[0002] Industrial production and municipal life generate large amounts of wastewater containing pollutants such as suspended particles, colloidal impurities, and organic matter. If this wastewater is discharged directly without effective treatment, it will cause serious pollution to the water environment and soil ecology, disrupt the ecological balance, and even threaten human health. Currently, there are various wastewater treatment methods. Among them, flocculation clarification technology is widely used in wastewater pretreatment or advanced treatment due to its simple operation, relatively low cost, and good treatment effect. Its basic principle is to add flocculants to wastewater, causing the colloidal particles and suspended impurities in the wastewater to lose stability, collide and aggregate to form larger flocs, and then these flocs settle under the action of gravity, thereby achieving solid-liquid separation in the wastewater and clarifying the wastewater.

Uneven and insufficient mixing of flocculant and wastewater leads to poor flocculation reaction effect, and unreasonable water flow distribution in the sedimentation area results in low sedimentation efficiency. Some fine flocs may be discharged with the effluent. Summary of the Invention

[0025] Example 1: Please refer to Figure 1 , Figure 3 A flocculation clarification wastewater treatment device includes a tank 1, a flocculation reaction zone 2, and a sedimentation separation zone 3. The flocculation reaction zone 2 is installed on the left side inside the tank 1. The flocculation reaction zone 2 is sequentially installed with a fast stirring zone 4, a medium stirring zone 5, and a slow stirring zone 6 from the left side inside. The sedimentation separation zone 3 is installed on the right side inside the tank 1. A wastewater inlet 11 is installed on the left side outside the tank 1. A clean water outlet 9 is installed on the upper right side outside the tank 1. A flocculant inlet 12 is installed on the upper left side outside the tank 1. Bottom supports 17 are symmetrically connected and installed on the left and right sides of the lower side outside the tank 1. A conical sludge hopper 10 is connected and installed in the middle of the lower side outside the tank 1. The flocculation reaction zone 2 and the sedimentation separation zone 3 are connected by a flow guide hole partition 25.
[0026] A stirring shaft 13 is installed on the right side of the fast stirring zone 4, medium stirring zone 5 and slow stirring zone 6 respectively. A high-speed stirring blade 14 is installed on the stirring shaft 13 of the fast stirring zone 4, a medium-speed stirring blade 15 is installed on the stirring shaft 13 of the medium stirring zone 5, and a low-speed stirring blade 16 is installed on the stirring shaft 13 of the slow stirring zone 6. After the wastewater undergoes flocculation reaction in the flocculation reaction zone 2, it enters the sedimentation separation zone 3 through the guide hole baffle 25.
[0027] Furthermore, housing 1 provides an installation location for flocculation reaction zone 2, which in turn provides installation locations for fast stirring zone 4, medium stirring zone 5, and slow stirring zone 6. The right side wall inside fast stirring zone 4, medium stirring zone 5, and slow stirring zone 6 provides an installation location for stirring shaft 13. A high-speed stirring impeller 14 is installed on the stirring shaft 13 in fast stirring zone 4, a medium-speed stirring impeller 15 is installed on the stirring shaft 13 in medium stirring zone 5, and a low-speed stirring impeller 16 is installed on the stirring shaft 13 in slow stirring zone 6. Flocculation reaction zone 2 is used to complete the sludge... The water and flocculant react fully. The sedimentation separation zone 3 is responsible for solid-liquid separation of the wastewater after the flocculation reaction. To achieve the input of wastewater and the output of treated clean water, the wastewater to be treated enters the equipment through the wastewater inlet 11. The flocculant is precisely added to the rapid stirring zone 4 of the flocculation reaction zone 2 through the flocculant inlet 12 to ensure thorough mixing with the wastewater. The purified clean water after sedimentation is discharged through the clean water outlet 9. The bottom support 17 is used to ensure the overall balance of the equipment, and the conical sludge hopper 10 is used to collect the sludge generated during the sedimentation separation process. The flocculation reaction zone 2 adopts a segmented reaction design, with a fast stirring zone 4, a medium stirring zone 5, and a slow stirring zone 6 installed sequentially from the left side. Through zoned treatment with different stirring intensities, the formation and growth of flocs are gradually promoted. The fast stirring zone 4, as the initial stage of the flocculation reaction, mainly functions to rapidly mix the wastewater with the newly added flocculant. A high-speed stirring paddle 14 is installed on the stirring shaft 13 in this zone, generating strong shear force through high-speed rotation, causing the flocculant to rapidly diffuse in the wastewater and initially breaking down the stability of colloidal particles in the wastewater. The medium stirring zone 5... The water effluent from the fast stirring zone 4 is connected to the stirring shaft 13, where a medium-speed stirring paddle 15 is installed. The medium-speed stirring can avoid the damage to the initially formed micro-flocs caused by high-speed stirring, and can also promote the collision and aggregation of micro-flocs to form medium-sized flocs. The slow stirring zone 6 is the final stage of the flocculation reaction. A low-speed stirring paddle 16 is installed on the stirring shaft 13. The low-speed stirring provides a mild reaction environment for the flocs, allowing the medium-sized flocs to further aggregate and grow into larger-sized stable flocs, creating favorable conditions for subsequent sedimentation and separation.
[0028] Example 2: Please refer to Figure 2 and Figure 3 A flocculation and clarification wastewater treatment device, wherein the fast stirring zone 4, medium stirring zone 5 and slow stirring zone 6 are separated by vertical partitions 19 respectively. Baffles 20 and guide plates 21 are symmetrically installed on both sides of the inner wall of the fast stirring zone 4, medium stirring zone 5 and slow stirring zone 6 respectively. Two sets of baffles 20 are installed in the fast stirring zone 4, and one set of baffles 20 is installed in the medium stirring zone 5 and slow stirring zone 6. The fast stirring zone 4, medium stirring zone 5 and slow stirring zone 6 are connected to the vertical partitions 19 through bottom gaps for water flow.
[0029] Furthermore, the inner walls of the fast stirring zone 4, medium stirring zone 5, and slow stirring zone 6 provide installation positions for baffles 20 and guide plates 21. The internal structure of the flocculation reaction zone 2 has been further optimized. By adding vertical baffles 19, baffles 20, and guide plates 21, the water flow guidance and flocculation reaction effect are enhanced. The fast stirring zone 4, medium stirring zone 5, and slow stirring zone 6 are connected to the vertical baffles 19 through bottom openings. Under the impetus of gravity and subsequent water flow, the sewage flows from the bottom opening of the fast stirring zone 4 into the medium stirring zone 5, and then from the bottom opening of the medium stirring zone 5 into the slow stirring zone 6. The baffles 20 extend the residence time of the sewage in each reaction zone, ensuring that the flocculant and sewage fully contact and react. The number of baffles 20 in each zone is set differently according to the reaction requirements. The fast stirring zone 4 has two sets of baffles 20. The high-speed stirring paddle 14 forms a complex water flow path. The rotating water flow generated by high-speed stirring forms turbulence under the obstruction of the baffle plate 20, which enhances the mixing uniformity of flocculant and sewage and quickly breaks down the stability of colloidal particles. At the same time, the guide plate 21 guides the water flow along a preset direction to avoid mixing dead zones caused by local eddies. A set of baffle plates 20 is installed in both the medium stirring zone 5 and the slow stirring zone 6. The baffle plate 20 in the medium stirring zone 5, in conjunction with medium-speed stirring, reduces water flow turbulence and promotes the aggregation of small flocs through collision. The baffle plate 20 in the slow stirring zone 6 further reduces the water flow speed and, in conjunction with low-speed stirring, provides a mild growth environment for the flocs, helping them form more stable flocs. In this stage, the guide plate 21 mainly plays the role of stabilizing the water flow and preventing the flocs from breaking due to water flow turbulence.
[0030] Example 3: Please refer to Figure 1 , Figure 2 and Figure 3 A flocculation clarification wastewater treatment device, wherein a clear water zone 22 is installed on the upper side inside the sedimentation separation zone 3, the clear water zone 22 is connected to the clear water outlet 9, a fine-pore grid 24 is installed on the lower side of the clear water zone 22, an upward inclined pipe 8 is installed in the middle inside the sedimentation separation zone 3, the upper side of the upward inclined pipe 8 is connected to the fine-pore grid 24, and a sedimentation zone 7 is installed on the lower side inside the sedimentation separation zone 3, the sedimentation zone 7 is connected to the bottom of the upward inclined pipe 8;
[0031] The upward-passing inclined tube 8 has honeycomb channels 23 evenly distributed on it;
[0032] Furthermore, the housing 1 provides an installation location for the sedimentation separation zone 3, which in turn provides installation locations for the clear water zone 22, the fine-pore grid 24, the upward-passing inclined pipe 8, and the sedimentation zone 7. The housing 1 provides an installation location for the clear water outlet 9, and the upward-passing inclined pipe 8 provides an installation location for the honeycomb channel 23. The clear water zone 22 serves as the final area of the sedimentation separation process. The water in the clear water zone 22 has undergone solid-liquid separation, resulting in clear water. It can be discharged through the clear water outlet 9 to complete the treatment process. Its spatial design ensures the stable collection of clear water, avoiding water flow disturbance from affecting the lower separation process. The fine-pore grid 24 has small and evenly distributed pores, which can intercept incompletely settled micro-flocculations or impurities, preventing them from entering the clear water zone 22 with the water flow, further improving the effluent water quality. At the same time, the grid structure does not obstruct the upward flow of clear water, ensuring smooth water flow. The wastewater enters the clear water zone 22. The upward inclined pipe 8 adopts a hexagonal inclined pipe design, which improves the sedimentation efficiency by increasing the sedimentation area and shortening the settling distance of the flocs. After the flocculation reaction, the wastewater enters the bottom of the upward inclined pipe 8 from the sedimentation zone 7. The water flows upward along the inclined pipe, and the flocs slide down the inner wall of the inclined pipe to the sedimentation zone 7 under the action of gravity. The clarified water then passes upward through the upward inclined pipe 8 and enters the fine mesh grid 24. The inclination angle of the upward inclined pipe 8 is usually 60°, which not only ensures the smooth sliding of the flocs, but also maximizes the use of space. The layered design of the sedimentation separation zone 3 forms a complete process of "sedimentation-filtration-collection". First, the wastewater undergoes preliminary sedimentation in the sedimentation zone 7, then undergoes efficient solid-liquid separation through the upward inclined pipe 8, and then undergoes secondary filtration through the fine mesh grid 24. Finally, it is collected in the clear water zone 22 and discharged.
[0033] Example 4: Please refer to Figure 3 and Figure 4 A flocculation and clarification wastewater treatment device, wherein the bottom of the sedimentation zone 7 is connected to the conical sludge hopper 10, and sludge pipes 18 are connected and installed on the left and right sides of the bottom of the conical sludge hopper 10, and the left sludge pipe 18 is connected to the bottom of the middle stirring zone 5.
[0034] Furthermore, the sludge pipe 18 on the left is connected to the bottom of the intermediate stirring zone 5, forming a sludge return channel. When the sludge separated from the sedimentation zone 7 accumulates to a certain amount in the conical sludge hopper 10, the control valve of the sludge pipe 18 on the left is opened. Some of the sludge can return to the intermediate stirring zone 5 by its own gravity and the pressure difference inside the equipment, and mix with the newly entered sewage. Since the returned sludge contains a large number of active flocculants, it can enhance the flocculation reaction effect of the intermediate stirring zone 5 and improve the sewage treatment efficiency. The sludge pipe 18 on the right is mainly used to discharge excess sludge to prevent excessive accumulation of sludge in the conical sludge hopper 10 from affecting the normal operation of the equipment.
[0035] Example 5: Please refer to Figure 5 and Figure 6A flocculation and clarification wastewater treatment device, wherein drive units 26 are embedded in the inner wall of the box 1 at the connection between the fast stirring zone 4, the medium stirring zone 5 and the slow stirring zone 6, respectively. A horizontally mounted drive motor 27 is installed inside the drive unit 26. A gear 28 is installed on the left side of the drive motor 27. The gear 28 is connected to the gear shaft 29. The gear shaft 29 is connected to the stirring shaft 13. The drive unit 26 is connected to an external power source through a wire 30.
[0036] Furthermore, housing 1 provides an installation position for drive unit 26, which in turn provides installation positions for drive motor 27, gear 28, and gear shaft 29. When the equipment is started, external power supplies power to the drive motor 27 of each drive unit 26 via wire 30. After being energized, drive motor 27 outputs torque, driving gear 28 on the left to rotate. Gear 28 meshes with gear shaft 29, converting the horizontal rotational motion into the vertical rotational motion of gear shaft 29. Gear shaft 29 then transmits power to stirring shaft 13, driving stirring shaft 13 and the stirring blades on the shaft to rotate synchronously. The drive motors 27 of the fast stirring zone 4, medium stirring zone 5, and slow stirring zone 6 have different speeds. Through the power transmission structure described above, they can provide suitable stirring speeds for the three stirring zones respectively. The high-speed stirring in the fast stirring zone 4 can quickly disperse the flocculant in the wastewater and form preliminary flocs. The medium-speed stirring in the medium stirring zone 5 promotes the collision and combination of flocs, making them gradually larger. The low-speed stirring in the slow stirring zone 6 further stabilizes the floc structure without destroying the large flocs that have already formed. Through the linkage between the drive unit 26 and the stirring shaft 13, the three stirring zones work together to complete the graded flocculation reaction of the wastewater and improve the flocculation effect.
[0037] Working principle: Wastewater to be treated enters the fast stirring zone 4 of the flocculation reaction zone 2 through the wastewater inlet 11 on the left side of the tank 1. At the same time, flocculant is precisely added to the fast stirring zone 4 through the flocculant inlet 12. External power supplies the drive unit 26 through the wire 30. The drive motor 27 outputs torque to the fast stirring zone 4, medium stirring zone 5, and slow stirring zone 6, which is transmitted to the stirring shaft 13 through the gear 28 and gear shaft 29, driving the corresponding stirring blades to rotate. The high-speed stirring blade 14, together with the two sets of baffles 20 on both sides, forms turbulence and initially forms small flocs. The water flow is guided into the medium stirring zone 5 by the notch at the bottom of the vertical baffle 19 and the guide plate 21, avoiding dead zones in the water flow. The medium-speed stirring blade 15, together with a set of baffles 20, forms medium-sized flocs. The water flow enters the slow stirring zone 6 through the bottom notch. The low-speed stirring blade 16, together with a set of baffles 20, makes the water flow into the slow stirring zone 6. More stable flocs are formed and eventually enter the sedimentation separation zone 3 through the guide hole baffle 25. The wastewater carrying large flocs first settles in the sedimentation zone 7. Some flocs sink to the bottom and enter the conical sludge hopper 10. The remaining wastewater enters the upward inclined pipe 8. The water flows upward along the honeycomb channel 23. Under the action of gravity, the flocs slide down the inner wall of the 60° inclined pipe to the sedimentation zone 7, shortening the settling distance and improving the separation efficiency. The clarified water passes upward through the fine mesh grid 24 and enters the clear water zone 22 to collect. Finally, it is discharged through the clear water outlet 9 to complete the purification. Of the sludge collected in the conical sludge hopper 10, part flows back to the middle stirring zone 5 through the left sludge pipe 18 to enhance the reaction effect by utilizing the active flocs in the sludge. The excess sludge is discharged through the right sludge pipe 18 to avoid excessive sludge accumulation affecting the operation of the equipment.
