Rainwater garden capable of removing nitrogen and reducing emission of greenhouse gas nitrous oxide
The invention discloses a rainwater garden capable of removing nitrogen and reducing emission of greenhouse gas nitrous oxide. The rainwater garden comprises a biological retention area (18) and a rainwater recycling area (12), and the biological retention area (18) comprises a gravel layer (10), a transition layer (9), a chalcopyrite matrix layer (8), a charcoal matrix layer (7), a planting layer (6), a covering layer (5) and a water storage layer (17) in sequence from bottom to top; a first perforated drain pipe (11) is arranged in the gravel layer (10), a water outlet of the first perforated drain pipe is lifted to be flush with the top of the chalcopyrite matrix layer (8), and a water outlet of the first perforated drain pipe (11) is connected into a rainwater recycling area (12). The method has the technical effects that dissolved nitrogen can be removed, and emission of strong greenhouse effect gas N2O is reduced.
本发明公开了一种脱氮又减排温室气体氧化亚氮的雨水花园，它包括生物滞留区（18）和雨水回用区（12），生物滞留区（18）由下至上依次为砾石层（10）、过渡层（9）、黄铜矿基质层（8）、生物炭基质层（7）、种植层（6）、覆盖层（5）和蓄水层（17）；砾石层（10）中设有第一穿孔排水管（11），第一穿孔排水管抬升出水口高度与黄铜矿基质层（8）顶部齐平，第一穿孔排水管（11）出水口接入雨水回用区（12）。本发明的技术效果是：既能去除溶解态氮，又减少了强温室效应气体N2O排放。
