Problems solved by technology

[0003] Existing river and lake restoration technologies use aquatic plant planting, ecological floating beds or artificial aeration to degrade pollutants in water bodies to purify water bodies, but aquatic plant planting relies solely on plant growth to remove nitrogen and phosphorus pollutants, and it is difficult to obtain high pollution The removal rate of pollutants; due to the insufficient dissolved oxygen in the black and odorous water body of the ecological floating bed, the growth of microorganisms attached to the plant roots is slow, and the purification effect of the floating bed system is not good; while the mechanical aeration equipment is time-consuming and laborious to install at the bottom of the water, and it is not beautiful when floating on the water surface. Need to provide additional power supply facilities
The use of enhanced bypass purification technology requires a large amount of treatment and a short cycle, large construction scale and investment, high operating costs, and the ecological self-purification efficiency of rivers and lakes in situ has not been fully utilized and utilized

Embodiment 1

[0026] combine figure 1 , the present embodiment provides a mobile river channel black and odorous water ecological restoration device and method, including solar energy 1, ecological floating bed 2, aeration device 3, microbial film-hanging device 4 and underwater pushing flow device 5; solar energy 1 and aeration The device 3 is electrically connected to the underwater push-flow device 5 to provide power for it. The push-flow device 5 pushes the ecological floating bed 2 to move freely in the water body. The ecological floating bed 2 is planted with aquatic plants 21. The bottom of the ecological floating bed is provided with a microbial hanging film device 4.

[0027] The aeration device 3 includes a blower aerator 31 and a gas delivery pipe 33 arranged at the bottom of the floating bed, and the gas outlet of the blower aerator communicates with the gas delivery pipe 33 through a gas delivery pipe 34; The delivery pipe 33 is provided with a number of aeration holes, and th...

Embodiment 2

[0036] As the specific scheme of embodiment 1, in the present embodiment, the ecological floating bed, the rectangular frame delivery pipe and the strip-shaped biomimetic carbon fiber aquatic plants are connected vertically successively; The filler stretches vertically and can swing properly within a certain range in the water to enhance the probability of microbial attachment and the accumulation of pollutants such as nitrogen, phosphorus, and organic matter in the water body, provide nutrients for aquatic plants in ecological floating beds, and improve the ability of aquatic plants to absorb and degrade COD, nitrogen, and phosphorus .

[0037] In this embodiment, the rectangular frame is foam, PVE pipe or waste rubber tire, the side length of the frame ranges from 4m to 10m, the rectangular frame is arranged at the bottom of the ecological floating board, and the gas delivery pipe and the microbial product delivery pipe It is arranged in the frame along the frame; a threaded...

Embodiment 3

[0039] As a specific solution of Example 1, in this example, the plant planting tank is filled with a soil layer and a multifunctional nanocomposite layer. Specifically, the soil layer is composed of one or more of planting soil, activated carbon, zeolite, slag and ceramsite, with a thickness ranging from 10 to 15 cm and a solid particle size of 2 to 5 mm; the multifunctional nanocomposite layer is from top to bottom The bottom layer includes ammonia nitrogen removal layer, phosphorus removal layer, heavy metal removal layer and COD removal layer. The thickness of the ammonia nitrogen removal layer is 2-4cm; the thickness of the phosphorus removal layer is 2-4cm; 10-20cm; the particle size of nanocomposite particles is 15-20mm, and the filling rate is 60%-70%.

Abstract

The invention discloses a mobile ecological restoration device and method for riverway black and odorous water. The device includes a solar energy device, an ecological floating bed, an aeration device, a microorganism film-hanging device and an underwater flow-pushing device; the solar energy device is electrically connected with the aeration device and the underwater flow-pushing device and provides power for the aeration device and the underwater flow-pushing device; the flow-pushing device pushes the ecological floating bed to freely move in a water body. The device has the advantages of low cost and simple structure, adopts an ecological technology to purify the water body from multiple dimensions, and remarkably improves the purification efficiency of the eutrophic water body in rivers and lakes.

Description

technical field [0001] The invention relates to a device and method for effectively improving the ecological restoration of black and odorous water in a river course, and belongs to the technical field of river course ecological management. Background technique [0002] With the acceleration of urbanization and the increase of population, a large amount of urban domestic sewage is directly discharged into rivers, resulting in water pollution and water ecological damage, and the water bodies of rivers and lakes are black and smelly or eutrophic. Especially in areas with dense river networks in the Jiangnan Plain, there are many urban Duantou Rivers and closed waters. Rivers and lakes have large water areas, poor water fluidity, wide sources of pollution, relatively simple water ecosystems, small water environment capacity and poor self-purification ability. The water environment of rivers and lakes is deteriorating day by day, and biodiversity is destroyed, seriously affecti...
