Problems solved by technology

[0005] However, some ecological floating islands will hang biological fillers on the bottom to increase the removal efficiency of pollutants by hanging membranes on the fillers. However, this method still has its limitations, such as insufficient reoxygenation of the water body, and a single pollutant removal factor.
In addition, traditional artificial floating islands mostly adopt fixed installation methods, which are difficult to drive and fix

Embodiment 1

[0044] In order to achieve the purpose of ecological restoration by removing ammonia nitrogen in the water body under aeration conditions through biological media, removing phosphorus in the water body through phosphorus removal media, and further purifying the water body through plant roots on floating islands; Governance, decentralized treatment of rural domestic sewage, and natural water purification projects are widely used. Refer to figure 1 As shown, in this embodiment, the submerged bioreactor for water body ecological restoration includes a water surface ecological floating island 100 , a submerged reaction device 200 , and an aeration component 300 . Specifically, the water surface ecological floating island 100 can float on the water surface and use the established efficient artificial ecosystem to reduce the pollution load in the water body. Here, the ecological floating island is a kind of water quality aimed at eutrophication. Artificial floating islands with the ...

Embodiment 2

[0052] In this embodiment, in order to improve the utilization rate of oxygen in the aeration process of this system, and it is easy to install and dismantle, easy to clean, and has a long service life, such as figure 2 Shown is an aeration assembly 300 , including a vertical air delivery pipe 301 , a horizontal air delivery pipe 302 , an aeration hole 303 , a plug 304 and an elastic microporous pipe sleeve 305 . Specifically, the horizontal air delivery pipe 302 is vertically communicated with the vertical air delivery pipe 301; and the wall of the horizontal air delivery pipe 302 is provided with an aeration hole 303; The microporous pipe sleeve 305 is sleeved on the outer side 302 of the transverse air delivery pipe. Further, the elastic microporous sleeve 305 is made of elastic material, which is a composite elastic material synthesized from polymer activated carbon, rubber, long-acting antibacterial agent, and hydrophobic preservative. The micropore density on the surfa...

Embodiment 3

[0055] In the above embodiment, the water surface ecological floating island 100 and the submerged reaction device 200 are linked to realize the water surface ecological floating island 100 floating on the water surface, and the submerged reaction device 200 is suspended on the bottom of the water surface ecological floating island 100 through the link and immersed in water. Therefore, in order to realize the quick connection between the ecological floating island 100 on the water surface and the submerged reaction device 200 in this embodiment, and to facilitate disassembly and maintenance in the later stage, the difference from the above embodiment is that a quick connection line A is also provided, refer to figure 1 and Figure 4 Among them, the upper and lower ends of the quick connection line A are respectively connected to the water surface ecological floating island 100 and the submerged reaction device 200 . specific,

[0056] Such as Figure 4~5 Shown is a schemati...

Abstract

The invention discloses an immersed bioreactor for ecological restoration of a water body. The immersed bioreactor comprises a water surface ecological floating island, an immersed reaction device andan aeration assembly, wherein the water surface ecological floating island can float on the water surface and utilizes a constructed efficient artificial ecosystem to reduce pollution load of the water body; the immersed reaction device and the aeration assembly are arranged at the bottom of the immersed reaction device. The immersed bioreactor has the beneficial effects as follows: 1, ammonia and nitrogen in the water body are removed by biological media under the aeration condition, phosphorus in the water body is removed by phosphorus removing media, and strengthened purification of wateris realized; 2, the ecological floating island is connected to the top of an underwater immersion device through chains, the water body is further purified by plant root system on the floating island,and the purpose of ecological restoration is achieved accordingly; furthermore, the immersed bioreactor is widely applicable to control of black-odor rivers, decentralized treatment of rural domesticwastewater and water purification engineering of natural water body.

Description

technical field [0001] The invention relates to the technical field of water environment ecological treatment, in particular to a submerged bioreactor used for water body ecological restoration. Background technique [0002] In recent years, water eutrophication is the process of deteriorating water quality due to the enrichment of nutrients such as nitrogen and phosphorus in water. In recent years, with the development of industry and the increase of population, the pollution of water resources has become more and more serious. Industrial wastewater, urban domestic sewage, fertilizers and pesticides in farmland are discharged without treatment, ecological damage and water quality deterioration continue to occur. Eutrophic water will promote the rapid reproduction of algae, and some algae will emit a fishy smell. When the algae die and decompose, the COD and BOD values ​​​​in the water will increase sharply, and the water quality will deteriorate, leading to the death of fis...
