Coupling biofilm aeration flow artificial floating bed of eutrophic water purification system

The present invention discloses an artificial stream floating bed biofilm aeration coupling purification system eutrophic water bodies. Including biological biofilm floating bed and artificial aeration flow; hanging said biological membrane carrier is a flexible fibrous filler, and the composition of the floating bed biofilm floating bed units; the artificial flow biofilm aeration is installed in the bottom of the floating bed unit the plurality of plug-flow aerator actuated in the same direction to form a circular flow of water, oxygen and water. The system uses a number of floating sheets biofilm fixed by the fixing element pile, connecting rod, and arranged in an oval, with the intermediate guide wall, is provided below the floating bed plug-flow aerator. Compared with the general floating bed biofilm, the increased flow of artificial aeration, the water enhancing the flowability, without providing a separate aeration system, a high efficiency of contaminant removal, can effectively slow down the level of eutrophication; water may be directed, dynamic changes in water quality, the regulation of the operating mode, the system more stable, efficient, energy saving.
