Vertical turning flow bioretention pond
The invention discloses a vertical turning flow bioretention pond, belongs to the field of municipal engineering, and provides a bioretention pond device capable of autonomously changing the oxygen-containing condition of rainwater, retaining and storing the rainwater and reducing suspended solids, nitrogen, phosphorus and organic matters in the initial rainwater. The vertical turning flow bioretention pond comprises a front tank wall, a rear tank wall, a left tank wall, a right tank wall, a tank bottom plate, a breather pipe, a left bottom partition plate, a right bottom partition plate, an overflow partition plate, a water passing vertical partition plate and a water distribution transverse partition plate. According to the vertical turning flow bioretention pond, an aerobic trickling filtration area is formed through the breather pipe and the water distribution transverse partition plate, so that the nitration effect of ammonium nitrogen is enhanced; through the water passing vertical partition plate and the overflow partition plate, firstly, a waterflooding anoxic saturation area is formed, and the denitrification effect of nitrate nitrogen is enhanced; a rainwater flowing path forms baffling, and the hydraulic retention time is prolonged; and thirdly, the rainwater retention capacity of the vertical turning flow bioretention pond is enhanced, the moisture required by life activities of plants and microorganisms is ensured, the biomass and activity of the plants and the microorganisms are improved, and the biological treatment capacity of the vertical turning flow bioretention pond is enhanced.
本发明公开了一种垂向转折流生物滞留池，属于市政工程领域，提供了一种能够自主改变雨水含氧情况，滞蓄雨水、降低初期雨水中的悬浮物、氮磷和有机物的生物滞留池装置。包括前池壁、后池壁、左池壁、右池壁、池底板、通气管、左底隔板、右底隔板、溢流隔板、过水竖隔板、布水横隔板。本装置通过通气管、布水横隔板形成好氧滴滤区，强化铵态氮的硝化作用；通过过水竖隔板与溢流隔板，一是形成淹水缺氧饱和区，强化硝态氮的反硝化作用；二是使雨水过流路径形成折流，增加水力停留时间；三是增强了本装置雨水的滞蓄能力，保证了植物、微生物生命活动所需水分，提升了二者的生物量和活性，增强了本装置的生物处理能力。
