Compared with the existing structure, the present invention has the following beneficial effects:

1. By providing a sewage treatment mechanism, when the cavity formed by the two baffles contains enough sewage, the weight of the sewage presses the baffles to rotate, so that the cavity formed by the other two baffles in sequence corresponds to the outlet of the sedimentation tank, and the sewage continues to flow into another cavity formed by the two baffles, so that the sewage in each cavity formed by the two baffles is equal. When the cavity formed by the two baffles is directly opposite to the outlet of the flocculant tank, the ball valve is just in an open state, and the flocculant in the flocculant tank flows into the cavity formed by the two baffles, so that the flocculant flowing into each cavity formed by the two baffles is equal, thereby achieving the purpose of equal mixing of sewage and flocculant, making the sewage and flocculant mixed more evenly and the coagulation effect of suspended matter in the sewage better;

2.

The connecting rod A shrinks toward the inside of the connecting tube with the piston, pulling the sweeping plate to rotate, so that the sweeping plate can smoothly sweep over the upper surface of the activated carbon tank, sweeping the large particle flocculent above the activated carbon tank to one side of the activated carbon tank. When the sweeping plate is separated from the activated carbon tank, the sweeping plate is reset under the action of the spring force, so that the connecting rod A and the piston are reset. The connecting rod A pushes the sweeping plate to reset to an inclined state, and the pollutants adhering to the sweeping plate are thrown out. The gas accumulated inside the connecting tube is ejected from the telescopic tube into the guide cavity, and then ejected from the pollutant collecting cavity. The gas ejects the pollutants inside the pollutant collecting cavity, and prevents the pollutants from adhering to the sweeping plate.

3. When the sweeping plate contacts the spring sheet, the sweeping plate pushes the spring sheet to move, thereby causing the activated carbon tank to rotate along the arc slide rails A and B. When the magnetic slider and the conductive block slide to one side of the arc slide rail A and the other side of the arc slide rail B respectively, the rubber protrusion on one side of the conductive block collides with the micro switch, and the micro switch turns on the power supply of the electromagnet block. The electromagnet block generates a magnetic force that is the same as the magnetic slider, pushing the magnetic slider to reset, thereby causing the conductive block and the activated carbon tank to reset. This reciprocating process causes the activated carbon tank to continuously swing back and forth along the arc slide rails A and B, thereby improving the efficiency of sewage passing through the activated carbon tank. When the conductive block contacts the conductive sheet, the micro motor circuit is connected, and the micro motor drives the impeller to rotate, thereby generating negative pressure inside the guide tank, further accelerating the efficiency of sewage passing through the activated carbon tank.

When the cavity formed by the two baffles 2031 is facing the outlet of the flocculant tank 102, the ball valve 1021 is just in the open state, and the flocculant in the flocculant tank 102 flows into In the cavity formed by the two baffles 2031, the flocculant flowing into each cavity formed by the two baffles 2031 is repeated in this way, so that the amount of flocculant flowing into each cavity formed by the two baffles 2031 is equal, thereby achieving the purpose of mixing the sewage and the flocculant in equal proportions, making the sewage and the flocculant mixed more evenly, and the flocculant condenses the suspended pollutants in the sewage into large-particle flocs, and the sewage enters the activated carbon tank 201 through the leakage hole A on the upper surface of the activated carbon tank 201, and after being filtered by the activated carbon in the activated carbon tank 201, it flows out from the leakage hole B on the surface of the cover plate 214, and then passes through the sewage sweeping plate 214. 04 sweeps the large particle floccules above the activated carbon tank 201 to one side of the activated carbon tank 201, and then the floccules fall from the sewage outlet into the sewage collecting tank 104. When the sewage sweeping plate 204 is separated from the activated carbon tank 201, the sewage sweeping plate 204 is reset under the action of the spring force, so that the connecting rod A2044 and the piston 2045 are reset. The connecting rod A2044 pushes the sewage sweeping plate 204 to reset to an inclined state, and the gas accumulated in the connecting cylinder 2043 is ejected from the telescopic tube into the guide cavity 2042, and then ejected from the sewage collecting cavity 2041. The gas The pollutants in the dirt collecting chamber 2041 are ejected, and the pollutants adhering to the dirt collecting chamber 2041 are cleaned. The dirt collecting chamber 2041 increases the contact area between the dirt sweeping plate 204 and the flocculants, and the flocculants are cleaned better. When the dirt sweeping plate 204 contacts the spring 2011, the dirt sweeping plate 204 pushes the spring 2011 to move, thereby causing the activated carbon tank 201 to rotate along the arc slide rail A205 and the arc slide rail B206. When the magnetic slider 2012 and the conductive block 2013 slide to one side of the arc slide rail A205 and the arc slide rail B206, respectively, the magnetic slider 2012 and the conductive block 2013 slide to one side of the arc slide rail A205 and the arc slide rail B206. When the conductive block 2013 moves to one side of the arc-shaped slide rail B206, the rubber protrusion on one side of the conductive block 2013 collides with the micro switch 2062, and the micro switch 2062 connects the power supply of the electromagnet block 2051. The electromagnet block 2051 generates a magnetic force identical to that of the magnetic slider 2012, pushing the magnetic slider 2012 to reset, thereby resetting the conductive block 2013 and the activated carbon tank 201, and so on, so that the activated carbon tank 201 continuously swings back and forth along the arc-shaped slide rail A205 and the arc-shaped slide rail B206, thereby improving the efficiency of sewage passing through the activated carbon tank 201. When the conductive block 2013 contacts the conductive sheet 2061, the circuit of the micro motor 2071 is connected, and the micro motor 2071 drives the impeller 2072 to rotate, so that negative pressure is generated inside the guide groove 1031, which further accelerates the efficiency of sewage passing through the activated carbon groove 201. Finally, the staff opens the sealing plate 1032, unscrews the cover plate 2014, and discharges the activated carbon inside the activated carbon groove 201. Then, the sealing plate at the activated carbon filling port is removed, and new activated carbon is filled into the activated carbon groove 201 to achieve the purpose of replacing the activated carbon.
