Ecological floating bed for repairing water body

Abstract

The invention provides an ecological floating bed for repairing a water body. The ecological floating bed comprises a floating bed main body, a box body and an ecological chamber, wherein the floatingbed main body is of a disc-shaped structure and comprises an outer-side annular bearing part for providing a buoyant force and an emergent aquatic plant planting disc; the box body is internally provided with a supporting layer, a matrix layer and a culture layer; two ends of the floating bed main body are fixedly connected with two ends of the box body through connection plates respectively. Theecological floating bed provided by the invention comprises the floating bed main body, the box body and the ecological chamber; the floating bed main body can be used for planting various floating-leaf water plants, emergent aquatic plants and floating plants; the box body is used for planting aquatic or terrestrial plants with a sewage purification function; the ecological chamber is internallyprovided with a carrier layer, a nutrient layer and a biological film layer; the biological film layer can be used for decomposing ammonia-nitrogen and phosphorus in a water body and reducing the content of nitrogen and phosphorus in the water body; the oxygen dissolving rate of the water body is easy to improve; and the floating bed main body, the box body and the ecological chamber are reasonably arranged, so that the effect of efficiently purifying the water body is realized.

Description

technical field [0001] The invention relates to the technical field of water body purification equipment, in particular to an ecological floating bed for water body restoration. Background technique [0002] Ponds, rivers and lakes and other water bodies are due to rainwater runoff, farmland receding water and other sewage discharges, resulting in the accumulation of pollutants in the water environment, which makes the pollution of the above-mentioned water bodies continue to increase, and the water environment is deteriorating day by day. With the deepening of awareness, more and more attention has been paid to the improvement of ponds, rivers and lakes. People began to respect and protect the natural features and ecological functions of ponds, rivers and lakes and other water bodies, and restore the above-mentioned The natural characteristics and biodiversity of the water body realize the harmonious development of man and nature. [0003] Ecological floating bed is a comm...

Problems solved by technology

[0004] However, due to the single water purification method of common floating beds and the limited ability of plant roots to absorb pollutants in water, ecological floating beds can only be used as an auxiliary means for ecological restoration of water bodies.

And because the dissolved oxygen available to the floating bed plants in the sewage is limited, the stems and leaves or the roots and leaves are prone to lack of oxygen and cause rot, which in turn pollutes the water body, and the water purification effect is poor.

[0005] Therefore, in view of the deficiencies in the prior art, it is necessary to study a kind of ecological floating bed with strong comprehensive water purification ability, which can effectively prevent plants from rotting due to underwater hypoxia.
