Plant ecological floating bed

Abstract

The invention discloses a plant ecological floating bed which comprises a floating bed carrier, wherein a solar aeration device is arranged on the carrier; emergent plants are planted on the floating bed carrier; a microbial load bed is arranged below the water surface; the microbial load bed and the floating bed carrier are arranged in parallel through a connecting piece. An emergent plant bed body provided by the invention is made of polystyrene materials and is corrosion-resistant, frostproof, environment-friendly and long in service life; hardy plants are planted on a planting bed, so that an ecological floating bed system can also purify the water in winter. According to the invention, the emergent plants are combined with microorganisms, so as to form a double-treatment system of the emergent plants and the microorganisms, and promote the quick degradation and transformation of pollutants.

Description

technical field [0001] The invention belongs to the technical field of ecological environment engineering, and relates to the ecological reconstruction and recovery technology of natural and artificial rivers and lakes, in particular, it relates to sediment-type, hard The field of ecological restoration and water purification of bottom-shaped water bodies, in particular relates to a plant ecological floating bed. Background technique [0002] With the rapid development of industry and the acceleration of urbanization, the pollution of lakes, rivers and other water bodies is increasing day by day. A large number of rivers in cities have become black and smelly. The shortage of water resources has gradually become an important problem to be solved in modern society. [0003] The artificial ecological floating bed is an artificial composite structure that uses ecological principles to target eutrophic water bodies and degrade the COD, nitrogen, and phosphorus contents in the wa...

AI Technical Summary

Problems solved by technology

But at present, most of the river water bodies have deteriorated into black and odorous water bodies, and it is difficult to meet the needs of plant growth and microbial activities only by the oxygen released by plant roots

Insufficient oxygen makes it difficult for plants planted in water to survive, and most of the microorganisms formed are anaerobic, which reduces the treatment efficiency

[0004] Among the existing ecological floating bed technologies, for example, the Chinese patent with the publication number CN203668116U discloses "A Plant and Microorganism Combined Ecological Settling Bed", which overcomes the problem of low efficiency of a single artificial sinking bed, and effectively submerged plants Combined with microorganisms, but it is more difficult to hang the film in the early stage

The Chinese patent with the publication number 204643971U discloses "Eco-sinking bed-immobilized microorganism coupling device for water body purification", which manually adjusts the position of the sinking bed through the lifting device and solves the growth limitation of submerged plants in areas with insufficient light transmission problem, but its on-site construction is more difficult, which not only increases the cost, but also brings inconvenience to the later maintenance
