Plain river network slope bank pollution interception system
The invention discloses a plain river network slope bank pollution interception system, and belongs to the technical field of ecological engineering. The system is composed of multiple stages of strip-shaped ecological interception units parallel to a riverway shoreline, the strip-shaped ecological interception units are arranged from top to bottom along a slope surface, each ecological interception unit comprises filler, planting soil, plants, a water distribution pipe, a water collection pipe and a water outlet vertical pipe, and the units are connected through connecting pipes. The system adopts a side water inlet, underflow and turn-back type water inlet mode, and water flow transversely and horizontally underflows along the first-stage ecological interception unit from the water distribution pipe, passes through the water collection pipe, the water outlet vertical pipe, the connecting pipe and the water distribution pipe and is turned back to the second-stage ecological interception unit until being discharged into a receiving water body. Aiming at the characteristics that flat land indexes are deficient and a large amount of agricultural non-point source pollution is accepted for a long time in a plain river network area, the river channel slope bank is fully utilized, and the slope bank pollution intercepting system is constructed according to local conditions to locally intercept and purify agricultural non-point source pollution. The device can be widely applied to farmland recession, aquaculture wastewater, tail water of rural sewage treatment stations and the like to guarantee the water quality of plain river networks.
本发明公开一种平原河网坡岸污染拦截系统，属于生态工程技术领域。该系统由多级平行于河道岸线的条带状生态拦截单元组成，沿坡面从上至下布设，所述的生态拦截单元包括填料，种植土，植物，布水管、集水管和出水竖管，单元之间由连接管相连。系统采用侧面进水，潜流、折返式的进水方式，水流从布水管沿一级生态拦截单元横向水平潜流，经集水管、出水竖管、连接管、布水管折返于二级生态拦截单元，直至排入受纳水体。本发明针对平原河网地区平地指标匮乏，长期接纳大量农业面源污染的特点，充分利用河道坡岸，因地制宜构建坡岸污染拦截系统，就地拦截净化农业面源污染。可广泛应用于农田退水、养殖废水、农村污水处理站尾水等，保障平原河网水质。
