Description

Technical Field

[0001] This invention relates to the field of environmental governance technology, and specifically discloses a method and apparatus for ecological governance of pollution in reservoir bays of lake-type drinking water sources. Background Technology

[0002] Currently, three main methods are generally used to address the impact of rural domestic sewage in upstream lakes and reservoirs: first, relocating residents; second, collecting domestic sewage and treating it through artificial wetlands or other facilities before discharge; and third, constructing a pre-treatment reservoir to purify the sewage flowing down from the catchment area before it enters the lake or reservoir. The first method can effectively address the impact of rural domestic sewage, but it is often difficult to implement due to high relocation costs or lack of land to resettle relocated farmers. The second method can purify the sewage to some extent, but because farmers are generally scattered, construction and operation costs are high, requiring a large land area, and the purified sewage still contains some pollutants, failing to completely eliminate the impact on the water source. The third method requires land for the construction of a pre-treatment reservoir, which many lakes and reservoirs lack, and it is also impossible to completely eliminate pollutants in the sewage. To address the shortcomings of existing methods for treating pollution in reservoir bays of lake-type drinking water sources, this application proposes an ecological treatment device for reservoir bay pollution in lake-type drinking water sources that can effectively solve the above-mentioned technical problems.

An extrusion hole connected to the rear end of the spiral extrusion cylinder 3061 is provided at the lower rear side of the processing housing 301. A spiral extrusion blade 3062 is disposed within the spiral extrusion cylinder 3061, the diameter and pitch of which gradually decrease.

When the drained algae enters the spiral extrusion cylinder 3061, it is compressed and shaped under the action of the spiral extrusion blade 3062, and then extruded from the end opening of the spiral extrusion cylinder 3061.

[0027] Meanwhile, a fixed-angle rotary motor 3064 is installed on the rear inner wall of the processing housing 301. The output shaft of the fixed-angle rotary motor 3064 extends into the end of the processing housing 301 and is connected to a connecting plate 3065. Several connecting rods 3066 are evenly connected circumferentially to the connecting plate 3065. Specifically, there are 3 to 6 connecting rods 3066 evenly connected circumferentially to the connecting plate 3065.

[0032] In addition, this embodiment also discloses a treatment method for the treatment device disclosed in Embodiment 1 or Embodiment 2, including the following steps: Step 1: Locate areas of algae accumulation in lake / reservoir-type drinking water sources and identify these areas as requiring remediation. Step 2: Send the above-mentioned treatment device to the water area to be treated, and control the dredging net to dredge the floating algae on the surface of the water. Then, the dredged algae is transported to the processing machine box by the conveyor belt. Step 3: After the floating algae enters the processing machine box and is drained through the collection hopper, it enters the spiral compaction device. The spiral compaction device presses the floating algae into the compaction pan. Step 4: Finally, move the compacted algae to the top and use a pressing mechanism to discharge the compacted algae blocks into the press material placement trough.
