[0014] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0015] This utility model discloses a high-efficiency wastewater treatment sedimentation device. The device mainly includes an inlet mixing reaction well 1, an inclined tube sedimentation tank 2, a first partition wall 8, a control platform 11, a dosing device 5, a first sludge discharge pipe 7, an outlet well 3, a second partition wall 9, a second sludge discharge pipe 6, a sludge discharge pump 4, a support column 13, a bracket 10, an inclined sedimentation tube 12, and an electrical control cabinet 19. The inlet mixing reaction well 1 and the inclined tube sedimentation tank 2 are separated by the first partition wall 8. The top of the inlet mixing reaction well 1 has a device inlet 20, and the end of the inlet mixing reaction well 1 has a control platform 11. The dosing device 5 is installed on the control platform 11 and communicates with the inlet 20. The bottom of the first partition wall 8 has a water passage hole 18 that connects the inlet mixing reaction well 1 and the inclined tube sedimentation tank 2. A first sludge pipe 7 is arranged in the center, and an outlet well 3 is installed at the end of the inclined tube sedimentation tank 2. A second partition wall 9 separates the inclined tube sedimentation tank 2 and the outlet well 3. A triangular outlet weir is set on the upper part of the second partition wall 9, which connects the inclined tube sedimentation tank 2 and the outlet well 3. A sludge trough 17 is set at the bottom of the inclined tube sedimentation tank 2. A second sludge pipe 6 is arranged in the center of the bottom of the sludge trough 17. The first sludge pipe 7 and the second sludge pipe 6 are connected. A sludge pump 4 is installed on the control platform 11. The first sludge pipe 7 and the second sludge pipe 6 are connected to the sludge pump 4. A support column 13 is installed at the top of the sludge trough 17. A bracket 10 is installed at the top of the support column 13. The sedimentation inclined tube 12 is supported and installed inside the inclined tube sedimentation tank 2 by the support column 13 and the bracket 10. An electrical control cabinet 19 is installed on the control platform 11. The dosing device 5 and the sludge pump 4 are electrically connected to the electrical control cabinet 19.

[0016] like Figure 1 As shown, a drainage pump 15 is installed inside the water outlet well 3, and the drainage pump 15 is electrically connected to the electrical control cabinet 19. Under the control of the electrical control cabinet 19, the drainage pump 15 installed inside the water outlet well 3 discharges the treated clean water from the device, thereby realizing the purification and discharge of wastewater.

[0017] like Figure 3 As shown, the sedimentation tank 17 has two sets, and the sedimentation tank 17 is set with a V-shaped structure, so that the sludge automatically gathers to the second sludge pipe 6 in the center.

[0018] The sedimentation inclined tube 12 is made of honeycomb polyethylene. Water flows upward through the honeycomb polyethylene sedimentation inclined tube 12. The special hexagonal structure of the sedimentation inclined tube 12 produces a shallow pool effect. Flocs form a thin layer of sediment on the surface of the tube wall of the sedimentation inclined tube 12, which improves the treatment efficiency by 3-5 times compared with traditional sedimentation tanks.

[0019] Work process:

[0020] Wastewater enters the inlet mixing reaction well 1 through the inlet 20 of the device. At this time, the dosing device 5 on the control platform 11 automatically adds flocculant or coagulant according to the parameters set by the electrical control cabinet 19. The agent and wastewater are fully mixed in the reaction well by the vortex effect, so that the suspended solids form larger flocs. The mixed wastewater flows smoothly into the inclined tube sedimentation tank 2 through the water passage 18 at the bottom of the first partition wall 8. Since the water passage 18 is located at the bottom of the first partition wall 8, it can avoid the impact of water flow on the sedimentation effect. At this time, the water flow direction changes, and the larger suspended particles first settle to the bottom of the inlet mixing reaction well under the action of gravity. The primary sludge can be periodically discharged through the first sludge discharge pipe 7. The wastewater entering the inclined tube sedimentation tank 2 is settled by the action of the sedimentation inclined tube 12. The sedimentation inclined tube 12 is made of honeycomb polyethylene material and is supported and installed inside the inclined tube sedimentation tank 2 by the support column 13 and the bracket 10. This material and structure increases the surface area and sedimentation path of the wastewater, making the wastewater settle more effectively. Suspended solids have more opportunities to contact the surface of the inclined tube and settle down. The sediment gradually sinks into the sedimentation trough 17 at the bottom of the inclined tube sedimentation tank 2. The sedimentation trough 17 has two sets and is set in a V-shape, which is conducive to the aggregation of sediment. After sedimentation treatment, the clear water rises to the upper part of the inclined tube sedimentation tank 2 and flows into the effluent well 3 evenly and stably through the triangular effluent weir at the top of the second partition wall 9. The drainage pump 15 installed inside the effluent well 3, under the control of the electrical control cabinet 19, discharges the treated clear water to achieve the purification and discharge of wastewater. The first sludge discharge pipe 7 arranged at the bottom center of the inlet mixing reaction well 1 is connected to the second sludge discharge pipe 6 arranged at the bottom center of the sedimentation trough 17 at the bottom of the inclined tube sedimentation tank 2, and is connected to the sludge discharge pump 4 installed on the control platform 10. When it is necessary to discharge sediment, the electrical control cabinet 19 controls the sludge discharge pump 4 to start, and discharges the sediment in the inlet mixing reaction well 1 and the inclined tube sedimentation tank 2 through the sludge discharge pipe, without the need to empty the wastewater or manually dredge.
