Composite ecological floating bed suspended with biofilm carrier

Abstract

The invention discloses a composite ecological floating bed suspended with a biofilm carrier, the composite ecological floating bed comprises a floating bed frame and the biofilm carrier suspended below the floating bed frame, the floating bed frame is formed by splicing a rectangular floating plate and a plurality of plant floating plates arranged in the rectangular floating plate, plant groovesare arranged on the plant floating plates, and aquatic plants are placed in the plant grooves; the biofilm carrier is distributed in the circumferential direction of the plant floating plates, and root systems of the aquatic plants extend downwards to the biofilm carrier. Plant root system purification and microorganism purification are carried out synchronously, plant root systems can extend downwards to the upper portion of the biofilm carrier to form a purification section with the plant root systems and a biofilm acting together, a better purification effect is achieved, all the componentsare detachably connected, and materials are greatly saved through the arrangement of hanging buckles and pin shafts. The risk resistance of the floating bed is improved, and the economic cost is reduced.

Description

technical field [0001] The invention relates to an ecological floating bed, in particular to a composite ecological floating bed suspended with a biofilm carrier. Background technique [0002] In recent years, due to unreasonable fertilization methods of cultivated land and excessive discharge of pollutants, serious pollution of rivers, lakes and other water bodies and ecological environment damage have been caused. After a large amount of pollutants rich in nitrogen, phosphorus, and organic matter are discharged into water bodies, plankton in the water will be promoted. As a result, the dissolved oxygen content in the water decreases, other aquatic animals and plants are difficult to survive or die, the biological chain in the water is destroyed, the water body of rivers and lakes becomes stinky, and the water quality further deteriorates, threatening the health of river and lake ecosystems. [0003] Ecological floating beds are usually used to remediate water pollution in ...

AI Technical Summary

Problems solved by technology

Existing ecological floating beds are greatly affected by the flow velocity, and are easily washed away when the water flow is fast. A large amount of materials are consumed in the manufacturing process of the floating bed, resulting in a high economic cost of the floating bed. The ability to absorb and degrade is limited, and it is necessary to further develop the microbial degradation in the plant root environment
