Abstract
(EN)
A system for intercepting nitrogen and phosphorus in a countryside landscape type ecological ditch, comprising a sand buffer zone, an ecological ditch unit, an interception conversion pool, and a bund plant hedge. The sand buffer zone, the ecological ditch unit, and the interception conversion pool are sequentially disposed in a continuous ditch along a water flow direction. The bund plant hedge is disposed on a bund on one side or two sides of the ditch. Also disclosed is a method for intercepting nitrogen and phosphorus in water drained from a farmland for the system for intercepting nitrogen and phosphorus in a countryside landscape type ecological ditch.
(FR)
L'invention concerne un système d'interception d'azote et de phosphore dans un fossé écologique rural, comprenant une zone tampon de sable, une unité de fossé écologique, un bassin de conversion d'interception et un muret de protection végétal. La zone tampon de sable, l'unité de fossé écologique et le bassin de conversion d'interception sont disposés de manière séquentielle dans un fossé continu dans le sens de l'écoulement de l'eau. Le muret de protection végétal est disposé sur un ou deux côtés du fossé. L'invention de système d'interception d'azote et de phosphore dans un fossé écologique rural concerne également un procédé pour intercepter l'azote et le phosphore dans l'eau drainée à partir d'une terre agricole.
