[0018] The aeration device 2 includes a fixed bracket 17, a fan 18, an air pipe 19, an aeration box 20 and a release hole 21. The fan 18 is fixedly installed on the top of the fixed bracket 17, one end of the air pipe 19 is fixedly connected to the output end of the fan 18, and the other end of the air pipe 19 is fixedly connected to the middle of one side of the aeration box 20, and the release holes 21 are evenly arranged on the side of the aeration box 20 away from the air pipe 19.

[0019] The fixed bracket 17 is fixedly installed at one end of the grit tank 3 close to the conical sludge tank 4, the air supply pipe 19 is fixedly plugged into the end of the grit tank 3 close to the conical sludge tank 4, the aeration box 20 is fixedly connected to the inner side of one end of the grit tank 3 close to the conical sludge tank 4, and the air is released into the grit tank 3 through the release hole 21, so that the air pushes the sewage to flow upward along the inclined surface of the second baffle 8.

[0020] The bottom end of the grit chamber 3 is inclined, and the first baffle 7 and the second baffle 8 are both inclined, and the inclination angle of the second baffle 8 to the horizontal plane is greater than the inclination angle of the first baffle 7. The blocking of the first baffle 7 and the inclination of the second baffle 8 facilitate the control of the oblique upward flow of sewage, and the first baffle 7 guides the sludge carried by the water flow below into the conical sludge tank 4.

[0021] The horizontal position of the aeration box 20 is located above the first baffle 7, so that the air can push the water flow to avoid the first baffle 7 to make the water flow smoother and facilitate the sludge deposited on the top of the first baffle 7 to slide downward.

[0022] Working principle: During use, the sewage is injected into the grit tank 3 through the water inlet pipe groove 11. When the sewage covers the second baffle 8, the injection is stopped. At this time, the fan 18 is started, and the fan 18 inputs air into the air pipe 19. The air pipe 19 inputs air into the aeration box 20 and discharges the sewage in the aeration box 20. After the sewage in the aeration box 20 is completely discharged, the air enters the grit tank 3 through the release hole 21. The air entering the grit tank 3 pushes the sewage to flow. Due to the inclined setting of the second baffle 8, the sewage flows obliquely upward through the top of the second baffle 8. When the sewage between the aeration box 20 and the second baffle 8 is reduced, the sewage on the other side of the second baffle 8 flows into the aeration box 20 and the second baffle 8 through the bottom end of the first baffle 7. During the flow The sewage pushes the deposited sludge to the top of the conical sludge tank 4. At the same time, since the bottom end of the grit tank 3 is inclined, the sludge falls into the conical sludge tank 4 under the action of gravity and the push of sewage. In this way, aeration promotes the circulation of sewage and accelerates the deposition and collection of sludge. Then the electric push rod 14 is turned on to start the contraction. The top of the electric push rod 14 drives the lifting plate 16 to move upward. The movement of the lifting plate 16 drives the gate 15 to move upward to the top. At this time, the sewage is continuously injected into the grit tank 3 through the water inlet pipe groove 11. The grit tank 3 continues to maintain aeration flow and grit. The sewage after grit settling flows to the next sewage treatment tank through the drainage pipe groove 10. When the sludge in the conical sludge tank 4 is full, the valve 6 is turned by external force to open the channel and the sludge is discharged through the sewage pipe 5.
