[0027] Reference Figures 1-3 An organic wastewater settling treatment device is provided, which includes an inlet pipe 1, a mixing chamber 2, a multi-stage settling chamber and a sludge collection tank 4.

[0028] The inlet pipe 1 is connected to the mixing chamber 2, which is connected to the multi-stage settling chamber via the guide pipe 5. The multi-stage settling chamber includes at least three interconnected settling units 301. Each settling unit 301 has an inclined bottom surface 302. The final settling unit 301 has an outlet. The sludge collection tank 4 is installed at the bottom of the multi-stage settling chamber and is connected to it. In application, wastewater settles step by step through at least three interconnected settling units 301, avoiding the problem of insufficient single-stage settling efficiency and improving the removal rate of suspended solids. At the same time, the inclined bottom surface 302 promotes the natural sliding of sludge to the sludge collection tank 4, reducing the frequency of manual cleaning. Furthermore, the sludge collection tank 4 is directly connected to the settling units 301, enabling centralized sludge recycling and reducing the risk of secondary pollution.

[0029] Reference Figure 1 and Figure 2 A spiral guide plate 201 is installed on the inner wall of the mixing chamber 2. The pitch of the spiral guide plate 201 gradually increases from the water inlet end to the water outlet end. In application, a pitch gradient design is adopted. The small pitch at the water inlet end enhances the mixing intensity, while the large pitch at the water outlet end reduces the flow velocity, avoids floc breakage, and improves the flocculation effect.

[0030] Reference Figure 1 and Figure 2 The inclined bottom surface 302 has an inclination angle of 10-15°, and the inclination angle of the bottom surface 302 gradually increases along the flow direction. In application, the 10-15° inclination angle is optimized to balance the sludge sliding efficiency and the space occupied by the equipment, and to avoid the structural complexity caused by the inclination angle being too large.

[0031] Reference Figure 2 and Figure 3 A symmetrical support column 6 is installed between the bottom of the mixing chamber 2 and the top of the settling unit 301. In application, the symmetrical support structure is used to distribute the load of the mixing chamber 2 and the settling unit 301, enhance the overall stability, and extend the service life of the equipment.

[0032] Reference Figure 2 and Figure 3 The settling unit 301 has a removable cover plate 303 at its top. The bottom of the cover plate 303 has an integrally formed retaining edge 3031 that corresponds to the top cavity of the settling unit 301. The cover plate 303 can be detachably installed on the top of the settling unit 301 through the retaining edge 3031. In application, the use of the retaining edge 3031 can simplify the disassembly and assembly process of the cover plate 303 and facilitate internal cleaning and maintenance.

[0033] Reference Figure 2 and Figure 3The top of the cover plate 303 is provided with an observation window 3032 for observation. In application, the observation window 3032 is designed to allow real-time observation of the settlement status, timely adjustment of operating parameters, and improved operation convenience.

[0034] Reference Figure 1 and Figure 2 The sludge collection tank 4 is located at the lowest end of the settling unit 301. The bottom of the sludge collection tank 4 has an inclined surface 401. A sludge outlet 402 is provided on one side of the sludge collection tank 4, and the lowest point of the inclined surface 401 is connected to the sludge outlet 402. In application, the inclined surface 401 is used as a guide to guide the sludge outlet 402 to discharge in a concentrated manner, avoid residue in the tank, and reduce the risk of blockage.

[0035] The working principle of this utility model is as follows: Organic wastewater enters the mixing chamber 2 through the inlet pipe 1, and forms a vortex under the action of the spiral guide plate 201. It reacts fully with the added flocculant to generate flocs. Then the mixed liquid enters the sedimentation unit 301 through the guide pipe 5 for three-stage sedimentation treatment. Finally, the clear water is discharged through the outlet, and the sludge enters the sludge collection tank 4 through the inclined bottom surface 302. The sludge in the sludge collection tank 4 slides along the inclined surface 401 to the sludge outlet 402. The staff regularly transports it out for dewatering to avoid accumulation.

[0036] This utility model provides an organic wastewater sedimentation treatment device. By using a multi-stage sedimentation unit 301 in conjunction with an inclined bottom surface 302, it can achieve step-by-step deep treatment of wastewater, significantly improving sedimentation efficiency. At the same time, sludge automatically gathers into the sludge collection tank 4 through the inclined bottom surface 302, and is then quickly discharged in conjunction with the guide slope 401, which can greatly reduce manual intervention and lower operation and maintenance costs.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
