Embodiment 1

[0039] Such as Figure 1 to Figure 4 As shown, a treatment device for eliminating black and odorous water bodies in rural areas includes a filter disinfection tank 1, a sedimentation resting tank 2 and an aeration and oxygenation tank 3 arranged in sequence, and the entrance of the filter disinfection tank 1 is provided with A detachable first filter assembly 4, the first filter assembly 4 is used for coarse residue filtration, and a detachable second filter assembly 5 is arranged in the filter disinfection tank 1, and the second filter assembly 5 is used for fine Filtration and adsorption, the area below the second filter assembly 5 is a disinfection zone 6, which is provided with a stirring assembly 8 and a disinfectant feeding channel 7 installed on the filter disinfection pool 1, the disinfection zone 6 The first water pump 9 is arranged on the side away from the mixing assembly 8 in the zone 6 and is connected to the sedimentation resting tank 2 through a first pipeline 1...

Embodiment 2

[0061] This embodiment provides a method of using the management device in the first embodiment.

[0062] The black and odorous water is added from the top of the filter disinfection pool 1, the first filter assembly 4 filters out the large debris in the black and odorous water, and the second filter assembly 5 finely filters the black and odorous water And adsorb harmful organisms and odors, the filtered water enters the disinfection zone 6, adds a disinfection and sterilizing agent through the disinfectant feeding channel 7, and mixes with the water body under the agitation of the stirring assembly 8; the first The water pump 9 pumps the sterilized water into the settling pool 2. During the pumping process, the flocculant is added through the feeding assembly 11 along with the flow, and the water entering the settling pool 2 is left to stand. After settling for a period of time, the second water pump 12 descends to the clear water area according to the water body conditions ...

Embodiment 3

[0064] The difference between the present embodiment and the first embodiment is that another structure of branch bar arrangement structure is provided.

[0065] Such as Figure 7 As shown, the branch rod body 17 is arranged in a cross, the end of the branch rod body 17 is connected with an outer ring rod body 29, and the middle part of the branch road rod body 17 is provided with an inner ring rod body 30, and the branch rod body 17 is provided with an inner ring rod body 30. 17. The aeration nozzles 28 are provided on the outer peripheries of the outer ring rod body 29 and the inner ring rod body 30 .

[0066] The branch rod body with this structure can increase the aeration area, and can also increase the aeration range. When the aeration and oxygenation tank 3 is set in a cylindrical shape, the aeration effect is better, and the overall layout structure It will also be more compact.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a treatment device for eliminating black and odorous water bodies in rural areas. Background technique [0002] Black and odorous water body refers to the water body in urban rivers that is obviously discolored due to pollution and emits disgusting odors. In the process of urbanization and industrialization in China, due to the direct discharge of industrial, agricultural and domestic wastewater into rivers, large-scale pollution of urban water bodies, water bodies Eutrophication eventually forms black and smelly water bodies; this phenomenon is also common in rural areas, and due to weak environmental protection awareness, a lot of domestic garbage is directly discharged into water bodies, causing further pollution of water bodies. [0003] Chinese invention patent application (publication number: CN112777856A) disclosed a black and odorous water body treatment device i...
