【摘要】:傳輸型植被淺溝構造簡單、經(jīng)濟實用,是海綿城市建設的重點推廣技術之一。通過在深圳光明新區(qū)國家LID雨水綜合利用示范區(qū)的現(xiàn)場監(jiān)測研究,探討了中到大雨下傳輸型植被淺溝對污染物質以及雨水徑流總量、峰值流量的實際控制效果。結果表明,中到大雨下,傳輸型植被淺溝對SS、COD、NH_4~+-N、NO_3~--N、TN和TP的去除率分別為28.91%~67.29%、37.76%~64.57%、21.84%~34.65%、19.39%~25.99%、23.60%~39.97%和31.49%~48.83%,對徑流總量的削減率為50.9%~66.3%,且徑流峰值較降雨峰值滯后5~9 min;若設計重現(xiàn)期取1 a,深圳的傳輸型植被淺溝可接納相當于自身面積1.79倍硬質路面所產(chǎn)生的徑流。
[Abstract]:The transport vegetation shallow gully is one of the key techniques of sponge city construction because of its simple structure, economy and practicality. Based on the field monitoring study in the National lid Rain Water Comprehensive Utilization demonstration area of Guangming New District, Shenzhen, the actual control effect of the transport vegetation shallow gully on the pollutants, the total amount of Rain Water runoff and the peak flow rate under moderate to heavy rain is discussed. The results show that it rains from moderate to heavy rain, The removal rates of NTN and TP in the transport vegetation shallow gully are 28.91D 67.297.297.76x 64.5721.84kb, 34.65x, 19.399n 25.99kb, 39.97% and 31.4948.833.The total runoff reduction rate is 50.966.36.30.The peak runoff value is 59.9m lower than the peak rainfall peak, and if the recurrence period is 1 a, the transport vegetation gully in Shenzhen can be accepted by 39.97% and 31.4948.833.The peak runoff peak is 59.9min behind the peak rainfall peak; if the design recurrence period is 1 a, the transport vegetation gully in Shenzhen can be accepted. When the runoff produced by the hard road surface is 1.79 times its own area.
