Problems solved by technology

Among them, the water reoxygenation technology is to artificially aerate the water body, thereby changing the anaerobic environment in the water body, but the aeration and reoxygenation of the water body is affected by many factors such as water depth, temperature, and air-to-water ratio, and its reoxygenation effect is not high.
More importantly, just aerating the water body cannot change the anaerobic environment of the sediment, and the N, P nutrients and various pollutants in the sediment will still be released into the water body. The pollution effect is greatly affected, and the efficiency of reoxygenation in water is not very high
[0006] For the dredging method, because many black and odorous rivers have been seriously polluted for a long time, and the sediment is seriously silted, the dredging of the upper sediment will lead to the exposure of the lower sediment and contact with the overlying water body, thereby forming secondary pollution to the water body. Simultaneous dredging The cost of the method is higher, and the economic cost is higher

Embodiment 1

[0034] Embodiment 1 is basically as attached Figure 1-Figure 3 Shown: a bottom mud floating mud layer dosing aeration device, including a main body support, the main body support includes a vertical pipe support 9 made of carbon steel pipes and a solid cast iron base support, and the vertical pipe support 9 is painted for anti-corrosion deal with. The base bracket comprises a base 10 and a cylindrical base tube 14, the base 10 is welded on the bottom of the base tube 14, the standpipe support 9 is slidably connected in the base tube 14, the side wall of the base tube 14 is provided with a threaded hole, the vertical The side wall on the pipe support 9 is provided with several vertically arranged threaded holes, the threaded holes on the standpipe support 9 and the threaded holes on the base pipe 14 are fixed by bolts 12, and the bolts 12 are fixed on the standpipe support 9 with different The threaded holes, thereby realizing the adjustment to the height of standpipe support...

Embodiment 2

[0039] The difference between embodiment 2 and embodiment 1 is that the support frame 11 is no longer welded on the standpipe support 9, combined with Figure 4 and Figure 5 As shown, the standpipe support 9 is rotatably connected with a turntable group through bearings, the first turntable 15, the second turntable 18 and the third turntable 19 connected coaxially by the turntable set, the first turntable 15, the second turntable 18 and the third turntable 19 are arranged sequentially from top to bottom, the diameters of the first turntable 15, the second turntable 18 and the third turntable 19 become smaller successively, and eight arcs are arranged on the first turntable 15, the second turntable 18 and the third turntable 19. The arc-shaped groove 16 on the first turntable 15, the arc-shaped groove 16 on the second turntable 18 and the arc-shaped groove 16 on the third turntable 19 are vertically opposite to each other. Because the diameters of the first rotating disk 15, ...

Abstract

The invention relates to the field of treatment of black and odorous water bodies, in particular to a device for dosing and aerating a bottom mud floating mud layer, which includes a height-adjustable main body bracket, the main body bracket includes a support frame, and an aeration part and a dosing part are placed on the support frame A first connecting piece installed on the main frame is communicated between the aeration element and the external aeration pipeline, and a second connecting piece installed on the main body support is communicated between the dosing piece and the external dosing pipeline. This scheme can suppress the release of N, P nutrient salts and various pollutants in the sediment during the treatment of black and odorous water, and improve the reoxygenation efficiency in the water.

Description

technical field [0001] The invention relates to the field of treatment of black and odorous water bodies, in particular to a drug-dosing and aerating device for bottom mud floating mud layer. Background technique [0002] Urban black and odorous water body refers to the general term for water bodies that present unpleasant colors and / or emit unpleasant odors in urban built-up areas. The water pollution of urban rivers is mainly manifested as black and odorous water bodies. The direct cause is that dissolved organic pollutants are anaerobically decomposed due to insufficient dissolved oxygen in the water body, resulting in different types of black and odorous substances. [0003] The "black odor" of rivers not only stimulates the senses, making people feel unpleasant and disgusting, but also the gas components emitted by the black and odorous water, such as hydrogen sulfide and ammonia, can directly endanger human health. If people smell the foul-smelling gas, they will refl...
