In recent years, with the rapid development of industrial and agricultural industries and the acceleration of urbanization process in China, the discharge amount of industrial wastewater and domestic sewage is increased day by day, the development of water resources is increased, the water pollution condition is intensified, water ecological systems in many areas are seriously damaged, and the water environment problems of water quality deterioration, water eutrophication, biological community degradation and the like are very common. The water environment problem is one of the main environmental problems currently faced by China. The image of the submerged plant is like an underwater forest when the submerged plant is stably grown, the submerged plant can absorb nutrient elements such as nitrogen, phosphorus and the like to inhibit water eutrophication, has an inhibiting effect on algae, and can also enrich oxygen in the water through photosynthesis.

The growth of submerged plants in the actual environment is influenced by a plurality of environmental factors, when the water body is seriously polluted and the transparency is low, the underwater illumination is smaller than the optical compensation point of the submerged plants, the aquatic plants cannot grow well, and the illumination intensity becomes the main limiting factor of the growth of the submerged plants at the moment, so that the function of purifying the water quality of the submerged plants is weakened.

At present, the ecological floating bed technology is widely researched and applied as a novel eutrophic water body in-situ restoration and control technology, but the ecological floating bed technology has some problems and defects in application. The current commonly used floating bed carriers are plastic, bamboo and the like, and the materials have poor corrosion resistance and stability, so that the service life of the floating bed is very limited, and secondary pollution is also brought. Meanwhile, the water flow condition of the polluted water body and the size of the stormy waves can influence the ecological floating bed system, generally speaking, the stormy waves not only can damage the bed system, but also can shorten the hydraulic retention time, and the treatment effect is reduced. In addition, the floating bed lacks the ability to purify deep water.

For example, the bed body is made of metal materials, and has high cost and high requirement on a buoyancy system during floating, wherein the bed body is published by CN101356881A, a lifting submerged plant growth bed disclosed in Chinese patent publication No. 2, month 4 in 2009, and a manufacturing and application method thereof, and a submerged aquatic plant floating bed disclosed in Chinese patent publication No. CN201648116U in 11, month 24 in 2010; the Chinese patent with publication number CN201777934U and publication number CN101356881A and publication number 2009, 2.4, the liftable submerged plant growth bed and the manufacturing and application method thereof all adopt moso bamboos as a buoyancy system, and nutrient substances can be released into a water body after the moso bamboos are rotten to cause secondary pollution; in the 'mesh box type ecological sinking bed with adjustable sinking position', publication number CN202272773, publication number 6/13/2012, publication number CN201777934U, publication number 2011, 3/30/2011, and publication number CN201999795U, publication number 2011, 10/5/2011, the position of the bed body under water is adjusted through the stay wire connected with the underwater fixed pile, so that the construction difficulty and cost are increased, and later maintenance is not facilitated; the lifting type double-positioning modularized submerged plant water quality purification device disclosed in Chinese utility model with publication number CN201420662632.X and publication date 2015 3, 11 adopts a UPVC (unplasticized polyvinyl chloride) submerged bed main body and a buoyancy system frame, does not use a fixed pile, realizes the sinking and floating of the submerged bed main body in a pumping and irrigating mode, but does not solve the pumping power problem and does not realize the automatic regulation of the depth of the submerged bed according to an optical compensation point, and needs manual control regulation, thereby increasing the economic and labor cost; the novel three-dimensional ecological floating bed purification system disclosed in Chinese patent with publication number CN108751416A and publication number CN108812276A and publication number 2018, 11 and 16 do not relate to the problem of optical compensation points and cannot realize automatic adjustment.
