Description

Technical Field

[0001] The invention relates to the field of wastewater treatment, in particular to an environmentally friendly wastewater treatment device for highway construction. Background Art

[0002] During the construction of buildings, roads, bridges, pipelines and other projects, construction materials such as concrete, bricks, asphalt and cement will generate wastewater. Construction wastewater contains a large amount of suspended matter, dust, organic matter, etc. If it is directly discharged into the surrounding water bodies, it will seriously pollute the water quality and affect the water ecological environment.

[0003] When treating construction wastewater, existing wastewater treatment devices usually use sedimentation agents to treat suspended matter and turbidity in the wastewater. The positive and negative charged groups in the sedimentation agent can interact with the suspended matter particles in the water, causing the surface electrical properties of the particles to change, so that the particles attract each other to form flocs, thereby achieving solid-liquid separation in the wastewater. However, the separated solid mixture will sink to the bottom of the device. If the separated water is directly extracted, the solids will also be discharged from the drain pipe with the water flow or blocked at the end of the drain pipe. As the amount of wastewater injected increases, if the solids in the device are taken out, the water storage capacity of the device will also be reduced, making it difficult to ensure continuous treatment of the wastewater.

[0024] Example 4: Please refer to Figure 2 and Figure 8This embodiment further illustrates other embodiments. The feeding assembly shown in the figure includes a feeding air pump 31 rotatably mounted on the top of the injection pipe 6. The sedimentation agent can enter the injection pipe 6 from the pipe on the top of the feeding air pump 31. The feeding air pump 31 inhales the outside air through a one-way air inlet valve, and inputs the sedimentation agent into the injection pipe 6 by pushing the air. The injection pipe 6 is rotatably mounted on the top of the treatment tank 2. The bottom of the injection pipe 6 is a conical structure. A plurality of discharge nozzles 32 symmetrically distributed in the center are fixedly mounted on the bottom of the injection pipe 6.

An exhaust valve 37 is fixedly installed on the outer side of the treatment tank 2 to facilitate the discharge of gas in the treatment tank 2.

[0025] Working principle: First, the staff injects the wastewater from the water injection pipe 3 into the treatment tank 2, and stores the wastewater through the treatment tank 2 and the water storage cylinder 8 directly below the treatment tank 2. Then, the staff injects the sedimentation agent into the feeding air pump 31, so that the feeding air pump 31 injects air into the injection pipe 6, and the sedimentation agent moves rapidly downward along the inner side of the injection pipe 6 with the airflow, and then is discharged from the discharge nozzle 32, so that the sedimentation agent is injected into the wastewater along with bubbles. At the same time, the staff starts the second motor 34, so that the second motor 34 drives the injection pipe 6 to rotate through the third gear 35, and the injection pipe 6 drives the discharge nozzle 32 and the stirring rod 36 to rotate synchronously. The precipitant is evenly mixed with the wastewater, and the solid and liquid in the wastewater are separated, and the solid mixture sinks into the water storage cylinder 8. Then, the staff opens the drain pipe 5 to discharge the treated water through the drain pipe 5, and starts the first motor 10. The first motor 10 drives the mounting frame 7 to rotate, so that the mounting frame 7 drives multiple water storage cylinders 8 to perform circular motion synchronously, and the water storage cylinder 8 containing the solid mixture moves along the bottom inner wall of the device housing 1 and the bottom of the treatment tank 2, so that the water storage cylinder 8 containing the solid mixture moves to the top of the filter screen 21, and the residual water in the water storage cylinder 8 enters the water storage tank 20 through the filter screen 21, so that the drainage pump 40 The water in the water storage tank 20 is input into the drain pipe 5 and then discharged from the drain pipe 5. At the same time, another water storage cylinder 8 moves to the bottom of the treatment tank 2, and the staff can inject the waste water into the treatment tank 2 again for treatment. When the first motor 10 runs again, the water storage cylinder 8 filled with the solid mixture can move to the top of the discharge trough of the device housing 1. At the same time, the water storage cylinder 8 drives the positioning slip ring 14 to move along the inner side of the annular box 13, so that the positioning slip ring 14 drives the first gear 18 at the top of the driven rod 16 to contact the gear ring 19. The first gear 18 can drive the driven rod 16 to rotate during the movement, so that the driven rod 16 drives The push plate 17 moves along the inner side of the water storage cylinder 8, and uses the inclined surface of the push plate 17 to discharge the solid mixture into the discharge trough. The solid mixture falls onto the conveyor belt 23, so that the receiving plate 24 receives the solid mixture. At the same time, the first motor 10 drives the transmission rod 28 to rotate through the gear transmission box 29, and the transmission rod 28 drives the corresponding installation rod 25 to rotate through the synchronous belt 30. The installation rod 25 drives the two toothed belts 22 to rotate and move through the third gear 35, so that the toothed belts 22 drive the conveyor belt 23 to move synchronously, pushing the solid mixture downward. As a result, the treatment tank 2 can continuously treat the wastewater, thereby improving the wastewater treatment efficiency.
