[0050] For example, as shown in Figures 1-12 The mud discharging mechanism 6 comprises a first mud pushing plate 601, a second mud pushing plate 602, a first connecting rod 603, a first sliding rail 604, a second sliding rail 605, a second connecting rod 606, a first bottom plate 611, a second bottom plate 612, and a connecting seat 701.

The device can push and discharge the sludge and sediment after the wastewater is discharged. Compared with the manual cleaning of sludge and sediment by workers in the prior art, the device can reduce the labor intensity of workers when cleaning the sludge and sediment subsequently. Meanwhile, the reciprocating swing of the mud discharging plate 608 can promote the discharge of the sludge and sediment on its surface, preventing the discharged sludge and sediment from staying on the mud discharging plate 608 and affecting the discharging and cleaning effect.

[0051] As Figures 1-12As shown, it shows that in another embodiment of the present application, the adsorption tank 7 comprises: activated carbon filter plate 705, connecting block 706, connecting rod 707, cam 708, motor two 710, the activated carbon filter plate 705 is fixedly connected at the top of the connecting seat 701, the connecting block 706 is fixedly connected at the right side of the connecting seat 701, the connecting rod 707 is rotatably connected in the connecting block 706, the motor two 710 is fixedly connected at the bottom of the tank body 1, the cam 708 is fixedly connected at the output end of the motor two 710, the connecting rod 707 is rotatably connected at the surface of the cam 708, the adsorption tank 7 further comprises: gear 702, reciprocating screw rod 703, push rod 704, rack groove 709, the gear 702 is rotatably connected in the connecting seat 701, the reciprocating screw rod 703 is fixedly connected in the gear 702, the push rod 704 is movably connected at the circumferential surface of the reciprocating screw rod 703, the rack groove 709 is fixedly connected at the inner wall of the tank body 1. The gear 702 is engaged with the rack groove 709, the reciprocating screw rod 703 is rotatably connected at the bottom of the connecting seat 701, the cam 708 is rotatably connected at the bottom of the inner wall of the tank body 1, the space in the activated carbon filter plate 705 is provided with modified activated carbon powder for specific pollutants (such as sulfur modified mercury removal, iron oxide modified arsenic removal), so that the activated carbon filter plate 705 can be contacted with wastewater, and many odors in wastewater are derived from harmful chemicals, such as ammonia nitrogen, hydrogen sulfide, etc. These substances not only produce odor, but also pollute the water body, activated carbon can adsorb these harmful substances, reduce environmental pollution, at the same time, through the reciprocating push rod 704, the activated carbon in the activated carbon filter plate 705 can be turned over, further improve the contact area between activated carbon and wastewater, improve the effect of activated carbon on odor adsorption.

[0052] In some examples, after the sewage is fully settled, the water extraction assembly 4 extracts the water to the adsorption tank 7. The motor two 710 starts to drive the cam 708 to rotate. The rotation of the cam 708 drives the connecting rod 707 to move along the circumferential direction of the cam 708. The movement of the connecting rod 707 drives the connecting block 706 to move. The movement of the connecting block 706 drives the connecting seat 701 to move. The connecting seat 701 is constrained by the slide rail two 605 and can only reciprocate along the direction of the slide rail two 605. When the connecting seat 701 moves to the left side of the tank body 1, it will drive the connecting rod one 603 and the slide rail one 604 to move to the left. The connecting rod one 603 pushes the mud pushing plate one 601, and the slide rail one 604 pushes the mud pushing plate two 602 to move. The mud pushing plate one 601 pushes the settled sludge from the bottom plate two 612 to the bottom plate one 611, and the mud pushing plate two 602 pushes the sludge from the bottom plate one 611 to the discharge port 3 for discharge. Thus, the sludge and sediment after the wastewater is discharged can be pushed out. Compared with the manual cleaning of sludge and sediment in the prior art, the device can reduce the labor intensity of workers when cleaning the sludge and sediment subsequently. Meanwhile, in the process of moving the connecting rod two 606 to the left, the protrusion two 609 will touch the protrusion one 607 to continuously move the protrusion two 609, which will extrude the protrusion one 607. The extrusion of the protrusion two 609 on the protrusion one 607 makes the mud plate 608 in contact with it deviate downward and compress the elastic stop block 610 in contact with the mud plate 608. When the connecting seat 701 moves back, the mud pushing plate two 602 pushes the sludge pushed down by the mud pushing plate one 601 to the gap between the bottom plate one 611 and the bottom plate two 612 and falls to the mud plate 608. At the same time, the protrusion two 609 moves away from the protrusion one 607, the elastic stop block 610 is reset without constraint, and the reciprocating swing of the mud plate 608 can promote the sludge and sediment on its surface to be discharged, preventing the discharged sludge and sediment from staying on the mud plate 608 and affecting the discharge cleaning effect.

[0053] When the connecting seat 701 moves reciprocally, it drives the activated carbon filter plate 705 to move, so that the activated carbon filter plate 705 can be in contact with the wastewater. Many odors in wastewater are caused by harmful chemicals such as ammonia nitrogen and hydrogen sulfide. These substances not only produce odors but also pollute the water body. Activated carbon can adsorb these harmful substances and reduce environmental pollution. Meanwhile, the reciprocating movement of the connecting seat 701 drives the gear 702 to move. The gear 702 is engaged with the rack groove 709 and rotates with the movement. The rotation of the gear 702 drives the reciprocating lead screw 703 to rotate, and the rotation of the reciprocating lead screw 703 drives the push rod 704 to move reciprocally. The push rod 704 stirs the activated carbon powder in the activated carbon filter plate 705. The reciprocating movement of the push rod 704 can stir the activated carbon in the activated carbon filter plate 705, further increasing the contact area between the activated carbon and the wastewater and improving the effect of activated carbon on odor adsorption.
