Bioretention pond with deep denitrification function
The invention belongs to the technical field of sponge city construction and rainwater treatment, and relates to a bioretention pond device with a deep denitrification function, which is suitable for retention and treatment of urban rainfall with relatively serious pollution and relatively high nitrogen and phosphorus concentration. The device comprises a planting chamber located on the upper portion of the inner side, a trickling filter pipe located on the lower portion of the inner side, a reaction tank located on the outer side and a drainage ring pipe located in the middle of the outer side. A front chamber plate, a rear chamber plate, a left chamber plate, a right chamber plate and a bottom chamber plate form a hollow cavity structure of the planting chamber; ventilation pipes are located at four corners of the planting chamber; the trickling filter pipe is positioned at the lower part of the planting chamber; the reaction tank comprises a front tank wall, a rear tank wall, a left tank wall, a right tank wall and a bottom tank wall; and a front pipe section, a rear pipe section, a left pipe section and a right pipe section form a mouth-shaped annular loop of the drainage ring pipe. The invention provides the bioretention pond device which is simple to operate and maintain and has outstanding rainwater retention capacity and relatively strong nitrification and denitrification capacity.
本发明属于海绵城市建设及雨水处理技术领域，涉及一种具有深度反硝化功能的生物滞留池装置，适用于污染相对严重、含氮磷浓度相对较高的城市降雨的滞蓄和处理。本发明包括位于内侧上部的种植室、位于内侧下部的滴滤管、位于外侧的反应池、位于外侧中部的排水环管。前室板、后室板、左室板、右室板、底室板组成种植室的中空腔体结构；换气管位于种植室的四角；滴滤管位于种植室的下部；反应池包括前池壁、后池壁、左池壁、右池壁、底池壁；前管段、后管段、左管段、右管段构成排水环管的“口”字型环形回路。本发明提供一种运行维护简单、具备突出的雨水滞蓄能力、较强的硝化反硝化能力生物滞留池装置。
