Abstract

La présente invention concerne un dispositif et un procédé délimination sur place de cyanobactéries hivernantes dans les sédiments lacustres et appartient au domaine technique de la recherche de lenvironnement hydrique. Le dispositif délimination sur place de cyanobactéries hivernantes dans les sédiments lacustres comprend une bobine de réactance avec une entrée inférieure ouverte. La bobine de réactance est installée directement sur les sédiments lacustres pour former un environnement interne fermé de cette première; des tamis sont disposés dans la bobine de réactance, des matériaux dabsorption sont placés sur les tamis, et un dispositif de perturbation deau est disposé dans une partie inférieure du tamis. Le dispositif de perturbation deau comprend des aubes de perturbation, et ces dernières tournent afin dentraîner le mouvement de leau. Le dispositif délimination sur place de cyanobactéries hivernantes dans les sédiments lacustres, selon la présente invention, est utilisé pour lélimination sur place des cyanobactéries, ce qui peut effectivement contrôler les toxines algales, cyanobactéries, azotes et phosphores.
