The water guiding hole 10 on one side of the sludge collecting groove 9 helps to guide the clear water after sedimentation treatment out, while preventing the water flow from carrying away the settled sludge. The middle bottom of the gradually changing flow guide plate 6 is provided with a clamping interface matched with the structure of the support frame 5. The clamping interface top inner wall of the gradually changing flow guide plate 6 is welded and fixed with a clamping block 13. The connection between the support frame 5 and the gradually changing flow guide plate 6 is provided with a clamping groove matched with the structure of the clamping block 13. When the gradually changing flow guide plate 6 is installed or maintained, the operator only needs to align the clamping interface of the gradually changing flow guide plate 6 with the corresponding position on the support frame 5, and gently push it. The clamping block 13 will be embedded in the corresponding clamping groove on the support frame 5 to achieve firm locking. This not only simplifies the installation process, but also ensures the stability of the gradually changing flow guide plate 6 under the action of water flow, preventing it from being displaced or falling off due to water flow impact. At the same time, this detachable design facilitates regular inspection and cleaning of the gradually changing flow guide plate 6, ensuring its long-term efficient operation and improving the maintenance convenience and reliability of the entire sedimentation tank main body 1. The gradually changing flow guide plate 6 gradually reduces in height to form a sloping surface, and the two side surfaces of the gradually changing flow guide plate 6 are uniformly provided with a plurality of convex edges 14. The convex edges 14 and the gradually changing flow guide plate 6 are of an integral structure. This structure helps to guide the smooth flow of water, reduces turbulence near the water inlet, and enables suspended solids to settle more effectively. The convex edges 14 not only enhance the structural strength of the flow guide plate, but also further refine the water flow path, ensuring more uniform water distribution in the entire sedimentation tank.
[0018] Working principle: When using the environmental engineering wastewater treatment sedimentation tank, first adjust the angle of each lateral flow guide wing 3 in advance. By rotating the screw column 12 and cooperating with the rotating interface 11, ensure that each lateral flow guide wing 3 achieves the best guiding effect according to the actual water flow. When wastewater enters the sedimentation tank main body 1 from the water inlet, the several lateral flow guide wings 3 supported by the horizontal support 2 effectively guide and uniformly distribute the water flow. The flow guiding holes on the horizontal part of the lateral flow guide wing 3 further refine the water flow path, reducing the water flow speed. As the water flow smoothly slides along the sloping surface of the gradually changing flow guide plate 6, the convex edges 14 reduce the vortex and lateral disturbance in the water flow, enabling suspended solids to settle more stably. The water flow continues to flow. When the water flow reaches the inner bottom wall of the sedimentation tank main body 1, the sloping bottom surface 7 guides the water flow and the settled sludge to slide along the slope to the sludge collecting groove 9. The water guiding hole 10 on one side of the sludge collecting groove 9 ensures that the clear water after sedimentation treatment can be smoothly guided out. In the entire process, the clamping interface at the middle bottom of the gradually changing flow guide plate 6 cooperates with the clamping groove on the support frame 5, and the clamping block 13 is firmly locked by welding to ensure the stability of the gradually changing flow guide plate 6 under the action of water flow, thereby completing a series of work.
