谈天津市初期雨水调蓄池设计标准

On design standard for the primary rainfall storage tanks in Tianjin

以天津市中心城区为研究对象,统计分析了近30年的降雨资料,并结合雨水径流污染随降雨时间的变化规律,分析了不同调蓄标准下年径流污染控制总量和经济效益,进而归纳出适合天津市初期雨水调蓄池的设计标准。

Taking the downtown of Tianjin as the research object,the paper undertakes the statistic analysis of the rainfall documents in recent 30 years,analyzes the pollution control volume and economic benefit of the annual runoff under various storage standards by combining with the changing standard of the rainfall runoff pollution along with the rainfall time,sums up the design standard for the primary rainfall storage tanks which are suitable for Tianjin.
