of rainwater storage tank in the combined sewer system, it was found that the main function of the tank was enlarging interception ratio of the sewer system. The calculation formulas of the tank volume in the combined sewer system in developed countries were enumerated, and taking Dianchi Lake Basin as an example, the rainfall data of Kunming were ana- lyzed. The relationship between rainfall amount and rainfall intensity in Kunming was obtained, and the relationship of interception ratio and overflow amount was deduced. Finally the calculation formula of the tank volume in the combined sewer system, which can be applied in Dianchi Lake Basin, was obtained.
