Example Embodiment

[0032] Example 1:

[0033] like Figure 1-2 As shown, the embodiment of the present invention provides a water quality improvement system for a black and odorous water body in a river channel, including a river channel 2, a support frame 5 is arranged on the river channel 2, the lower end side wall of the support frame 5 is fixedly connected with a float 6, and the upper end of the support frame 5 is A drive motor 8 is fixedly connected, one end of the drive motor 8 is extended with a motor shaft and the side wall of the motor shaft is provided with a conveyor belt 7, and an aeration fence 4 is arranged in the river 2 and on one side of the support frame 5, and the aeration fence 4 A counterweight 3 is fixedly connected to the lower end of the air aeration fence 4, an air pipe 9 is fixedly connected to the upper end of the air aeration fence 4, an air pump 10 is fixedly connected to the other end of the air pipe 9, and a filter screen 1 is arranged downstream of the river chan...

Example Embodiment

[0036] Embodiment 2:

[0037] A method for improving the water quality of a black and odorous water body in a river, comprising the following steps:

[0038] S1 detects emission sources

[0039] Detect the dumping places of sewage and garbage along the river channel 2, and carry out rectification to stop the discharge of sewage and garbage;

[0040] S2 channel 2 dredging

[0041] Use a sand mining boat to dredging the river channel 2, and remove the silt in the river channel 2. If the depth of the silt exceeds the depth of the water storage and flood discharge involved in the river channel 2, then dredging the design depth by 20-30cm, and adopt building construction The generated construction waste or the earthwork excavated during construction is backfilled to the design depth of the river channel 2, which can solve the problem that the construction waste cannot be treated. into organic fertilizer and increase economic income;

[0042] S3 layout cleaning system

[0043] ...

Abstract

The invention provides a method and a system for improving water quality of black and odorous water in rivers, belonging to the field of water treatment. The system for improving water quality of black and odorous water in rivers comprises a river channel, wherein a support frame is arranged on the river channel; a buoy is fixedly connected to the side wall of the lower end of the support frame; the upper end of the support frame is fixedly connected with a driving motor; a motor shaft is arranged at one end of the driving motor in an extending mode, and a conveying belt is arranged on the side wall of the motor shaft; an aeration fence is arranged in the riverway and on one side of the support frame; the upper end of the aeration fence is fixedly connected with an air pipe; the other endof the air pipe is fixedly connected with an air pump; and a filter screen is arranged on a downstream position of the river channel. The method for improving the water quality of the black and odorous water body of the river channel comprises the steps of detecting a discharge source, dredging the river channel, arranging a cleaning system, culturing algae and culturing fishes. Through river dredging and aeration treatment and introduction of algae and fishes, the water body is purified, and economic income is increased.

Description

technical field [0001] The invention relates to the field of water body treatment, in particular to a water quality improvement method and system for black and odorous water bodies in river courses. Background technique [0002] Black odor is an extreme phenomenon of organic pollution, which is caused by the lack of oxygen in the water body and the corruption of organic matter. The black and odorous state is an extreme state of water body, and its own characteristics are also very different from other states. Its physical and chemical environment is characterized by strong reduction, extremely serious organic and inorganic pollution, and the water body has peculiar smell, which is no longer suitable for the survival of aquatic organisms. The aquatic vegetation is degraded or even extinct. The food chain is broken, the food web is fragmented, the ecosystem structure is seriously unbalanced, and its functions are seriously degraded or even lost. [0003] The invention adopts...
