Embodiment 1

[0030] according to figure 1 , 2 , 3, 4, this is applicable to the ecological floating bed with independent aeration function in the heavily polluted river with relatively high flow rate, including cylindrical floating bed body 1, bed body matrix 2, aquatic plants 3, aquatic animals 4, aeration device and fixing device . Aquatic plants 3 are planted on the bed matrix 2, aquatic animals 4 are cultivated in the bed, and the bed is connected to a fixing device. The cylindrical floating bed 1 is assembled by two concentric cylinders through PVC pipes 5, The aeration device is installed symmetrically around the cylindrical floating bed body.

[0031] The upper and lower bottoms of the concentric cylinders are tightened by fishing nets 8 and fixed on the PVC plastic pipe 5 with lead wires. The plants 3 are fixed in the fishing net holes at the upper bottom of the inner cylinder, and the substrate 2 is made of coconut fiber; One end of the root hollow PVC pipe 5 is fixedly connect...

Abstract

The invention provides an ecological floating bed with a self-aeration function suitable for a heavily polluted riverway with relatively high flow speed. The ecological floating bed is characterized in that aquatic plants grow on a bed body matrix; aquatic animals are bred in a barrel-shaped floating bed body; the barrel-shaped floating bed body is fixedly connected with aeration devices; the barrel-shaped floating bed body is formed by assembling two concentric barrels through a PVC (polyvinyl chloride) pipe; the aeration devices are symmetrically mounted at the periphery of the barrel-shaped floating bed body; the barrel-shaped floating bed body is connected with a fixing device. The ecological floating bed has the advantages that the dissolved oxygen content of a bed body system and a peripheral water body can be increased, so that the floating bed plants can grow satisfactorily; holes are formed in the periphery of the bed body to slow down the damage of water flow on the bed body system and prolong the hydraulic retention time of the water body passing through the bed body; filter-feeding fishes are bred, so that the biodiversity of the water body is improved and a certain economic value can be obtained; the ecological floating bed does not need other energy consumption and is simple in structure and easy to manufacture, and the pollutant purifying efficiency of the ecological floating bed is improved.

Description

technical field [0001] The invention relates to an ecological floating bed with an aeration device suitable for relatively high-velocity heavily polluted river channels, and belongs to the technical field of devices for purifying river channel water pollution. Background technique [0002] With the increase of population and the rapid development of urban construction, a large amount of domestic sewage and industrial wastewater containing nutrients are discharged into the river, polluting the water environment of the river and destroying the ecosystem of the river. Ecological restoration technology is very popular in river water pollution control. As a new type of eutrophic water body restoration technology, ecological floating bed takes ecological restoration as the basic principle, soilless cultivation technology as the basis, and polymer materials as the carrier. Modern agronomic technology, through the symbiotic relationship between species to achieve artificial ecosyste...
