Technical Field

[0002] In the field of wastewater treatment, the treatment of high-concentration wastewater has always been an important issue in environmental protection. This type of wastewater typically contains large amounts of suspended solids, colloidal particles, and organic pollutants. If improperly treated and directly discharged, it will cause serious harm to the ecological environment.

[0003] Traditional high-concentration wastewater treatment technologies suffer from low separation efficiency and high energy consumption. In existing technologies, primary separation devices often only intercept large particulate impurities, have poor removal effects on fine suspended solids, and require external high-energy-consuming equipment, resulting in high operating costs.

This device innovatively employs a multi-stage separation design, which not only ensures that the treated wastewater consistently meets discharge standards, but also offers significant advantages over traditional technologies, such as high separation efficiency and low energy consumption. It can be widely applied to the treatment of challenging wastewater in industries such as chemical, pharmaceutical, and dyeing. Utility Model Content

Water guide holes are provided on the outer walls of both the front and rear ends of the primary separation pipe, and the multiple water guide holes are respectively located between the connected separation nets and the water baffles.

[0009] Preferably, the upper part of the separation filter box is provided with two secondary separation plates that are distributed vertically, and the two secondary separation plates are respectively left with gaps between them and the inner walls of the front and rear ends of the separation screen. Multiple diversion baffles are fixedly connected to the upper part of the two secondary separation plates.

[0010] Preferably, the plurality of diversion baffles are curved in the direction of wastewater flow, and the lower side of each of the plurality of diversion baffles is provided with a plurality of impurity discharge holes, which are respectively opened on the upper part of the two secondary separation plates.

[0014] Compared with the prior art, this utility model provides a high-concentration wastewater treatment device, which has the following features:

[0015] Beneficial effects:

[0016] 1. This utility model adopts a multi-stage separation design. First, high-concentration wastewater undergoes primary separation through staggered inclined separation nets and baffles, effectively intercepting large particulate impurities. Simultaneously, the pre-filtered wastewater is discharged through water guide holes. Subsequently, the wastewater enters the secondary separation stage. Through the design of curved diversion baffles, the flow velocity difference causes small particulate impurities to settle and be discharged in a concentrated manner, significantly improving the impurity removal efficiency and enhancing the treatment effect.

[0017] 2. In the secondary separation process, the design of the curved diversion baffle in this invention optimizes the flow path of the wastewater, increasing the flow velocity of the upper layer and slowing it down in the lower layer, thus promoting the natural settling of heavier impurities. The settled impurities enter the guide tank through the discharge hole and are finally collected in the impurity tank for discharge. No additional power is required, which not only improves the separation accuracy but also reduces the equipment's operating costs.

[0018] 3. After initial separation, the wastewater of this invention enters the sedimentation chamber, where tiny suspended solids are further precipitated under low-speed flow conditions, improving the water purification effect. Subsequently, the upper layer of clear water enters the filtration chamber under the action of a suction pump, and after being pressurized, it is forced to pass through multiple layers of filter plates to ensure that residual impurities are completely removed, significantly improving the treatment quality and enabling the treated wastewater to meet discharge standards.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides, for example Figures 1-5The high-concentration wastewater treatment device shown includes a water guide hopper 1, a primary separation pipe 2 connected to the lower end of the water guide hopper 1, a downward-opening external water guide pipe 3 connected to the outside of the primary separation pipe 2, with the opening of the external water guide pipe 3 located at the lower front side, a waste discharge pipe 4 connected to the lower end of the primary separation pipe 2, with the lower opening of the waste discharge pipe 4 inclined backward, a separation filter box 5 installed at the lower end of the external water guide pipe 3, with the opening of the external water guide pipe 3 located inside the separation filter box 5 and fixedly connected to the separation filter box 5, a drain pipe installed at the lower front side of the separation filter box 5, a first sewage discharge pipe installed at the rear left side of the separation filter box 5, a sludge trough 6 installed at the right end of the separation filter box 5, and a second sewage discharge pipe installed at the lower front side of the sludge trough 6, two vertically distributed secondary separation plates 10 installed inside the upper end of the separation filter box 5, with gaps left between the two secondary separation plates 10 and the inner walls of the front and rear ends of the separation mesh 7, respectively, and a sedimentation chamber 14 installed inside the rear end of the separation filter box 5. The front end of the tank 5 is equipped with a filter chamber 15. During the treatment of high-concentration wastewater, the high-concentration wastewater is introduced into the primary separation pipe 2 through the guide bucket 1 for primary separation, which separates large impurities from the wastewater. The separated wastewater is then introduced into the separation filter tank 5 through the outer guide pipe 3, while the large impurities are discharged through the discharge pipe 4. After the wastewater is introduced into the separation filter tank 5, it undergoes secondary separation through two secondary separation plates 10, which separates small impurities from the wastewater. The small impurities are then collected in the sludge tank 6 and discharged through the second drain pipe. After being separated from the lower impurities by the two secondary separation plates 10, the wastewater is introduced into the sedimentation chamber 14, where impurities are deposited. The deposited impurities are discharged through the first drain pipe and finally introduced into the filter chamber 15 for impurity filtration. The filtered water is then discharged through the drain pipe, thus treating the high-concentration wastewater into water that meets the discharge standards.

[0027] Preferably, multiple downward-sloping separation nets 7 are fixedly connected to the inner walls of both the front and rear ends of the primary separation pipe 2, with the front and rear separation nets 7 interlacing with each other. Multiple upward-sloping baffles 8 are fixedly connected to the inner walls of both the front and rear ends of the primary separation pipe 2, with the front and rear baffles 8 interlacing with each other and connected to the respective separation nets 7. Water guide holes 9 are provided on the outer walls of both the front and rear ends of the primary separation pipe 2, and the multiple water guide holes 9 are respectively located between the connected separation nets 7 and baffles 8. In the process of separating high-concentration wastewater, multiple separation nets 7 are set at an angle downwards and are staggered on the inner walls of the primary separation pipe 2. Multiple baffles 8 are set at an angle upwards and are connected to the multiple separation nets 7. Therefore, the wastewater can fall through the separation nets 7 onto the upper end of the baffles 8 and be guided into the outer water pipe 3 through the water guide holes 9. Large impurities cannot pass through the mesh of the separation nets 7 and are blocked. They roll down through the outer walls of the multiple separation nets 7 into the discharge pipe 4, thereby separating the wastewater from the large impurities.

[0028] Preferably, multiple diversion baffles 11 are fixedly connected to the upper ends of both secondary separation plates 10. These baffles 11 are curved in the direction of wastewater flow. Multiple discharge holes 12 are provided on the lower side of each baffle 11, and these holes 12 are respectively located on the upper ends of the two secondary separation plates 10. Guide grooves 13 are provided inside each of the two secondary separation plates 10, and the right ends of both guide grooves 13 extend into the wastewater tank 6. The discharge holes 12 communicate with the two guide grooves 13, thus facilitating the secondary separation of wastewater. During the process, since the multiple diversion baffles 11 are curved along the direction of wastewater flow, the wastewater flow velocity at the upper end of the diversion baffle 11 is greater than that at the lower end of the diversion baffle 11. Also, the larger impurities will sink. When the wastewater flows over the upper end of the secondary separation plate 10, the impurities will slide along the outer wall of the diversion baffle 11 and fall to the lower end of the diversion baffle 11 at the upper edge of the diversion baffle 11. They will then enter the guide tank 13 through multiple discharge holes 12, thereby separating the small impurities in the wastewater.

[0029] Preferably, a partition chamber 16 is provided between the sedimentation chamber 14 and the filtration chamber 15, and the upper sides of the sedimentation chamber 14 and the partition chamber 16 are interconnected. The sedimentation chamber 14, the filtration chamber 15 and the partition chamber 16 are all located below the two secondary separation plates 10, and the upper end of the filtration chamber 15 is sealed by the lower side. A suction pump 17 is provided between the filtration chamber 15 and the partition chamber 16. Multiple filter plates 18 are provided inside the filtration chamber 15. When wastewater enters the sedimentation chamber 14 through the two secondary separation plates 10, since the upper sides of the sedimentation chamber 14 and the partition chamber 16 are interconnected but the lower sides are not connected, the flow velocity of the wastewater in the lower end of the sedimentation chamber 14 is relatively small. This causes impurities that are not separated in the secondary separation to be deposited in the lower end of the sedimentation chamber 14, further separating the impurities. The deposited wastewater is then introduced into the partition chamber 16 through the front side of the upper end of the sedimentation chamber 14 for separation.

[0030] At this time, the wastewater entering the partition chamber 16 will be drawn into the filter chamber 15 by the suction pump 17. The suction pump 17 increases the water pressure inside the filter chamber 15, allowing the wastewater to force its way through multiple filter plates 18, thus performing multi-layer filtration on the wastewater so that it meets the discharge standards and is finally discharged through the drain pipe.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
