Problems solved by technology

These artificial biological floating islands are not only expensive (the cost per square meter in the United States is 200-1000 US dollars, and Japan 200,000-200,000 yen), but also large in size, heavy in quality, and very inconvenient to use and operate. Artificial biological floating islands are mainly used for the cultivation of economic crops, and the scope of application is also limited, so it has no promotion value in my country

Embodiment Construction

[0020]Polyethylene plastic is molded into a disc-shaped polyethylene plastic monomer floating bed body (3) with a diameter of about 50 centimeters, and a polystyrene foamed plastic floating body (3) is placed in the circular hole in the middle of the disc-shaped monomer floating bed body ( 1), the bottom of which has a polystyrene foamed plastic floating body draw-in slot (6) for fixing with the disc-shaped monomer floating bed body (3). Plants are planted in the planting tank (2) of the disc-shaped monomer floating bed around the polystyrene foamed plastic floating body. There are planting tank partitions (5) that divide the planting tank into multiple grids in the tank. The planting tank partition can not only The planting groove is divided into a plurality of small grooves so as to plant different plants, and the strength of the floating bed body of the disc-shaped polyethylene plastic monomer can be increased to play a role of tensile resistance. The lower end of each disc...

Abstract

The invention relates to a soft plant floating bed which is applied in revetment and water purification, which is a composite plant cultivation apparatus on water that adopts a disk-shaped single floating bed as one unit, wherein, a plurality of hygrophytes or amphiphytes are cultivated in the floating bed to form a floating bed that can float in the water; meanwhile, the aim of in-situ remediation and the control of the eutrophic water can be reached by using the plant to provide the biological cleaning function on the eutrophic water in lakes, rivers and channels. The main characteristics or effects of the floating bed are that: 1. the invention is used for acting the biological purification on eutrophic water in different waters; 2. one end of the floating bed is fixedly connected to the bank, which provides protection to the hydro-fluctuation belt and bank of reservoirs, lakes, rivers and channels. When the water level rises, the plant in the floating bed which grows on the water can absorbs the water nutrition enrichment to decrease the eutrophication degree; when the water level decreases, the floating bed covers the hydro-fluctuation belt to provide wave absorption and a protection layer for the bank.

Description

technical field [0001] The invention relates to a water planting device for revetment and water purification, which is especially suitable for water purification and embankment protection of reservoirs, lakes, rivers and ditches with sinking zones. Background technique [0002] With the development of industrial and agricultural production and the continuous improvement of people's living standards, a large amount of industrial wastewater and domestic wastewater are discharged into rivers, lakes and reservoirs, and the water environment is polluted to varying degrees. According to the survey data of 131 lakes and 50 large and medium-sized reservoirs in the country: the water quality pollution of the lakes and reservoirs is relatively serious. Among the 131 major lakes, 89 lakes are polluted to varying degrees, accounting for 67.9% of the total number of lakes and the total area of ​​the lakes. 62.3%, of which there are 28 seriously polluted lakes (super V water), accounting ...
