Novel artificial ecological riverbed and construction method

Abstract

The invention discloses a novel artificial ecological riverbed and a construction method. The novel artificial ecological riverbed comprises a composite fiber ecological mat with the thickness of 50mm, an aquatic plant body, a riverbed body and mud nails. Compared with the prior art, the novel artificial ecological riverbed is good in environmental protection performance, low in implementation cost, convenient to construct and capable of being widely applied to some eutrophicated, black and odorous water areas and urban landscape water areas needing water quality improvement, aquatic plants bred in the composite fiber ecological mat gradually grow as time goes on in the later period, the effects of beautifying the environment, purifying the water quality, improving the climate and effectively controlling water and soil loss can be achieved, and meanwhile, the diversity of species can be maintained; the plane shape of the novel artificial ecological riverbed can be arranged in a diversity mode, and a graceful landscape environment can be created according to the forms of the aquatic plants and diversified combination modes, so that a leisure and entertainment space is provided for people.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a novel artificial ecological river bed and a construction method thereof. Background technique [0002] With the rapid development of social economy and urban construction, a large amount of production and domestic sewage are discharged into the river, which makes the current situation of river pollution severe, and the water ecosystem has weakened and degraded to varying degrees. transition zone disappears, biodiversity sharply declines, and habitat shrinks; especially in the hard riverbeds that dominate urban rivers, aquatic plants are difficult to grow, which greatly reduces the ecological self-purification ability of rivers; at the same time, there are a large number of organic Pollutants are deposited on the river bed, forming a black and smelly river, and the water quality is eutrophic, making the water environment of the river worse and worse; [0003] E...

Problems solved by technology

[0002] With the rapid development of social economy and urban construction, a large amount of production and domestic sewage are discharged into the river, which makes the current situation of river pollution severe, and the water ecosystem has weakened and degraded to varying degrees. transition zone disappears, biodiversity sharply declines, and habitat shrinks; especially in the hard river beds that dominate urban rivers, it is difficult for aquatic plants to grow, which greatly reduces the ecological self-purification capacity of the river; at the same time, there are a large number of organic Pollutants are deposited on the river bed, forming a black and smelly river, and the water quality is eutrophic, making the water environment of the river worse and worse;

[0003] Existing technologies mostly use gravel, slag, construction waste, clay, peat and other materials to build ecological riverbeds. These materials will increase the height of the riverbed to a certain extent, and at the same time bring organic pollution risks to the river course, and the existing technologies Ecological riverbeds mainly rely on aquatic plants to absorb and degrade organic pollutants in clay. Aquatic plants are not effective in dealing with sudden pollution incidents. Rise in water level or decrease in transparency during the rainy season of the river will affect the decontamination effect of aquatic plants; at the same time, the materials used in the prior art Too much, the construction is inconvenient, and the implementation cost is relatively high, which is not conducive to widespread promotion; in view of these defects, it is necessary to design a new type of artificial ecological riverbed
