Ecological floating bed suitable for high-sediment large-flow rate water body

Abstract

The invention discloses an ecological floating bed suitable for a high-sediment large-flow rate water body. The ecological floating bed is formed by interconnecting two floating bed units, wherein each floating bed unit comprises floating bed fixing rods, hollow PVC tubes, wave eliminating rafts and a gauze; a plurality of hollow PVC tubes are horizontally arranged and fixed by the floating bed fixing rods so as to form a floating raft; the wave eliminating rafts are arranged below the two ends of the floating raft respectively; the gauze in which hollow columnar polyvinyl chloride short corrugated tube packing is packed is hung below the floating raft; and the gauze is positioned below the wave eliminating rafts. The ecological floating bed can treat the water body which contains high sediment and high phosphorus and nitrogen concentration, is suitable for a river with large flow rate, can build a landscape effect without influencing shipping, and can produce part of economic benefits.

Description

technical field [0001] The invention relates to a device for purifying polluted water quality rivers, in particular to an ecological floating bed suitable for high-sediment and high-velocity water bodies. Background technique [0002] Ecological floating bed, also known as artificial biological floating bed, soilless cultivation floating bed, biological floating island, etc., refers to planting plants on the bed floating on the water surface, using plant roots to absorb pollutants in the water body, and at the same time, the microorganisms attached to the plant roots are degraded More and more attention has been paid to the technology of effectively remediating water bodies by removing pollutants in water bodies. Up to now, ecological floating bed technology has become an important water quality restoration technology worldwide, and has been successfully applied in many lakes and rivers ecological restoration and ecological renovation projects. Ecological floating bed techn...

Problems solved by technology

At present, most floating beds use suspended packing, which is characterized by easy film formation, variable gaps that make it difficult to block, low cost, convenient assembly, stable water output, and good treatment effect. However, if the suspended matter in the water is large And when there are many, the filler wires will agglomerate, which greatly reduces the specific surface area actually used, and it is prone to broken wires and center rope breaks, which affects the service life, and its service life is generally 1 to 2 years.
